[0002] With the development of computer technology, the types of electronic games are becoming more and more diverse. In some electronic games, a virtual orthogonal camera is used to capture a virtual scene, and the captured virtual scene image is displayed.

For example, in a virtual scene image including multiple identical virtual chairs, no matter where the virtual chairs are located in the virtual scene image, the multiple virtual chairs are all displayed in the same size, resulting in a lack of layering in the virtual scene image and a poor display effect.

Optionally, the server is an independent physical server, or, is a server cluster or a distributed system composed of multiple physical servers, or, is a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0055] Figure 1It is a schematic structural diagram of an implementation environment provided by an embodiment of the present application. As Figure 1 shown, the system includes a terminal 101 and a server 102. The terminal 101 and the server 102 can be directly or indirectly connected through wired or wireless communication means, and the present application does not limit this here.

[0056] The server 102 provides virtual scene images for the terminal 101. The terminal 101 can display the virtual scene images provided by the server 102, and the terminal 101 can control the virtual scene. The server 102 is used to provide background support for the terminal 101 and can perform background processing according to the control of the virtual scene by the terminal 101.

[0057] Optionally, a game application is installed on the terminal 101, and the server 102 provides services for the game application. Through the game application, the terminal 101 and the server 102 can interact. The server 102 provides services for the terminal 101 so that the terminal 101 can display virtual scene images and can operate on the virtual scene images, such as controlling virtual objects to attack or move.

[0058] The method provided by the embodiment of the present application can be used in multiple scenarios.

[0059] For example, in a horizontal game scene:

[0060] A horizontal game application runs on a computer device. Through the horizontal game application running on the computer device, a two-dimensional virtual object in the virtual scene can be controlled to move left and right. When adjusting the field of view angle of the virtual camera in the horizontal game, the method provided by the embodiment of the present application is adopted to display the virtual scene image of the horizontal game, so that in the case where the virtual scene image presents the effect of near-big and far-small, and the two-dimensional virtual object is accurately displayed in the virtual scene image, both the three-dimensional effect presented by the virtual scene image is ensured, and the display position of the two-dimensional virtual object in the virtual scene image is accurate, thereby improving the display effect of the virtual scene.

[0061] Figure 2 It is a flowchart of a virtual scene display method provided by an embodiment of the present application, which is applied to a computer device. As Figure 2 shown, the method includes:

[0062] 201. The computer device displays a first virtual scene image.

[0063] Among them, the first virtual scene image includes two-dimensional virtual objects in the virtual scene. The first virtual scene image is obtained by a virtual camera shooting the virtual scene, and the image captured by the virtual camera shows the effect of objects being larger when closer and smaller when farther away. For example, in the virtual scene image, there are multiple identical two-dimensional virtual items. The two-dimensional virtual item closer to the virtual camera is displayed with a larger size, and the two-dimensional virtual item farther from the virtual camera is displayed with a smaller size.

[0064] 202. The computer device, in response to a change in the field of view angle of the virtual camera, obtains the 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.

[0065] Among them, the field of view angle of the virtual camera is used to indicate the range that the virtual camera can capture. The larger the field of view angle, the larger the captured range, and the smaller the field of view angle, 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 the display position of the two-dimensional virtual object in the second virtual scene image captured after the change in the field of view angle of the virtual camera.

[0066] Since the image captured by the virtual camera shows the effect of objects being larger when closer and smaller when farther away, when using this virtual camera to shoot the virtual scene, if the field of view angle of the virtual camera changes, it will cause the position of the two-dimensional virtual object in the virtual scene image to change, resulting in the display position of the two-dimensional virtual object in the virtual scene image being different from the position of the two-dimensional virtual object in the virtual scene. Therefore, when the field of view angle of the virtual camera changes, it is necessary to re-determine the second display position of the two-dimensional virtual object to ensure that the display position of the two-dimensional virtual object in the virtual scene image obtained after the change in the field of view angle is accurate.

[0067] 203. The computer device displays the second virtual scene image, and the two-dimensional virtual object is displayed at the second display position in the second virtual scene image.

[0068] In the embodiments of the present application, the position in the virtual scene corresponding to the first display position of the two-dimensional virtual object is the same as the position in the virtual scene corresponding to the second display position of the two-dimensional virtual object. By displaying the two-dimensional virtual object at the second display position in the second virtual scene image, the display position in the second virtual scene image corresponds to the position of the two-dimensional virtual object in the virtual scene, ensuring the accuracy of the display position of the two-dimensional virtual object.

[0069] The method provided by the embodiment of the present application corrects the display position of the two-dimensional virtual object in the virtual scene image when the field of view angle of the virtual camera changes, on the premise of ensuring that the virtual scene image presents the effect of objects being larger when closer and smaller when farther away. As a result, in the virtual scene image obtained after the change of the field of view angle, the two-dimensional virtual object is displayed according to the corrected display position, so that the virtual scene image presents a three-dimensional effect and can ensure the accurate display position of the two-dimensional virtual object, thereby improving the display effect of the virtual scene.

[0070] Figure 3 is a flowchart of a virtual scene display method provided by the embodiment of the present application, which is applied to a computer device, such as Figure 3 shown, the method includes:

[0071] 301. The computer device displays a first virtual scene image, and the first virtual scene image includes a two-dimensional virtual object in the virtual scene.

[0072] In the embodiment of the present application, the virtual camera is used to capture the virtual scene, so that the obtained virtual scene image presents a perspective effect, that is, the effect of objects being larger when closer and smaller when farther away, and the two-dimensional virtual object in the virtual scene image is corrected, and the two-dimensional virtual object itself does not produce a perspective effect. For example, the two-dimensional virtual object in the virtual scene image is displayed according to the scaling ratio of the position where it is located, so that the virtual scene image presents a perspective effect of objects being larger when closer and smaller when farther away, but the scaling ratios of different parts of the two-dimensional virtual object itself are equal, that is, the two-dimensional virtual object itself does not produce a perspective effect.

[0073] Optionally, the virtual camera is a virtual perspective camera. After the virtual perspective camera captures the virtual scene, the obtained virtual scene image presents a perspective effect, that is, the virtual scene image presents the effect of objects being larger when closer and smaller when farther away. In the embodiment of the present application, in the first virtual scene image, except for the two-dimensional virtual object, other parts of the virtual scene present the effect of objects being larger when closer and smaller when farther away, and the two-dimensional virtual object does not present a perspective effect.

[0074] The two-dimensional virtual object presents a two-dimensional display effect in the virtual scene image. Optionally, the two-dimensional virtual object is a virtual character, a virtual animal, etc. In a possible implementation manner, the two-dimensional virtual object corresponds to a three-dimensional virtual object in the virtual scene. Based on the virtual camera capturing the virtual scene, the captured virtual scene is rendered to obtain the first virtual scene image, so that the two-dimensional virtual object is presented in the first virtual scene image.

[0075] 302. The computer device responds to the change of the field of view angle of the virtual camera from the first field of view angle to the second field of view angle, and determines the field of view angle transformation matrix corresponding to the two-dimensional virtual object based on the first field of view angle and the second field of view angle.

[0076] Wherein, the first field of view angle is the field of view angle before the change of the virtual camera, and the second field of view angle is the field of view angle after the change of the virtual camera. The field of view angle transformation matrix is used to indicate the change of the field of view angle of the virtual camera. Through the first field of view angle and the second field of view angle, a field of view angle transformation matrix indicating the change of the field of view angle of the virtual camera is determined, so as to subsequently determine the display position of the two-dimensional virtual object according to the field of view angle transformation matrix.

[0077] In a possible implementation manner, step 302 includes: fusing the projection matrix of the first field of view angle and the projection matrix of the second field of view angle to obtain a field of view angle transformation matrix. Wherein, the projection matrix is used to indicate the matrix of the virtual scene captured by the virtual camera projected onto the virtual scene image, and the projection matrices corresponding to different fields of view angles are different, that is, the projection matrix of the first field of view angle is different from the projection matrix of the second field of view angle.

[0078] Optionally, the process of obtaining the field of view angle transformation matrix includes: determining the inverse matrix of the projection matrix of the first field of view angle, and determining the product between the projection matrix of the second field of view angle and the inverse matrix as the field of view angle transformation matrix.

[0079] Optionally, the projection matrix M of the first field of view angle x , the projection matrix M of the second field of view angle y and the field of view angle transformation matrix T view , satisfy the following relationship:

[0080]

[0081] Wherein, represents the inverse matrix of the projection matrix M of the first field of view angle x ; x represents the first field of view angle; y represents the second field of view angle.

[0082] 303. The computer device determines the target coordinates of the reference point of the two-dimensional virtual object in the first coordinate system based on the first field of view angle.

[0083] Wherein, the first coordinate system is the coordinate system of the virtual camera at the first field of view angle. 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.

[0084] Through the reference point of the two-dimensional virtual object and the first coordinate system of the virtual camera at the first field of view angle, the target coordinates of the reference point of the two-dimensional virtual object in the first coordinate system can be determined, so as to subsequently determine the display position of the two-dimensional virtual object after the change of the field of view angle of the virtual camera according to the target coordinates.

[0085] In a possible implementation, step 303 includes: obtaining 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.

[0086] Wherein, the second coordinate system is the coordinate system of the two-dimensional virtual object. The reference point of the two-dimensional virtual object has different coordinate values in different coordinate systems. The coordinate of the reference point in the second coordinate system is called the reference coordinate, and the coordinate of the reference point in the first coordinate system is called the target coordinate.

[0087] Optionally, the origin in the second coordinate system is the reference point of the two-dimensional virtual object. Then, perform coordinate system transformation on the coordinates of the origin in the second coordinate system to obtain the target coordinates of the origin in the first coordinate system.

[0088] Optionally, the coordinates of the origin in the second coordinate system and the target coordinates O of the origin in the first coordinate system view satisfy the following relationship:

[0089]

[0090] Wherein, T0 represents the transformation matrix from the second coordinate system of the two-dimensional virtual object to the first coordinate system of the virtual camera. For example, if the coordinates of the origin in the second coordinate system are (0, 0, 0), then the coordinate Wherein, 1 is an indication identifier for indicating that the first three elements in are coordinates.

[0091] 304. The computer device obtains the first offset matrix of the two-dimensional virtual object in the first coordinate system.

[0092] Wherein, the first offset matrix includes the offsets of multiple points of the two-dimensional virtual object from the reference point in the first coordinate system. In the embodiments of the present application, the two-dimensional virtual object is composed of multiple points. The offset between each point and the reference point represents the relative position between each point and the reference point. By determining the offsets between multiple points of the two-dimensional virtual object and the reference point of the two-dimensional virtual object, the relative positions between multiple points of the two-dimensional virtual object and the reference point are determined, that is, the relative position between the two-dimensional virtual object and the reference point is determined.

[0093] In a possible implementation, step 304 includes: obtaining the second offset matrix of the two-dimensional virtual object in the second coordinate system, and performing coordinate system transformation on the second offset matrix to obtain the first offset matrix.

[0094] Among them, the second coordinate system is the coordinate system of the two-dimensional virtual object, and the second offset matrix includes the offsets of multiple points of the two-dimensional virtual object and the reference point in the second coordinate system. For example, if the reference point of the two-dimensional virtual object is the origin of the second coordinate system, then in the second coordinate system, the offsets between multiple points of the two-dimensional virtual object and the origin constitute the second offset matrix to represent the relative position of the two-dimensional virtual object and the origin.

[0095] By determining the second offset matrix in the second coordinate system and converting the second offset matrix in the second coordinate system to the first coordinate system, the first offset matrix is obtained.

[0096] 305. The computer device determines the second display position based on the target coordinate, the first offset matrix, and the perspective transformation matrix.

[0097] Among them, the second display position is used to represent the display position of the two-dimensional virtual object in the virtual scene image after the field of view angle of the virtual camera changes.

[0098] After determining that the field of view angle of the virtual camera changes from the first field of view angle to the second field of view angle, since the target coordinate is the coordinate of the reference point of the two-dimensional virtual object in the first coordinate system, the first offset matrix can represent the relative positions of multiple points of the two-dimensional virtual object and the reference point in the first coordinate system, and the perspective transformation matrix indicates the change of the field of view angle of the virtual camera. Then, through the target coordinate, the first offset matrix, and the perspective transformation matrix, the second display position of the two-dimensional virtual object can be determined after the field of view angle of the virtual camera changes to the second field of view angle, so that the two-dimensional virtual object can be displayed at the second display position in the second virtual scene image subsequently.

[0099] In a possible implementation manner, the target coordinate O view , the first offset matrix V view , the field of view angle transformation matrix T view , and the second display position P" view satisfy the following relationship:

[0100]

[0101] Among them, x is used to represent the first field of view angle; y is used to represent the second field of view angle.

[0102] Optionally, if the reference point of the two-dimensional virtual object is the origin of the second coordinate system of the two-dimensional virtual object, then the first offset matrix V view satisfies the following relationship:

[0103] V view = (P local ·xyz, 0)·T0;

[0104] Among them, P localrepresents the origin of the two-dimensional virtual object in the second coordinate system; x, y, and z respectively represent the coordinate values of each point of the two-dimensional virtual object on the x-axis, y-axis, and z-axis in the second coordinate system; P local ·xyz represents the offset of each point of the two-dimensional virtual object from the origin of the second coordinate system in the second coordinate system; 0 is an indication identifier for indicating P local ·xyz is a vector; T0 represents the transformation matrix from the second coordinate system of the two-dimensional virtual object to the first coordinate system of the virtual camera.

[0105] It should be noted that in the embodiments of the present application, the target coordinates and the first offset matrix of the two-dimensional virtual object are used to determine the second display position of the two-dimensional virtual object for description. In another embodiment, steps 303-305 do not need to be executed, and other methods can be adopted to obtain the second display position of the two-dimensional virtual object based on the first display position and the field of view transformation matrix.

[0106] It should be noted that in the embodiments of the present application, the field of view transformation matrix corresponding to the virtual object is used to determine the second display position of the two-dimensional virtual object for description. In another embodiment, steps 302-305 do not need to be executed. In response to a change in the field of view of the virtual camera, other methods can be adopted to obtain the 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.

[0107] 306. The computer device displays the second virtual scene image, and a two-dimensional virtual object is displayed at the second display position in the second virtual scene image.

[0108] Among them, the second virtual scene image includes the virtual scene that the virtual camera can capture after the field of view changes and the two-dimensional virtual object located in the virtual scene, and the two-dimensional virtual object is displayed at the second display position to ensure that the display position of the two-dimensional virtual object is correct and corresponds to the position of the two-dimensional virtual object in the virtual scene. In the embodiments of the present application, if only the field of view of the virtual camera changes and the position of the virtual object in the virtual scene does not change, the display position of the two-dimensional virtual object in the virtual scene image may change, but the second display position of the two-dimensional virtual object is the same as the position corresponding to the first display position of the two-dimensional virtual object in the virtual scene.

[0109] In a possible implementation manner, before step 306, the method further includes: determining the position change amount between the second display position and the first display position, adjusting the position of the two-dimensional virtual object in the virtual scene according to the position change amount, and rendering the virtual scene captured by the virtual camera after the field of view changes to obtain the second virtual scene image.

[0110] Through the first display position and the second display position of the two-dimensional virtual object, the position change of the two-dimensional virtual object after the field of view angle of the virtual camera changes can be determined, and the display position of the two-dimensional virtual object is adjusted according to the position change to ensure that the display position of the two-dimensional virtual object in the displayed second virtual scene image is accurate.

[0111] In one possible implementation, step 306 includes: determining a fourth display position of the two-dimensional virtual object in the clipping coordinate system based on the second display position, and rendering the virtual scene captured by the virtual camera at the second field of view angle based on the fourth display position to obtain the second virtual scene image, so that the two-dimensional virtual object is displayed at the third display position in the second virtual scene image.

[0122] It should be noted that the embodiments of the present application are only described by determining the position of the two-dimensional virtual object after the field of view angle of the virtual camera changes. In response to the virtual scene including two-dimensional virtual items, determining the position in the virtual scene image is similar to the process of determining the two-dimensional virtual object, which will not be elaborated here.

[0123] In addition, the above embodiments are only described by determining the position of the two-dimensional virtual object after the field of view angle of the virtual camera changes. In another embodiment, if the virtual object in the virtual scene holds a two-dimensional virtual item, then after step 302, the method further includes the following steps 307-310:

[0124] 307. The computer device obtains the target offset of the reference point of the two-dimensional virtual object and the reference point of the two-dimensional virtual item in the first coordinate system.

[0125] In the embodiments of the present application, since the two-dimensional virtual object holds the two-dimensional virtual item, therefore, in order to ensure that the positions of the two-dimensional virtual item and the two-dimensional virtual object are accurately displayed after the field of view angle of the virtual camera changes, therefore, the relative display position between the two-dimensional virtual item and the two-dimensional virtual object is used to determine the display position of the two-dimensional virtual item to ensure the accurate display position of the two-dimensional virtual item in the virtual scene image with the change of the field of view angle of the virtual camera.

[0126] Among them, the reference point of the two-dimensional virtual item is any point of the two-dimensional virtual item. Optionally, the reference point of the two-dimensional virtual item is the origin of the third coordinate system of the two-dimensional virtual item. The target offset is used to represent the offset vector between the reference point of the two-dimensional virtual object and the reference point of the two-dimensional virtual item in the first coordinate system. Optionally, the target offset is represented by a vector.

[0127] In a possible implementation, step 307 includes: obtaining the reference offset between the reference point of the two-dimensional virtual object and the reference point of the two-dimensional virtual item in the third coordinate system, and performing coordinate system transformation on the reference offset to obtain the target offset.

[0128] Among them, the third coordinate system is the coordinate system of the two-dimensional virtual item. The reference offset is used to indicate the offset between the reference point of the two-dimensional virtual object and the reference point of the two-dimensional virtual item in the third coordinate system. Optionally, the reference offset is represented in the form of a vector. After determining the reference offset in the third coordinate system, the target offset is obtained by converting the reference offset in the third coordinate system to the first coordinate system.

[0129] Optionally, determine the first coordinate of the reference point of the two-dimensional virtual object in the third coordinate system and the second coordinate of the reference point of the two-dimensional virtual object in the third coordinate system, and determine the reference offset by taking the difference between the first coordinate and the second coordinate.

[0130] 308. The computer device obtains the third offset matrix of the two-dimensional virtual item in the first coordinate system.

[0131] Among them, the third offset matrix includes the offsets between multiple points of the two-dimensional virtual item and the reference point of the two-dimensional virtual object in the first coordinate system. In the embodiments of the present application, the two-dimensional virtual item is composed of multiple points. The offset between each point and the reference point represents the relative position between each point and the reference point. By determining the offsets between multiple points of the two-dimensional virtual item and the reference point of the two-dimensional virtual item, the relative positions between multiple points of the two-dimensional virtual item and the reference point can be determined, and thus the relative position between the two-dimensional virtual item and the reference point can be determined.

[0132] In a possible implementation, step 308 includes: obtaining the fourth offset matrix of the two-dimensional virtual item in the third coordinate system, and performing coordinate system transformation on the fourth offset matrix to obtain the third offset matrix.

[0133] Among them, the third coordinate system is the coordinate system of the two-dimensional virtual item, and the fourth offset matrix includes the offsets of multiple points of the two-dimensional virtual item and the reference point of the two-dimensional virtual object in the third coordinate system. For example, if the reference point of the two-dimensional virtual item is the origin of the third coordinate system, then in the third coordinate system, the offsets between multiple points of the two-dimensional virtual item and the origin constitute the third offset matrix to represent the relative position of the two-dimensional virtual item and the origin.

[0134] In the third coordinate system, by determining the offset between each point of the two-dimensional virtual item and the reference point of the two-dimensional virtual item, the fourth offset matrix can be obtained. By transforming the fourth offset matrix, the fourth offset matrix is transformed to the first coordinate system to obtain the third offset matrix.

[0135] Optionally, obtain the fifth offset matrix of the two-dimensional virtual item in the third coordinate system, obtain the reference offset between the reference point of the two-dimensional virtual object and the reference point of the two-dimensional virtual item in the third coordinate system, and determine the fourth offset matrix based on the fifth offset matrix and the reference offset. Among them, the fifth offset matrix includes the offsets of multiple points of the two-dimensional virtual item and the reference point of the two-dimensional virtual item in the third coordinate system.

[0136] Optionally, determine the difference between the fifth offset matrix and the reference offset as the fourth offset matrix.

[0137] 309. The computer device determines the third display position based on the target offset, the third offset matrix, and the perspective transformation matrix.

[0138] Among them, the third display position is used to represent the display position of the two-dimensional virtual item in the virtual scene image after the field of view angle of the virtual camera changes.

[0139] After determining the target offset, the third offset matrix, and the perspective transformation matrix of the two-dimensional virtual item, the position of the two-dimensional virtual item in the virtual scene image and the third display position can be determined after the field of view angle of the virtual camera changes.

[0140] After determining that the field of view angle of the virtual camera changes from the first field of view angle to the second field of view angle, since the target offset is the offset vector between the reference point of the two-dimensional virtual object and the reference point of the two-dimensional virtual item in the first coordinate system, the third offset matrix can represent the relative position of multiple points of the two-dimensional virtual item and the reference point of the two-dimensional virtual object in the first coordinate system, and the perspective transformation matrix indicates the change of the field of view angle of the virtual camera. Then, through the target offset, the third offset matrix, and the perspective transformation matrix, the third display position of the two-dimensional virtual item can be determined after the field of view angle of the virtual camera changes to the second field of view angle, so that the two-dimensional virtual item can be displayed at the third display position of the second virtual scene image subsequently.

[0141] In a possible implementation, the target offset Q view , the third offset matrix the field of view transformation matrix T view and the third display position P″′ view , satisfy the following relationship:

[0142]

[0143] where x is used to represent the first field of view angle; y is used to represent the second field of view angle.

[0144] It should be noted that in the embodiments of this application, the third display position of the two-dimensional virtual item is determined based on the target offset and the third offset matrix of the two-dimensional virtual item. In another embodiment, steps 307-309 do not need to be executed, and other methods can be adopted to obtain the third display position of the two-dimensional virtual item based on the relative display position and the field of view transformation matrix.

[0145] It should be noted that in the embodiments of this application, the third display position of the two-dimensional virtual item is determined based on the field of view transformation matrix corresponding to the virtual object. In another embodiment, steps 302, 307-309 do not need to be executed, and other methods can be adopted to obtain the third display position of the two-dimensional virtual item based on the relative display position between the two-dimensional virtual item and the two-dimensional virtual object in the first virtual scene image.

[0146] 310. The computer device displays the two-dimensional virtual item at the third display position in the second virtual scene image.

[0147] After determining the third display position of the two-dimensional virtual item in the second virtual scene image, the two-dimensional virtual item is displayed at the third display position to ensure that the position of the two-dimensional virtual item is accurately displayed after the field of view angle of the virtual camera changes.

[0148] It should be noted that the embodiments of this application only describe the two-dimensional virtual item held by the two-dimensional virtual object. In another embodiment, if the two-dimensional virtual item includes two-dimensional sub-virtual items, the display position of the two-dimensional sub-virtual item is determined by determining the relationship between the two-dimensional sub-virtual item and the two-dimensional virtual object to which it belongs, and then the two-dimensional sub-virtual item is displayed in the second scene image.

[0149] The method provided by the embodiments of this application can make the displayed virtual scene reflect a three-dimensional virtual effect, and the two-dimensional virtual object does not deform, thus ensuring the display effect of the virtual scene.

[0150] In the embodiments of the present application, the virtual scene includes three-dimensional virtual objects. The virtual scene is rendered by a three-dimensional virtual camera, so that the virtual scene presents a three-dimensional display effect, and the three-dimensional virtual objects are rendered to obtain two-dimensional virtual objects corresponding to the three-dimensional virtual objects, so that the display effect of the two-dimensional virtual objects presented in the virtual scene image is the same as that rendered by an orthographic camera, and the display position of the two-dimensional virtual objects is corrected to ensure that the display position of the two-dimensional virtual objects in the virtual scene image is the same as the position of the three-dimensional virtual objects in the three-dimensional virtual scene.

[0151] The method provided by the embodiments of the present application corrects the display position of the two-dimensional virtual objects in the virtual scene image when the field of view angle of the virtual camera changes, on the premise of ensuring that the virtual scene image presents the effect of near-big and far-small. So that in the virtual scene image obtained after the change of the field of view angle, the two-dimensional virtual objects are displayed according to the corrected display position, and the virtual scene image not only presents a three-dimensional effect, but also ensures the accurate display position of the two-dimensional virtual objects, thereby improving the display effect of the virtual scene.

[0152] Moreover, when the two-dimensional virtual object holds a virtual item, the display position of the two-dimensional virtual object in the virtual scene image obtained after the change of the field of view angle is determined by the relative display position of the two-dimensional virtual item and the two-dimensional virtual object in the first virtual scene image, ensuring the fitting of the display positions of the two-dimensional virtual object and the two-dimensional virtual item in the virtual scene image, and improving the display effect of the virtual scene.

[0153] Based on the method provided in the above embodiments, after the field of view angle of the virtual camera changes, for example, the first field of view angle of the virtual camera is 5 degrees and the second field of view angle is 90 degrees. If directly based on the first field of view angle and the second field of view angle of the virtual camera to determine any position P view The position P' of P in the coordinate system of the second field of view angle view , then the position P view , the position P' view Satisfy the following relationship:

[0154]

[0155] Among them, P view Is used to represent the position in the coordinate system before the change of the field of view angle of the virtual camera, P' view Is used to represent the position in the coordinate system after the change of the field of view angle of the virtual camera, and M5 is used to represent the projection matrix with a changed field of view angle of 5, Is used to represent the inverse matrix of the projection matrix with a changed field of view angle of 90.

[0156] Through the above relationship, the position Pv iewThe position P' in the coordinate system converted to the second field of view angle view After that, according to the position P' view Display the virtual scene image of the two-dimensional virtual object, such as Figure 4 As shown, in the case where the image captured by the virtual camera presents the effect of objects being larger when closer and smaller when farther away, if the field of view angle of the virtual camera changes, the display position of the virtual object in the virtual scene image will shift, resulting in inaccurate display position of the two-dimensional virtual object in the virtual scene image. Therefore, in order to ensure the accurate display position of the two-dimensional virtual object in the virtual scene image, based on the method provided in the above embodiment, determine the display position of the two-dimensional virtual object after the change of the field of view angle of the virtual camera, so that the two-dimensional virtual object in the virtual scene image is displayed according to the determined display position, as Figure 5 Shown to ensure the accurate display position of the two-dimensional virtual object.

[0157] Based on the virtual scene display method provided in the above embodiment, the computer device includes a CPU (Central Processing Unit, central processor), a Constant Buffer (constant buffer), and a vertex shader.

[0158] The CPU obtains the first field of view angle and the second field of view angle before and after the change of the virtual camera, and determines the field of view angle transformation matrix T view According to the values of the parameters in, and send the vector To the Constant Buffer for use by the vertex shader.

[0159] In the 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 angle of the virtual camera changes, for the vertex shader of the two-dimensional virtual object, obtain the vector from the Constant Buffer, and determine the field of view angle transformation matrix T view , and execute the above steps 303-305 to determine the second display position of the two-dimensional virtual object. For the vertex shader of the two-dimensional virtual item, obtain the vector from the Constant Buffer, and determine the field of view angle transformation matrix T view , and execute the above steps 307-309 to determine the third display position of the two-dimensional virtual item.

[0160] In addition, when determining the third display position of the two-dimensional virtual item, the CPU calls the GetParentRelativeLocation function to determine the parent object to which the two-dimensional virtual item belongs. In response to the parent object being a virtual object, the coordinates of the two-dimensional virtual object relative to the two-dimensional virtual item are determined, thereby determining the target offset of the two-dimensional virtual item relative to the two-dimensional virtual object, so as to subsequently determine the third display position of the two-dimensional virtual item through the vertex shader of the two-dimensional virtual item.

[0161] In addition, based on the method provided in the above embodiment, if there are two-dimensional virtual items in the virtual scene and the two-dimensional virtual items are not held by the two-dimensional virtual object, when determining the display position of the two-dimensional virtual item, it is similar to the method for determining the display position of the two-dimensional virtual object described above; if there are two-dimensional virtual items in the virtual scene and the two-dimensional virtual object holds the two-dimensional virtual item, when determining the display position of the two-dimensional virtual item, the display position of the two-dimensional virtual item held by the two-dimensional virtual object is determined according to the above method. Since the two-dimensional virtual object in the virtual scene may pick up the virtual item in the virtual scene, or the two-dimensional virtual object may discard the two-dimensional virtual item it holds, in order to avoid the jump of the displayed virtual scene image at the moment when the two-dimensional virtual object picks up or discards the two-dimensional virtual item, therefore, a dimension is added to the target offset, and the value of this dimension is used to represent a switch value. The CPU gradually sets the switch value of the target offset. For example, the switch values include 2 and 3. 2 indicates that the coordinate value is the coordinate value under the two-dimensional virtual item, and 3 indicates the value of the reference point of the two-dimensional virtual object in the coordinate system of the two-dimensional virtual item. Then, by setting the switch value to 2.1, 2.3, 2.5, 2.7, 2.9, the two-dimensional virtual object displayed in the virtual scene image does not jump when picking up or discarding the two-dimensional virtual item, thus ensuring the display effect of the virtual scene.

[0162] In addition, based on the method provided in the embodiments 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, so that the virtual scene image can present an orthogonal display effect and display the virtual scene in the manner of a landscape scene.

[0163] In addition, the method provided in the embodiments of the present application can be applied to both landscape games and top-down view IO games, and can improve the display effect of the virtual scene.

[0164] Such as Figure 6As shown, based on the method provided in the above embodiments, the virtual objects displayed in the virtual scene image all present the effect of being larger in the distance and smaller up close, that is, the virtual scene image presents a perspective effect. After the field of view angle 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. Through the method provided in the embodiments of the present application, the display position of the cube 602 in the virtual scene image after the field of view angle of the virtual camera changes is determined, and the cube 602 is displayed 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.

[0165] Figure 7 and Figure 8 are all schematic diagrams of the virtual scene image. As Figure 7 shown, the two-dimensional virtual object 701 and the two-dimensional virtual object 702 have the same distance from the virtual camera. Then, compared with the two-dimensional virtual object 701 and the two-dimensional virtual object 702, the two-dimensional virtual object 701 and the two-dimensional virtual object 702 do not deform themselves, that is, neither the two-dimensional virtual object 701 nor the two-dimensional virtual object 702 produces a perspective effect. As Figure 8 shown, the sizes of the two-dimensional virtual objects at different positions in the virtual scene image may be different. That is, the two-dimensional virtual object 801 is close to the virtual camera, and the two-dimensional virtual object 802 is far from the virtual camera. Then, in the second virtual scene image, the two-dimensional virtual object 801 has a large display size, and the two-dimensional virtual object 802 has a small display size. Moreover, based on the method provided in the embodiments of the present application, the virtual camera can freely move the lens. For example, the position of the virtual camera changes, or the virtual camera rotates the shooting angle, so that different scene images can be presented in the virtual scene image, and the virtual scene can show a three-dimensional display effect. As Figure 8 shown, the virtual scene image presents the back of the two-dimensional virtual object, and ensures that the virtual scene image presents the effect of being larger in the near and smaller in the distance, and the two-dimensional virtual object itself does not produce a perspective effect.

[0166] Based on the method provided in the embodiments of the present application, the free switching between the landscape rendering mode and the three-dimensional rendering mode can be realized. Figure 9 is a virtual scene image in a three-dimensional scene. As Figure 9 shown, the virtual object 701 and the virtual object 702 belong to the same virtual object. By performing lens movement processing on the virtual object, the virtual object 702 rotates relative to the virtual object 701 by an angle, so that the virtual object itself can present a three-dimensional effect display. Through the method provided in the embodiments of the present application, both the display effect of landscape rendering and the three-dimensional rendering mode can be realized, and flexible switching between multiple rendering schemes can be performed, ensuring the flexibility of virtual scene display.
