Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Fig. 1 is a flowchart of an information display method provided by an embodiment of the present invention, where the embodiment may be applied to a scenario where a three-dimensional model of an object such as an article, a commodity, or an object is displayed on a terminal page. For example, in the case where the three-dimensional model of the commodity is displayed on the top page of the APP or the commodity detail page. The method can be executed by an information display device integrated in an intelligent terminal, the device can be realized by software and/or hardware, and the intelligent terminal can be a mobile terminal such as a mobile phone, a tablet personal computer (PAD), a wearable device and the like, a personal computer (PC, personal Computer) and the like. As shown in fig. 1, the method specifically includes the following steps:

And S110, rendering and displaying the three-dimensional model of the target object in a preset display area of the current page at a first rendering view angle.

Alternatively, the current page may include a home page, an item detail page, a live page, a comment page, or a waterfall page of the application. The preset display area may be an area for displaying the target object in the current page. The target object may comprise a commodity. Rendering perspective refers to the angle and position at which a scene is observed and rendered during rendering. In the rendering process, the position parameters of the virtual camera are used, and images with different visual angles can be rendered by adjusting the position parameters of the virtual camera. The virtual camera is used for simulating the behavior of a real camera in the terminal, capturing and recording image information in a virtual scene, and displaying a target object in a two-dimensional plane by rendering the image information. The first rendering perspective may refer to a rendering perspective used when rendering and displaying the three-dimensional model of the target object at any time, for example, the any time may be an initial time when rendering and displaying the three-dimensional model of the target object at the current page.

S120, responding to the detection of the view angle conversion trigger event, and acquiring event data corresponding to the view angle conversion trigger event.

The visual angle conversion triggering event comprises a terminal gesture change event of the current terminal and/or a body gesture change event of the current user, event data corresponding to the terminal gesture change event comprises terminal gesture data, and event data corresponding to the body gesture change event comprises body gesture data.

For example, the terminal may be an intelligent terminal, including an electronic terminal device such as a mobile phone, a PAD, a wearable device, a PC, and the like. The terminal gesture change event may be an event in which the position and/or angle of the terminal is changed, resulting in a change in the viewing angle between the user and the terminal. The terminal pose data may include terminal angle data and/or terminal position data before and/or after the terminal pose is changed.

The body posture change event may be an event in which the position and/or angle of a body part of the user changes, resulting in a change in the angle of view between the user and the terminal. The body position data may include body position angle data and/or body position data before and/or after the body position change.

In practical application, the view angle conversion triggering event may be an event of a view angle change between a user and the terminal caused by the gesture change of the terminal, or may be an event of a view angle change between the user and the terminal caused by the gesture change of the user, or may be an event of a view angle change between the user and the terminal caused by the gesture change of both the terminal and the user.

And S130, rendering and displaying the three-dimensional model of the target object at a second rendering view angle based on the event data.

Wherein the first rendering perspective is different from the second rendering perspective. Because the terminal posture or the user body posture changes, the visual angles of the user and the terminal also change, and in order to present the image of the three-dimensional model matched with the changed visual angle, the rendering visual angle of the three-dimensional model of the target object needs to be adaptively adjusted, namely, the first rendering visual angle is adjusted to be the second rendering visual angle, so that the visual display effect is improved.

Fig. 2 is a schematic illustration of a three-dimensional model of a target object at different rendering angles according to an embodiment of the present invention. In the presentation shown in fig. 2, the user body posture remains unchanged and the terminal posture changes. As shown in fig. 2, an exemplary, intermediate rendering presentation is a rendering presentation of a three-dimensional model of any commodity at rendering perspective 1. When the rendering display diagram on the left side is that the terminal tilts (or rotates) leftwards, rendering display is carried out on the three-dimensional model of the commodity at the rendering view angle 2. When the right rendering display diagram is that the terminal is inclined (or rotated) to the right, rendering display is carried out on the three-dimensional model of the commodity at the rendering view angle 3.

Fig. 3 is a schematic illustration of a three-dimensional model of a target object at yet another different rendering perspective provided in accordance with an embodiment of the present invention. In the presentation shown in fig. 3, the user's body posture changes and the terminal posture does not change. As shown in fig. 3, an exemplary, intermediate rendering presentation is a rendering presentation of a three-dimensional model of any commodity at rendering perspective 4. The rendering display diagram on the left side is that when the body, the head or the eyes of the user move leftwards, the three-dimensional model of the commodity is rendered and displayed at the rendering view angle 5. The right rendering display diagram is that when the body, the head or the eyes of the user move rightwards, the three-dimensional model of the commodity is rendered and displayed at the rendering view angle 6.

The rendering view angle of the three-dimensional model of the commodity is adjusted along with the gesture change of the terminal and/or the user, commodity model details of different angles can be checked, the accuracy and the immersive performance of the user in observing the commodity are improved, the commodity display angle can be always associated with the view angle of the user, the real commodity display mode can be simulated, and the visual experience is improved.

According to the technical scheme, a three-dimensional model of a target object is rendered and displayed at a first rendering view angle in a preset display area of a current page, event data corresponding to a view angle conversion trigger event is obtained in response to detection of the view angle conversion trigger event, wherein the view angle conversion trigger event comprises a terminal posture change event of the current terminal and/or a body posture change event of a current user, the event data corresponding to the terminal posture change event comprises terminal posture data, the event data corresponding to the body posture change event comprises body posture data, the three-dimensional model of the target object is rendered and displayed at a second rendering view angle based on the event data, the first rendering view angle is different from the second rendering view angle, the problem that in the prior art, the target object is fixed in display angle and cannot be dynamically adjusted along with the view angle conversion of a user is solved, the fact that the rendering view angle of the target object is adjusted along with the posture change of the terminal and/or the user can be checked, the accuracy and the immersion of the object observed by the user can be improved, the object display angle can be always associated with the user view angle, the real object display mode can be simulated, and the technical effect of visual experience can be improved.

In an alternative implementation of the embodiment of the present invention, S110 may have a variety of implementations. The method comprises the steps of rendering and displaying a three-dimensional model of a target object at a first rendering view angle in a preset display area of a current page, wherein rendering and displaying the three-dimensional model of the target object at the first rendering view angle in an information display window of the current page, or rendering and displaying the three-dimensional model of the target object at the first rendering view angle outside the information display window of the current page, wherein one part of the three-dimensional model is located in the information display window of the current page, and the other part of the three-dimensional model is located outside the information display window of the current page.

The information display window may be a display window in the current page for displaying the target object information. In the information display window of the current page, rendering and displaying the three-dimensional model of the target object at the first rendering view angle, which can be understood as rendering and displaying the three-dimensional model of the target object at the first rendering view angle in a fixed display window. That is, the display of the target object does not exceed the information display window of the current page.

And rendering and displaying the three-dimensional model of the target object at a first rendering view angle outside the information display window of the current page, wherein the rendering and displaying of the three-dimensional model of the target object at the first rendering view angle can be understood as jumping out of the information display window. When the three-dimensional model of the target object is displayed outside the information display window of the current page, the three-dimensional model is closer to the current virtual camera relative to the terminal screen. That is, the three-dimensional model is less distant from the current virtual camera than the terminal screen. The distance between any point on the three-dimensional model and the current virtual camera may be smaller than the distance between the terminal screen and the current virtual camera, or the distance between the center point of the three-dimensional model and the current virtual camera may be smaller than the distance between the terminal screen and the current virtual camera.

Or when rendering and displaying the three-dimensional model, one part of the three-dimensional model is positioned in the information display window of the current page, and the other part of the three-dimensional model is positioned outside the information display window of the current page. The three-dimensional model of the target object is partially arranged in the information display window and partially arranged outside the information display window, so that a user can experience various display effects, for example, the characteristics of partial commodities displayed outside the information display window can be highlighted.

In the embodiment of the invention, any one of the three modes can be adopted to render and display the three-dimensional model of the target object. In addition, in the alternative implementation manner of the embodiment of the invention, a plurality of display modes can be combined for use.

Optionally, after the three-dimensional model of the target object is rendered and displayed in the information display window of the current page at the first rendering view angle, the method further comprises the steps of controlling the three-dimensional model of the target object to move from the information display window to the outside of the information display window, selecting pixels outside a preset mask layer in the three-dimensional model to render and display in the three-dimensional model in the moving process of the three-dimensional model of the target object, and skipping the rendering and display of the pixels inside the preset mask layer in the three-dimensional model.

The method comprises the steps of displaying the three-dimensional model of the target object in a dynamic mode, wherein the three-dimensional model is displayed in a window in a rendering mode, and displaying the three-dimensional model in a dynamic mode when a user observes commodities.

In addition, in practical application, the three-dimensional model can be displayed by moving from outside to inside the information display window. Specifically, when the three-dimensional model of the target object is rendered and displayed outside the information display window of the current page at the first rendering view angle, the method further comprises the step of controlling the three-dimensional model of the target object to move inwards from outside the information display window to inside the information display window. The information display window is dynamically displayed from inside to outside or from outside to inside on the three-dimensional model, so that the free display of the target object and the effect of following the dynamic adjustment of the user can be realized. For example, when the terminal approaches the user, a display mode of controlling the three-dimensional model of the target object to move from the inside of the information display window to the outside of the information display window may be adopted. When the terminal is far away from the user, a display mode of controlling the three-dimensional model of the target object to move from the outside of the information display window to the inside of the information display window can be adopted.

Fig. 4A is a schematic view showing an effect of a three-dimensional model dynamic breakthrough window of a target object according to an embodiment of the present invention. Fig. 4A is a schematic diagram of a three-dimensional model of a target object displayed in the information display window. The effect diagram of the right part of fig. 4A is a schematic diagram of the three-dimensional model of the target object displayed outside the information display window of the current page. The three-dimensional model of the control target object moves from inside the information display window to outside the information display window, that is, a process of changing from the left effect diagram to the right effect diagram as shown in fig. 4A. The three-dimensional model of the control target object moves from outside to inside the information display window, i.e., the process of changing from the right effect diagram to the left effect diagram as shown in fig. 4A. Fig. 4B is an example schematic diagram of a three-dimensional model breakthrough window display of a target object, such as a commodity, according to an embodiment of the present invention.

Fig. 5 is an effect diagram of a three-dimensional model presentation of yet another target object provided according to an embodiment of the present invention. As shown in fig. 5, the three-dimensional model of the target object is partially within the information presentation window and partially outside the information presentation window. Fig. 6 is a schematic diagram of a three-dimensional model presentation of a target object according to an embodiment of the present invention. As shown in fig. 6, a three-dimensional model of a target object such as a commodity is partially modeled within the information presentation window, and partially outside the information presentation window.

In the dynamic window breaking display process, in order to further improve the window breaking effect of the model passing through the picture, the visual effect of the model part outside the preset mask layer is achieved to be prominently displayed, in the moving process of the three-dimensional model, pixels outside the preset mask layer in the three-dimensional model are selected to be rendered and displayed, and pixels inside the preset mask layer in the three-dimensional model are skipped to be rendered and displayed.

The preset mask layer can be used for shielding a model part in the preset mask layer in the three-dimensional model so as not to be displayed. The depth value of the preset mask layer may be preset so that the preset mask layer is located above a User Interface (UI) layer. The pre-set mask layer may be transparent or non-transparent and have no color information. In specific rendering, the depth value of the pixel to be rendered on the three-dimensional model is compared with the depth value of the preset mask layer through a rendering pipeline, the pixel with the depth value larger than the depth value of the preset mask layer, namely, the pixel outside the preset mask layer is rendered and displayed, and the pixel with the depth value smaller than the depth value of the preset mask layer, namely, the pixel inside the preset mask layer is skipped and displayed.

Fig. 7 is a schematic diagram showing a three-dimensional model through a preset mask layer according to an embodiment of the present invention. As shown in fig. 7, the outside of the preset mask layer may be understood as a side area of the preset mask layer close to the virtual camera. The inside of the predetermined mask layer may be understood as a side area of the predetermined mask layer away from the virtual camera. As shown in fig. 7, the three-dimensional model part outside the preset mask layer can be rendered and displayed, while the three-dimensional model part inside the preset mask layer is not rendered and displayed, so that the effect that the three-dimensional model passes through the picture and is displayed is realized.

The pre-set mask layer may be transparent or non-transparent. When the preset mask layer is transparent, the preset mask layer can shield the three-dimensional model part in the preset mask layer, but the content of the UI layer in the preset mask layer can be rendered and displayed. When the preset mask layer is non-transparent, the preset mask layer can not only shield the three-dimensional model part in the preset mask layer, but also shield the whole content of the UI layer, namely the content of the UI layer cannot be rendered and displayed. The three-dimensional model can be provided with various display performances by rendering and displaying the three-dimensional model in the information display window of the current page, or moving the three-dimensional model out of the information display window of the current page, when the three-dimensional model is displayed out of the information display window, the three-dimensional model can be used for displaying the three-dimensional model by breaking the three-dimensional model, and when the three-dimensional model is displayed out of the information display window, the three-dimensional model is displayed by moving the three-dimensional model out of the information display window of the current page, or moving the three-dimensional model out of the information display window of the current page, the three-dimensional model is displayed by moving the three-dimensional model out of the information display window, so that the dynamic sense of the broken window can be improved. When the partial model is shielded through the preset mask layer, the window breaking feeling can be further improved, so that a user perceives the effect that the model passes through the picture.

It should be noted that, when the three-dimensional model of the target object is rendered and displayed in the second rendering angle, any rendering and displaying mode may be selected. That is, the three-dimensional model of the target object may be rendered and displayed in the second rendering view angle in a display manner in which the three-dimensional model is in the information display window of the current page, or outside the information display window of the current page, or a part of the three-dimensional model is in the information display window, or outside the information display window of the current page, or inside the information display window.

In order to better explain the specific application effect of the information display method provided by the embodiment of the invention. Fig. 8 is a schematic diagram of performing a first rendering perspective display on a three-dimensional model of a target object, such as a commodity, in an information display window of a current page according to an embodiment of the present invention. Fig. 9 is a schematic diagram of performing a second rendering perspective display on a three-dimensional model of the commodity in an information display window of a current page according to an embodiment of the present invention. As shown in fig. 8 and 9, the three-dimensional model of the target object can be made to dynamically adjust the presentation view angle following the change of the terminal posture or the user posture within the information presentation window.

Fig. 10 is a schematic diagram of performing a first rendering perspective display on a three-dimensional model of a target object, such as a commodity, outside an information display window of a current page according to an embodiment of the present invention. Fig. 11 is a schematic diagram of performing a second rendering view display on a three-dimensional model of the commodity outside an information display window of a current page according to an embodiment of the present invention. As shown in fig. 10 and 11, the three-dimensional model of the target object can be made to follow the change of the terminal gesture or the user gesture outside the information display window to dynamically adjust the display viewing angle.

The three-dimensional model of the article may be controlled to move from inside the information display window to outside the information display window as shown in fig. 8 and 9, or the three-dimensional model of the article may be controlled to move from outside the information display window to inside the information display window as shown in fig. 10 and 11.

Fig. 12 is a flowchart of yet another information display method according to an embodiment of the present invention. As shown in fig. 12, the method includes:

And S510, rendering and displaying the two-dimensional material data associated with the target object by an information display layer in the information display window of the current page, and rendering and displaying the three-dimensional model of the target object by a first rendering view angle by a model display layer in the information display window of the current page.

The two-dimensional material data may be any two-dimensional information data related to the target object, for example, when the target object is a commodity, the two-dimensional material data includes, but is not limited to, information such as one or any of names, brands, prices, characteristics, and functional parameters of the commodity.

The information presentation layer may include at least one presentation layer, and the model presentation layer may also include at least one presentation layer. The depth of different presentation layers within the information presentation window is different, i.e. the different presentation layers have different depth values. When the information display layer comprises a plurality of display layers, the two-dimensional material data associated with the target object can be displayed in multiple layers, so that the target object can be displayed in a more three-dimensional mode.

Alternatively, the model presentation layer may be below or above the information presentation layer. That is, the model presentation layer may have a depth greater than or less than the depth of the information presentation layer. By carrying out layered display on the three-dimensional model and the two-dimensional material data, the stereoscopic impression of commodity display can be improved, and the content behind the screen can be fully expressed.

In the concrete implementation, the background information of the target object can be displayed on a background display layer in the information display window.

The background presentation layer may comprise one or more presentation layers, and the depth of the different presentation layers within the information presentation window is different. The placement background information includes a dynamic image or a static picture or a background three-dimensional model. By adding the background display layer on the basis of the information display layer and the model display layer, the scene adaptability of the commodity can be improved, so that a user can fully know the use scene of the commodity.

Fig. 13 is a schematic diagram of displaying a target object based on multiple display layers according to an embodiment of the present invention. As shown in fig. 13, the target object may be fully expressed by 4 presentation layers, which are an information presentation layer a, an information presentation layer B, a model presentation layer C, and a background presentation layer D in order of increasing depth values from front to back. The target object is rendered and displayed through the multi-depth display layer, so that the three-dimensional display performance of the target object can be improved.

The multi-display-layer synthesized display mode provided by the embodiment of the invention not only can be applied to the information display window of the current page, when the three-dimensional model of the target object is rendered and displayed at the first rendering view angle, but also can be applied to the situation that the three-dimensional model of the target object is rendered and displayed at the first rendering view angle on the current page, wherein one part of the three-dimensional model is positioned in the information display window of the current page, and the other part of the three-dimensional model is positioned outside the information display window of the current page. That is, a portion of the three-dimensional model displayed in the information display window may employ the above-described multi-display layer composite display manner.

S520, responding to the detection of the view angle conversion trigger event, and acquiring event data corresponding to the view angle conversion trigger event.

And S530, rendering and displaying the three-dimensional model of the target object at a second rendering view angle based on the event data, wherein the first rendering view angle is different from the second rendering view angle.

Optionally, rendering and displaying the three-dimensional model of the target object at a second rendering view angle based on the event data comprises rendering and displaying the three-dimensional model of the target object at the second rendering view angle again based on the event data, wherein the display view angle of the three-dimensional model after rendering and displaying at the second rendering view angle has a positive correlation or a negative correlation with a terminal posture change event of a current terminal and/or a body posture change event of the current user, and particularly can be the display view angle of the three-dimensional model, and has a positive correlation or a negative correlation with a terminal posture change direction and/or a body posture change direction. The positive correlation may be that the direction of change of the display view angle of the three-dimensional model is the same as the direction of change of the terminal posture and/or the direction of change of the body posture. The direction of change may be any one or a combination of directions up, down, left, and right. For example, as the terminal and/or user body is rotated to the left, the presentation view of the three-dimensional model is also rotated to the left. As another example, as the terminal and/or user's body is rotated to the right, the presentation view of the three-dimensional model is also rotated to the right. The negative correlation may be that the direction of change of the presentation view of the three-dimensional model is different, such as opposite, from the direction of change of the terminal posture and/or the direction of change of the body posture. For example, as the terminal and/or user body is rotated left, the presentation view of the three-dimensional model is rotated right. As another example, as the terminal and/or user body is rotated to the right, the presentation view of the three-dimensional model is rotated to the left.

It should be noted that, when the three-dimensional model of the target object is rendered and displayed at the second rendering angle, the above-mentioned synthetic display manner of multiple display layers may also be adopted. And when the model display layer comprises a plurality of display layers, each display layer can display one three-dimensional model of the target object, which means that a plurality of three-dimensional models of the target object exist, and for the plurality of three-dimensional models, the rendering view angle needs to be converted from a first rendering view angle to a second rendering view angle so as to promote the whole interactivity.

Fig. 14 is a flowchart of another information display method according to an embodiment of the present invention. As shown in fig. 14, the method includes:

And S710, rendering and displaying the three-dimensional model of the target object in a preset display area of the current page at a first rendering view angle.

Optionally, rendering and displaying the three-dimensional model of the target object at a first rendering view angle in a preset display area of the current page, wherein rendering and displaying the three-dimensional model of the target object at the first rendering view angle is performed in an information display window of the current page, or rendering and displaying the three-dimensional model of the target object at the first rendering view angle is performed outside the information display window of the current page, wherein one part of the three-dimensional model is positioned in the information display window of the current page, and the other part of the three-dimensional model is positioned outside the information display window of the current page.

Optionally, in an information display window of a current page, rendering and displaying a three-dimensional model of a target object at a first rendering view angle, wherein the rendering and displaying comprises an information display layer in the information display window of the current page, rendering and displaying two-dimensional material data related to the target object, and a model display layer in the information display window, rendering and displaying the three-dimensional model of the target object at the first rendering view angle, wherein the information display layer and the model display layer respectively comprise at least one display layer, and the depths of different display layers in the information display window are different.

S720, responding to the detection of the view angle conversion trigger event, and acquiring event data corresponding to the view angle conversion trigger event.

The visual angle conversion triggering event comprises a terminal gesture change event of the current terminal and/or a body gesture change event of the current user, event data corresponding to the terminal gesture change event comprises terminal gesture data, and event data corresponding to the body gesture change event comprises body gesture data. Optionally, the body posture change event comprises an eye posture change event and/or a head posture change event. The event data corresponding to the eye posture change event or the head posture change event includes current eye center point data of the current user.

And S730, determining the view angle offset based on the event data.

The view angle offset represents a second position point of the virtual camera corresponding to the second rendering view angle, and is relative to a position offset of a first position point of the virtual camera corresponding to the first rendering view angle. Since rendering images of different perspectives can be achieved by adjusting the position of the virtual camera, this step requires first determining a positional offset characterizing the position point of the virtual camera after the change relative to the position point of the virtual camera before the change.

Specifically, there are a variety of implementations of S730.

Optionally, when the view angle conversion triggering event includes a terminal gesture change event, the event data includes current gyroscope angle data of a current terminal, the view angle offset is determined based on the event data, the view angle offset is determined based on the current gyroscope angle data and preset correction angle data, terminal deflection direction data is obtained through calculation, and the view angle offset is determined based on the terminal deflection direction data.

The gyro angle data may be data obtained by an angular velocity sensor (i.e., a gyroscope) based on the law of conservation of angular momentum. Specifically, when an object rotates in a certain direction, the gyroscope has one or more tiny rotors which keep the original rotation direction and speed when the terminal rotates, so that the rotation state of the terminal is perceived by measuring the change of the angular speed of the rotors. The current gyroscope angle data may be orientation gesture data of the terminal.

The preset correction angle data may be a preset fixed value, and is used for offsetting the current gyroscope angle data, so that the corrected viewing angle is more convenient for the user to observe. The preset correction angle data may be an angle determined according to a hand-held gesture of the user to the terminal, for example, the value may be 15 degrees.

The terminal deflection direction data may be a difference between the current gyroscope angle data and the preset correction angle data. The deflection direction of the terminal can be accurately identified through the current gyroscope angle data and the preset correction angle data, so that the display angle of the three-dimensional model of the target object can be reasonably adjusted. The terminal deflection direction data is specifically three-dimensional vector data, which may be expressed as (x, y, z), and the viewing angle offset may include lateral data and longitudinal data in the terminal deflection direction data, that is, the viewing angle offset may include x data and y data in the terminal deflection direction data.

Optionally, a second implementation manner of the step S730 is that when the visual angle conversion triggering event comprises a body posture change event and the body posture change event comprises an eye posture change event and/or a head posture change event, the event data comprises current eye center point data of the current user, the visual angle offset is determined based on the event data, the visual angle orientation data of the user is calculated based on the current eye center point data and the screen center point data, and the visual angle offset is determined based on the visual angle orientation data of the user.

The current eye center point data may be data obtained by performing face recognition on a user and acquiring a normal direction of eyes and a screen so as to determine a direction and a position of a user's sight. For example, the current eye center point data is obtained through an augmented reality recognition technology. Illustratively, the current eye center point data may be calculated by the formula eye_center=mv_matrix× (left_eye_position+right_eye_position)/2. Where eye_center is the current eye center point data. left eye position is left eye position. right eye position is the right eye position. MV_matrix is a Model-View Matrix (Model-View Matrix). Mv_matrix is a4×4 Matrix. The eye center may be a three-dimensional vector.

The screen center point data may be a preset value, such as set to (0, 0). The user perspective orientation data may be the difference between the current eye center point data and the screen center point data. So that the viewing angle offset can be determined based on the user viewing angle orientation data. The display angle of the three-dimensional model can be dynamically adjusted along with the change of the eye or head gesture of the user. For example, the view offset may include landscape data and portrait data in the user view orientation data, i.e., the view offset may include x data and y data in the user view orientation data.

Optionally, a third implementation manner of the step S730 is that when the perspective conversion triggering event includes a body posture change event and the body posture change event includes a hand posture change event, the event data includes current hand position point data of the current user, the step of determining the perspective offset based on the event data includes calculating model deflection direction data based on the current hand position point data and the previous hand position point data before the hand posture change, and the step of determining the perspective offset based on the model deflection direction data. For example, the difference between the current hand position point data and the previous hand position point data is used as model yaw direction data, and the view angle offset may include x data and y data in the model yaw direction data.

The current hand position point data of the current user can be position point data of the user on a terminal screen. The model deflection direction data can be determined by determining the data such as the movement position, movement distance and the like of the finger of the user on the terminal screen. Accordingly, the viewing angle offset is determined from the model yaw direction data. The display angle of the three-dimensional model can be dynamically adjusted along with the change of the hand action of the user.

Optionally, a fourth implementation of S730 is to combine at least two of the first, second and third implementations of S730. When the combination is performed, the view angle offset obtained by the combined at least two implementation manners can be vector added to obtain the final view angle offset. For example, when the terminal gesture and the user body gesture are changed, accurate visual angle offset determination is realized.

In addition to the above embodiments, the range of the viewing angle offset may be limited to prevent the rendering distortion. Specifically, after the view angle offset is determined based on the event data and before the three-dimensional model of the target object is rendered and displayed in the second rendering view angle based on the view angle offset, the method further comprises adjusting the view angle offset beyond the preset value range if the view angle offset is beyond the preset value range, so that the adjusted view angle offset is within the preset value range.

The viewing angle offset may include multidimensional data, and a corresponding preset value range may be set for each dimensional data. Illustratively, the preset value range is interval [ -2,2]. In a specific application example, if the viewing angle offset exceeds the range [ -2,2], the viewing angle offset can be adjusted to fall within [ -2,2], so as to avoid distortion of rendering effects. In order to further ensure the rendering effect, when the view angle offset is multidimensional data, the multidimensional data can be adjusted in the same proportion, so that the view angle deflection amplitude is ensured to be the same in each dimension while the data of each dimension falls into [ -2,2].

And S740, rendering and displaying the three-dimensional model of the target object at a second rendering view based on the view angle offset.

The first rendering view angle can be adjusted according to the view angle offset, and the second rendering view angle is obtained. Thus, the three-dimensional model shown at the second rendering perspective is more tailored to the user's viewing angle. There are various ways of performing the first rendering angle adjustment according to the viewing angle offset. For example, a mapping relationship between the view angle offset and the first rendering angle adjustment may be established, and the second rendering view angle may be obtained according to the mapping relationship. Or the relation between the view angle offset in the space and the projection coordinates in the screen can be determined according to theoretical knowledge in computer graphics, so that the first rendering view angle is adjusted, and the second rendering view angle is obtained. By adjusting the rendering view angle of the three-dimensional model according to the view angle offset, the object display can dynamically display along with the view angle of the user, more details can be displayed, and the object display effect similar to the real space is achieved.

In order to simulate a picture observed by a real eyeball, optionally, rendering and displaying the three-dimensional model of the target object at a second rendering view angle based on the view angle offset, wherein the rendering and displaying comprise constructing an off-axis projection matrix based on a perspective projection matrix based on a transverse view angle offset and a longitudinal view angle offset in the view angle offset, determining projection coordinates of the three-dimensional model of the target object based on the off-axis projection matrix, and rendering and displaying the three-dimensional model of the target object based on the projection coordinates.

Wherein the perspective projection matrix is a concept in computer graphics. The perspective projection matrix is used for converting object coordinates in the three-dimensional world into projection coordinates on the two-dimensional screen, so that perspective or orthogonal projection effect is realized. The perspective projection matrix defines a view volume (view frustum) or a view cone (view volume), i.e. a region of the object visible in the viewing space (VIEW SPACE).

Fig. 15 is a schematic view of a view cone provided in accordance with an embodiment of the present invention. As shown in fig. 15, in the perspective projection matrix, clipping planes are defined by six tuples left (left), right (right), top (top), bottom (bottom), near (near), far (far). In addition, parameters such as viewing angle, aspect ratio and the like can be defined in the perspective projection matrix. The shape and size of the view cone can be determined by parameters in the perspective projection matrix, thereby affecting the image rendered on the terminal screen. The basic perspective projection matrix is

In the embodiment of the invention, in order to enable the screen picture to be consistent with the observation angle of a user, the inclined view cone is adopted on the basis of the perspective projection matrix, so that the picture observed by a real eyeball can be simulated. Fig. 16 is a view cone tilt schematic provided in accordance with an embodiment of the invention. As shown in fig. 16, the left side is a normal viewing cone and the right side is an off-axis viewing cone. At the time of the viewing angle conversion trigger event, the change of the rendering viewing angle can be realized based on the off-axis viewing cone shown on the right side in fig. 16, thereby simulating the picture observed by the real eyeball.

When the oblique view cone is realized, an off-axis projection matrix is required to be constructed according to the transverse view angle offset and the longitudinal view angle offset in the view angle offsets on the basis of the perspective projection matrix. For example, the off-axis projection matrix may beWhere x is the lateral viewing angle offset of the viewing angle offsets and y is the longitudinal viewing angle offset of the viewing angle offsets. That is, x is the lateral data in the terminal deflection direction data or the user viewing angle orientation data, and y is the longitudinal data in the terminal deflection direction data or the user viewing angle orientation data.

After the off-axis projection matrix is obtained, the projection coordinates of the three-dimensional model of the target object can be determined according to the screen projection related knowledge in computer graphics, and rendering and displaying are carried out on the three-dimensional model of the target object based on the projection coordinates. By adopting the off-axis projection matrix to conduct three-dimensional model rendering display, the image observed by the real eyeball can be simulated.

It should be noted that, when determining the projection coordinates of the three-dimensional model of the target object based on the off-axis projection matrix and rendering and displaying the three-dimensional model of the target object based on the projection coordinates, the method may be combined with the foregoing multi-display layer display mode and/or window breaking display mode, which is not described herein again.

On the basis of any one of the above embodiments, optionally, the information display method further includes detecting a distance between eyes or a head of a current user and a terminal screen in real time, and adjusting a size of a three-dimensional model of the target object to be displayed currently according to the distance. Specifically, in actual display, a display mode of reducing the size of the three-dimensional model of the target object currently displayed when the distance between the eyes or the head of the current user and the terminal screen increases may be adopted. And/or a display mode of enlarging the size of the three-dimensional model of the target object currently displayed when the distance between the eyes or the head of the current user and the terminal screen is reduced can be adopted. By the method, the display effect of the three-dimensional model of the target object on the near size and the far size can be achieved, so that commodity detail information can be better displayed in the near distance, and commodity whole contour information can be better displayed in the far distance.

It should be noted that, in the technical solution of the present disclosure, the related aspects of collecting, updating, analyzing, processing, using, transmitting, storing, etc. of the personal information (such as terminal gesture data and/or body gesture data) of the user all conform to the rules of relevant laws and regulations, and are used for legal purposes without violating the public welfare. Necessary measures are taken for the personal information of the user, illegal access to the personal information data of the user is prevented, and the personal information security, network security and national security of the user are maintained.
