The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.

The embodiment of the invention provides a method, a device, computer equipment and a computer readable storage medium for realizing a light reflection effect. Specifically, the embodiment of the invention provides a light reflection effect implementation method suitable for a light reflection effect implementation device, and the light reflection effect implementation device can be integrated in computer equipment.

The computer device may be a terminal or the like, including but not limited to a mobile terminal, such as a mobile terminal including but not limited to a smart phone, a smart watch, a tablet computer, a notebook computer, a smart car, etc., and a fixed terminal including but not limited to a desktop computer, a smart television, etc.

The computer device may be a server, which may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network ), and basic cloud computing services such as big data and artificial intelligence platform, but is not limited thereto.

The method for realizing the light reflecting effect can be realized by a server or a terminal and the server together.

The method for realizing the light reflection effect by the terminal and the server is taken as an example, and the method is described below.

As shown in fig. 1, the reflection effect implementation system provided by the embodiment of the present invention includes a terminal 10, a server 20, and the like; the terminal 10 and the server 20 are connected through a network, for example, a wired or wireless network connection, wherein the server 20 may exist as a computer device storing data such as a virtual object model, smoothness, a preset reflective color, and a light incident direction.

Wherein the terminal 10 may be configured to send a display data acquisition request to the server 20 in response to a display instruction of the virtual object model.

The server 20 may be configured to transmit the virtual object model, the smoothness, the preset reflective color, and the light incident direction to the terminal 10 in response to the display data acquisition request.

The terminal 10 may be configured to receive a virtual object model to be added with a light reflection effect, where the virtual object model includes a transparent area, obtains a smoothness corresponding to the transparent area, a preset light reflection color, and a light incidence direction, calculates at least one light reflection area displayed in the light reflection color on the preset light reflection body model based on the smoothness, the light reflection color, and the light incidence direction, obtains a light reflection texture map, where the light reflection texture map includes a light reflection effect texture, fuses the light reflection texture in the light reflection texture map with the light reflection area, and obtains a processed light reflection area having the light reflection texture and the light reflection color, and displays the light reflection effect on the transparent area on the virtual object model based on the processed light reflection area.

It will be appreciated that in some embodiments, the steps performed by the terminal 10 to achieve the light reflection effect may also be performed by the server 20, which is not limited by the embodiment of the present invention.

The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.

The embodiments of the present invention will be described from the perspective of a light reflection effect implementation apparatus, which may be integrated in a server or a terminal in particular.

As shown in fig. 2, the specific flow of the method for implementing the light reflection effect in this embodiment may be as follows:

201. and obtaining a virtual object model with a reflection effect to be added, wherein the virtual object model comprises a transparent area.

The virtual object model is a model of a virtual object which needs to realize a reflection effect. In particular, the virtual object model may be a model of a dynamic or static virtual object.

For example, the virtual object model may be a model of a mirror that is static in the virtual environment; alternatively, the virtual object model may be a dynamic reflective object model, such as a model of a vehicle having a metal housing, or the like.

Specifically, the transparent region is a component of the virtual object model, and is a region in the virtual object model. It should be noted that the transparent region does not mean that the content presented in the transparent region is necessarily presented in a transparent form, but means that when the light reflection effect is not displayed, the transparent region is in a transparent state, and does not affect the light reflection effect to be presented.

Taking the virtual object model as a mirror, as shown in fig. 3, the structure of the whole mirror (i.e., the virtual object model) can be divided into three partial areas from back to front, which are respectively a decorative outer frame, a base drawing capable of showing a mirror looking effect in the mirror, and glass for enabling the surface of the mirror to have a light reflecting effect, wherein the glass partial areas are transparent areas.

It will be appreciated that in fig. 3, the current viewing angle is completely transparent as there is no reflection of the glass surface, which produces a reflection effect when the viewing angle is moved to the front of the mirror.

In some alternative embodiments, in order to add a light reflection effect other than a simple light effect to the virtual object model, the virtual object model may further include an image display area, and the transparent area may be superimposed on the image display area. At this time, the method for implementing the light reflection effect provided by the embodiment of the invention may further include:

and acquiring a target display image corresponding to the virtual object model, and displaying the target display image in the image display area so that the reflection effect in the transparent area is overlapped and displayed on the target display image.

Wherein the target display image may be an image for display in the image display area. Image content of the virtual object model reflecting the virtual scene may be included in the target display image, or some specific image content may be included in the target display image.

The image display area is an area for displaying image contents needing to be superimposed with the reflection effect in the virtual object model. Specifically, the image display area may display some image content by displaying the target display image, and since the transparent area is superimposed on the image display area, the reflective effect may be superimposed on the image content displayed by the image display area through the transparent area.

It will be appreciated that, in addition to the image display area, other areas may be provided in the virtual object model to display some images, but the image content displayed by the other areas displaying images is not superimposed with the reflective effect displayed by the transparent areas.

For example, the region where the base map is located as shown in fig. 3 is the image display region, and the base map is the target display image.

Alternatively, when the transparent region is superimposed on the image display region, a part of the image display region may be covered, or the transparent region may entirely cover the image display region. The transparent region may be the same size as the image display region or may be different from the image display region.

In some examples, the determining, according to the information of the virtual scene, a portion that needs to be reflected by the virtual object model to generate a target display image, where the step of "obtaining the target display image corresponding to the virtual object model" may specifically include:

generating a reflected object image based on a target reflected object in the virtual scene, which needs to be reflected by the virtual object model;

and generating a target display image corresponding to the virtual object model according to the reflected object image and the preset background image.

In particular, the virtual scene may be a virtual environment that an application program displays (or provides) while running on a terminal or server. The virtual scene is any one of a two-dimensional virtual scene and a three-dimensional virtual scene, and the virtual environment can be sky, land, ocean and the like, wherein the land comprises environmental elements such as deserts, cities and the like.

For example, in a 2D card game, the virtual scene may be a scene for displaying a released card or a virtual object corresponding to the displayed card, and the exemplary virtual scene may include: arenas, battle fields, or other "field" elements or other elements that may display the status of card play.

Wherein the target reflective object may be a static object or a controlled dynamic object in the virtual scene. For example, the target reflective object may be a plant, a table and chair, etc. in a virtual scene; alternatively, the target reflective object may be a virtual character, a virtual animal, a cartoon character, or the like.

Specifically, the reflection object image may be an image including only the target reflection object, or the reflection object image may be an image including the target reflection object and a virtual scene of a certain range around the position where the target reflection object is located.

The background image may be a preset image that provides background information for a target reflective object in the reflective object image. In some examples, the background image may be an image of the virtual scene in which the target reflective object is currently located, may be an image of other virtual scenes, or the background image may be empty.

For example, the virtual object model may be a mirror, and one virtual character in the virtual scene may be stored as RT as a target display image. The avatar in RT is movable, e.g., the avatar's actions may change. By displaying RT in the image display area, an effect that the virtual character stands in the mirror, that is, an effect that the virtual character looks in the mirror can be created.

Where RT is a render target, which may also be referred to as a render target, rendering the 3D scene to an intermediate storage buffer or Render Target Texture (RTT).

In the embodiment of the invention, when a game virtual character stands in a scene, a game picture at the moment can be stored as RT, and the RT can be used as a static picture of a base picture. The game virtual character can do any action in the scene, and the game picture is recorded in real time in the RT and then displayed in the image display area of the virtual object model.

RT is understood to be a movie curtain that replaces a fixed target display image. Different content can be played on the movie canvas (i.e., RT), say that a virtual character is walking. It will be appreciated that no model of the avatar may appear in the actual virtual scene, but the avatar's walking content is displayed on the canvas.

In the practical application process, the virtual image reflected by the virtual object model is represented by the target display image in the image display area, and because the virtual image reflected by the virtual object model is not actually directly irradiated by light, the virtual image is darker, in order to reflect the stereoscopic impression of the reflection effect of the virtual object model, the brightness of the target display image can be adjusted, so that the display effect of the target display image in the image display area in the virtual object model is more real, that is, before the step of displaying the target display image in the image display area, the method for realizing the reflection effect provided by the embodiment of the invention further includes:

Acquiring the sight direction of a game player, and determining the sight included angle between the sight direction and the virtual object model;

based on the included angle of the line of sight, predicting the reflection brightness of the display image of the display target through the virtual object model;

and adjusting the image brightness of the target display image according to the reflection brightness to obtain the target display image with the brightness adjusted.

Wherein the line of sight direction may be a viewing direction of the game player. In the process of game making, a camera can be arranged, wherein the direction in which the camera is placed is the viewing direction of a game player, and according to the different positions and angles of the camera, the game object can be viewed from different directions, and in the actual game process, the viewing direction can be understood as the direction perpendicular to the screen displaying the game picture.

The line-of-sight angle may be an angle between the line-of-sight direction and a normal direction of the virtual object model. The virtual object model may include a plurality of pixel points, each pixel point corresponding to a respective normal direction, where the normal direction is a direction perpendicular to a plane in which the pixel point is located.

Specifically, the prediction mode between the included angle of the line of sight and the reflection brightness can be set by a technician according to the actual display requirement. For example, the line of sight angle and the reflected brightness may be linear or nonlinear.

Optionally, when the target display image is adjusted according to the reflection brightness, the brightness of the target display image may be adjusted to the reflection brightness, or the reflection brightness may be mapped according to a preset mapping relationship, so as to obtain the brightness of the target display image to be adjusted, and the specific mapping relationship may be designed by a technician according to the actual display requirement.

In the game, a third person viewing angle is generally adopted, and instead of the game player facing the virtual object model directly under the first person viewing angle, an included angle exists between the player viewing angle and the virtual object model. The brightness of the target display image is also adjusted as a way to create a sense of volume in the art. By using the effect of the target display image with the image brightness adjusted, the display effect of the virtual object model can be better integrated into the scene. For example, for the case of a virtual character looking down on a mirror, the resulting effect may be a more stiff effect similar to the virtual character actually standing inside the virtual scene, rather than directly mapping.

202. And acquiring the smoothness, the preset reflective color and the light incidence direction corresponding to the transparent area.

The smoothness is used for controlling the smoothness of the reflecting surface for realizing the reflecting effect. Taking the virtual object model as a mirror as an example, the smoothness corresponding to the transparent area is the smoothness of the surface of the mirror.

Specifically, the technician can set the color of the light reflecting effect, that is, the light reflecting color according to the actual display requirement. For example, the reflective color may be set to yellow; alternatively, the reflection color may be set to be the same as the color of a certain virtual object in the virtual scene, where the color of the virtual object is the reflection color, and so on.

Wherein the light incident direction is the simulated illumination direction. It will be appreciated that the direction of incidence of light here does not actually produce illumination, but is merely used to calculate the light reflection effect.

For example, the illumination direction may be set for glass, assuming that the light comes from the upper left corner of the virtual object model, and the light comes from the upper left corner regardless of how the virtual object model moves, rotates, and the user's perspective changes. That is, for a virtual object model, the parameters of the light incident direction for the virtual object model are unchanged regardless of how the user switches the viewing angle.

203. Based on the smoothness, the reflection color and the light incidence direction, at least one reflection area displayed in the reflection color on a preset reflector model is calculated.

The reflector model is a preset model for representing the reflecting effect. When the reflection effect needs to be rendered on the virtual object model, the reflection body model or a part of the area of the reflection body model can be displayed through the transparent area of the virtual object model, so that the effect of the reflection effect on the virtual object model is achieved.

Alternatively, the reflector model and the virtual object model may be two different models. For example, the virtual object model may be a model of a mirror that is static in the virtual environment, while the reflector model is a model for achieving a reflection effect in the virtual object model. The reflector model is not included in the virtual object model, but is displayed through transparent areas.

Of course, there may be some correlation between the reflector model and the virtual object model. For example, parameters such as the size of the reflector model may be related to the size of the transparent region of the virtual object model, and so on.

It will be appreciated that since the reflective effect exhibited by the transparent regions is actually obtained by the appearance of the reflector model, the corresponding smoothness of the transparent regions can also be considered as a setting parameter for the smoothness of the reflector model.

Specifically, the light reflecting area is actually obtained by distinguishing the color of a specific area in the reflector model from the color of other areas in the reflector model in the art, but the light reflecting area can be visually obtained by reflecting, scattering and the like of light by the reflector model.

For example, the reflector model and the light reflecting area may be as shown in fig. 4.

It will be appreciated that the retroreflective effect exhibited by the transparent areas may be determined by both the direction of illumination and the viewing angle of the user, and thus the retroreflective effect will change as the viewing angle of the user changes. For example, to achieve the reflection effect of the glass portion, i.e., the transparent region, as shown in fig. 3, the user's viewing angle, i.e., the direction of line of sight, and the direction of incidence of the light rays may be first obtained to calculate the half-distance vector affecting the reflection effect, and then the smoothness and reflection color of the model surface may be obtained to calculate.

In some alternative embodiments, the step of calculating the at least one reflection area displayed in the reflection color on the preset reflector model based on the smoothness, the reflection color and the incident direction of the light ray may specifically include:

calculating a half-range vector of a preset reflector model based on the light incidence direction and the sight direction of a game player;

acquiring normal line information of the reflector model, and determining a normal line direction vector of the reflector model according to the normal line information;

and calculating at least one reflecting area displayed by the reflecting color on the reflecting body model according to the smoothness, the reflecting color, the half-way vector and the normal direction vector.

The viewing direction may be a preset user viewing direction. In the game making process, a camera can be arranged, wherein the placed direction of the camera is a preset user viewing direction, and according to the placed position and angle of the camera, the game object can be viewed from different directions, and in the actual game process, the viewing direction can be understood to be the direction perpendicular to the screen displaying the game picture.

Optionally, the line-of-sight direction may be obtained by subtracting the coordinates of the reflector model in world space from the coordinates of the camera in the preset virtual scene, and normalizing the subtraction result to obtain the direction in which the camera looks at the model (i.e., the line-of-sight direction of the game player).

Wherein the normal information may indicate the normal direction of the reflector model, the normal direction vector being the vector of the normal direction. In general, the target game model may include a plurality of pixels, each pixel corresponding to a respective normal direction, where the normal direction is a direction perpendicular to a plane in which the pixel is located, and in general, the normal vector may be in the form of a unit vector.

Alternatively, the normal information of the reflector model can be transferred from the model space to the world space, and the conversion result is normalized to obtain the normal direction vector. Specifically, the normalization processing, namely normal, can map the data to be processed within the range of-1 to 1, and the normalization processing can enable calculation to be more convenient and rapid.

For example, in the embodiment of the invention, a Blinn-Phong model can be used to calculate the position of the high light point illuminated on the reflector model, namely the reflecting area, through parameters such as smoothness, reflecting color, light incidence direction and the like.

Alternatively, the line-of-sight direction and the light incident direction are added, and the result obtained by normalizing the added result may be used as a half-way direction, i.e., a half-way Vector (Halfway Vector).

The half-range vector is a unit vector in the half direction of the included angle between the light and the line of sight, and the closer the half-range vector is to the normal vector, the larger the specular light component is.

The smoothness, the reflection color, the half-range vector and the normal direction vector are substituted into a Blinn-Phong model, and a reflection area=reflection color x pow (max (0, dot (half-range direction, normal direction)), smoothness) can be calculated by the Blinn-Phong model.

Where pow (x, y) is the power of x to the y of the mathematical operation x, max (x, y) is the maximum of x and y, and dot (x, y) is the dot product of x and y.

The Blinn-Phong illumination model is proposed by Jim Blinn in 1977 on the basis of the conventional Phong illumination model. It is an empirical model and does not fully conform to the illumination phenomenon in the real world. It divides the light entering the camera into three parts, each part using a method to calculate its contribution, the three parts being Ambient light (Ambient), diffuse and Specular (Specular), respectively.

204. And obtaining a reflective texture map, wherein the reflective texture map comprises reflective effect textures.

The reflective texture map is an image comprising reflective effect textures.

Specifically, the retroreflective texture map may be as shown in fig. 5. The retroreflective effect texture, i.e., the texture that embodies the path of travel of the light rays in the retroreflective effect, may provide, for example, a diagonal pattern as shown in fig. 5 and a gradual change of the light rays from top to bottom.

205. And fusing the light reflecting texture in the light reflecting texture map with the light reflecting area to obtain the treated light reflecting area with the light reflecting texture and the light reflecting color.

Wherein, the treated light reflecting area can comprise a texture which presents a certain light reflecting effect by a light reflecting texture with a light reflecting color. For example, the treated retroreflective regions can be as shown in fig. 6.

In some alternative embodiments, if the reflector model is black, the reflector model may obscure effects behind transparent areas in the virtual object model. Therefore, if the area behind the transparent area in the virtual object model needs to display content, the reflector model may have a certain transparency, for example, the other places except the reflective part are transparent, so before the step of displaying the reflective effect on the transparent area on the virtual object model based on the post-processing reflective area, the method for implementing the reflective effect provided by the embodiment of the present invention may further include:

Determining a transparency adjustment channel from the color channels of the reflector model according to the reflection color;

and adjusting the transparency parameter of the reflector model based on the color component of the reflector model in the transparency adjustment channel to obtain a treated reflective area subjected to transparency treatment.

In particular, the color channel may have R, G, B three channels, and R, G, B three channels may be selected as transparency adjustment channels, all of which store color information.

When the transparency adjustment channel is determined, a certain channel can be taken as the transparency adjustment channel according to the proximity degree of the reflection color and each color channel, and the color value and the transparency can be output. For example, assuming that the highlighting color is gold, the color of the R channel is more clearly defined as being more biased to red in red, green and blue, and then the R channel may be selected as the transparency adjustment channel.

For example, the reflection effect achieved by the virtual object model before the transparency is not adjusted may be as shown in fig. 7, that is, the reflection effect on the reflector model only displayed by the virtual object model; the reflection effect of the virtual object model after the transparency is adjusted can be shown in fig. 8, that is, the image display area in the virtual object model can be displayed.

206. And displaying the reflection effect on the transparent area on the virtual object model based on the processed reflection area.

It is understood that the transparent region may display all or only a portion of the treated retroreflective region, and in some examples, a portion of the retroreflective region may also be modeled as an area outside the treated retroreflective region. The embodiment of the invention does not limit the display range of the treated reflecting area in the reflecting body model by the transparent area.

In some optional embodiments, in order to match the display effect of the virtual object model with the virtual environment, the method for implementing the light reflection effect provided by the embodiment of the present invention may further include:

acquiring environment brightness information of a virtual environment;

generating a brightness adjustment image according to the environment brightness information;

and performing model brightness adjustment on the virtual object model based on the brightness adjustment image to obtain a virtual object model with brightness adjusted.

For example, the model brightness of the virtual object model can be reduced according to the environment brightness information, and the virtual object model is gradually darkened from top to bottom through a positive film overlapping processing method.

Taking a rendering tool as a Blender as an example, the positive film overlay in the Blender can multiply the pixel values of all the pixel points by adopting values (namely color processing parameters) between (0.0 and 1.0), so as to realize the fusion calculation of the pixel values of all the pixel points. This operation does not have to be standardized, and a multiplication of two terms between (0.0 and 1.0) always yields results between (0.0 and 1.0).

Alternatively, the color processing parameters may be represented using a "traditional" triplet, such as RGB (124, 255, 56), where the multiplication results in too high a value, such as RGB (7316, 46410, 1848), which can be normalized (recovered) to a value in the range of (0 to 255) by dividing by 256.

As can be seen from the foregoing, the embodiment of the present invention may obtain a virtual object model to be added with a light reflection effect, where the virtual object model includes a transparent region, obtains a smoothness corresponding to the transparent region, a preset light reflection color, and a light ray incidence direction, calculates, based on the smoothness, the light reflection color, and the light ray incidence direction, at least one light reflection region displayed in the light reflection color on the preset light reflector model, and obtains a light reflection texture map, where the light reflection texture map includes a light reflection effect texture, and fuses the light reflection texture in the light reflection texture map with the light reflection region to obtain a processed light reflection region having the light reflection texture and the light reflection color, and displays the light reflection effect on the transparent region on the virtual object model based on the processed light reflection region. In the embodiment of the invention, after the light reflecting area is obtained, the light texture in the light reflecting effect is realized through the light reflecting effect texture in the light reflecting problem map, and a large amount of physical correlation operation is not needed to be carried out based on a physical principle so as to realize the light emitting effect, so that the real light reflecting effect can be realized with only a small amount of calculation resources, the rendering speed is improved, and the rendering cost is reduced.

The method described in the previous examples is described in further detail below by way of example.

In this embodiment, a description will be given with reference to the system of fig. 1.

As shown in fig. 9, the specific flow of the method for implementing the light reflection effect in this embodiment may be as follows:

901. and obtaining a virtual object model with a reflection effect to be added, wherein the virtual object model comprises a transparent area and an image display area, and the transparent area is overlapped on the image display area.

Taking the virtual object model as a mirror, as shown in fig. 3, the structure of the whole mirror (i.e., the virtual object model) can be divided into three partial areas from back to front, which are respectively a decorative outer frame, a base map capable of showing a mirror looking effect in the mirror, and glass capable of making the surface of the mirror have a light reflecting effect, wherein the glass partial area is a transparent area, and the base map is an image display area.

902. And acquiring the smoothness, the preset reflective color and the light incidence direction corresponding to the transparent area.

903. Based on the smoothness, the reflection color and the light incidence direction, at least one reflection area displayed in the reflection color on a preset reflector model is calculated.

In the embodiment of the invention, a Blinn-Phong model can be used, and the position of a high light spot, namely a light reflection area, illuminated on the model is calculated through parameters set by us.

The normal information of the model is transferred from the model space to the world space, and the normal information is normalized and is marked as the normal direction. Specifically, the normalization processing, namely normal, can map the data to be processed within the range of-1 to 1, so that the calculation can be more convenient and faster.

And subtracting the coordinate of the model in world space from the coordinate of the camera, and carrying out normalization processing to obtain the sight direction of the camera looking at the model.

The normalization process is performed by adding the direction of the line of sight to the direction of illumination, and the normalization process is denoted as the half-way direction, i.e., half-way Vector (Halfway Vector).

The retroreflective area = retroreflective color x pow (max (0, dot (half way direction, normal direction)), smoothness) was calculated by Blinn-Phong model.

904. And obtaining a reflective texture map, wherein the reflective texture map comprises reflective effect textures.

Specifically, the retroreflective texture map may be as shown in fig. 5.

905. And fusing the light reflecting texture in the light reflecting texture map with the light reflecting area to obtain the treated light reflecting area with the light reflecting texture and the light reflecting color.

906. And determining a transparency adjustment channel from the color channels of the reflector model according to the reflective color, and adjusting the transparency parameter of the reflector model based on the color components of the reflector model in the transparency adjustment channel to obtain a treated reflective area of transparent treatment.

If the reflector pattern is black, the reflector pattern will block the effect behind the mirror. It is therefore desirable to have the reflector model exhibit the effect of having a certain transparency, for example, being transparent elsewhere than in the reflective portion.

Specifically, the color value has three channels of RGB, and we take a certain channel as a transparency adjustment channel to output the color value and the transparency.

907. And acquiring a target display image corresponding to the virtual object model, and displaying the target display image in the image display area so that the reflection effect in the transparent area is overlapped and displayed on the target display image.

908. And displaying the reflection effect on the transparent area on the virtual object model based on the processed reflection area.
