[0002] In order to simulate dynamic scenes in games, special effects animation is usually chosen to achieve this. To achieve dynamic effects through special effects animation, it is necessary to call relevant models and use a large number of particles. Moreover, as the dynamic effects continue to change, multiple special effects scenes need to be produced to achieve the change in style.

[0003] During the rendering process, as the number of special effects images increases, the number of computing instances required by the terminal device also increases. Rendering in this way places extremely high requirements on the performance of the terminal device.

[0086] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work falls within the scope of protection of the present application.

[0087] Research has found that in order to simulate scenes with dynamic effects in games, special effects animation is usually chosen to achieve this. To simulate dynamic effects through special effects animation, it is necessary to call related models and use a large number of particles. Moreover, as the dynamic effects continue to change, multiple frames of special effects scenes need to be produced to achieve changes in style. During the rendering process, as the number of special effects scenes increases, the number of computing instances required by the terminal device will also increase. When rendering in this way, the performance requirements for the terminal device are extremely high, and due to the large number of special effects scenes, the time required for the terminal device to render will also be longer, resulting in a lower rendering rate.

[0088] Based on this, an embodiment of the present application provides a model rendering method with dynamic effects, which can render a target model with dynamic effects by changing the transparency parameters carried by the target material ball over time. In this way, while ensuring the authenticity of the rendered simulated object, it can reduce the number of calculation examples required in the rendering process of the terminal device and improve the rendering efficiency of the game screen.

[0089] See also Figure 1 , Figure 1 This is a flow chart of a model rendering method for dynamic effects provided by an embodiment of the present application. Figure 1 As shown in , the model rendering method of dynamic effects provided by the embodiment of the present application includes:

[0090] S101. Obtain an initial transparency parameter of an initial material ball according to material information of a target model.

[0091] S102 : Based on the pixel parameters of the texture map, adjust the initial transparency parameter of the initial material ball to obtain a target material ball whose transparency parameter changes with time.

[0092] S103: Utilize the target material ball to render the target model to obtain a dynamic effect of the target model.

[0093] The embodiment of the present application provides a model rendering method with dynamic effects. When the target model displayed in the game scene has a dynamic effect, the initial transparency parameter of the material ball used to render the target model is obtained based on the material information of the target model itself when it is displayed. In order to render the target model with dynamic effects, the initial transparency parameter in the initial material ball is adjusted by a dynamic texture map used to render the surface texture of the target model with dynamic effects. Since the transparency parameter of the dynamic texture map changes with time, the transparency parameter carried by the adjusted target material ball can also change with time, thereby simulating the dynamic effect of the target model. In this way, a target model with dynamic effects can be simulated without the need for additional animation special effects. In this way, the computational cost required for the terminal device to render the special effects screen can be reduced, thereby improving the rendering efficiency of the terminal device.

[0094] If you want to simulate a target model with realistic effects in the game, you need to simulate the material of the target model; here, the material refers to the real properties of the target object, such as the color information, reflective effect, transparency information, etc.

[0095] The material ball is a VR parameter file, which includes the color parameters, reflective effects, transparency parameters and other physical attribute parameters of the target model mentioned above, as well as various static maps, such as texture maps, Matcap (Material Capture) maps and normal maps, etc. Therefore, the actual effect that the material ball can render depends on the physical attribute parameters and various mapping information it includes.

[0096] In step S101 , the initial transparency parameter of the initial material ball used to render the target model may be obtained in advance based on the material information of the target model displayed in the game scene.

[0097] Here, while obtaining the initial transparency parameter, other initial parameters in the initial material ball may be set with reference to the material information of the target model, including initial color parameters, reflection effect parameters, and initial transparency parameters.

[0098] For example, here we take the target model as the "moon". In order to make the presented "moon" more beautiful and fit the display effect of the real "moon" in the game, the "moon" is usually made translucent, that is, the outer contour of the "moon" is an opaque boundary, and the interior of the "moon" is completely transparent. At this time, the Fresnel algorithm can be used to produce a translucent material ball with a "solid outside and hollow inside", that is, the outer contour of the "moon" is opaque, and gradually becomes transparent from the outer contour of the "moon" to the center of the "moon".

[0099] Since the present application renders a target model with a dynamic effect by changing the transparency parameter over time, other parameters (for example, color parameters) are not changed during the transparency adjustment process. Other parameters can be directly added to the material ball without changing during the transparency adjustment process. Therefore, in the subsequent process, only the transparency adjustment process is explained, and the process of adding other parameters will not be repeated.

[0100] The above process can only render a statically displayed target model. However, in some game scenes, in order to improve the realism of the game screen, there are usually some dynamic effects on the target model, such as "smoke" floating on the surface of the "moon".

[0101] In step S102, in order to obtain a target model with dynamic effects, the pixel parameters of the texture map are used to adjust the initial transparency parameters of the initial material ball, so that the transparency parameters in the adjusted material ball change with time; in this way, the dynamic effect can be simulated by changing the transparency parameters with time, and there is no need to produce special effects animation to achieve the dynamic effect.

[0102] The texture map includes a dynamic texture map in which pixel parameters change over time; the dynamic texture map is used to render a dynamic effect on the surface texture of the target model.

[0103] Furthermore, for a target model, the surface texture of the target model not only includes dynamic effects, but also may include some fixed predetermined patterns (for example, foreground patterns and background patterns); however, if the target model is in a completely transparent state, no pattern can be displayed on the surface texture of the target model. Only when the surface texture of the target model is in a non-transparent state such as opaque or partially opaque, can the corresponding pattern be displayed in the non-transparent area.

[0104] Therefore, in order to enable the corresponding pattern to be displayed on the surface texture of the rendered target model, the initial transparency of the initial material ball used to render the target model can be adjusted according to the first pixel parameter of the static texture map to ensure that the static texture map appears non-transparent in the corresponding display area in the target model.

[0105] In one embodiment, the texture map further comprises a static texture map; see Figure 2 , Figure 2 This is a schematic diagram of a transparency adjustment process provided by an embodiment of the present application. Figure 2 As shown, step S102 includes:

[0106] Step S1021: Using the first pixel parameter of the static texture map, adjust the initial transparency parameter of the initial material ball to obtain a first material ball with a first transparency parameter.

[0107] In this step, the initial transparency parameter of the initial material ball is adjusted step by step using the static texture map and the dynamic texture map respectively; specifically, the initial transparency parameter of the initial material ball is adjusted using the first pixel parameter carried by the static texture map; here, for a static texture map, it is composed of multiple polygonal grids, each polygonal grid is equivalent to a pixel position (point) of the static texture map, and each pixel position has a first pixel value. When adjusting the initial transparency parameter, the first pixel value of each pixel position can be used to adjust the transparency value of the corresponding pixel position in the initial material ball; and then, after the adjustment, the first material ball with the first transparency parameter is obtained.

[0108] Since transparency is actually a value between 0 and 1, changing this "value" so that it is within the range of 0 to 1 and not 0 can change the transparency of each pixel position, and can make the originally completely transparent pixel position become opaque or semi-transparent.

[0109] The first pixel parameter of the static texture map, for example, the pixel value of any color channel, or the transparency parameter carried by itself, or the grayscale pixel value, etc., are all "numerical values" in the range of 0 to 1. Therefore, the first pixel parameter here can include color parameters and transparency parameters (Alpha, A); color parameters can include color parameters of the three color channels of red (Red, R), green (Green, G), and blue (Blue, B) and grayscale pixel parameters, etc.

[0110] In one embodiment, the static texture map includes a foreground pattern map; step S1021 includes: determining the transparent area and the non-transparent area in the initial material ball based on the surface texture of the target model; using the first pixel parameter of the foreground pattern map, adjusting the initial transparency parameter of the non-transparent area to obtain a first material ball with a first transparency parameter.

[0111] The foreground pattern map is used to render the foreground pattern in the surface texture of the target model, that is, by "adding" the foreground pattern map to the material ball, the foreground pattern map can be displayed on the surface of the target model rendered by the material ball.

[0112] In this step, for the target model, there are transparent areas and non-transparent areas in its surface texture, that is, no pattern needs to be displayed in the transparent area of ​​the target model surface texture; it is sufficient to ensure that the foreground pattern map can be displayed in the non-transparent area. Therefore, in order to reduce part of the data processing amount, it is only necessary to use the foreground pattern map to adjust the initial transparency parameters of the non-transparent area in the initial material ball; specifically, according to the surface texture when the target model is displayed, the transparent area and the non-transparent area in the initial material ball are determined; for the determined non-transparent area, the first pixel parameter of the foreground pattern map (for example, the pixel value of any color channel, or the carried transparency parameter, or the grayscale pixel value, etc.) is used to adjust the initial transparency parameter of the non-transparent area in the initial material ball through corresponding operations to obtain a first material ball with a first transparency parameter. Here, the corresponding operations include addition, subtraction, OR, XOR, and inversion operations.

[0113] For the determined transparent area, in order to further reduce the amount of calculation in the rendering process, for the transparent area, the preset transparency parameters can be directly used to adjust the initial transparency parameters of each pixel in the transparent area by assignment.

[0114] Corresponding to the above embodiment, it is assumed that the pattern displayed on the "moon" is "leaves", and the initial material ball used to render the "moon" is a translucent material ball that is "solid outside and hollow inside" (the rendered "moon" gradually changes from a completely opaque state to a completely transparent state from the outer contour to the center). The current central area of ​​the "moon" is completely transparent. In this completely transparent state, the "leaves" located in the central area cannot be displayed. Therefore, at this time, it is necessary to use the first pixel parameter of the foreground pattern map corresponding to the "leaves" to adjust the initial transparency parameter of each pixel position at the position of the "leaves" in the initial material ball, so that the transparency of the pixel position at the position of the "leaves" is not 0, that is, the pixel position is in a non-transparent state.

[0115] In order to make the target model have a more realistic effect, the outer circle boundary contour of the surface texture of the target model can be processed into a model with a multi-level gradient effect through multiple synthesis processes.

[0116] In one embodiment, the adjusting the initial transparency parameter of the initial material ball using the first pixel parameter of the foreground pattern map to obtain the first material ball having the first transparency parameter includes:

[0117] Step a: using the first pixel parameter of the foreground pattern map, adjusting the initial transparency parameter in the non-transparent area to obtain a second material ball with a second transparency parameter.

[0118] In this step, the initial transparency parameter in the non-transparent area of ​​the initial material ball is adjusted using the foreground pattern map to obtain a second material ball with a second transparency parameter; at this time, the target model is rendered using the second material ball to obtain a target model with a foreground pattern map displayed on the surface.

[0119] Step b: using the first transparency difference between the initial transparency parameter and the second transparency parameter at each pixel position, synthesizing the initial material ball and the second material ball to obtain a third material ball with a third transparency parameter.

[0120] In this step, after obtaining the second material ball, the first transparency difference between the initial transparency value of each pixel position in the initial transparency parameter and the second transparency value of each pixel position in the second transparency parameter is calculated, and the initial material ball and the second material ball are synthesized using the first transparency difference at each pixel position to obtain a third material ball with a third transparency parameter; at this time, the target model is rendered using the third material ball to obtain a target model with a first gradient effect on the boundary and without displaying the foreground pattern map.

[0121] Here, the first gradient effect refers to the outer boundary outline of the target model gradually changing from a non-transparent state to a transparent state.

[0122] Step c: inverting the initial transparency parameter of the initial material ball to obtain an inverted material ball with inverted transparency parameter.

[0123] In this step, the initial transparency parameter carried by the initial material ball can be inverted; specifically, the difference between the initial transparency value at each pixel position and "1" is calculated to obtain an inverted material ball with inverted transparency parameters.

[0124] Step d: Using the second transparency difference between the second transparency parameter and the reverse transparency parameter at each pixel position, the second material ball and the reverse material ball are synthesized to obtain a fourth material ball with a fourth transparency parameter.

[0125] In this step, after obtaining the reverse material ball, the second transparency difference between the second transparency value of each pixel position in the second transparency parameter and the reverse transparency value of each pixel position in the reverse transparency parameter is calculated, and the second transparency difference of each pixel position is used to synthesize the second material ball and the reverse material ball to obtain a fourth material ball with a fourth transparency parameter; at this time, the target model is rendered using the fourth material ball to obtain a target model whose boundary has a second gradient effect and does not display the foreground pattern map.

[0126] Here, the second gradient effect refers to the outer boundary outline of the target model gradually changing from a transparent state to a non-transparent state.

[0127] Step e: Using the first maximum transparency value of each pixel position between the third transparency parameter and the fourth transparency parameter, the third material ball and the fourth material ball are synthesized to obtain a fifth material ball with a fifth transparency parameter.

[0128] In this step, the first transparency maximum value between the third transparency value of each pixel position in the third transparency parameter and the fourth transparency value of each pixel position in the fourth transparency parameter is calculated, and the third material ball and the fourth material ball are synthesized using the first transparency maximum value of each pixel position to obtain a fifth material ball with a fifth transparency parameter; at this time, the target model is rendered using the fifth material ball to obtain a target model whose outer circle boundary contour has a multi-layer gradient effect and does not display the foreground pattern map.

[0129] Step f: Using the second maximum transparency value of each pixel position between the second transparency parameter and the fifth transparency parameter, the second material ball and the fifth material ball are synthesized to obtain a first material ball with a first transparency parameter.

[0130] In this step, the second transparency maximum value between the second transparency value of each pixel position in the second transparency parameter and the fifth transparency value of each pixel position in the fifth transparency parameter is calculated, and the second material ball and the fifth material ball are synthesized using the second transparency maximum value of each pixel position to obtain a first material ball with a first transparency parameter; at this time, the target model is rendered using the first material ball to obtain a target model whose outer circle boundary contour has a multi-layer gradient effect and displays a foreground pattern map.

[0131] For the target model, the environment it belongs to will also have a certain degree of influence on its display effect, such as the lighting effects in the environment; in order to further increase the realism of the rendering effect, the rendered target object can be affected by false ambient light through the environment map, thereby creating a false lighting information for the rendered target model.

[0132] For some static texture maps, they may not have transparency parameters (for example, environment Matcap maps), that is, there are no parts with different transparency values ​​in such static texture maps (for example, environment Matcap maps), and each pixel position is completely opaque; at this time, it is impossible to adjust the transparency parameters in the material ball through the transparency parameters it carries. In this case, the transparency parameters in the material ball can be adjusted by using the grayscale pixel values ​​it carries or the pixel parameters of any color channel.

[0133] In another embodiment, the static texture map includes an environment map, and the first pixel parameters include grayscale pixel parameters and / or pixel parameters of any color channel; step S1021 includes: using the grayscale pixel parameters of the environment map or the pixel parameters of any color channel to adjust the initial transparency parameters of the initial material ball to obtain a first material ball with a first transparency parameter.

[0134] The environment map is used to render the environment pattern in the surface texture of the target model.

[0135] In this step, under the premise that the environment map does not have a transparency parameter, the grayscale pixel value of each pixel position in the environment map or the pixel parameter of any color channel is selected to adjust the initial transparency parameter of the initial material ball through corresponding calculations.

[0136] Here, if the grayscale pixel parameters of the environment map are used to adjust the initial transparency parameters, first, the obtained environment map is converted into a grayscale environment map to obtain the grayscale pixel value of each pixel position in the environment map, wherein the grayscale pixel value of each pixel position is a value in the range of 0 to 1; since the transparency parameter is actually also a value between 0 and 1, the grayscale pixel value of each pixel position in the grayscale environment map can be used to adjust the initial transparency parameter of the corresponding pixel position in the initial material ball through the corresponding calculation method to obtain a first material ball with a first transparency parameter.

[0137] In this way, the lighting information carried by the environment map can be passed to the material ball used to render the target object, so that the rendered target object can be affected by the fake ambient light, resulting in a more realistic target object.

[0138] It should be noted that the foreground pattern map and the environment map can be used to gradually adjust the initial transparency parameters of the initial material ball; that is, the foreground pattern map can be used to adjust the initial transparency parameters of the initial material ball first; then, the environment map can be used to perform a secondary transparency parameter adjustment based on the transparency parameters adjusted by the foreground pattern map to obtain a first material ball with a first transparency parameter; here, in fact, the adjustment order of the transparency parameters of the material ball by the foreground pattern map and the environment map is not restricted, that is, the transparency parameters of the material ball can be adjusted first by using the foreground pattern map, and then the transparency parameters after the initial adjustment can be adjusted for a secondary time by using the environment map; the transparency parameters of the material ball can also be adjusted first by using the environment map, and then the transparency parameters after the initial adjustment can be adjusted for a secondary time by using the foreground pattern map, which can be determined according to actual conditions and is not restricted here; wherein, the adjustment method for the transparency parameter is the same as the transparency adjustment method of the above embodiment, and will not be repeated here.

[0139] Step S1022: Using the second pixel parameter of the dynamic texture map that changes with time, adjust the first transparency parameter of the first material ball to obtain a target material ball whose transparency parameter changes with time.

[0140] In this step, the first transparency parameter carried by the first material ball is adjusted again based on the first transparency adjustment using the second pixel parameter of the dynamic texture map; similarly, the second pixel value at each pixel position in the dynamic texture map can be used to adjust the transparency value at the corresponding pixel position in the first material ball; here, since the second pixel parameter carried by the dynamic texture map changes with time, the transparency parameter of the target material ball obtained after adjustment using the second pixel parameter also changes with time.

[0141] Here, the second pixel parameters may include color parameters and transparency parameters (Alpha, A); the color parameters may include color parameters of three color channels of red (Red, R), green (Green, G), and blue (Blue, B) and grayscale pixel parameters, etc.

[0142] In one embodiment, the second pixel parameter includes a pixel parameter of any color channel; step S1022 includes: using the pixel parameter of any color channel of the dynamic texture map that changes with time, adjusting the first transparency parameter of the first material ball to obtain a target material ball whose transparency parameter changes with time.

[0143] In this step, for each pixel position in the dynamic texture map, the pixel value of any color channel at the pixel position is determined. For this pixel position, the pixel value of any color channel it has changes with time. On this basis, the pixel value at the pixel position that changes with time can be used to adjust the first transparency value at the corresponding pixel position in the first material ball, thereby obtaining a target material ball whose transparency parameter changes with time.

[0144] Here, the dynamic texture map may include a fog dynamic map and a light and shadow dynamic map; wherein the fog dynamic map is used to render fog effects on the surface texture of the target model; and the light and shadow dynamic map is used to render light and shadow effects on the surface texture of the target model.

[0145] It should be noted that the initial transparency parameter of the initial material ball can be gradually adjusted using static texture mapping and dynamic texture mapping; in the above embodiment, the initial transparency parameter of the initial material ball is first adjusted using static texture mapping; then, using dynamic texture mapping, a secondary transparency parameter adjustment is performed on the basis of the first transparency parameter obtained after the static texture mapping adjustment, to obtain a target material ball whose transparency parameter changes over time; here, in fact, the adjustment order of the transparency parameter of the material ball by the static texture mapping and the dynamic texture mapping is not restricted, that is, the transparency parameter of the material ball can be adjusted using the static texture mapping first, and then the transparency parameter after the initial adjustment can be adjusted for a secondary time using the dynamic texture mapping; the transparency parameter of the material ball can also be adjusted using the dynamic texture mapping first, and then the transparency parameter after the initial adjustment can be adjusted for a secondary time using the static texture mapping, which can be determined according to actual conditions and is not restricted here; wherein, the adjustment method for the transparency parameter is the same as the transparency adjustment method in the above embodiment, and will not be repeated here.

[0146] In one embodiment, see Figure 3 , Figure 3 This is a schematic diagram of the production process of a fog dynamic map provided in an embodiment of the present application. Figure 3 As shown, the fog dynamic map is obtained by the following steps:

[0147] Step S301: Obtain an original noise map according to the surface texture of the target model.

[0148] In this step, the original noise map used to render the fog effect on the surface of the target model can be obtained according to the display form of the surface texture of the target model in the game scene.

[0149] Step S302: Using a preset first offset parameter, perform offset processing on the first original coordinates of each pixel position in the original noise map to obtain a first offset coordinate of each pixel position.

[0150] In this step, the original noise map that was originally static can be made to "move" by means of UV flow; specifically, the first original coordinates of each pixel position in the original noise map can be offset using a preset first offset parameter. By changing the first original coordinates of each pixel position in the original noise map, the first original coordinates of the original noise map are changed over time, and the first offset coordinates of each pixel position are obtained; here, the first offset coordinates of each pixel position obtained move in a first specific direction over time; thereby, the original noise map that was originally static is offset in a first specific direction such as horizontally or vertically over time.

[0151] Here, the first specific direction may include horizontal, vertical, upper left, lower left, upper right, and lower right directions, and the offset angle of the first specific direction may also be specifically specified.

[0152] Step S303: Sampling the original noise map according to the first original coordinates of each pixel position and the first offset coordinates of each pixel position to obtain the fog dynamic map.

[0153] In this step, in order to make the original noise map have a "distorted" dynamic effect similar to floating smoke, the original noise map is sampled and processed through corresponding calculation processing according to the first original coordinate of each pixel position and the first offset coordinate of each pixel position, and then the fog dynamic map is obtained; for example, first, the first original coordinate of each pixel position is added to the first offset coordinate at the pixel position; then, the coordinate value of each pixel position obtained by the addition operation is input again to the corresponding pixel position in the original noise map, and the fog dynamic map can be obtained; at this time, the pixel parameters of any color channel of the fog dynamic map change over time.

[0154] Here, the corresponding operations may include addition, subtraction, OR, XOR, and negation operations, etc.

[0155] In another embodiment, see Figure 4 , Figure 4 This is a schematic diagram of the production process of a light and shadow dynamic map provided in an embodiment of the present application. Figure 4 As shown, the light and shadow dynamic map is obtained by the following steps:

[0156] S401: Obtain an original light and shadow map according to the surface texture of the target model.

[0157] In this step, the original light and shadow map used to render the light and shadow effects on the surface of the target model can be obtained according to the display form of the surface texture of the target model in the game scene.

[0158] S402: Using a preset second offset parameter, perform offset processing on the second original coordinates of each pixel position in the original light and shadow map to obtain a flowing light and shadow map.

[0159] In this step, the original light and shadow map that was originally static can also be made to "move" by flowing UV; specifically, the second original coordinates of each pixel position in the original light and shadow map can be offset using a preset second offset parameter. By changing the second original coordinates of each pixel position in the original light and shadow map, the second original coordinates of the original light and shadow map are changed over time, and the second offset coordinates of each pixel position are obtained, thereby obtaining a flowing light and shadow map; here, the second offset coordinates of each pixel position obtained move in a second specific direction over time; thereby, the original light and shadow map that was originally static is offset in a second specific direction such as the upper left or upper right over time.

[0160] Here, the second specific direction may include horizontal, vertical, upper left, lower left, upper right, and lower right directions, and the offset angle of the second specific direction may also be specifically specified.

[0161] S403. Perform an offset process on the second original coordinate of each pixel position in the original light and shadow map according to the flickering speed and flickering time of the light and shadow dynamic map on the texture surface of the target model to obtain a third offset coordinate of each pixel position.

[0162] In this step, for the target model, according to its own design, the light and shadow effects displayed on its surface can have a certain flickering speed and corresponding flickering time; therefore, in order to make the light and shadow dynamic map "flicker", according to the flickering speed and flickering time of the light and shadow dynamic map on the texture surface of the target model, the second original coordinates of each pixel position in the original light and shadow map are offset to obtain the third offset coordinates of each pixel position.

[0163] S404: Using the third offset coordinates of each pixel position, sample the original light and shadow map to obtain a scintillation light and shadow map.

[0164] In this step, in order to make the original light and shadow map have a "flickering" dynamic effect, the third offset coordinate of each pixel position is used to sample the original light and shadow map through corresponding calculation processing, and then a flickering light and shadow map is obtained; for example, first, the second original coordinate of each pixel position is added to the third offset coordinate at the pixel position; then, the coordinate value of each pixel position obtained by the addition operation is input again into the corresponding pixel position in the original light and shadow map to obtain a flickering light and shadow map.

[0165] S405 , synthesizing the flowing light and shadow map and the flickering light and shadow map according to the second offset coordinates of each pixel position and the third offset coordinates of each pixel position to obtain the light and shadow dynamic map.

[0166] In this step, in order to make the original light and shadow map have the dynamic effects of "flickering" and "flowing" at the same time, the second offset coordinate of each pixel position and the third offset coordinate of each pixel position are used to synthesize the flowing light and shadow map and the flickering light and shadow map through corresponding calculation processing, thereby obtaining a light and shadow dynamic map that is both "flickering" and "flowing"; for example, first, the second offset coordinate of each pixel position is multiplied by the third offset coordinate at the pixel position; then, the coordinate value of each pixel position obtained by the multiplication operation is limited to between 0 and 1, and the light and shadow dynamic map can be obtained.

[0167] In step S103, the target model is rendered using the obtained target material ball, so that a target model with a dynamic effect can be rendered according to parameter information such as transparency parameters carried in the target material ball.

[0168] In one embodiment, the texture map includes a foreground pattern map, an environment map, a fog dynamic map, and a light and shadow dynamic map; step S102 includes: gradually adjusting the initial transparency parameters of the initial material ball based on the pixel parameters of the foreground pattern map, the pixel parameters of the environment map, the pixel parameters of the fog dynamic map, and the pixel parameters of the light and shadow dynamic map, to obtain a gradually adjusted target material ball.

[0169] In this step, when the texture maps used to adjust the transparency parameters of the initial material ball include a foreground pattern map, an environment map, a fog dynamic map, and a light and shadow dynamic map, the initial transparency parameters of the initial material ball are gradually adjusted using the pixel parameters of the foreground pattern map, the pixel parameters of the environment map, the pixel parameters of the fog dynamic map, and the pixel parameters of the light and shadow dynamic map respectively;

[0170] Specifically, first, the initial transparency parameters of the initial material ball are adjusted using the pixel parameters of the foreground pattern map; secondly, the transparency parameters of the material ball after the foreground pattern map is adjusted using the pixel parameters of the environment map; then, the transparency parameters of the material ball after the environment map is adjusted using the pixel parameters of the fog dynamic map; finally, the transparency parameters of the material ball after the fog dynamic map is adjusted using the pixel parameters of the light and shadow dynamic map, to obtain a target material ball after gradual adjustment; wherein, the transparency parameters of the target material ball after gradual adjustment change over time.

[0171] It should be noted that, for the foreground pattern map, environment map, fog dynamic map and light and shadow dynamic map, there is no restriction on the order of adjusting the transparency parameters in the material ball. In other embodiments, the environment map can be used to first adjust the initial transparency parameters in the initial material ball; secondly, the foreground pattern map is used to adjust the transparency parameters of the material ball after the environment map is adjusted; then, the fog dynamic map is used to adjust the transparency parameters of the material ball after the foreground pattern map is adjusted; finally, the light and shadow dynamic map is used to adjust the transparency parameters of the material ball after the fog dynamic map is adjusted.

[0172] Step S103 includes: using the gradually adjusted target material ball to render the target model to obtain a target model with a dynamic effect; wherein the dynamic effect displays the foreground pattern map and the environment map, and has a fog effect and a light and shadow effect.

[0173] In this step, the target model is rendered using the target material ball that has been gradually adjusted through the foreground pattern map, environment map, fog dynamic map, and light and shadow dynamic map, so that a target model that displays the foreground pattern map, environment map, and has fog dynamic effects and light and shadow dynamic effects can be obtained.

[0174] The model rendering method for dynamic effects provided in an embodiment of the present application obtains the initial transparency parameter of an initial material ball based on the material information of the target model; adjusts the initial transparency parameter of the initial material ball based on the pixel parameters of the texture map to obtain a target material ball whose transparency parameter changes over time; and uses the target material ball to render the target model to obtain the dynamic effect of the target model. In this way, without the need to produce animation special effects, the target model with dynamic effects can be simulated by using the time-varying transparency parameter carried by the target material ball. In this way, by avoiding the use of animation special effects, the computational cost during the terminal device rendering process is reduced, and the difficulty of producing dynamic effects is reduced.
