Description

Technical Field

[0001] This disclosure relates to the field of computer vision technology, and more specifically, to a method, apparatus, and storage medium for adjusting the display form of virtual game characters. Background Technology

[0002] Wide-angle lenses are frequently used in anime to enhance visual effects. Due to their short focal length and wide angle of view, wide-angle lenses can capture a large area of ​​scenery within a relatively short shooting distance. Games using anime characters can employ similar techniques to recreate the charm of the work, providing players with a better gaming experience. However, in reality, virtual game characters in wide-angle shots distort due to the stretching of three-dimensional space. Adjusting the field of view also alters the composition of the image, making it difficult to maintain a good display of the virtual game characters and thus negatively impacting the player's visual experience.

[0003] There is currently no effective solution to the above problems. Summary of the Invention

[0004] This disclosure provides at least some embodiments of a method, apparatus, and storage medium for adjusting the display form of virtual game characters, in order to at least solve the technical problem that the poor visual experience of game players is caused by the deformation of virtual game characters in wide-angle images as they change with three-dimensional space.

[0005] According to one embodiment of this disclosure, a method for adjusting the display form of a virtual game character is provided, comprising: obtaining the shooting position and shooting field of view of at least one virtual camera in a game scene, wherein the shooting field of view is used to determine the field of view range of at least one virtual camera at the shooting position; determining the initial form of at least one virtual game character in the game scene screen corresponding to the shooting field of view; and performing axial compression zoom adjustment on the initial form based on the shooting field of view to obtain the target display form of at least one virtual game character, wherein the axial compression zoom adjustment is used to determine the compression zoom direction corresponding to at least one virtual game character through the change of the field of view, and to perform compression zoom on the initial form according to the compression zoom direction to adjust the display form of at least one virtual game character.

[0006] According to one embodiment of this disclosure, an apparatus for adjusting the display form of a virtual game character is also provided, comprising: an acquisition module for acquiring the shooting position and shooting field of view of at least one virtual camera in a game scene, wherein the shooting field of view is used to determine the field of view of at least one virtual camera at the shooting position; a determination module for determining the initial form of at least one virtual game character in the game scene image corresponding to the shooting field of view; and an adjustment module for performing axial compression zoom adjustment on the initial form based on the shooting field of view to obtain the target display form of at least one virtual game character, wherein the axial compression zoom adjustment is used to determine the compression zoom direction corresponding to at least one virtual game character through the change of the field of view, and to perform compression zoom on the initial form according to the compression zoom direction to adjust the display form of at least one virtual game character.

[0007] According to one embodiment of the present disclosure, a computer-readable storage medium is also provided, which stores a computer program, wherein the computer program is configured to execute the method of adjusting the display form of a virtual game character as described above when it is run.

[0008] According to one embodiment of this disclosure, an electronic device is also provided, including a memory and a processor, wherein the memory stores a computer program and the processor is configured to run the computer program to perform the method of adjusting the display form of a virtual game character as described above.

[0009] In at least some embodiments of this disclosure, by obtaining the shooting position and shooting field of view of at least one virtual camera in the game scene, the initial form of at least one virtual game character in the game scene corresponding to the shooting field of view is determined. Finally, the initial form is axially compressed and zoomed based on the shooting field of view to obtain the target display form of at least one virtual game character. This achieves the purpose of flexibly adjusting the display form of the virtual game character based on the shooting position and shooting field of view of the virtual camera, thereby achieving the technical effect of maintaining a good display form of the virtual game character in the wide-angle image and improving the visual experience of the game player. This solves the technical problem that the virtual game character in the wide-angle image will deform with the three-dimensional space, resulting in a poor visual experience for the game player.

[0024] To enable those skilled in the art to better understand the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present disclosure.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] First, some nouns or terms that appear in the description of the embodiments of this application shall be interpreted as follows:

[0027] Wide-angle lens: Also known as a short-angle lens, it is a type of auxiliary lens for photography. Images shot with a wide-angle lens can highlight the central subject and foreground while also featuring a wide background. Therefore, it allows you to capture more scenery in a relatively small environment. At the same shooting distance, the scene captured with a wide-angle lens will appear smaller than that captured with a standard lens. When shooting close-up objects, it will produce perspective distortion and increase the perceived distance between foreground and background objects.

[0028] Animation intellectual property (IP): Animation IP refers to the intellectual property rights of animation characters.

[0029] Game engine: A game engine is a pre-written, editable computer game system or the core component of an interactive real-time graphics application. These systems provide game designers with a variety of tools needed to write games, with the aim of enabling game designers to easily and quickly create game programs without starting from scratch.

[0030] Field of view (FOV): In optical engineering, the field of view is also called the field of view. The size of the field of view determines the field of view range of an optical instrument.

[0031] Hitchcock zoom: Also known as dolly zoom, Hitchcock zoom is a common lens technique in film and television shooting. The characteristic of Hitchcock zoom is that the size of the subject in the lens remains unchanged, while the size of the background changes.

[0032] In related technologies, to maintain the original composition in front of a wide-angle lens that is constantly adjusting its focus, the traditional wide-angle adjustment shooting technique, in real-world film and television shooting, uses Hitchcock zoom. Figure 1 This is a schematic diagram of a sliding zoom technique in related technologies, such as... Figure 1 As shown, by using a sliding zoom method, the camera's field of view is adjusted from field of view 1 to field of view 2, while also adjusting the distance between the camera and the subject. This ensures that the size of the subject in the frame remains constant, thus only changing the size of the background of the subject.

[0033] However, in actual three-dimensional (3D) game environments, if a wide-angle lens is applied by default, virtual game characters will deform as the 3D space is stretched. Figure 2 This is a schematic diagram illustrating the display status of a virtual game character using a wide-angle lens in related technologies, such as... Figure 2 As shown, (a) shows the virtual game character in the original shot, and (b) shows the virtual game character after applying a wide-angle lens. In comparison, in (b), the virtual game character will deform as the 3D space is stretched.

[0034] In one possible implementation, the inventors, after practical experience and careful research, found that the sliding zoom method commonly used in computer vision still suffers from a poor visual experience for gamers due to the deformation of virtual game characters in wide-angle shots across three-dimensional space. Therefore, this disclosure, which generally applies to 3D games, proposes a method for adjusting the display form of virtual game characters. This method involves acquiring the shooting position and field of view of at least one virtual camera in the game scene, determining the initial form of at least one virtual game character in the game scene corresponding to the field of view, and finally adjusting the initial form using axial compression zoom based on the field of view to obtain the target display form of at least one virtual game character. This achieves the goal of flexibly adjusting the display form of virtual game characters based on the shooting position and field of view of the virtual camera, thereby maintaining a good display form of virtual game characters in wide-angle shots and improving the visual experience for gamers. This solves the technical problem of poor visual experience caused by the deformation of virtual game characters in wide-angle shots across three-dimensional space.

[0035] The methods and embodiments described above in this disclosure can be executed on mobile terminals, computer terminals, or similar computing devices. Taking a mobile terminal as an example, the mobile terminal can be a smartphone, tablet computer, PDA, mobile internet device, PAD, game console, or other terminal device. Figure 3 This is a hardware structure block diagram of a mobile terminal for a method of adjusting the display form of a virtual game character according to an embodiment of this disclosure. Figure 3 As shown, a mobile terminal may include one or more ( Figure 3 Only one is shown in the diagram. Processor 302 (processor 302 may include, but is not limited to, a central processing unit (CPU), graphics processing unit (GPU), digital signal processing (DSP) chip, microprocessor (MCU), programmable logic device (FPGA), neural network processor (NPU), tensor processor (TPU), artificial intelligence (AI) type processor, etc.) and memory 304 for storing data. In one embodiment of this disclosure, it may also include: input / output device 308 and display device 310.

[0036] In some optional embodiments primarily focused on gaming scenarios, the aforementioned device may also provide a human-computer interaction interface with a touch-sensitive surface. This interface can sense finger contact and / or gestures to interact with a graphical user interface (GUI). The human-computer interaction functions may include the following: creating web pages, drawing, word processing, creating electronic documents, playing games, video conferencing, instant messaging, sending and receiving emails, call interfaces, playing digital videos, playing digital music, and / or web browsing, etc. Executable instructions for performing the aforementioned human-computer interaction functions are configured / stored in one or more processor-executable computer program products or readable storage media.

[0037] Those skilled in the art will understand that Figure 3 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 3 The more or fewer components shown, or having the same Figure 3 The different configurations shown.

[0038] According to one embodiment of this disclosure, an embodiment of a method for adjusting the display form of a virtual game character is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0039] In one possible implementation, this disclosure provides a method for adjusting the display form of a virtual game character, providing a graphical user interface through a terminal device, wherein the terminal device may be the aforementioned local terminal device. Figure 4 This is a flowchart of a method for adjusting the display form of a virtual game character according to an embodiment of this application, such as... Figure 4 As shown, the method includes the following steps:

[0040] Step S41: Obtain the shooting position and shooting field of view of at least one virtual camera in the game scene, wherein the shooting field of view is used to determine the field of view of at least one virtual camera at the shooting position;

[0041] Step S42: Determine the initial form of at least one virtual game character in the game scene corresponding to the shooting field of view;

[0042] Step S43: Based on the shooting field of view, the initial form is subjected to axial compression zoom adjustment to obtain the target display form of at least one virtual game character. The axial compression zoom adjustment is used to determine the compression zoom direction corresponding to at least one virtual game character by changing the field of view, and to compress and zoom the initial form according to the compression zoom direction to adjust the display form of at least one virtual game character.

[0043] Optionally, at least one virtual camera has a wide-angle lens.

[0044] The aforementioned game scene can be a 3D game scene. The virtual game characters within this 3D scene can be developed and designed based on anime / manga IPs. Players can control these virtual characters to move or fight using touch controls on the graphical user interface of their terminal devices. At least one virtual camera within the game scene utilizes a wide-angle lens, which can largely reproduce the charm of the anime / manga IP, thereby enhancing the player's gaming experience.

[0045] After obtaining the shooting position and field of view of at least one virtual camera in the game scene, the field of view of at least one virtual camera at that shooting position can be determined based on the field of view, and thus the field of view can be presented in the game scene. Furthermore, the initial form of at least one virtual game character in the game scene corresponding to the shooting field of view is determined; this initial form is the original form data of the virtual game character in the game scene.

[0046] Furthermore, based on the shooting field of view, axial compression zoom adjustment is performed on the initial shape to obtain the target display shape of at least one virtual game character. Specifically, the axial compression zoom adjustment can determine the compression zoom direction corresponding to at least one virtual game character by changing the field of view, and then compress and zoom the initial shape according to the compression zoom direction to adjust the display shape of at least one virtual game character. If the shooting field of view changes, it is manifested as forward compression, that is, compression from the front to the back of the virtual game character based on the shooting field of view; if the shooting field of view does not change, it is manifested as backward compression, that is, compression from the back to the front of the virtual game character based on the shooting field of view, which gives the impression that the shooting field of view has changed.

[0047] Figure 5This is a schematic diagram illustrating the effect of adjusting the display form of a virtual game character according to an embodiment of this application, such as... Figure 5 As shown, (a) the image shows the virtual game character's appearance in the original shot; (b) the image shows the virtual game character's appearance after applying a wide-angle lens, where the game screen has a wider background compared to the original game screen; (c) the image shows the target display form obtained after axial compression and zoom adjustment of the virtual game character's initial form. Figure 5 It is known that the virtual game character displayed in the wide-angle lens differs from the virtual game character displayed in the original lens in terms of shooting field of view, and the virtual game character at the edge of the frame will be deformed to some extent due to the stretching in three-dimensional space. By adjusting the axial compression zoom of the initial shape based on the shooting field of view, at least one target display shape of the virtual game character can be obtained. This allows the shooting field of view of at least one virtual game character displayed in the wide-angle lens to change from that of the virtual character displayed in the original lens, thus allowing more background to be presented in the image, while the display shape of the virtual game character only undergoes little or no deformation, resulting in a better visual effect for the game.

[0048] Based on steps S41 to S43 above, by obtaining the shooting position and shooting field of view of at least one virtual camera in the game scene, the initial form of at least one virtual game character in the game scene corresponding to the shooting field of view is determined. Finally, the initial form is axially compressed and zoomed based on the shooting field of view to obtain the target display form of at least one virtual game character. This achieves the purpose of flexibly adjusting the display form of the virtual game character based on the shooting position and shooting field of view of the virtual camera. This achieves the technical effect of maintaining a good display form of the virtual game character in the wide-angle image and improving the visual experience of the game player. It also solves the technical problem that the virtual game character in the wide-angle image will deform with the three-dimensional space, resulting in a poor visual experience for the game player.

[0049] The method for adjusting the display form of virtual game characters in the embodiments of this application will be further described below.

[0050] Optionally, at least one virtual camera includes: a single virtual camera, in step S43, performing axial compression zoom adjustment on the initial shape based on the shooting field of view to obtain the target display shape of at least one virtual game character, including:

[0051] Step S431: Determine the initial coordinate information of the model surface pixels of at least one virtual game character using the initial shape, wherein the initial coordinate information of the model surface pixels is used to record the initial world coordinates of the model surface pixels.

[0052] Step S432: Based on the shooting field of view and the initial coordinate information of the model surface pixels, obtain the pixel displacement value corresponding to the initial coordinate information of the model surface pixels;

[0053] Step S433: The initial shape is axially compressed and zoomed to adjust using the initial coordinate information and pixel displacement value of the model surface pixels to obtain target coordinate information, wherein the target coordinate information is used to record the target world coordinates of the model surface pixels.

[0054] Step S434: Determine the target display form of at least one virtual game character using the target coordinate information.

[0055] Specifically, the initial world coordinates of at least one virtual game character's model surface pixels are determined using the initial shape. Then, the pixel displacement value corresponding to the initial world coordinates is obtained based on the shooting field of view and the initial world coordinates. Furthermore, by superimposing the pixel displacement value with the initial world coordinates, the target world coordinates of the model surface pixels after adjustment can be obtained. The target world coordinates can be used to determine the target display shape of at least one virtual game character, thereby resisting the distortion caused by adjusting the virtual game character under a wide-angle lens, making the virtual game character more aesthetically pleasing in front of the wide-angle lens.

[0056] Based on the above optional embodiments, by using the initial shape to determine the initial coordinate information of the surface pixels of at least one virtual game character, and then based on the shooting field of view and the initial coordinate information of the surface pixels of the model, the pixel displacement value corresponding to the initial coordinate information of the surface pixels of the model is obtained. Subsequently, the initial shape is axially compressed and zoomed using the initial coordinate information of the surface pixels of the model and the pixel displacement value to obtain the target coordinate information. Finally, the target display shape of at least one virtual game character is determined by the target coordinate information, thereby improving the aesthetics of the virtual game character in the game scene and further improving the visual experience of the game player.

[0057] Optionally, in step S432, obtaining the pixel displacement value corresponding to the initial coordinate information of the model surface pixels based on the shooting field of view and the initial coordinate information of the model surface pixels includes: obtaining the pixel displacement value corresponding to the initial coordinate information of the model surface pixels based on the shooting field of view, the initial coordinate information of the model surface pixels and a preset adjustment control value, wherein the preset adjustment control value is used to adjust the display thickness of at least one virtual game character in the shooting direction corresponding to the shooting field of view.

[0058] Specifically, when at least one virtual camera is a single virtual camera, the display thickness of the virtual game character in the shooting direction corresponding to the shooting field of view is adjusted using this single virtual camera, thereby maintaining a good display form of the virtual game character in the wide-angle shot. The display thickness of the virtual game character in the shooting direction corresponding to the shooting field of view is mainly adjusted using preset adjustment control values. These preset adjustment control values ​​can be flexibly set by the user. The larger the absolute value of the preset adjustment control value, the greater the adjustment range of the display thickness, and vice versa.

[0059] Based on the above optional implementation methods, by using the shooting field of view, the initial coordinate information of the model surface pixels, and the preset adjustment control value, the pixel displacement value corresponding to the initial coordinate information of the model surface pixels can be quickly obtained, so as to flexibly adjust the display form of the virtual game character.

[0060] Optionally, based on the shooting field of view, the initial coordinate information of the model surface pixels, and preset adjustment control values, the pixel displacement value corresponding to the initial coordinate information is obtained, including:

[0061] Step S4321: Determine the first vector using the initial coordinate information of the shooting field of view and the model surface pixels. The first vector is the perpendicular vector between the model surface pixels and the target virtual plane. The target virtual plane passes through the center of at least one virtual game character model and is perpendicular to the shooting direction.

[0062] Step S4322: Based on the first vector and the preset adjustment control value, obtain the pixel displacement value corresponding to the initial coordinate information of the pixel on the model surface.

[0063] Specifically, the first vector perpendicular to the target virtual plane is determined by using the shooting field of view and the initial coordinate information of the model surface pixels. Then, the first vector is multiplied with the preset adjustment control value to obtain the pixel displacement value corresponding to the initial coordinate information of the model surface pixels.

[0064] Based on the above optional implementation method, a first vector is determined by using the shooting field of view and the initial coordinate information of the model surface pixels. Then, the pixel displacement value corresponding to the initial coordinate information of the model surface pixels is obtained based on the first vector and the preset adjustment control value, so as to flexibly adjust the display form of the virtual game character.

[0065] Optionally, in step S4321, determining the first vector using the initial coordinate information of the shooting field of view and the pixels on the model surface includes:

[0066] Step S501: Obtain the second vector corresponding to the shooting field of view, wherein the second vector is the virtual camera front vector determined along the positive direction of the shooting direction;

[0067] Step S502: Determine the model center using the bounding box of at least one virtual game character;

[0068] Step S503: Determine the third vector using the initial coordinate information of the model center and the model surface pixels, wherein the third vector is the vector between the model surface pixels and the model center;

[0069] Step S504: Calculate the first vector based on the second vector and the third vector.

[0070] Optionally, in step S504, calculating the first vector based on the second vector and the third vector includes: performing a dot product calculation on the second vector and the third vector to obtain the first vector.

[0071] Figure 6 This is a schematic diagram illustrating a method for adjusting the display form of a virtual game character according to an embodiment of this application, such as... Figure 6 As shown, the second vector corresponding to the shooting field of view is obtained. The second vector is the virtual camera front vector determined along the shooting direction. After determining the model center using the model bounding box of the virtual game character, the third vector (i.e., the vector pointing from the model center to the front of the virtual game character) is determined using the initial coordinate information of the model center and the model surface pixels. The second vector and the third vector are multiplied to obtain the first vector, which is the perpendicular vector between the model surface pixels and the target virtual plane.

[0072] Figure 7 This is a schematic diagram illustrating another method for adjusting the display form of a virtual game character according to an embodiment of this application, such as... Figure 7 As shown, the second vector corresponding to the shooting field of view is obtained. The second vector is still the virtual camera back vector determined in the positive direction along the shooting direction. After determining the model center using the model bounding box of the virtual game character, the third vector (i.e., the vector pointing from the model center to the back of the virtual game character) is determined using the initial coordinate information of the model center and the model surface pixels. The second vector and the third vector are multiplied to obtain the first vector, which is the perpendicular vector between the model surface pixels and the target virtual plane.

[0073] It should be noted that the aforementioned virtual camera front vector, determined in the forward direction of the shooting direction, is one optional implementation of the second vector and does not constitute an undue limitation on this application. In actual calculations, the second vector can also be other types of vectors. For example, the second vector can also be a virtual camera back vector determined in the reverse direction of the shooting direction, or the second vector can simultaneously use both the virtual camera front vector and the virtual camera back vector. Furthermore, during the calculation of the second vector using different types of vectors, corresponding adjustment control values ​​are set for each type of vector. By adjusting these control values, the calculation is performed using the first vector and the initial shape data of the virtual game character, thereby achieving flexible control over the thickness of the virtual game character.

[0074] use Figure 6 , Figure 7 The first vector calculated in the middle and the preset adjustment control value can adjust the initial shape of the virtual game character, such as compressing it along the direction of the virtual camera, so as to present the virtual game character as a flattened shape. This allows the virtual game character to be displayed as forward compression, that is, compressed from the front to the back of the virtual game character based on the shooting field of view. Figure 8 This is a schematic diagram illustrating another method for adjusting the display form of a virtual game character according to an embodiment of this application, such as... Figure 8 As shown, when a flattened virtual game character is presented in a wide-angle shot, it can resist the distortion caused by spatial stretching, reduce the sense of space in the image, and thus enhance the aesthetics of the virtual game character.

[0075] Figure 9 This is a schematic diagram illustrating another method for adjusting the display form of a virtual game character according to an embodiment of this application, such as... Figure 9 As shown, to enhance the sense of space in the image, one can also utilize... Figure 6 , Figure 7 The first vector calculated in the middle and the preset adjustment control value can adjust the initial shape of the virtual game character, thus presenting a thickened shape of the virtual game character. The adjustment amount of the virtual camera position and field of view can be 0, so only the display thickness of the virtual game character is adjusted, such as... Figure 9 As shown, by adjusting the thickness of the virtual game character display, the sense of space in the image can be enhanced.

[0076] Based on the above optional implementation, by obtaining the second vector corresponding to the shooting field of view, the model center is determined by using the model bounding box of at least one virtual game character. Then, the third vector is determined by using the initial coordinate information of the model center and the model surface pixels. The third vector is the vector between the model surface pixels and the model center. Finally, the first vector can be quickly calculated based on the second and third vectors, which is used to determine the pixel displacement value corresponding to the initial coordinate information of the model surface pixels, so as to realize flexible adjustment of the display form of the virtual game character.

[0077] Optionally, in step S4321, determining the first vector using the initial coordinate information of the shooting field of view and the pixels on the model surface includes:

[0078] Step S601: Determine the model center using the bounding box of at least one virtual game character;

[0079] Step S602: The third vector is determined by using the initial coordinate information of the model center and the model surface pixels, and the fourth vector is determined by using the model center and the shooting field of view. The third vector is the vector between the model surface pixels and the model center, and the fourth vector is the vector of at least one virtual camera pointing to the model center within the field of view of the shooting field of view.

[0080] Step S603: Calculate the first vector based on the third and fourth vectors.

[0081] Optionally, in step S603, calculating the first vector based on the third vector and the fourth vector includes: performing a dot product of the direction vectors of the third vector and the fourth vector to obtain the first vector.

[0082] Specifically, the model center is determined by using the bounding box of at least one virtual game character model. Then, the initial coordinate information of the model center and the pixels on the model surface is used to determine the third vector, and the model center and the shooting field of view are used to determine the fourth vector. Subsequently, the first vector is obtained by performing a dot product calculation based on the direction vectors of the third and fourth vectors. This allows the virtual game character's facing direction to revolve around the virtual camera, thus ensuring that it is always displayed in the front of the game screen.

[0083] Figure 10 This is a schematic diagram illustrating another method for adjusting the display form of a virtual game character according to an embodiment of this application. Figure 10In the process of axial compression zoom adjustment of the initial shape based on the shooting field of view, the initial coordinate information of the model surface pixels, and preset adjustment control values, the first vector can be calculated either based on the second and third vectors, or based on the third and fourth vectors. When the first vector is calculated based on the second and third vectors, the target virtual plane passes through the center of each virtual game character's model and is perpendicular to the second vector. The shooting direction corresponds to this second vector. When the first vector is calculated based on the third and fourth vectors, the target virtual plane passes through the center of each virtual game character's model and is perpendicular to the fourth vector corresponding to each virtual game character. The shooting direction corresponds to this fourth vector. Then, based on the first vector and the preset adjustment control values, the pixel displacement value corresponding to the initial coordinate information of the model surface pixels is obtained. The target coordinate information is obtained using the initial coordinate information and pixel displacement value of the model surface pixels, and the target display shape of at least one virtual game character is determined through the target coordinate information. This allows the facing direction of the virtual game character to revolve around the virtual camera, thus ensuring a frontal display in the game screen.

[0084] Based on the above optional implementation, the model center is determined by using the bounding box of at least one virtual game character model, and then the third vector is determined by using the initial coordinate information of the model center and the pixels on the model surface, and the fourth vector is determined by using the model center and the shooting field of view. Finally, the first vector is calculated based on the third vector and the fourth vector, which is used to determine the pixel displacement value corresponding to the initial coordinate information of the pixels on the model surface, so as to realize the flexible adjustment of the display form of the virtual game character.

[0085] Optionally, determining the third vector using the initial coordinate information of the model center and the model surface pixels includes: subtracting the initial world coordinates of the model surface pixels from the world coordinates of the model center to obtain the third vector.

[0086] Figure 11 This is a schematic diagram of a third vector according to an embodiment of this application, such as... Figure 11 As shown, subtracting the initial world coordinates of the pixels on the model surface from the world coordinates of the model center can quickly yield the third vector.

[0087] Optionally, at least one virtual camera includes: multiple virtual cameras, and in step S43, the initial shape is adjusted by axial compression zoom based on the shooting field of view to obtain the target display shape of at least one virtual game character, including:

[0088] Step S435: Determine the initial coordinate information of the model surface pixels of at least one virtual game character using the initial shape, wherein the initial coordinate information of the model surface pixels is used to record the initial world coordinates of the model surface pixels.

[0089] Step S436: Based on the shooting field of view and the initial coordinate information of the model surface pixels, obtain the pixel displacement value corresponding to the initial coordinate information of the model surface pixels;

[0090] Step S437: The initial shape is axially compressed and zoomed to adjust using the initial coordinate information and pixel displacement value of the model surface pixels to obtain target coordinate information, wherein the target coordinate information is used to record the target world coordinates of the model surface pixels.

[0091] Step S438: By performing game scene image compositing processing on the target coordinate information, the target display form of at least one virtual game character is obtained.

[0092] Specifically, when at least one virtual camera includes multiple virtual cameras, additional virtual cameras are used to independently capture virtual game characters to obtain target coordinate information. Then, by performing game scene image compositing on the target coordinate information, the target display form of at least one virtual game character is obtained, thereby further enriching the ways to adjust the display form of virtual game characters.

[0093] Based on the above optional implementation method, the initial coordinate information of the surface pixels of at least one virtual game character is determined by using the initial shape. Then, based on the shooting field of view and the initial coordinate information of the surface pixels, the pixel displacement value corresponding to the initial coordinate information of the surface pixels is obtained. Subsequently, the initial shape is axially compressed and zoomed to obtain the target coordinate information by using the initial coordinate information and the pixel displacement value of the surface pixels. Finally, the target display shape of at least one virtual game character is obtained by compositing and rendering the game scene image based on the target coordinate information. This can resist the deformation of the virtual game character under the adjustment of the wide-angle lens, making the virtual game character more beautiful in front of the wide-angle lens.

[0094] Traditional wide-angle shooting techniques, such as Hitchcock zoom, can distort virtual game characters. In this embodiment, by acquiring the shooting position and field of view of at least one virtual camera in the game scene, the initial form of at least one virtual game character in the game scene corresponding to the field of view is determined. Finally, based on the field of view, axial compression zoom is applied to the initial form to obtain the target display form of at least one virtual game character. This asynchronous axial compression zoom can resist the distortion of virtual game characters, making them more aesthetically pleasing in front of a wide-angle lens and further enhancing the visual experience for gamers. Anime works often intentionally create inconsistencies between the spatial structure of characters and scenes for aesthetic purposes. The solution in this embodiment can effectively reproduce this effect, making it well-suited for games and films with anime IP rendering styles.
