[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The following explains the terms related to the present invention.

[0024] UV: In computer graphics and 3D modeling, UV mapping is a technology for applying a 2D texture image to the surface of a 3D model; UV coordinates are coordinates in a 2D space used to represent positions on the texture image; through UV mapping, the texture image can be accurately fitted to the surface of the 3D model, thereby adding color, details and material effects to the 3D model.

[0025] Currently, in order to produce an animation effect in which water contacts the surface of an object and wets the object, it is usually necessary to manually draw the wet area by staff according to the contact area between the water and the object. Different brushes and texture effects can be used to simulate the edges of water droplets and wet areas, so as to produce the wet effect generated by the collision between the water and the surface of the object. However, the above operations consume high time costs and labor costs.

[0026] In the related art, a three-dimensional drawing tool can be used to manually draw a wet area on a model. First, two texture maps need to be drawn. One is the state of the object when it first touches the water body, and the other is the state of the object when it is finally wet by the water body. Then, interpolation is performed between these two texture maps to obtain an animation effect of the object being gradually wet. However, this method requires staff to hand-draw texture maps, resulting in low animation production efficiency, low precision of the drawing effect, and great adjustment difficulty.

[0027] Based on this, an animation generation method, device, and electronic device provided by an embodiment of the present invention can be applied to a texture map sequence for making animation frames in three-dimensional software to achieve a dynamic dry-wet effect.

[0028] For ease of understanding of this embodiment, first, a detailed introduction to an animation generation method disclosed by an embodiment of the present invention is provided. This method can run on a local terminal device or a server and is applicable to various three-dimensional software, such as Maya software. As Figure 1 shown, this method includes the following steps:

[0029] Step S102, obtain animation information of the water body model; wherein, the animation information includes: the water body state in multiple consecutive animation frames;

[0030] In an animation containing a water body model, the water body states of different animation frames are usually different. This water body state can be the position, shape, etc. of the water body model in the animation frame. The water body model can be displayed as falling water droplets, a pool of water, or flowing water on the surface of an object in the animation frame.

[0031] Specifically, obtain the animation information of the water body model to obtain the water body state in multiple consecutive animation frames. For example, obtain the animation of the water body model flowing or the water body model colliding with an object from the system, and traverse each animation frame of this animation to obtain the position, shape, etc. of the water body model in each animation frame.

[0032] Step S104, based on the water body state in the animation frame, determine the contact position where the target model contacts the water body model;

[0033] The target model can be a ground model, a rock model, a tree model, etc., and a partial area of the water body model contacts the target model.

[0034] Specifically, first, the three-dimensional target model is converted into a two-dimensional UV coordinate system, and each coordinate point in the UV coordinate system corresponds to a model position of the target model; in the UV coordinate system, the position coordinates of the hair follicle points are evenly set at a preset interval. For example, if the preset interval is 2 unit lengths, then a position coordinate of a hair follicle point is set every 2 unit lengths, and a mapping relationship between the position coordinates of the hair follicle points and the model positions of the target model is established. Then, according to the mapping relationship between the position coordinates and the model positions, the hair follicle points are created on the surface of the target model. Here, if the preset interval is smaller, then the hair follicle points on the surface of the target model are denser, and the detection accuracy for the contact positions in the target model is higher.

[0035] It should be noted that the mapping relationship between the position coordinates of the hair follicle points and the model positions of the target model is usually a one-to-one correspondence to avoid one position coordinate mapping to multiple model positions, that is, one position coordinate corresponding to multiple hair follicle points, resulting in the situation of UV overlap.

[0036] Furthermore, according to the water body state in the animation frame, the distance between the hair follicle points and the water body model can be obtained. If the distance is less than the preset distance value, then the hair follicle points corresponding to the distance are determined as the target hair follicle points, and the model positions of the target hair follicle points on the target model are obtained as the contact positions on the surface of the target model when the target model contacts the water body model.

[0037] In the above method, determining the contact positions in the target model according to the water body state in the animation frame makes it simpler and more convenient to detect the area of the target model wetted by the water body.

[0038] Step S106: Generate a frame texture map corresponding to the animation frame based on the contact positions; wherein, the frame texture map includes: the model positions in the target model and the humidity information of the model positions.

[0039] This frame texture map contains the model positions in the target model. That is to say, after mapping the position coordinates of the hair follicle points to the pixel positions of the frame texture map, there is a mapping relationship between the pixel positions in the frame texture map and the model positions corresponding to the hair follicle points on the surface of the target model.

[0040] This humidity information can specifically include a completely wet state, a completely dry state, and an intermediate transition state. The intermediate transition state can be a relatively wet state such as a humidity percentage of 60, or a relatively dry state such as a humidity percentage of 40; the humidity information can usually be determined according to the pixel values in the frame texture map. If the pixel values of the pixel positions in the frame texture map are different, then the humidity information of the model positions in the target model is different.

[0041] Specifically, after the terminal determines the contact position of the contact water body model from the target model, according to the mapping relationship between the model position of the target model and the position coordinates of the hair follicle points, it extracts the position coordinates of the target hair follicle points from the UV coordinate system to obtain the target UV values; then, according to the target UV values and the mapping relationship between the position coordinates of the hair follicle points and the pixel positions of the frame texture map, in the target texture map, the area composed of the pixel positions corresponding to the position coordinates of the target hair follicle points is determined as the specified pixel area, and a graphic with a preset radius such as a circle is generated at the pixel positions corresponding to the position coordinates of the target hair follicle points. The pixels in the specified pixel area are set to the specified pixel value, and the specified pixel value indicates that the model position of the target model is in a completely wet state, that is, the humidity percentage at this model position is 100. The target texture map containing the specified pixel area can be determined as the texture map corresponding to the animation frame.

[0042] It can be understood that if the position coordinates of the target hair follicle points are denser, then the preset radius of the graphic generated at the pixel positions corresponding to the position coordinates of the target hair follicle points should be smaller, and the accuracy of the drawing effect for the wet area in the texture map is higher.

[0043] Here, the terminal determines the target texture map according to whether the animation frame is the first frame in a multi-frame continuous animation frame. When the animation frame is the first frame, the terminal obtains a preset texture map and uses the preset texture map as the target texture map of the animation frame. The pixels in the preset texture map are set with a preset pixel value, and the preset pixel value indicates that the model position of the target model is in a completely dry state, that is, the humidity percentage at this model position is 0; when the animation frame is not the first frame, the terminal determines the texture map corresponding to the previous animation frame of the animation frame as the target texture map. In a preferred manner, the preset pixel value is assigned 0, so that the pixel positions with a pixel value of 0 in the preset texture map indicate a completely dry state, and the color of the pixel positions is black; and, the specified pixel value is assigned 1, so that the pixel positions with a pixel value of 1 in the texture map indicate a completely wet state, and the color of the pixel positions is white.

[0044] This step of generating the texture map according to the contact position is beneficial to drawing the wet position in the target model and improving the accuracy of the drawing effect.

[0045] Step S108, obtain the texture map and map the texture map to the target model to render the animation of the target model.

[0046] Specifically, the terminal obtains multiple texture maps corresponding to multiple frame continuous animation frames, determines the specified pixel area for each texture map according to the mapping relationship between the pixel positions of each texture map and the position coordinates of the hair follicle points, and then maps the texture map corresponding to the animation frame to the target model according to the mapping relationship between the model position of the target model and the position coordinates of the hair follicle points.

[0047] Next, according to the pixel values in the frame texture map, obtain the humidity information of the model position indicated by the pixel values, and determine the rendering parameters of the model position based on the humidity information, and then render the target model. The rendering parameters can be parameters such as reflectivity, refractive index, transparency, and roughness. By adjusting the numerical values of the rendering parameters, the rendering effect obtained by rendering the target model can be controlled, so that the rendering effect of the model position matches the humidity information of the model position. For example, apply the frame texture map to the material of the target model. Here, assign the frame texture map to the corresponding attribute of the material, so as to adjust the numerical values of the rendering parameters and render the target model.

[0048] In the above method, by rendering the target model according to the humidity information of the model position included in the frame texture map to obtain the animation of the target model, the animation production efficiency can be improved.

[0049] In the above animation generation method, obtain the animation information of the water body model; wherein, the animation information includes: the water body state in multiple consecutive animation frames; based on the water body state in the animation frame, determine the contact position where the target model contacts the water body model from the target model; based on the contact position, generate a frame texture map corresponding to the animation frame; wherein, the frame texture map includes: the model position in the target model and the humidity information of the model position; obtain the frame texture map, map the frame texture map to the target model, and render to obtain the animation of the target model. In this method, there is no need for staff to hand-draw texture maps. The water body state in multiple consecutive animation frames can be directly obtained from the animation information of the water body model. According to the water body state, determine the contact position where the target model contacts the water body model from the target model, and then generate a frame texture map corresponding to each animation frame. This method determines the wetted area of the target model according to the water body contact situation, so that a sequence of frame texture maps of the animation can be automatically generated, improving the animation production efficiency and the accuracy of the texture map drawing effect.

[0050] The following embodiments provide a specific implementation manner for determining the contact position where the target model contacts the water body model from the target model.

[0051] Specifically, create follicle points on the surface of the target model; obtain the distance between the follicle points and the water body model, and determine the target follicle points with a distance less than a preset distance value; determine the model position of the target follicle points on the target model as the contact position where the target model contacts the water body model.

[0052] The above follicle points are usually evenly created on the surface of the target model. Optionally, generate follicles at the follicle points. The initial shape of the follicles is a sphere with a preset radius. When the distance between the follicle points and the water body model is less than the preset distance value, the follicles contact the water body model; according to the model position corresponding to the follicle points, determine the target shape of the follicles generated at the follicle points. For example, when the model position corresponding to the follicle points is located at the edge of the target model, the target shape of the follicles generated at the follicle points may be an ellipsoid. Mapping the follicles at the follicle points can display the graphics corresponding to the follicle shape.

[0053] In Figure 2 it, taking the target model as the ground model as an example, hair follicle points are created on the surface of the ground model, and then the distance between the hair follicle points and the water body model is obtained. If the distance is less than the preset distance value, then the hair follicle point is determined as the target hair follicle point, and further, the model position of the target hair follicle point on the target model is determined as the contact position; for example, the preset distance value is set to 0.01 cm. If the distance between the hair follicle point and the water body model is less than 0.01 cm, then the hair follicle point is confirmed as the target hair follicle point. For example, Figure 3 the two target hair follicle points within the square box in

[0054] In the above method, the hair follicle points with a distance less than the preset distance value from the water body model are determined as the target hair follicle points, and then the contact position on the surface of the target model is determined. The operation of determining the wetted position in the target model is simple and convenient.

[0055] Furthermore, obtain the UV coordinate system of the target model, set the position coordinates of the hair follicle points at preset intervals in the UV coordinate system, and establish the mapping relationship between the position coordinates and the model positions; at the model positions that have a mapping relationship with the position coordinates, create hair follicle points.

[0056] This UV coordinate system is usually used to represent the coordinate system after unfolding the three-dimensional target model into a two-dimensional plane image. The UV coordinates cannot overlap and the stretching of the UV coordinate system should be reduced during the unfolding process. That is to say, it is necessary to make the target model unfold reasonably, and each coordinate point of the UV coordinate system corresponds to a model position of the target model.

[0057] In the UV coordinate system, set the position coordinates of the hair follicle points at preset intervals. For example, if the preset interval is 2 unit lengths, then set the position coordinates of a hair follicle point every 2 unit lengths, and establish the mapping relationship between the position coordinates of the hair follicle points and the model positions of the target model. Then, according to the mapping relationship between the position coordinates and the model positions, create hair follicle points on the surface of the target model; at this time, the hair follicle points are relatively evenly attached to the surface of the target model. Assuming that the position coordinates of the hair follicle points are not mapped to the model positions, then such hair follicle points are usually generated at the origin position, and just delete such hair follicle points. Here, if the preset interval is smaller, then the hair follicle points on the surface of the target model are denser, and the detection accuracy for the contact position in the target model is higher.

[0058] It should be noted that there is a one-to-one mapping relationship between the position coordinates of the hair follicle points and the model positions of the target model to avoid a situation where one position coordinate maps to multiple model positions, that is, one position coordinate corresponds to multiple hair follicle points, resulting in the occurrence of UV overlap.

[0059] Taking the target model as the ground model as an example, as Figure 4 The ground model shown in (a) in Figure 4 is a three-dimensional model. After unfolding the ground model, the UV coordinate system shown in (b) in Figure 4 is obtained. In one example, if the UV coordinates of the target model are within the range of (0, 0) to (1, 1), and the preset interval is 2 unit lengths, then the position coordinates of the follicle points are set at the preset interval in the UV coordinate system, and the UV list [(0, 0), (0, 0.2),..., (1, 0), (1, 0.2),..., (1, 1)] can be obtained, where 1 unit length is 0.1. Traverse this list to obtain the UV values of each follicle point, and then set the parameter U and parameter V for each follicle point. For example, the cmds.setAttr() method provided by the API (Application Programming Interface) of Maya is used to set the parameter U and parameter V attributes of the follicle points.

[0060] In the above method, by setting the position coordinates of the follicle points at the preset interval, the density of the follicle points created at the model positions having a mapping relationship with the position coordinates can be controlled.

[0061] In one way, when the animation frame is the first frame in the animation information, a preset texture map is obtained and used as the target texture map for the animation frame; wherein, the pixels in the preset texture map are set with preset pixel values; the preset pixel values are used to indicate that the model position of the target model is in a completely dry state; when the animation frame is not the first frame in the animation information, the frame texture map corresponding to the previous animation frame of the animation frame is determined as the target texture map.

[0062] In one example, when the animation frame is the first frame in a multi-frame continuous animation frame, the terminal obtains a preset texture map and uses it as the target texture map for the animation frame. The resolution of the preset texture map can be user-defined. The pixels in the preset texture map are set with preset pixel values, and the preset pixel values indicate that the model position of the target model is in a completely dry state, that is, the humidity percentage of the model position is 0; in an alternative way, the preset pixel value is assigned 0, so that the color of the pixel position indicating the model position in a completely dry state in the preset texture map appears black; of course, the preset pixel value can also be assigned 1, so that the color of the pixel position appears white.

[0063] When the animation frame is not the first frame in the multi-frame continuous animation frame, the terminal determines the frame texture map corresponding to the previous animation frame of the animation frame as the target texture map.

[0064] The following embodiments provide specific implementation manners for generating the frame texture map corresponding to the animation frame.

[0065] Specifically, obtain the position coordinates of the target hair follicle points at the contact position; in the target texture map, generate a specified pixel area based on the position coordinates of the target hair follicle points; wherein, the pixels in the specified pixel area are set with a specified pixel value; the specified pixel value is used to indicate that the model position of the target model is in a completely wet state; determine the target texture map containing the specified pixel area as the frame texture map corresponding to the animation frame.

[0066] The terminal obtains the position coordinates of the target hair follicle points at the contact position of the target model, and can obtain the values of parameter U and parameter V, that is, the UV value; then determine the target texture map according to whether the animation frame is the first frame, and then generate a specified pixel area in the target texture map according to the position coordinates of the target hair follicle points. The specified pixel area indicates that the model position of the target model is in a completely wet state.

[0067] In an optional manner, the specified pixel value of the pixels in the specified pixel area is assigned a value of 1, so that the color of the pixel position indicating that the model position is in a completely wet state in the frame texture map appears white; of course, the specified pixel value can also be assigned a value of 0, so that the color of the pixel position appears black.

[0068] In an example, project the shape of the hair follicle generated at the target hair follicle point onto the target texture map. If the hair follicle generated at the target hair follicle point is a sphere, then a circle with a preset radius can be generated at the pixel position in the target texture map according to the graphic shape mapped by the sphere at the target hair follicle point and the pixel position corresponding to the position coordinates of the target hair follicle point; as Figure 5 In the example, when the water body model first contacts the target model, according to the pixel position mapped by the position coordinates of the target hair follicle point in the target texture map, multiple white circles with a preset radius are generated in the target texture map that appears black, and the multiple white circles with a preset radius are displayed as a superimposed effect. Optionally, according to the position coordinates of the target hair follicle point and the resolution of the target texture map, solve the pixel position where the graphic shape at the target hair follicle point is mapped in the target texture map.

[0069] It can be understood that if the position coordinates of the target hair follicle points are denser, then the preset radius of the graphic generated at the pixel position corresponding to the position coordinates of the target hair follicle points should be smaller, and the accuracy of the drawing effect for the wet area in the texture map is higher.

[0070] Here, the terminal obtains the target texture map containing the specified pixel area, and uses the target texture map containing the specified pixel area as the frame texture map corresponding to this animation frame.

[0071] Further, when the animation frame is not the first frame in the animation information, adjust the pixel values in the target texture map so that the adjusted pixel values are different from the specified pixel values; in the target texture map, generate a specified pixel area based on the position coordinates of the target hair follicle point; wherein, the pixel values in the target texture map are used to indicate the humidity information of the model position of the target model.

[0072] When the animation frame is not the first frame in a multi-frame continuous animation, the target texture map is usually the frame texture map corresponding to the previous animation frame of the animation frame; the terminal obtains the target texture map and adjusts the pixel values in the target texture map so that the pixel values in the adjusted target texture map are different from the specified pixel values.

[0073] Exemplarily, the target texture map contains preset pixel values indicating that the model position of the target model is in a completely dry state, first pixel values indicating that the model position of the target model is in a relatively dry state, second pixel values indicating that the model position of the target model is in a relatively humid state, and specified pixel values indicating that the model position of the target model is in a completely humid state. The terminal can reduce or increase the first pixel values, second pixel values, and specified pixel values by a specified pixel amplitude so that the adjusted pixel values are different from the specified pixel values, and set the preset pixel values as pixel thresholds.

[0074] Next, the terminal can determine the pixel position corresponding to the target hair follicle point in the target texture map according to the mapping relationship between the position coordinates of the hair follicle point and the pixel position, and then generate a specified pixel area. For example, Figure 6 in the shown example, the white area is the specified pixel area composed of the pixel positions corresponding to the target hair follicle points, that is, the model position corresponding to the white area is in a completely humid state; the black area is the area composed of the preset pixel values indicating that the model position is in a completely dry state; the gray area is the area composed of the pixel values indicating the intermediate transition state of the model position, that is, the humidity percentage of the model position corresponding to the white area is between 0 and 100, Figure 6 the darker the brightness of the gray area in [[ ]], the lower the humidity percentage of the model position of the target model.

[0075] Further, determine a target pixel area from the target texture map; wherein, the pixel values in the target pixel area are used to indicate that the model position of the target model is in a non-completely dry state; reduce the pixel values in the target pixel area by a specified pixel amplitude.

[0076] This specified pixel amplitude is usually used to control the amplitude of the decrease in the humidity percentage of the model position of the target model, that is, to control the speed at which the model position changes from a non-completely dry state to a completely dry state. The specified pixel amplitude can be adjusted by the user according to needs; the non-completely dry state can specifically include a completely humid state, or a completely humid state and an intermediate transition state.

[0077] Exemplarily, in the frame texture map corresponding to the previous frame of the animation frame, the area composed of the pixel positions indicating that the model position of the target model is in a non-fully dry state is determined as the target pixel area; assuming that the specified pixel amplitude is set to 0.1, then the pixel values in the target pixel area of the target texture map are reduced at the specified pixel amplitude of 0.1 per frame. For example, in the frame texture map corresponding to the previous frame of the animation frame, there is a specified pixel area with a pixel value of 1 (showing white). Taking this specified pixel area as the target pixel area and reducing the pixel values in the target pixel area of the target texture map at the specified pixel amplitude of 0.1, then after 10 animation frames in which the specified pixel amplitude decreases for each frame of the animation frame, the target pixel area in the target texture map shows black.

[0078] In the above method, by adjusting the pixel values in the target pixel area with the specified pixel amplitude, the process of the wet area in the target model changing from wet to dry can be simulated.

[0079] Specifically, the color level break in the frame texture map is smoothed to obtain a frame texture map with a smooth transition effect.

[0080] This smoothing process can be the fusion transition of black, white, and gray, or the edge transition of non-black pixels, and can be specifically implemented through PIL (Python Imaging Library, a Python image processing library).

[0081] According to the foregoing embodiments, the pixel values in the target texture map are adjusted with the specified pixel amplitude, and then a specified pixel area is generated in the target texture map. Therefore, the frame texture map contains different pixel values indicating different humidity information of the model position, and different pixel values are displayed as different colors in the frame texture map, which will cause a color level break in the frame texture map, such as Figure 6 the dividing line shown in. Here, the color level break in the frame texture map can be smoothed through the fusion transition of black, white, and gray, making the transition at the edge of the color level break more natural and smooth.

[0082] The following embodiments provide a specific implementation method for rendering the animation of the target model.

[0083] Specifically, multiple frame texture maps corresponding to multiple consecutive animation frames are obtained, and a specified pixel area is determined from the multiple frame texture maps; based on the specified pixel area, the frame texture map corresponding to the animation frame is mapped to the target model; based on the humidity information of the model position, the rendering parameters of the model position are determined, and the model position is rendered through the rendering parameters; among them, in the rendered target model, the humidity effect of the model position matches the humidity information of the model position indicated by the frame texture map.

[0084] The rendering parameters can be parameters such as reflectivity, roughness, transparency, refractive index, etc., and the humidity effect of the model position of the target model is controlled through the rendering parameters.

[0085] Exemplarily, the terminal obtains multiple frame textures corresponding to multiple consecutive animation frames from the system, determines a specified pixel region for each frame texture, and then maps the frame texture corresponding to the animation frame to the target model according to the mapping relationship between the pixel positions of the frame texture and the position coordinates of the hair follicle points, as well as the specified pixel region determined in the frame texture. Then, according to the mapping relationship between the model position of the target model and the position coordinates of the hair follicle points, when mapping the frame texture to the target model, it can be understood that the UV values of the model position included in the frame texture are mapped within the range of (0, 0) to (1, 1) in the two-dimensional UV coordinate system, regardless of the resolution of this frame texture.

[0086] Next, according to the pixel values in the frame texture, obtain the humidity information of the model position indicated by the pixel values, and determine the rendering parameters of the model position according to the humidity information, and then render the target model. The rendering parameters can be parameters such as reflectivity, refractive index, transparency, and roughness; by adjusting the values of the rendering parameters, the rendering effect obtained by rendering the humidity effect of the model position of the target model can be controlled, so that the rendering effect of the model position matches the humidity information of the model position. As Figure 7 shown in (a) below, apply the frame texture to the material of the target model. The rendered target model is as Figure 7 shown in (b) below. Here, assign the frame texture to the property corresponding to the material, control the values of the rendering parameters of the target model according to the humidity information of the model position indicated by different pixel values in the frame texture, and then render the target model through the rendering parameters.

[0087] Here, different frame textures correspond to different animation frames. In different frame textures, the pixel values at different pixel positions usually change. Therefore, multiple frame textures need to be set in the form of a frame texture sequence; in the rendered target model, the humidity effect of the model position matches the humidity information of the model position indicated by the pixel values in the frame texture.

[0088] In the above method, the rendering parameters of the target model are determined based on the humidity information of the model position indicated by the pixel values in the frame texture, and then the target model is rendered. By controlling the rendering parameters, the humidity effect of the model position is controlled, and the rendering of the target model has convenience and controllability.

[0089] Furthermore, when the animation frame is the last frame in the animation information, based on the humidity information of the model position, determine the target pixel region from the frame texture, and gradually adjust the pixel values in the target pixel region to the preset pixel values.

[0090] In an alternative approach, when the animation frame is the last frame among a sequence of multiple consecutive animation frames, after completing the rendering process for the last animation frame in the texture map sequence, the pixel values in the target pixel area can be continuously decreased until the pixel values in the frame texture map corresponding to the last frame in the animation frame are all 0. At this time, the surface of the target model resumes the effect of being completely dry; during the process of gradually adjusting the frame texture map corresponding to the last frame in the animation frame to a preset pixel value, based on the humidity information of the model position indicated by the pixel values in the frame texture map, the rendering parameters of the model position are determined, and then the rendering effect obtained by rendering the target model is controlled.

[0091] In one approach, the rendering parameters of the target model can be determined in the following manner.

[0092] Specifically, based on the humidity information of the model position, the parameters in the reflectivity map and / or roughness map of the target model are adjusted.

[0093] Exemplarily, obtain the frame texture map corresponding to an animation frame. Based on the humidity information of the model position indicated by different pixel values in the frame texture map, generate the reflectivity map of the target model, or the reflectivity map, or the reflectivity map and roughness map; then, for the frame texture maps corresponding to different animation frames, adjust the parameters in the reflectivity map or roughness map to obtain the adjusted reflectivity map or roughness map. The terminal renders the target model according to the reflectivity map corresponding to the animation frame to obtain a reflection effect that matches the humidity information of the model position; renders the target model according to the roughness map corresponding to the animation frame to obtain a rough effect that matches the humidity information of the model position.

[0094] The above embodiments of the present application can generate a high-precision frame texture map sequence through an automated method based on object contact detection, and use the PIL library of Python to generate and update the frame texture map sequence to achieve a dynamic wet and dry effect; quickly and flexibly implement animation production and wet and dry transition effects, provide rich adjustable parameters for users, and provide a fast and controllable method for producing the wetting effect when a conventional object contacts with water.
