[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 202310937018.3, filed on July 27, 2023, entitled “Virtual object rendering method and device, storage medium and electronic device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of computer technology, and in particular to a virtual object rendering method, a virtual object model rendering device, a computer-readable storage medium, and an electronic device. Background Art

[0004] With the development of terminal devices and the gaming industry, a large number of games or works of different themes have emerged to meet the needs of users. In some two-dimensional games, there is a need to display the fluttering of some flags.

[0005] In related technologies, flag waving can be achieved through a sequential frame approach. Specifically, a sequential frame animation is a form of animation built on continuous static images, typically consisting of a series of static images (frames) played sequentially. During playback, multiple frames are played continuously per second, switching between static images frame by frame, creating a continuous dynamic effect. The changes between each frame can be in terms of position, shape, color, etc., and these changes can be used to present effects such as the movement, deformation, and transformation of an object.

[0006] However, in the related art, the file size of the sequence frames is usually large, the resolution of the sequence frame images is low, and a high frame rate is required to present a smooth fluttering effect. In addition, the cost of producing multiple sequence frames is high and the production efficiency is poor.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0036] FIG1 is a schematic diagram showing an exemplary system architecture of a virtual object rendering method to which an embodiment of the present disclosure can be applied.

[0037] As shown in Figure 1, system architecture 1000 may include one or more terminal devices 1001, 1002, and 1003, a network 1004, and a server 1005. Network 1004 is a medium for providing communication links between terminal devices 1001, 1002, and 1003 and server 1005. Network 1004 may include various connection types, such as wired or wireless communication links or fiber optic cables.

[0038] It should be understood that the number of terminal devices, networks, and servers in FIG1 is merely illustrative. Any number of terminal devices, networks, and servers may be provided as needed. For example, server 1005 may be a server cluster consisting of multiple servers.

[0039] Users can use terminal devices 1001, 1002, and 1003 to interact with server 1005 via network 1004 to receive or send messages, etc. Terminal devices 1001, 1002, and 1003 can be various electronic devices with display screens, including but not limited to smartphones, tablet computers, laptop computers, and desktop computers. In addition, server 1005 can be a server that provides various services.

[0040] In one embodiment, the executor of the virtual object rendering method disclosed herein may be server 1005, which may obtain the first coordinate variable and the second coordinate variable, the first noise map and the second noise map sent by terminal devices 1001, 1002, and 1003, sample the first noise map through the first coordinate variable to obtain a first sampling result, sample the second noise map through the second coordinate variable to obtain a second sampling result, interpolate the first sampling result and the second sampling result to obtain a third sampling result, obtain the texture map corresponding to the virtual object, superimpose the third sampling result on the map coordinates to obtain the target map coordinates, and sample the texture map through the target map coordinates to render the floating effect of the virtual object in two-dimensional space.

[0041] In addition, the virtual object rendering method disclosed in the present invention can also be executed through terminal devices 1001, 1002, 1003, etc. to obtain the first coordinate variable and the second coordinate variable, obtain the first noise map and the second noise map, sample the first noise map through the first coordinate variable to obtain a first sampling result, sample the second noise map through the second coordinate variable to obtain a second sampling result, interpolate the first sampling result and the second sampling result to obtain a third sampling result, obtain the texture map corresponding to the virtual object, superimpose the third sampling result on the map coordinates to obtain the target map coordinates, and sample the texture map through the target map coordinates to render the floating effect of the virtual object in two-dimensional space.

[0042] In addition, the implementation process of the method for generating special effects of the present disclosure can also be implemented jointly by the terminal devices 1001, 1002, 1003 and the server 1005. For example, the terminal devices 1001, 1002, 1003 can obtain the first coordinate variable and the second coordinate variable, obtain the first noise map and the second noise map, sample the first noise map using the first coordinate variable to obtain a first sampling result, sample the second noise map using the second coordinate variable to obtain a second sampling result, and then send the obtained first sampling result and second sampling result to the server 1005, so that the server 1005 can interpolate the first sampling result and the second sampling result to obtain a third sampling result, obtain the texture map corresponding to the virtual object, superimpose the third sampling result on the map coordinates to obtain the target map coordinates, and sample the texture map using the target map coordinates to render the floating effect of the virtual object in the two-dimensional space.

[0043] In an exemplary embodiment of the present disclosure, a first coordinate variable and a second coordinate variable can be obtained, a first noise map and a second noise map can be obtained, the first noise map is sampled using the first coordinate variable to obtain a first sampling result, the second noise map is sampled using the second coordinate variable to obtain a second sampling result, the first sampling result and the second sampling result are interpolated to obtain a third sampling result, a texture map corresponding to the virtual object is obtained, the third sampling result is superimposed on the map coordinates to obtain the target map coordinates, and the texture map is sampled using the target map coordinates to render a floating effect of the virtual object in a two-dimensional space. Referring to FIG2 , a flowchart of a virtual object rendering method in this exemplary embodiment is shown, which may include the following steps:

[0044] Step S210, obtaining a first coordinate variable and a second coordinate variable, and obtaining a first noise map and a second noise map;

[0045] Step S220, sampling the first noise image using the first coordinate variable to obtain a first sampling result, and sampling the second noise image using the second coordinate variable to obtain a second sampling result;

[0046] Step S230, interpolating the first sampling result and the second sampling result to obtain a third sampling result;

[0047] Step S240, obtaining a texture map corresponding to the virtual object; wherein the virtual object is a two-dimensional virtual object in a two-dimensional space, and the texture map corresponds to a mapping coordinate;

[0048] Step S250 , superimposing the third sampling result on the mapping coordinates to obtain target mapping coordinates, and sampling the texture map according to the target mapping coordinates to render a floating effect of the virtual object in a two-dimensional space.

[0049] In a virtual object rendering method provided by an embodiment of the present disclosure, a first coordinate variable and a second coordinate variable can be obtained, a first noise map and a second noise map can be obtained, the first noise map is sampled by the first coordinate variable to obtain a first sampling result, the second noise map is sampled by the second coordinate variable to obtain a second sampling result, the first sampling result and the second sampling result are interpolated to obtain a third sampling result, a texture map corresponding to the virtual object is obtained, the map coordinates are superimposed with the third sampling result to obtain a target map coordinate, and the texture map is sampled by the target map coordinate to render the floating effect of the virtual object in a two-dimensional space. Through the scheme of the present disclosure, on the one hand, the floating effect of the virtual object can be achieved by difference, which occupies less space and has a higher resolution, and can achieve a smooth floating effect; on the other hand, the floating effect of the virtual object can be achieved by interpolation, without the need to produce multiple sequence frame images, and the cost of achieving the floating effect is low and the efficiency is high.

[0050] Next, steps S210 to S250 of the virtual object rendering method in this exemplary embodiment will be described in more detail with reference to FIG. 2 and the embodiment.

[0051] Step S210, obtaining a first coordinate variable and a second coordinate variable, and obtaining a first noise map and a second noise map;

[0052] In an exemplary embodiment of the present disclosure, a first coordinate variable and a second coordinate variable may be obtained. Specifically, the first coordinate variable and the second coordinate variable are a two-dimensional coordinate group, and the first coordinate variable or the second coordinate variable may be used to indicate a sampling position.

[0053] For example, the first coordinate variable and the second coordinate variable may be UV coordinate variables (UV Coordinates, texture coordinates).

[0054] In an exemplary embodiment of the present disclosure, a first noise map and a second noise map may be obtained. Specifically, the first noise map and the second noise map may be images used to generate natural textures and simulate natural phenomena. For example, the first noise map and the second noise map may include grayscale images containing random brightness values, which can be used to simulate various natural scenes.

[0055] In an exemplary embodiment of the present disclosure, the first noise map and the second noise map may be generated by a random algorithm, such as Perlin noise, Simplex noise, Worley noise, etc.

[0056] It should be noted that the present disclosure does not impose any special limitation on the method of generating the first noise map and the second noise map.

[0057] Step S220, sampling the first noise image using the first coordinate variable to obtain a first sampling result, and sampling the second noise image using the second coordinate variable to obtain a second sampling result;

[0058] In an exemplary embodiment of the present disclosure, after obtaining the first and second coordinate variables and the first and second noise maps through the above steps, the first noise map can be sampled using the first coordinate variables to obtain a first sampling result, and the second noise map can be sampled using the second coordinate variables to obtain a second sampling result. Specifically, sampling the noise map using the coordinate variables refers to obtaining one or more values ​​from the noise map. When sampling the noise map, the noise image can be viewed as a two-dimensional pixel matrix, where each pixel contains a different value.

[0059] For example, to generate rock textures, you can use the Perlin noise algorithm to convert the noise map into height map data, and then use the height map data to highly deform the rock model to generate the shape and surface texture of the rock; to simulate clouds, you can use the Simplex noise algorithm to convert the noise map into brightness values, and then use the brightness values ​​to perform material mapping on the clouds in the scene, thereby simulating the softness and dynamic effects of the clouds.

[0060] Furthermore, the first sampling result, the second sampling result, and the third sampling result are random numbers. Specifically, when sampling a noise image, the noise image can be regarded as a two-dimensional pixel matrix, where each pixel contains a different value. By interpolating the coordinates on the noise image, a set of random numbers can be obtained. These values ​​can be used to generate various natural textures and simulate natural phenomena.

[0061] It should be noted that the present disclosure does not specifically limit the specific manner of obtaining the first sampling result by sampling the first noise map through the first coordinate variable and obtaining the second sampling result by sampling the second noise map through the second coordinate variable.

[0062] Step S230, interpolate the first sampling result and the second sampling result to obtain a third sampling result;

[0063] In an exemplary embodiment of the present disclosure, after obtaining the first sampling result and the second sampling result through the above steps, the first sampling result and the second sampling result can be interpolated to obtain a third sampling result. Specifically, interpolating the first sampling result and the second sampling result to obtain a third sampling result means obtaining a new sampling result (the third sampling result) through an interpolation method based on two known sampling results. This interpolation method can be used for texture blending, detailed textures, transition effects, etc.

[0064] In an exemplary embodiment of the present disclosure, methods such as linear interpolation, bilinear interpolation, and trilinear interpolation can be used to interpolate the first sampling result and the second sampling result to obtain a third sampling result. Among them, for linear interpolation, assuming that the change between two sampling points is linear, the value of any point is calculated through a linear equation; for bilinear interpolation, linear interpolation is performed separately in the horizontal and vertical directions to obtain a smoother effect; for trilinear interpolation, linear interpolation is performed in three dimensions, usually used for processing stereo images, volume data, etc.

[0065] In an exemplary embodiment of the present disclosure, the lerp function (interpolation function) can be used to interpolate the first sampling result and the second sampling result to obtain a third sampling result.

[0066] For example, the lerp function can be used to interpolate the first sampling result and the second sampling result to obtain a third sampling result. Specifically, the expression of the lerp function is as follows: lerp(a, b, t) = (1 - t) * a + t * b

[0067] Where, a is the first sampling result, b is the second sampling result, and t is the interpolation scale factor, with a value range of 0 to 1. When t = 0, the lerp function returns a; when t = 1, the lerp function returns b; when 0 < t < 1, the lerp function returns the interpolation result between a and b.

[0068] In an exemplary embodiment of the present disclosure, the lerp function (interpolation function) can be used to interpolate the first sampling result and the second sampling result to obtain a third sampling result. Specifically, the expression is as follows: c = lerp(a, b, t)

[0069] Among them, c is the third sampling result, a is the first sampling result, b is the second sampling result, t is the interpolation scale factor, and its value range is 0 to 1. When t = 0, c is equal to a; when t = 1, c is equal to b; when 0 < t < 1, c is the interpolation result between a and b.

[0070] It should be noted that the present disclosure does not make special limitations on the specific manner of interpolating the first sampling result and the second sampling result to obtain the third sampling result.

[0071] For example, the first coordinate variable uv1 can be obtained, the second coordinate variable uv2 can be obtained, the first noise map noisetex1 and the second noise map noisetex2 can be obtained. The sample2D function (sampling function) can be used as the sampling function. The first noise map is sampled by the first coordinate variable to obtain the first sampling result, and the second noise map is sampled by the second coordinate variable to obtain the second sampling result. The code is as follows: float4 tex1 = sample2D(noisetex1, uv1) float4 tex2 = sample2D(noisetex2, uv2)

[0072] Among them, float4 tex1 is the first sampling result, float4 tex2 is the second sampling result, and then the third sampling result (float4 finalColor) is obtained by interpolating float4 tex1 and float4 tex2. The code is as follows: float4 finalColor = lerp(tex1, tex2, 0.5), where t is 0.5.

[0073] Step S240, obtain the texture map corresponding to the virtual object;

[0074] In an exemplary embodiment of the present disclosure, after obtaining the third sampling result through the above steps, the texture map corresponding to the virtual object can be obtained. Among them, the virtual object is a two-dimensional virtual object in a two-dimensional space, and the texture map corresponds to texture coordinates. Specifically, the texture map usually consists of one or more pictures, and can be pictures, patterns, texts, etc., for simulating the appearance and material of the object surface. The texture map can contain information such as different colors, textures, transparencies, reflectivities, etc., so as to achieve various realistic and vivid picture effects.

[0075] In an exemplary embodiment of the present disclosure, the texture map corresponds to texture coordinates. Specifically, the texture coordinates are a two-dimensional coordinate group, used to represent the corresponding relationship when pasting the texture map content onto the virtual object. When the texture map of the virtual object is pasted onto the virtual object, the pixel information of the texture map can be projected onto the virtual object according to the above corresponding relationship, so as to achieve the texture map.

[0076] It should be noted that the present disclosure does not impose any special restrictions on the specific type of texture map corresponding to the virtual object.

[0077] Step S250 , superimposing the third sampling result on the mapping coordinates to obtain target mapping coordinates, and sampling the texture map according to the target mapping coordinates to render a floating effect of the virtual object in a two-dimensional space.

[0078] In an exemplary embodiment of the present disclosure, after obtaining the third sampling result and the texture map corresponding to the virtual object through the above steps, the third sampling result can be superimposed on the texture coordinates to obtain target texture coordinates. Specifically, superimposing the third sampling result on the texture coordinates to obtain the target texture coordinates refers to combining the texture coordinates with the interpolated sampling result to obtain the final target texture coordinates.

[0079] Specifically, the third sampling result (random value) may be superimposed on the mapping coordinates to change the values ​​of the mapping coordinates and obtain target mapping coordinates.

[0080] It should be noted that the present disclosure does not impose any special limitation on the specific method of obtaining the target mapping coordinates by superimposing the third sampling result on the mapping coordinates.

[0081] In an exemplary embodiment of the present disclosure, after obtaining the target mapping coordinates through the above steps, the texture map can be sampled using the target mapping coordinates to render a floating effect of the virtual object in two-dimensional space. Specifically, sampling the texture map using the target mapping coordinates means obtaining the color value of the corresponding position on the texture map using the target mapping coordinates. After obtaining the color value, it can be applied to the virtual object and rendered to achieve a floating effect of the virtual object in two-dimensional space.

[0082] In an exemplary embodiment of the present disclosure, rendering can be performed by a shader. Specifically, a shader is a rendering program used to perform specific calculations in computer graphics rendering to generate the final image output. The shader is written in a programming language such as GLSL (Open Graphics Library Shading Language, a cross-platform graphics programming interface shading language), HLSL (High-Level Shader Language, a high-level shader language), Cg (Collada Effect shading language, an open standard effect shading language for digital content), etc. It can be executed on a GPU (Graphics Processing Unit) and can achieve a variety of rendering effects and graphic effects. Shaders can be divided into multiple types, including vertex shaders, fragment shaders, geometry shaders, compute shaders, etc. Each shader has specific functions and input / output. By writing different types of shader programs, a variety of rendering effects can be achieved, including shadows, reflections, anti-aliasing, etc.

[0083] Specifically, the rendering process of virtual objects can be implemented according to the rendering pipeline. Specifically, the rendering pipeline includes multiple processing steps, such as geometry processing, lighting, texturing, depth testing, etc. The rendering pipeline is usually divided into two stages: vertex processing stage and pixel processing stage.

[0084] Among them, the vertex processing stage mainly includes the following four steps:

[0085] Vertex input: passing the vertex data of the virtual object into the rendering pipeline; Vertex shader: transforming and deforming each vertex and converting it into screen space coordinates; Geometry shader: generating geometric graphics, such as triangles, based on vertex data; Rasterization: converting geometric graphics into pixels and passing the pixels into the pixel processing stage.

[0086] The pixel processing stage mainly includes the following three steps:

[0087] Pixel shader: performs lighting, texture and other calculations on each pixel to generate the final color value; pixel depth test: determines whether the pixel is visible based on the depth value, thereby achieving occlusion culling and transparency effects; pixel output: outputs the processed pixels to the screen or texture.

[0088] It should be noted that the present disclosure does not impose any special limitation on the method of rendering virtual objects.

[0089] In an exemplary embodiment of the present disclosure, the third sampling result can be superimposed on the mapping coordinates to obtain intermediate mapping coordinates, the first direction coordinates can be adjusted according to the bending strength parameter to obtain the target first direction coordinates, the second direction coordinates can be adjusted according to the forward and backward sway parameter and the forward and backward floating perspective parameter to obtain the target second direction coordinates, and the target mapping coordinates can be determined based on the target first direction coordinates and the target second direction coordinates. Referring to FIG. 3 , determining the target mapping coordinates based on the target first direction coordinates and the target second direction coordinates can include the following steps S310 to S330:

[0090] Step S310, superimposing the third sampling result on the mapping coordinates to obtain intermediate mapping coordinates;

[0091] In an exemplary embodiment of the present disclosure, after obtaining the third sampling result and the texture coordinates through the above steps, the third sampling result can be superimposed on the texture coordinates to obtain intermediate texture coordinates. The intermediate texture coordinates include first-direction coordinates and second-direction coordinates. Specifically, superimposing the third sampling result on the texture coordinates to obtain the intermediate texture coordinates refers to combining the texture coordinates with the interpolated sampling result to obtain the intermediate texture coordinates. These intermediate texture coordinates require further processing before sampling the texture map corresponding to the virtual object.

[0092] Specifically, the third sampling result (random value) may be superimposed on the mapping coordinates to change the values ​​of the mapping coordinates and obtain intermediate mapping coordinates.

[0093] It should be noted that the present disclosure does not impose any special limitation on the specific method of superimposing the third sampling result on the mapping coordinates to obtain the intermediate mapping coordinates.

[0094] Step S320, adjusting the first direction coordinate according to the bending strength parameter to obtain the target first direction coordinate, and adjusting the second direction coordinate according to the front-back sway parameter and the front-back floating perspective parameter to obtain the target second direction coordinate;

[0095] In an exemplary embodiment of the present disclosure, after obtaining the intermediate mapping coordinates through the above steps, the first-direction coordinates can be adjusted according to the bending strength parameter to obtain the target first-direction coordinates. The bending strength parameter indicates the bending amplitude of the virtual object, the fore-and-aft sway parameter indicates the fore-and-aft sway amplitude of the virtual object, and the fore-and-aft perspective parameter indicates the fore-and-aft perspective state of the virtual object. Specifically, the intermediate mapping coordinates include first-direction coordinates and second-direction coordinates. For example, the intermediate mapping coordinates are UV coordinates, which include U-direction coordinates and V-direction coordinates.

[0096] Specifically, after obtaining the intermediate mapping coordinates, the first direction coordinates can be adjusted in combination with a bending strength parameter to obtain the target first direction coordinates. The bending strength parameter is used to indicate the bending amplitude of the virtual object. A higher bending strength parameter indicates a greater bending amplitude of the virtual object, while a lower bending strength parameter indicates a smaller bending amplitude. Alternatively, a higher bending strength parameter indicates a smaller bending amplitude of the virtual object, while a lower bending strength parameter indicates a greater bending amplitude of the virtual object.

[0097] For example, the value of the first direction coordinate may be multiplied by the bending strength parameter to obtain the target first direction coordinate.

[0098] In one exemplary embodiment of the present disclosure, the bending amplitude of a virtual object can be controlled using a power (exponential) function. Specifically, a power function represents the result of raising a number (radix) to a power of a positive integer (exponent). The target's first direction coordinate can be obtained using the power function, which can be represented by the formula y = x^n, where x is the radix, n is the exponent, and y is the result.

[0099] Specifically, the bending strength parameter can be used as an index to adjust the first direction coordinate. The code is as follows, where T is the target first direction coordinate:

[0100] T=power (first direction coordinate, bending strength parameter).

[0101] Furthermore, the target first direction coordinate can be determined based on the value obtained by the power function and the first direction coordinate. For example, X=(0.5-first direction coordinate)*T, where X is the target first direction coordinate and T is the value obtained by the power function.

[0102] In an exemplary embodiment of the present disclosure, after obtaining the intermediate mapping coordinates through the above steps, the second-direction coordinates are adjusted based on the sway parameter and the forward and backward floating perspective parameter to obtain the target second-direction coordinates. Specifically, after obtaining the intermediate mapping coordinates, the second-direction coordinates can be adjusted based on the sway parameter and the forward and backward floating perspective parameter to obtain the target second-direction coordinates. The sway parameter indicates the sway amplitude of the virtual object, and the forward and backward floating perspective parameter indicates the forward and backward perspective state of the virtual object.

[0103] The higher the sway parameter, the greater the sway amplitude of the virtual object, while the lower the sway parameter, the smaller the sway amplitude. Alternatively, the higher the sway parameter, the smaller the sway amplitude of the virtual object, while the lower the sway parameter, the greater the sway amplitude of the virtual object. A higher sway perspective parameter moves the virtual object closer to the front, while a lower sway perspective parameter moves the virtual object closer to the back. Alternatively, a higher sway perspective parameter moves the virtual object closer to the back, while a lower sway perspective parameter moves the virtual object closer to the front.

[0104] For example, the target second direction coordinate may be obtained by multiplying the value of the second direction coordinate, the front-back sway parameter, and the front-back drift perspective parameter.

[0105] Furthermore, the target second-direction coordinate can be determined based on the calculation result of the power function, the sway parameter, and the flutter perspective parameter. For example, the bending strength parameter can be used as an exponent: T = power (second-direction coordinate, bending strength parameter), and the target second-direction coordinate is Y = sway parameter * flutter perspective parameter * T.

[0106] For example, as shown in FIG4 , the front and back floating perspective parameters are different, and the front and back perspective states of the virtual object are different.

Specifically, the target first-direction coordinates can be used as the first coordinate component of the target mapping coordinates, and the target second-direction coordinates can be used as the second coordinate component of the target mapping coordinates to obtain the target mapping coordinates.

[0109] It should be noted that the present disclosure does not impose any special limitation on the specific method of determining the target mapping coordinates according to the target first direction coordinates and the target second direction coordinates.

[0110] Through the above steps S310 to S330, the third sampling result can be superimposed on the mapping coordinates to obtain the intermediate mapping coordinates, the first direction coordinates can be adjusted according to the bending strength parameter to obtain the target first direction coordinates, the second direction coordinates can be adjusted according to the front and back swing parameters and the front and back floating perspective parameters to obtain the target second direction coordinates, and the target mapping coordinates can be determined based on the target first direction coordinates and the target second direction coordinates.

[0114] Step S520 : determining target texture coordinates according to the candidate texture coordinates and the front-back floating perspective parameters.

[0115] In an exemplary embodiment of the present disclosure, after obtaining candidate texture coordinates through the above steps, target texture coordinates can be determined based on the candidate texture coordinates and the front-back floating perspective parameter. Specifically, the target texture coordinates can be obtained by multiplying the candidate texture coordinates and the front-back floating perspective parameter.

[0116] For example, the target texture coordinates = candidate texture coordinates (X, Y) * front and back floating perspective parameters.

[0117] It should be noted that the present disclosure does not impose any special limitation on the specific method of determining the target texture coordinates based on the candidate texture coordinates and the front-back floating perspective parameters.

[0118] Through the above steps S510 to S520, candidate mapping coordinates can be determined according to the target first direction coordinates and the target second direction coordinates, and target mapping coordinates can be determined according to the candidate mapping coordinates and the front and back floating perspective parameters.

In the first area, the front texture map is sampled using the target texture coordinates, and in the second area, the back texture map is sampled using the target texture coordinates. As shown in FIG. 6 , in the second area, sampling the back texture map using the target texture coordinates can include the following steps S610 to S630:

Specifically, the virtual object is a two-dimensional object in a two-dimensional space, and the virtual object has endpoints. The endpoints of the virtual object refer to the projection points of the edges of the virtual object in the two-dimensional space. For example, the virtual object is a virtual flag, and the projection points of the lower side of the virtual flag in the two-dimensional space can be used as the endpoints of the virtual object. The texture maps corresponding to the virtual object include a front texture map and a back texture map, wherein the front texture map is used to render the front of the virtual object, and the back texture map is used to render the back of the virtual object. During the curling process of the virtual object starting from the endpoints, different areas of the virtual object need to sample different texture maps.

[0122] For example, the virtual object is a virtual flag, which faces the virtual lens. During the curling process of the virtual flag, first, the entire virtual flag needs to apply the front texture map. As the curling proceeds, some areas of the virtual flag need to apply the back texture map.

[0123] In an exemplary embodiment of the present disclosure, the curling degree of the virtual object may be determined by the positions of the endpoints, and the first area for sampling the front texture map and the second area for sampling the back texture map may be determined according to the curling degree of the virtual object.

[0125] Step S620 , sampling the front texture map in the first area using the target map coordinates;

[0126] Step S630: In the second area, the back surface texture map is sampled using the target texture coordinates.

[0127] In an exemplary embodiment of the present disclosure, after determining the first and second regions during the warping process through the above steps, the front texture map can be sampled in the first region using the target mapping coordinates, and the back texture map can be sampled in the second region using the target mapping coordinates. Specifically, as the virtual object warps, the first and second regions change, i.e., the regions where the front and back texture maps are sampled using the target mapping coordinates change, thereby achieving a warped effect on the rendered virtual object.

[0128] For example, as shown in FIG7 , as the virtual object curls, the first area and the second area will change, so that the rendered virtual object achieves a curling effect.

[0129] It should be noted that the present disclosure does not impose any special limitation on the specific manner of sampling the front texture map or the back texture map by using the target mapping coordinates in the first area or the second area.

[0130] Through the above steps S610 to S630, during the curling process of the virtual object starting from the endpoint, the first area for sampling the front texture map and the second area for sampling the back texture map can be determined according to the position of the endpoint. In the first area, the front texture map is sampled through the target map coordinates, and in the second area, the back texture map is sampled through the target map coordinates.

[0131] In an exemplary embodiment of the present disclosure, the degree of the curling center angle is determined based on the positions of the endpoints and the initial position, the curling portion pixel value is determined based on the curling center angle, and the first area for sampling the front texture map and the second area for sampling the back texture map are determined based on the curling portion pixel value. As shown in Figure 8, determining the first area for sampling the front texture map and the second area for sampling the back texture map based on the curling portion pixel value may include the following steps S810-S820:

[0132] Step S810, determining the curling center angle according to the positions of the endpoints and the initial position;

[0133] In an exemplary embodiment of the present disclosure, after the positions of the endpoints are obtained through the above steps, the degree of the curling center angle can be determined based on the positions of the endpoints and the initial position. Specifically, the initial position is used to indicate the starting position of the curling, and a curling center can be determined by the initial position and the positions of the endpoints. The curling center angle can be formed by the curling center, the initial position, and the positions of the endpoints, and the degree of the curling center angle can be determined by the positions of the endpoints and the initial position. Specifically, the curling radius can be determined based on the positions or initial positions of the endpoints and the curling center, and the degree of the curling center angle can be determined based on the curling radius.

[0134] It should be noted that the present disclosure does not impose any particular limitation on the specific method of determining the degree of the curling center angle according to the positions of the endpoints and the initial position.

[0135] Step S820: determining the pixel value of the curled portion according to the curling center angle, and determining the first area for sampling the front texture map and the second area for sampling the back texture map according to the pixel value of the curled portion.

[0136] In an exemplary embodiment of the present disclosure, after obtaining the curl center angle degree through the above steps, the curl portion pixel value can be determined based on the curl center angle degree, and the first area for sampling the front texture map and the second area for sampling the back texture map can be determined based on the curl portion pixel value. Specifically, the curl portion pixel value can be used to indicate the height of the curl portion, and the curl portion pixel value can be used to determine the curl portion and the non-curled portion of the virtual object. The curl portion pixel value can be determined using a trigonometric function to determine the first area for sampling the front texture map and the second area for sampling the back texture map.

[0137] It should be noted that the present disclosure does not impose any special limitation on the specific method of determining the first area for sampling the front texture map and the second area for sampling the back texture map according to the pixel values ​​of the curled portion.

[0138] Through the above steps S810 to S820, the curling center angle degree can be determined according to the position of the endpoint and the initial position, the curling part pixel value can be determined according to the curling center angle degree, and the first area for sampling the front texture map and the second area for sampling the back texture map can be determined according to the curling part pixel value.

[0139] In an exemplary embodiment of the present disclosure, the curling arc length can be determined based on the position of the endpoints, the curling radius corresponding to the curling process can be obtained, and the curling center angle degree can be determined based on the curling arc length and the curling radius. Referring to FIG9 , determining the curling center angle degree based on the curling arc length and the curling radius can include the following steps S910 to S920:

[0140] Step S910, determining the curling arc length according to the positions of the endpoints, and obtaining the curling radius corresponding to the curling process;

[0141] In an exemplary embodiment of the present disclosure, after determining the positions of the endpoints through the above steps, the length of the curling arc can be determined based on the positions of the endpoints. Specifically, after obtaining the positions of the endpoints and the initial position, the curling center can be determined based on the positions of the endpoints and the initial position. A curling arc is constructed with the positions of the endpoints and the initial position as the two endpoints of the curling arc, and the arc length of the curling arc is calculated. Furthermore, the curling radius corresponding to the curling process can be obtained. Specifically, the curling radius can be the length from the curling center to the positions of the endpoints, or the curling radius can be the length from the curling center to the initial position.

[0142] Step S920: determining the curling center angle according to the curling arc length and the curling radius.

[0143] In an exemplary embodiment of the present disclosure, after obtaining the curling arc length and curling radius through the above steps, the curling center angle can be determined based on the curling arc length and curling radius. Specifically, the curling center angle can be calculated based on the arc length calculation formula.

[0144] Specifically, the arc length calculation formula is L = n × π × r / 180, where n is the curling center angle, r is the curling radius, and L is the curling arc length. After deduction, the curling center angle n = curling arc length * 180 / π / curling radius.

[0145] It should be noted that the present disclosure does not impose any particular limitation on the specific method of determining the curling center angle according to the curling arc length and the curling radius.

[0146] Through the above steps S910 to S920, the curling arc length can be determined according to the positions of the end points, the curling radius corresponding to the curling process can be obtained, and the curling center angle can be determined according to the curling arc length and the curling radius.

[0147] In an exemplary embodiment of the present disclosure, a first region for sampling the front texture map and a second region for sampling the back texture map are determined based on the pixel values ​​of the curled portion and the quadrant in which the endpoints are located. Specifically, the curling process corresponds to a curling center, and a coordinate system can be constructed around the curling center. This coordinate system has a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant. Specifically, this coordinate system is a coordinate system within a two-dimensional simulation plane.

[0148] As shown in Figure 10, n is the curling center angle, a is the initial position, b is the curling length position, y is the curling part pixel value, and r is the curling radius.

[0149] When the quadrant where the endpoint is located is the third quadrant, the pixel value of the curled part is less than one-fourth of the curled perimeter, and sin(n) = pixel value of the curled part / curled radius. Then the pixel value of the curled part = sin(n) * curled radius. That is, the curled part corresponding to -b < y ≤ a is the first region. In the first region, the front texture map can be sampled through the target texture coordinates, and the part where y < -b is not rendered;

[0150] When the quadrant where the endpoint is located is the fourth quadrant, the pixel value of the curled part is greater than one-fourth of the curled perimeter and less than one-half of the curled perimeter, and sin(180 - n) = pixel value of the curled part / curled radius. Then the pixel value of the curled part = sin(180 - n) * curled radius. That is, the curled part corresponding to -r < y ≤ -b is the first region. In addition, the uncurled part where y > a is also the first region. In the first region, the front texture map can be sampled through the target texture coordinates. The curled part beyond the pixel value of the curled part is the second region, that is, the curled part corresponding to -b < y ≤ a. In the second region, the back texture map can be sampled through the target texture coordinates, and the part where y < -r is not rendered;

[0151] When the quadrant where the endpoint is located is the first quadrant, the pixel value of the curled part is greater than one-half of the curled perimeter and less than three-fourths of the curled perimeter, and sin(n - 180) = pixel value of the curled part / curled radius. Then the pixel value of the curled part = sin(n - 180) * curled radius. That is, the curled part corresponding to a < y ≤ b is the second region. In the second region, the back texture map can be sampled through the target texture coordinates, and the part where y > b is not rendered;

[0152] When the quadrant where the endpoint is located is the second quadrant, the pixel value of the curled part is greater than three-fourths of the curled perimeter and less than the curled perimeter, and sin(n - 270) = pixel value of the curled part / curled radius. Then the pixel value of the curled part = sin(n - 270) * curled radius. That is, the curled part corresponding to b < y ≤ r is the second region. In the second region, the back texture map can be sampled through the target texture coordinates. The part where y > r is the first region, and in the first region, the front texture map can be sampled through the target texture coordinates.
