2 is a flowchart of a method for displaying a virtual scene provided by an embodiment of the present application, which is applied to a computer device. As shown in FIG. 2 , the method includes:

201. The computer device displays a first virtual scene image.

The first virtual scene image includes two-dimensional virtual objects in the virtual scene, the first virtual scene image is obtained by photographing the virtual scene by a virtual camera, and the image photographed by the virtual camera presents the effect of being near and far. For example, a virtual scene image includes multiple identical 2D virtual items, the 2D virtual items that are close to the virtual camera are displayed in a larger size, and the 2D virtual items that are far away from the virtual camera are displayed in small sizes.

202. The computer device acquires a second display position of the two-dimensional virtual object based on the first display position of the two-dimensional virtual object in the first virtual scene image in response to the change in the field of view of the virtual camera.

The field of view of the virtual camera is used to indicate the range that the virtual camera can capture. The larger the field of view, the larger the captured range, and the smaller the field of view, the smaller the captured range. The first display position is used to indicate the position of the two-dimensional virtual object in the first virtual scene image, and the second display position is used to indicate that in the second virtual scene image captured by the virtual camera after the angle of view changes, the two-dimensional The display position of the virtual object.

Since the image captured by the virtual camera presents the effect of being near big and far small, when the virtual camera is used to shoot a virtual scene, if the field of view of the virtual camera is changed, it will cause the two-dimensional virtual object in the virtual scene image to be blurred. The position changes, so that the display position of the two-dimensional virtual object in the virtual scene image is different from the position of the two-dimensional virtual object in the virtual scene. Therefore, when the field of view of the virtual camera changes, it is necessary to re-determine two The second display position of the two-dimensional virtual object is ensured in the virtual scene image obtained after the angle of view is changed, and the display position of the two-dimensional virtual object is accurate.

203. The computer device displays a second virtual scene image, and a two-dimensional virtual object is displayed on a second display position in the second virtual scene image.

In the embodiment of the present application, the position corresponding to the first display position of the two-dimensional virtual object in the virtual scene is the same as the position corresponding to the second display position of the two-dimensional virtual object in the virtual scene. By displaying the two-dimensional virtual object at the second display position in the second virtual scene image, so that the display position in the second virtual scene image corresponds to the position of the two-dimensional virtual object in the virtual scene, the The display position of 2D virtual objects is accurate.

For example, the two-dimensional virtual object in the virtual scene image is displayed according to the zoom ratio of its position, so that the virtual scene image presents a perspective effect of near, large and far, but the zoom ratio of different parts of the two-dimensional virtual object is equal, that is The two-dimensional virtual object itself does not produce the effect of perspective.

Optionally, the virtual camera is a virtual perspective camera. After the virtual scene is photographed by the virtual perspective camera, the obtained virtual scene image presents a perspective effect, that is, the virtual scene image presents the effect of being large near and far and small.

In response to the change of the field of view of the virtual camera from the first angle of view to the second angle of view, the computer device determines the conversion of the field of view corresponding to the two-dimensional virtual object based on the first angle of view and the second angle of view matrix.

The first angle of view is the angle of view before the virtual camera is changed, and the second angle of view is the angle of view after the change of the virtual camera. The field of view transformation matrix is used to indicate the change of the field of view of the virtual camera. Through the first angle of view and the second angle of view, a view angle transformation matrix indicating the change of the view angle of the virtual camera is determined, so that the display position of the two-dimensional virtual object can be subsequently determined according to the view angle transformation matrix.

In a possible implementation manner, the step 302 includes: fusing the projection matrix of the first field of view with the projection matrix of the second field of view to obtain a conversion matrix of the field of view.

The reference point of the two-dimensional virtual object is any point of the two-dimensional virtual object. Optionally, the reference point of the two-dimensional virtual object is the origin in the second coordinate system of the two-dimensional virtual object.

Through the reference point of the two-dimensional virtual object and the first coordinate system of the virtual camera under the first field of view, the target coordinates of the reference point of the two-dimensional virtual object in the first coordinate system can be determined, so as to facilitate subsequent The target coordinates determine the display position of the two-dimensional virtual object after the viewing angle of the virtual camera is changed.

In a possible implementation manner, the step 303 includes: acquiring the reference coordinates of the reference point of the two-dimensional virtual object in the second coordinate system, and performing coordinate system transformation on the reference coordinates to obtain the target coordinates.

The second coordinate system is the coordinate system of the two-dimensional virtual object, and the reference point of the two-dimensional virtual object has different coordinate values in different coordinate systems, and the coordinates of the reference point in the second coordinate system are called Reference coordinates, the coordinates of the reference point in the first coordinate system are called target coordinates.

For example, the coordinates of the origin in the second coordinate system are (0, 0, 0), then the coordinates O" _view = (0, 0, 0, 1), where 1 is an indicator for indicating the coordinate O" The first three elements in the _view are coordinates.

304. The computer device acquires a first offset matrix of the two-dimensional virtual object in the first coordinate system.

Wherein, the first offset matrix includes offsets between the multiple points of the two-dimensional virtual object and the reference point in the first coordinate system. In the embodiment of the present application, the two-dimensional virtual object is composed of multiple points, and the offset between each point and the reference point represents the relative position between each point and the reference point. By determining the two-dimensional virtual object The offset between the multiple points of the object and the reference point of the two-dimensional virtual object, that is, the relative position between the multiple points of the two-dimensional virtual object and the reference point is determined, that is, the two-dimensional virtual object is determined.

After determining the third display position of the two-dimensional virtual item in the second virtual scene image, display the two-dimensional virtual item on the third display position to ensure that after the field of view of the virtual camera changes, the two-dimensional virtual item's The location is displayed accurately.

It should be noted that the embodiments of the present application are only described with a two-dimensional virtual item held by a two-dimensional virtual object. In another embodiment, the two-dimensional virtual item includes a two-dimensional sub-virtual The relationship between the two-dimensional sub-virtual item and the two-dimensional virtual object to which it belongs determines the display position of the two-dimensional sub-virtual item, and then displays the two-dimensional sub-virtual item in the second scene image.

The method provided by the embodiment of the present application can enable the displayed virtual scene to reflect a three-dimensional virtual effect, and the two-dimensional virtual object is not deformed, thereby ensuring the display effect of the virtual scene.

In the embodiment of the present application, the virtual scene includes a 3D virtual object, the virtual scene is rendered by a 3D virtual camera, so that the virtual scene presents a 3D display effect, and the 3D virtual object is rendered to obtain a 2D corresponding to the 3D virtual object. Virtual object, so that the display effect of the two-dimensional virtual object presented in the virtual scene image is the same as the display effect rendered by the orthogonal camera, and the display position of the two-dimensional virtual object is corrected to ensure the two-dimensional virtual object in the virtual scene image. The display position of the object is the same as the position of the 3D virtual object in the 3D virtual scene.

The method provided by the embodiment of the present application, on the premise of ensuring that the virtual scene image presents the effect of large near and far small, when the field of view of the virtual camera changes, the display position of the two-dimensional virtual object in the virtual scene image is corrected , so that the two-dimensional virtual object is displayed according to the corrected display position in the virtual scene image obtained after the change of the field of view. The virtual scene image not only presents the three-dimensional effect, but also ensures the accurate display position of the two-dimensional virtual object, thereby improving The display effect of the virtual scene.

In addition, when the two-dimensional virtual object holds the virtual object, the relative display position of the two-dimensional virtual object and the two-dimensional virtual object in the first virtual scene image is used to determine the virtual scene obtained by the two-dimensional virtual object after the angle of view changes. The display position in the image ensures that the display positions of the two-dimensional virtual object and the two-dimensional virtual item in the virtual scene image fit together, which improves the display effect of the virtual scene.

Based on the method provided by the above embodiment, after the field of view of the virtual camera changes, for example, the first field of view of the virtual camera is 5 degrees, and the second field of view is 90 degrees. The angle of view and the second angle of view are used to determine the position P' view of any position P _view in the coordinate system of the second angle of _view , then the position P _view and the position P' _view satisfy the following relationship:

用于表示变化后的视场角为90的投影矩阵的逆矩阵。Among them, P _view is used to represent the position in the coordinate system before the angle of view of the virtual camera is changed, P' _view is used to represent the position in the coordinate system after the angle of view of the virtual camera is changed, and M ₅ is used to represent The projection matrix of the changed field of view is 5,

The inverse of the projection matrix used to represent the changed field of view of 90.

Through the above relationship, after the position P _view is converted into the position P' _view in the coordinate system of the second field of view, the virtual scene image of the two-dimensional virtual object is displayed according to the position P' _view , as shown in Fig. 4, in the virtual camera In the case where the captured image presents the effect of being near big and far small, if the field of view of the virtual camera changes, the display position of the virtual object in the virtual scene image is shifted, resulting in a two-dimensional virtual scene in the virtual scene image. Objects are displayed in inaccurate positions. Therefore, in order to ensure that the display position of the two-dimensional virtual object in the virtual scene image is accurate, based on the method provided by the above embodiment, the display position of the two-dimensional virtual object after the field angle of the virtual camera is changed is determined, so that the virtual scene image The middle two-dimensional virtual object is displayed according to the determined display position, as shown in FIG. 5 , so as to ensure that the display position of the two-dimensional virtual object is accurate.

Sent to the Constant Buffer for use by the vertex shader.

In this embodiment of the present application, both the two-dimensional virtual object and the two-dimensional virtual item have corresponding vertex shaders. After the field of view of the virtual camera changes, for the vertex shader of the two-dimensional virtual object, a vector is obtained from ConstantBuffer to determine The viewing angle transformation matrix T _view is obtained, and the above steps 303-305 are executed to determine the second display position of the two-dimensional virtual object. For the vertex shader of the 2D virtual item, obtain the vector from the Constant Buffer, determine the field angle transformation matrix T _view , and execute the above steps 307-309 to determine the third display position of the 2D virtual item.

In addition, when the third display position of the two-dimensional virtual item is determined, the function of GetParentRelativeLocation (obtaining the relative coordinates of the parent object) is called by the CPU to determine the parent object to which the two-dimensional virtual item belongs. The coordinates of the two-dimensional virtual object relative to the two-dimensional virtual object, so as to determine the target offset of the two-dimensional virtual object relative to the two-dimensional virtual object, so that the vertex shader of the two-dimensional virtual object can be used to determine the position of the two-dimensional virtual object.

In addition, based on the method provided by the above embodiment, if the virtual scene includes a two-dimensional virtual item, and the two-dimensional virtual item is not held by the two-dimensional virtual object, then when determining the display position of the two-dimensional virtual item, it is the same as the above-mentioned determination two. The method for displaying the position of the 2D virtual object is similar; if a 2D virtual item is included in the virtual scene, and the 2D virtual object holds the 2D virtual item, then when determining the display position of the 2D virtual item, the 2D virtual item is determined as described above. The display position of the 2D virtual item held by the virtual object. Since the 2D virtual object in the virtual scene may pick up the virtual item in the virtual scene, or the 2D virtual object may discard the 2D virtual item held in hand, in order to avoid the moment when the 2D virtual object picks up or discards the 2D virtual item , the displayed virtual scene image jumps. Therefore, a dimension is added to the target offset, and the value of this dimension is used to represent the switch value. The CPU performs gradient settings on the switch value of the target offset. For example, the switch value includes 2 and 3, 2 indicates that the coordinate value is the coordinate value under the two-dimensional virtual object, and 3 indicates the value of the reference point of the two-dimensional virtual object under the coordinate system of the two-dimensional virtual object, then by setting the switch value from 2.1, 2.3, 2.5, 2.7, 2.9, so that when the two-dimensional virtual object displayed in the virtual scene image picks up or discards the two-dimensional virtual item, the display of the virtual scene image does not jump, thereby ensuring the display effect of the virtual scene.

In addition, based on the method provided by the embodiment of the present application, the target coordinates of the two-dimensional virtual object and the coordinates of the reference point of the two-dimensional virtual item are both set to fixed values in the coordinate system of the virtual camera, then the virtual scene image can present an orthogonal image The display effect is displayed, and the virtual scene is displayed in the way of horizontal scene.

In addition, the method provided by the embodiment of the present application can be applied to both a horizontal game and an IO game from a top-down perspective, both of which can improve the display effect of the virtual scene.

As shown in FIG. 6 , based on the method provided in the above-mentioned embodiment, the virtual objects displayed in the virtual scene image all present the effect of being far and near, that is, the virtual scene image presents the effect of perspective. After the field of view of the virtual camera changes, the cube 601 in the virtual scene image will be deformed, that is, the cube 601 presents a perspective effect, and the method provided by the embodiment of the present application is used to determine the change of the field of view of the cube 602 in the virtual camera. and display the cube 602 in the virtual scene image according to the determined display position, that is, the cube 602 is not deformed, and the perspective effect of the cube is corrected, so that the display position of the cube 602 is accurate .

As shown in FIG. 8 , the size of the two-dimensional virtual objects at different positions in the virtual scene image may be too small, that is, the distance between the two-dimensional virtual object 801 and the virtual camera is short, and the distance between the two-dimensional virtual object 802 and the virtual camera is far, then In the second virtual scene image, the display size of the two-dimensional virtual object 801 is large, and the display size of the two-dimensional virtual object 802 is small.

FIG. 9 is a virtual scene image in a 3D scene. As shown in FIG. 9 , the virtual object 701 and the virtual object 702 belong to For the same virtual object, by performing mirror motion processing on the virtual object, the virtual object 702 is rotated relative to the virtual object 701 by an angle, so that the virtual object itself can present a three-dimensional effect display.
