[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.
[0027] The embodiments of the present application provide an animation generation method, apparatus, computer device, and computer-readable storage medium. The animation generation apparatus can be integrated into a computer device, which can be a server or a terminal.
[0028] The terminal may include a mobile phone, a wearable smart device, a tablet computer, a laptop computer, a personal computer (PC), and a vehicle-mounted computer.
[0029] Among them, the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides 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, content delivery networks (CDNs), as well as big data and artificial intelligence platforms.
[0030] It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.
[0031] This embodiment will be described from the perspective of an animation generating apparatus. The animation generating apparatus may be integrated into a computer device, which may be a server or a terminal.
[0032] An animation generation method provided in an embodiment of the present application is as follows: Figure 1 As shown, the specific process of the animation generation method can be as follows:
[0033] 101. Obtain animation parameters corresponding to a target patch, where the animation parameters include division parameters of a target shape pattern on the target patch and display change control parameters corresponding to the target shape pattern.
[0034] The target patch may be a patch model, which may include a mesh. The target patch may also be one of the patches on a model composed of multiple patches. The target patch may be a rectangle, a triangle or other shapes.
[0035] Among them, the target shape pattern can be a positive direction, a circle or other shapes, and there can be one or more target shape patterns. The division parameter can be used to divide the target surface into one or more blocks, each block is used to present a target shape pattern. If there is only one target shape pattern, then the blocks of the target surface present the same shape pattern. If there are multiple target shape patterns, then the blocks of the target surface can present different shape patterns. The display change control parameter is used to control the change of the target shape pattern in each block, such as size change, color change, etc. The display change control parameter can be used to control the user's target shape pattern to continuously diffuse outward in the block over time, or to continuously shrink inward over time.
[0036] 102. Divide the target surface into at least one block according to a division parameter.
[0037] Since the partition parameter may indicate how to partition the target patch into a plurality of blocks, the target patch may be partitioned into at least one block according to the partition parameter.
[0038] For example, the division parameter may include the number of blocks, and the target surface can be divided into at least one block according to the number of blocks; for another example, the division parameter may be the distribution density of the target shape pattern in the horizontal and vertical directions, and the surface model can be divided into at least one block according to the distribution density; the division parameter can also indicate the position of each block in the target surface, and the target surface can be divided into multiple blocks based on the division parameter. Whether the sizes of the multiple blocks obtained by division are the same or different depends on the division parameter. If the sizes of the blocks obtained by division can be made different by setting the division parameter.
[0039] It can be understood that dividing the target surface into at least one block does not mean splitting the target surface into multiple surfaces. The target surface remains one surface before and after the division. Dividing the target surface into at least one block means distinguishing different areas on the target surface.
[0040] In one embodiment, the target patch may be divided into a plurality of blocks by processing the texture coordinates. That is, in one embodiment, the step of “dividing the target patch into at least one block according to the division parameter” may include:
[0041] Expanding the texture coordinates of each pixel point of the target patch according to the division parameter to obtain the first texture coordinates;
[0042] De-integer the first texture coordinates to obtain second texture coordinates corresponding to each pixel point of the target surface;
[0043] The target surface is divided into a plurality of blocks according to the second texture coordinates, wherein the second texture coordinates of the pixels in each block are distributed within a preset coordinate range.
[0044] Among them, the pixel is the smallest unit of image display, the division parameter can be the number of blocks or the distribution density, the target surface is a surface model, and the texture coordinates corresponding to each pixel point of the target surface are distributed between (0,0) and (1,1). The block density of the surface model in the horizontal and vertical directions can be determined according to the division parameter, and the texture coordinates of each pixel point on the target surface are multiplied according to the block density to expand the texture coordinates to obtain the first texture coordinates.
[0045] Assuming the block density is 2, multiply u and v in the texture coordinates (u, v) of each pixel on the target patch by 2 to obtain the first texture coordinate (2u, 2v).
[0046] Then, remove the integer in the first texture coordinate and retain the decimal part in the first texture coordinate to obtain the second texture coordinate. For example, the first texture coordinate (1.5, 1.5) is decremented to obtain the second texture coordinate (0.5, 0.5). For the first texture coordinate (1.5, 1.5), the first texture coordinate (2.5, 2.5) is decremented to obtain the second texture coordinate (0.5, 0.5). Therefore, by decrementing the first texture coordinate, an independent texture coordinate with linear horizontal and vertical changes can be mapped to each pixel point of the block.
[0047] The target surface can be divided into multiple blocks according to the second texture coordinates, and the second texture coordinates of the pixels in each block meet the preset coordinate range, that is, the second texture coordinates of the pixels in each block are distributed between (0,0) and (1,1).
[0048] 103. Calculate the target distance between each pixel point in each block and the center point of the block.
[0049] Among them, the block center point can be a point located at the center of the block, and the target distance can be the distance between the texture coordinates of the pixel point and the block center point, or the distance between the pixel point and the pixel coordinates of the block center point. It can be selected according to specific needs and is not limited here.
[0050] For example, for each block, the distance between each pixel point of the block and the center point of the block is calculated based on the texture coordinates of the center point of the block and the texture coordinates corresponding to each pixel point in the block to obtain the target distance; for another example, for each block, the distance between each pixel point of the block and the center point of the block is calculated based on the pixel coordinates of the center point of the block and the pixel coordinates of each pixel point in the block to obtain the target distance.
[0051] Alternatively, if the target shape pattern is a rectangle, the target distance may be the maximum distance between the pixel point and the block center point in the u direction and the v direction. That is, in one embodiment, the step of "calculating the target distance between each pixel point in each block and the block center point" may include:
[0052] For each block, calculating a first distance in a first direction and a second distance in a second direction between each pixel point of the block and the center point of the block based on the texture coordinates of each pixel point of the block and the texture coordinates of the center point of the block;
[0053] A target distance between each pixel point of the block and the center point of the block is determined according to the first distance and the second distance.
[0054] Among them, the first direction may refer to the u direction, and the second direction may refer to the v direction. For each block, according to the u component of the texture coordinates of the block center point and the u component of the texture coordinates corresponding to each pixel point in the block, the distance between each pixel point in the block and the center point of the block in the u direction is calculated to obtain the first distance; according to the v component of the texture coordinates of the center point of the block and the v component of the texture coordinates corresponding to each pixel point in the block, the distance between each pixel point in the block and the center point of the block in the v direction is calculated to obtain the second distance.
[0055] The maximum value of the first distance and the second distance is determined as the target distance, so that a first area with a rectangular shape can be determined in the block based on the target distance.
[0056] 104. For each block, determine a first area covered by the target shape pattern and a second area not covered by the target shape pattern in the block at different times based on the display change control parameter and the target distance of each pixel point in the block.
[0057] The display control parameters can be used to control the change in the size of the target shape pattern in the same block over time, and / or to control the difference between the target shape patterns in different blocks. Therefore, based on the display change control parameters and the target distance of each pixel point in the block, the first area covered by the target shape pattern at different times can be mapped out in the block, and the area outside the first area in the block can be determined as the second area not covered by the target shape pattern.
[0058] For example, the display change control parameter may include a change speed, which is the speed at which the size of the target shape pattern changes over time. Size information of the target shape pattern at different moments can be determined based on the change speed and time. That is, in one example, the display change control parameter includes the change speed. The step of "determining, for each block, the first area covered by the target shape pattern in the block at different moments based on the display change control parameter and the target distance between pixels in the block" may include:
[0059] For each block, calculate the size information of the target shape pattern at different times according to the change speed;
[0060] According to the target distance corresponding to each pixel point in the block and the size information of the target shape pattern at different times, the first area covered at different times is determined in each block.
[0061] For example, the relationship between the size of the target shape pattern and the time and change speed can be pre-set, and the size information of the target shape pattern at different times can be calculated based on the change speed and time. For example, when the animation starts playing, the size of the target shape pattern can be the largest, and then the size gradually becomes smaller with time, or when the animation starts playing, the size of the target shape pattern can be the smallest, and then the size gradually becomes larger with time, and the target shape pattern can change cyclically, for example, first changing from the largest to the smallest, and then changing from the largest to the smallest again, and continuously cycling.
[0062] For example, the target shape pattern is a grid. The size of the grid changes from small to large over time, and then changes from small to small again, and the cycle continues. The schematic diagram of the change effect of the grid in a block of the target patch can be shown as follows: Figure 2 shown.
[0063] For different shape patterns, the corresponding size information is different. For example, if the target shape pattern is a circle, the size information may be the radius or diameter; if the target shape pattern is a rectangle, the size information may be the side length of the rectangle.
[0064] For each block, based on the size information of the target shape pattern at different times and the target distance corresponding to each pixel point in the block, determine whether the pixel point is located in the first area covered by the target shape pattern, and determine the first area in the block based on the pixel points determined to be located in the first area.
[0065] For each block, a first area covered by the target shape pattern in the block is determined. Specifically, a boundary condition of the target shape pattern in the block can be determined based on size information of the target shape pattern, and the first area is determined from the block based on the boundary condition. That is, the step of "determining the first area covered at different times in each block based on the target distance corresponding to each pixel in the block and the size information of the target shape pattern at different times" includes:
[0066] For each moment, determining the boundary conditions of the target shape pattern in the block according to the size information of the target shape pattern at the moment;
[0067] According to the boundary conditions corresponding to the target shape pattern at the time, the pixel points whose target distance meets the boundary conditions are determined in the block to obtain the first areas corresponding to different time periods.
[0068] For the first block in the block, the boundary condition of the target shape pattern in the first block can be determined for each moment based on the size information of the target shape pattern at that moment. The boundary condition can indicate a distance threshold of the target distance of the pixel points located in the first area. The pixel points whose target distance meets the boundary condition are determined in the block to obtain the first area of the target shape pattern in the first block at that moment. The first area of the target shape pattern in the first block at each moment can be obtained in the same way.
[0069] The same process may be performed on other blocks to obtain the first area of the target shape pattern in each block at different times.
[0070] Exemplarily, the target shape pattern is a circle, the size information is the radius of the circle, the target distance of the pixel points in the block can be the distance between the pixel points and the center point of the block, the boundary condition can be that the target distance is equal to the radius, or that the difference between the target distance and the radius is equal to zero. For each block, the pixel points whose target distance meets the boundary conditions can be determined in the block based on the boundary conditions at different times, and then the first area can be obtained.
[0071] In another example, the target shape pattern is a rectangle, and the size information is the side length of the rectangle. The target distance of the pixel points in the block can be twice the maximum distance between the pixel point and the center point of the block in the u direction and the v direction. The boundary condition can be that the target distance is equal to the side length of the rectangle, or that the difference between the target distance and the side length of the rectangle is equal to zero. For each block, the pixel points whose target distance meets the boundary conditions can be determined in the block based on the boundary conditions at different times, and then the first area can be obtained.
[0072] Optionally, a border width of the target shape pattern may be set, and boundary conditions may be set based on the border width to adjust the line width of the target shape pattern displayed in the block. That is, in one example, the display change control parameter includes the border width of the target shape pattern, and the boundary conditions include a first boundary condition and a second boundary condition. The step of "determining the boundary condition of the target shape pattern in the block based on the size information of the target shape pattern at each moment" may include:
[0073] For each moment, determining a first boundary condition of the target shape pattern in the block according to size information of the target shape pattern at the moment;
[0074] The second boundary conditions of the target shape pattern in each block at different times are determined according to the border width.
[0075] For the first block in the block, the boundary condition can indicate the distance range of the target distance of the pixel points located in the first area, the first boundary condition can indicate one of the minimum threshold and the maximum threshold of the target distance of the pixel points located in the first area, and the second boundary condition can indicate the other. The pixel points whose target distance meets the boundary condition are determined in the block, and the first area of the target shape pattern in the first block at that moment is obtained. The first area of the target shape pattern in the first block at each moment can be obtained in the same way.
[0076] The same process may be performed on other blocks to obtain the first area of the target shape pattern in each block at different times.
[0077] Exemplarily, the target shape pattern is a circle, the size information is the radius of the circle, the target distance of the pixel point in the block can be the distance between the pixel point and the center point of the block, the first boundary condition can be that the target distance is equal to the radius, or that the difference between the target distance and the radius is greater than or equal to zero, the second boundary condition can be that the target distance is less than or equal to the radius + the border width, or that the difference between the target distance and the radius is less than or equal to the border width. For each block, the pixel points whose target distance meets the boundary conditions can be determined in the block according to the boundary conditions at different times, and then the first area can be obtained.
[0078] In another example, the target shape pattern is a rectangle, and the size information is the side length of the rectangle. The target distance of the pixel points in the block can be twice the maximum distance between the pixel point and the center point of the block in the u direction and the v direction. The first boundary condition can be that the target distance is greater than or equal to the side length of the rectangle, or that the difference between the target distance and the side length of the rectangle is greater than or equal to zero. The second boundary condition can be that the target distance is less than or equal to the side length of the rectangle + the border width, or that the difference between the target distance and the side length of the rectangle is less than or equal to the border width. For each block, the pixel points whose target distance meets the boundary conditions can be determined in the block according to the boundary conditions at different times, and then the first area can be obtained. The difference between the first areas determined by different border widths can be as follows. Figure 3 As shown, Figure 3 The middle is the first area determined based on different border widths. The larger the border width, the thicker the rectangular lines.
[0079] In one embodiment, the first region may be determined from each block by using a function smoothstep().
[0080] At the same moment, the sizes of the target shape patterns in different blocks can be the same or different. If the sizes of the target shape patterns in two blocks are different at the same moment, they can be adjusted by the adjustment parameters corresponding to the blocks. For example, in one embodiment, each block can correspond to a block phase, and the block phase is used to control the size difference of the target shape patterns in different blocks. For example, the target shape pattern corresponds to preset size information. According to the block phase corresponding to each block, the size of the target shape pattern in the block is adjusted so that the size of the target shape pattern in different blocks is different. Exemplarily, at the same moment, the effect of the size of the target shape patterns in different blocks can be as follows. Figure 4 shown.
[0081] Optionally, the size information of the target shape pattern in each block may be calculated based on the change rate, and then the size information may be adjusted based on the block phase. That is, in one embodiment, the step of "calculating the size information of the target shape pattern at different times based on the change rate for each block" includes:
[0082] Determine the initial size information of the target shape pattern at different times based on the product of the change speed and different times;
[0083] For each block, performing differential adjustment processing on the initial size information based on the block phase of the block to obtain adjusted size information of the target shape pattern in the block at different times, wherein the block phases of at least two blocks are different;
[0084] The size information of the target shape pattern in the block at different times is obtained based on the adjusted size information.
[0085] For example, the change speed and the different moments may be multiplied to obtain the initial size information of the target shape pattern at different moments, where the different moments refer to the playing time of the target animation.
[0086] Each block corresponds to a block phase, and the initial size information is differentially adjusted according to the block phase. The initial size information and the block phase may be multiplied to obtain the adjusted size information, or the initial size information and the block phase may be added to obtain the adjusted size information.
[0087] The block phase determines the size of the target shape pattern initially displayed in the block. The difference in block phase between blocks determines the size difference of the target shape pattern displayed between blocks at the same time. In one embodiment, the display change control parameter may further include a phase difference adjustment parameter for adjusting the block phase difference between blocks. The size difference of the target shape pattern displayed between blocks at the same time may be adjusted by the block phase difference. That is, the display change control parameter includes the phase difference adjustment parameter. The step of "for each block, performing difference adjustment processing on the initial size information based on the block phase of the block to obtain adjusted size information of the target shape pattern in the block at different times" may include:
[0088] Adjusting the block phase corresponding to each block according to the phase difference adjustment parameter to obtain an adjusted block phase corresponding to each block;
[0089] The initial size information of each block at different times is adjusted according to the adjusted block phase corresponding to each block, so as to obtain the adjusted size information of the target shape pattern of each block at different times.
[0090] For example, for each block, the phase difference adjustment parameter and the block phase corresponding to the block can be multiplied to adjust the block phase to obtain the adjusted block phase corresponding to the block. By adjusting the block phase through the phase difference adjustment parameter, the phase difference between the blocks can be adjusted, for example, the phase difference between the blocks can be increased or reduced.
[0091] The initial size information corresponding to each block at different times is resized according to the adjusted block phase corresponding to each block. Specifically, the initial size information and the adjusted block phase may be multiplied to obtain the adjusted size information, or the initial size information and the adjusted block phase may be added to obtain the adjusted size information.
[0092] Since the block phases of at least two blocks are different, after the initial size information is adjusted based on the block phases, the adjusted size information corresponding to at least two blocks is different, which can increase the flexibility of changing the target shape pattern in each block.
[0093] After obtaining the adjusted size information, the adjusted size information of the target shape pattern in the block at different times may be used as the size information of the target shape pattern in the block at different times.
[0094] Optionally, the decimal part of the adjusted size information may be retained and used as the size information of the target shape pattern in the block at different times. Assuming that the adjusted size information is 3.2, the decimal part is retained, and the size information obtained is 0.2.
[0095] Alternatively, for each block, the adjusted size information of the target shape at different times is mapped to a fixed value range to obtain size information of the target shape pattern in the block at different times. That is, in one embodiment, the step of "obtaining size information of the target shape pattern in the block at different times based on the adjusted size information" includes:
[0096] The adjusted size information of the target shape pattern in the block at different times is mapped to a fixed value range to obtain the size information of the target shape pattern in the block at different times. The size information changes cyclically within the fixed value range over time.
[0097] Among them, the fixed numerical range can be related to the texture coordinate range or pixel coordinate range of the block. If the block is rectangular, the target shape pattern is circular, and the size information is the radius of the circle, then the fixed numerical range is 0 to 1 / 2 of the minimum side length of the block. If the size information is the diameter of the circle, then the fixed numerical range is 0 to the minimum side length of the block.
[0098] If the target shape pattern is a rectangle and the size information is the side length of the rectangle, the fixed value range can be 0 to the minimum side length of the block. If the texture coordinates of each block are mapped to between (0,0) and (1,1) when the target surface is divided into multiple blocks, then the fixed value range can be [0,1].
[0099] Specifically, for each block, the adjusted size information of the target shape pattern in the block at different times is mapped to a fixed numerical range using the objective function, thereby obtaining the size information of the target shape pattern in the block at different times. If the fixed numerical range is [0, 1], the objective function can map the adjusted size information that changes over time to size information that changes cyclically from 0 to 1 and then back to 0 to 1. The objective function can be a function such as frac().
[0100] The block phase corresponding to each block can be manually preset, or the display change control parameter includes the block phase corresponding to each block. The block phase corresponding to each block can be determined according to the display change control parameter. By controlling the block phase corresponding to the block by the display change control parameter, the difference between blocks can be flexibly set.
[0101] Optionally, a random number may be generated for each block as the block phase, or the block phase may be obtained by mapping according to the texture coordinates of the block. That is, in one embodiment, before the step of "for each block, performing differential adjustment processing on the initial size information based on the block phase of the block to obtain adjusted size information of the target shape pattern in the block at different times", the method further includes:
[0102] Rounding the first texture coordinates of the pixel points of each block to obtain the third texture coordinates of the pixel points of each block;
[0103] A block phase corresponding to each block is generated according to the third texture coordinates of the pixel points of each block.
[0104] The rounding process may be to retain the integers of the coordinate components in the first texture coordinates. For example, if the coordinate component is 1.2, it will be 1 after rounding. For example, if the coordinate component is 2.3, it will be 2 after rounding.
[0105] Since the first texture coordinate is obtained by multiplying the texture coordinates of each pixel on the target surface according to the distribution density of the block patch model in the horizontal and vertical directions, for example, the block density in the horizontal and vertical directions of the target surface is 2, then the u and v in the texture coordinates (u, v) of each pixel on the target surface are multiplied by 2 respectively to obtain the first texture coordinate (2u, 2v). Therefore, the third texture coordinates corresponding to the pixels in the same block are the same, for example, (1,1), (2,2) or (3,3).
[0106] The third texture coordinate corresponding to each block may be mapped to a random number to obtain the block phase corresponding to each block.
[0107] Optionally, a mapping algorithm may be configured to map the third texture coordinate to a block phase to achieve a customized variation effect.
[0108] 105. Control the first area and the second area in the same block to display with different display parameters to generate a target animation.
[0109] The display parameters of the first area and the second area in the same block are different, so the display effects of the first area and the second area are different. The display difference between the first area and the second area visually presents a target shape pattern displayed in the block. Since the first area changes over time, the animation effect is that the target shape pattern changes continuously over time.
[0110] The different display parameters of the first area and the second area may include different textures, different transparencies and / or different colors. The different display parameters of the first area and the second area may be pre-set in the program, or may be configured according to the required effects, such as setting the corresponding parameters in the display change control parameters to control the display effects of the first area and the second area.
[0111] For different colors, different areas can be preset to display different colors. For example, as shown in the figure, the first area can be black and the second area can be white. The colors of the first area and the second area can also be determined by display change control parameters. That is, in one embodiment, the display change control parameters include the background color of the target surface and the border color of the target shape pattern on the target surface. The step of "controlling the first area and the second area in the same block to display with different display parameters to generate the target animation" may include:
[0112] The first area is mapped to a border color, and the second area is mapped to a background color to generate a target animation.
[0113] For example, the display change control parameters may include the background color of the target surface and the border color of the target shape pattern. The background color of the target surface is the color of the second area, and the border color of the target shape pattern is the color of the first area. According to the display change parameters, the first area is mapped to the border color, and the second area is mapped to the background color to generate the target animation.
[0114] The embodiments of the present application can be used to create dynamic lighting effects or other special effects in a virtual scene.
[0115] The embodiment of the present application renders an animation in which at least one target shape pattern changes continuously over time without the need for mapping, such as a diffusion animation or a contraction animation of the target shape pattern. Since the animation can be rendered without the need for mapping, the process of texture mapping required for animation production and the process of sampling the texture mapping are reduced, which can reduce the difficulty of animation production and the computer resources occupied by rendering the animation.
[0116] If an animation effect is generated by means of animation sequence frames, when it is necessary to render an animation in which multiple target shape patterns change continuously over time, it is necessary to produce a corresponding number of facets based on the number of target shape patterns, and set a corresponding texture map for each facet. However, the embodiment of the present application only requires one facet model to generate and render an animation in which multiple target shape patterns change continuously over time, which can further improve the animation production effect.
[0117] In addition, the embodiment of the present application can flexibly control the animation effect by displaying change control parameters, thereby improving the animation change effect.
[0118] As can be seen from the above, the embodiment of the present application obtains animation parameters corresponding to the target surface, and the animation parameters include division parameters of the target surface for the target shape pattern and display change control parameters corresponding to the target shape pattern; divides the target surface into at least one block according to the division parameters; calculates the target distance between each pixel point of each block and the center point of the block; for each block, based on the display change control parameters and the target distance of each pixel point of the block, determines the first area covered by the target shape pattern in the block at different times, and the second area not covered by the target shape pattern; controls the first area and the second area in the same block to be displayed with different display parameters, generates the target animation, and realizes the generation of animation effects without using texture mapping, and since there is no need to pre-make texture mapping, the difficulty of generating animation can be reduced, and no texture sampling is required, which can reduce the computer resources occupied by rendering animation.
[0119] Based on the above embodiment, the following description will be made by taking the target shape pattern as a grid and the animation effect as the grid spreading over time as an example.
[0120] Artists can load the corresponding shader into the model material. The shader contains an algorithm for implementing the animation effect of the grid diffusing over time. They can set the block density and display change control parameters through the provided panel or other means. The display change control parameters may include change speed, phase difference adjustment parameters, border width, border color, and background color.
[0121] After receiving the block density and display change control parameters entered by the artist, the terminal processes the texture coordinates based on the algorithm in the shader to divide the target patch into multiple blocks. Specifically, the block density multiplies the texture coordinates of each pixel on the target patch to expand the texture coordinates and obtain the first texture coordinates. Assuming the block density is 2, the u and v of the texture coordinates (u, v) of each pixel on the target patch are multiplied by 2 to obtain the first texture coordinates (2u, 2v).
[0122] Then, remove the integer in the first texture coordinate and retain the decimal part in the first texture coordinate to obtain the second texture coordinate. For example, the first texture coordinate (1.5, 1.5) is decremented to obtain the second texture coordinate (0.5, 0.5), the first texture coordinate (2.5, 2.5) is decremented to obtain the second texture coordinate (0.5, 0.5), and the first texture coordinate (2.5, 2.5) is decremented to obtain the second texture coordinate (0.5, 0.5). Therefore, by decrementing the first texture coordinate, an independent texture coordinate with linear horizontal and vertical changes can be mapped to each pixel point of each block.
[0123] The target surface can be divided into multiple blocks according to the second texture coordinates, and the second texture coordinates of the pixels in each block meet the preset coordinate range, that is, the second texture coordinates of the pixels in each block are distributed between (0,0) and (1,1).
[0124] The first texture coordinates are rounded to the integer of each coordinate component, obtaining the third texture coordinates. For example, a coordinate component of 1.2 is rounded to 1, and a coordinate component of 2.3 is rounded to 2. Pixels in the same block have the same third texture coordinates, such as (1,1), (2,2), or (3,3).
[0125] The third texture coordinate corresponding to each block may be mapped to a random number to obtain the block phase corresponding to each block.
[0126] For each block, the distance between each pixel in the block and the block center is calculated based on the texture coordinates of the block center and the texture coordinates corresponding to each pixel in the block. The distance is multiplied by 2 to obtain the target distance.
[0127] The size information of a square can be the side length of the square. The relationship between the side length of the square and time can be sideLength = frac(changeSpeed × Time + rand × randAmount), where changeSpeed is the change speed, Time is the time, rand is the block phase corresponding to the block, and randAmount is the phase difference adjustment parameter. The function frac() can realize the side length from 0 to 1, and then from 0 to 1 again, in a continuous cycle. Based on the relationship between the side length of the square and time, the side length of the square at different times can be determined.
[0128] For each block, according to the target distance of each pixel point in the block, the side length of the corresponding square and the border width, a first area that is continuously expanding can be mapped from each square.
[0129] The first area and the second area are mapped to different colors to generate a target animation.
