[0027] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0028] With the rapid advancement of computer technology and game development technology, the game industry has entered an unprecedented stage of development. Game developers are no longer only concerned with the richness of game plots and gameplay, but are also paying more and more attention to the user's gaming experience. Special effects, as an important part of the gaming experience, can not only improve the beauty of the game screen, but also enhance the user's sense of immersion.

[0029] At present, many types of special effects have appeared in games and other application projects, such as explosion effects, lightning effects, particle effects, etc. The production methods of special effects are different, and the performance effects are also uneven. However, no wave effects with dynamic effects have been found so far. The wave effects shown in the game are mainly formed by rendering the pre-made wave model using wave maps, which lacks the dynamic sense of the waves. And when the wave effect in the game is not good, or other forms of wave effects need to be shown, it is often necessary to return to the model making software to recreate a new wave model, which undoubtedly increases the time cost of game development and reduces the efficiency of game development.

[0030] In view of this, the present application provides a method for generating an ocean wave animation. First, the method is based on an ocean wave animation production tool and preset parameter values ​​to adjust the shape of a plane model, thereby generating an ocean wave animation. Therefore, when the ocean wave effect in the game is not good, or when other forms of ocean wave effects need to be expressed, there is no need to rebuild the model. Ocean wave animations with different performance effects can be formed by simply modifying the parameter values, thereby reducing the time cost in the game development process and improving the game development efficiency. Second, the node parameters corresponding to each node in the ocean wave animation production tool include a group (a first number) of node sub-parameters, and these node sub-parameters correspond to each key frame of the ocean wave animation. Therefore, when the ocean wave animation production tool is called and the shape of the plane model is changed using the preset parameter values ​​for these node sub-parameters, at least the ocean wave model corresponding to each key frame can be formed, thereby generating an ocean wave animation including multiple frames, and realizing the dynamic expression of the ocean wave.

[0031] The following is a further detailed description of the method for generating an ocean wave animation, the method for rendering an ocean wave special effect, and the device, electronic device, and computer-readable storage medium described in the present application in conjunction with specific embodiments and drawings.

[0032] Figure 1 is an application system diagram of the method for generating ocean wave animation provided in the embodiment of the present application. Figure 1As shown, the system includes a first user terminal 101 and a first server terminal 102. The first user terminal 101 can be any device such as a smart phone, a tablet computer, a laptop computer, a desktop computer, a personal digital assistant (PDA), etc. The first server terminal 102 can be a processing module located inside the first user terminal 101, or a processing device electrically connected to the first user terminal 101, or a server connected to multiple first user terminals 101 in communication. The first server terminal 102 is deployed with a method for generating an ocean wave animation. In response to receiving multiple parameters sent by the first user terminal 101 (the multiple parameters are preset by the developer based on the first user terminal 101), the first server terminal 102 generates an ocean wave animation that meets the developer's expectations based on the method for generating an ocean wave animation.

[0033] Figure 2 1 is an application system diagram of the method for rendering the sea wave special effects provided in the embodiment of the present application. Figure 2 As shown, the system includes a second user terminal 201, a second server terminal 202, and a third server terminal 203. The second user terminal 201 can be any device such as a smart phone, a tablet computer, a laptop computer, a desktop computer, a personal digital assistant (PDA), etc. The second server terminal 202 can be a processing module located inside the second user terminal 201, or a processing device electrically connected to the second user terminal 201, or a server connected to multiple second user terminals 201 in communication. The second server terminal 202 is deployed with a game application for pre-rendered wave special effects and a rendering method for wave special effects. In response to receiving a wave special effect rendering instruction sent by the second user terminal 201, the second server terminal 202 uses the vertex animation texture corresponding to the wave animation imported from the third server terminal 203 (the third server terminal 203 is deployed with a method for generating wave animation) to render the corresponding wave special effects on the graphical user interface provided by the second user terminal 201.

[0034] The first embodiment of the present application provides a method for generating an ocean wave animation.

[0035] This method is deployed in Figure 1 The first server 102 is used to generate a wave animation that meets the developer's expectations. In an optional implementation, the wave animation generation method is executed by three-dimensional animation production software (such as Houdini).

[0036] Figure 3 Flowchart of the method for generating the ocean wave animation provided by this embodiment. Figure 3The method for generating the ocean wave animation provided by this embodiment is described in detail. The embodiments described below are used to explain the technical solution of this application and are not intended to be used as limitations for actual use.

[0037] like Figure 3 As shown, the method for generating the ocean wave animation provided in this embodiment includes the following steps S310 to S320:

[0038] Step S310, creating a plane model.

[0039] The plane model can be understood as a two-dimensional surface, without thickness, existing only on a plane. The plane model is usually composed of vertices, edges and faces. Optionally, the plane model is a quadrilateral patch, composed of four vertices and four edges, forming a plane area.

[0040] In this embodiment, the plane model is a basic model for making an ocean wave animation, and the plane model is changed into an ocean wave model with different ocean wave shapes by changing its shape.

[0041] Step S320, calling the wave animation production tool, adjusting the shape of the plane model based on multiple preset parameter values, and generating a wave animation; wherein the wave animation production tool includes multiple nodes connected in sequence, each node corresponds to at least one node parameter, the node is used to characterize the operation execution unit of the wave animation production tool, and is used to execute the corresponding preset operation, the node parameter includes a first number of node sub-parameters, the first number is the number of key frames preset for the wave animation, and each node sub-parameter corresponds to a key frame; the parameter value is preset for the node sub-parameter.

[0042] The wave animation production tool can be understood as a functional component preset by the developer, which is used to adjust the plane model into a wave model with a wave shape, thereby generating a wave animation composed of the wave model. The wave animation production tool is composed of a plurality of nodes connected in sequence, and the nodes can be understood as the basic units constituting the wave animation production tool, specifically, the operation execution units of the wave animation production tool, each node represents and executes a specific function or operation, and the nodes transmit data through the connection to form a complete processing flow.

[0043] A node can be considered as an independent functional unit, responsible for performing specific tasks, such as creating geometry, transforming objects, applying materials, simulating physics, etc. A node is preset with at least one node parameter, so that developers can assign different parameter values ​​to the node parameters to obtain different task results based on the node.

[0044] The node parameters can be understood as the configuration items included in each node. Developers can change the behavior or output of the node by adjusting the parameter values ​​configured by the configuration items. In this embodiment, the node parameters are composed of a set of node sub-parameters, which correspond to different stages of a configuration item. The stage can be represented by time, such as each node sub-parameter corresponds to a configuration item at a different time point, and can also be represented by a frame number, such as each node sub-parameter corresponds to a configuration item with a different frame number. In this embodiment, the frame number is used to distinguish the node sub-parameters included in the node parameters.

[0045] The wave animation production tool includes a plurality of nodes, each of which corresponds to at least one node parameter, each of which corresponds to a first number of node sub-parameters, and the first number corresponds to the number of key frames preset by the developer for the wave animation. Exemplarily, the key frames preset by the developer for the wave animation are 3 frames, including wave generation (first key frame), wave peak (second key frame), and wave hitting the shore (third key frame). Each node parameter will correspond to 3 node sub-parameters, and each node sub-parameter corresponds to one of the above key frames. When in the wave generation stage, the parameter value of the node sub-parameter corresponding to the first key frame will be used to adjust the shape of the plane model to form a wave model that simulates the wave generation shape.

[0046] In an optional implementation, the number of key frames is set by the developer based on the expectation of the wave special effect, and the wave special effect is often associated with the game events in the game, that is, when setting the number of key frames, the developer needs to consider the development rhythm of the game events that the wave special effect matches. Exemplarily, the developer pre-uses a 50-meter sea wave to match the wave skill. Since the development rhythm of the skill can include skill startup, skill assembly, and skill release, the wave special effect can be set to three stages to match the development rhythm of the wave skill. Since the wave special effect is preset to three stages, the developer will set the wave animation to include three key frames during the generation stage of the wave animation. For example, the first key frame corresponding to the wave generation stage is set to match the startup stage of the wave skill, the second key frame corresponding to the wave peak is set to match the assembly stage of the wave skill, and the third key frame corresponding to the wave hitting the shore is set to match the release stage of the wave skill. The number of key frames specifically set is associated with the game events that the wave special effect needs to match, and is not limited here.

[0047] In this step, the node parameters corresponding to each node in the wave animation production tool include a group (first number) of node sub-parameters, and these node sub-parameters correspond to a key frame of the wave animation, so when the three-dimensional animation production software calls the wave animation production tool and uses the parameter values ​​preset for these node sub-parameters to change the shape of the plane model, it can at least form a wave model corresponding to each key frame, thereby generating a wave animation including multiple frames, and realizing the dynamic expression of the waves. In addition, the node sub-parameters in the wave animation production tool are matched with the key frames preset for the wave animation, which reduces the number of node sub-parameters, which reduces the workload of developers in setting parameter values ​​on the one hand, and reduces the amount of data storage and memory usage during the animation production process on the other hand, thereby improving production efficiency.

[0048] In an optional implementation, calling an ocean wave animation production tool, adjusting the shape of the plane model based on a plurality of preset parameter values, and generating an ocean wave animation may specifically include the following steps S321 to S322:

[0049] Step S321, running multiple nodes, adjusting the shape of the plane model according to the parameter values ​​of multiple node sub-parameters corresponding to each key frame, to form a wave model corresponding to each key frame.

[0050] Step S322, generating an ocean wave animation according to the ocean wave model corresponding to each key frame.

[0051] Exemplarily, the developer presets three key frames for the wave animation, including wave generation (first key frame), wave peak (second key frame), and wave hitting the shore (third key frame). Each node parameter corresponds to three node sub-parameters, and each node sub-parameter corresponds to a key frame. For the first key frame, run multiple nodes, and adjust the plane model according to the parameter values ​​of the multiple node sub-parameters corresponding to the first key frame, and adjust the plane model from the original form to the first form that simulates the real wave generation form, and use the plane model of the first form as the wave model corresponding to the first key frame. For the second key frame, run multiple nodes, and adjust the plane model according to the parameter values ​​of the multiple node sub-parameters corresponding to the second key frame, and adjust the plane model from the original form to the second form that simulates the real wave peak form, and use the plane model of the second form as the wave model corresponding to the second key frame. For the third key frame, multiple nodes are run, and the plane model is adjusted in shape according to the parameter values ​​of multiple node sub-parameters corresponding to the third key frame, and the plane model is adjusted from the original shape to the third shape that simulates the shape of real waves hitting the shore, and the plane model in the third shape is used as the wave model corresponding to the third key frame. The wave animation is generated according to the wave model corresponding to the first key frame, the wave model corresponding to the second key frame, and the wave model corresponding to the third key frame.

[0052] In an optional implementation, generating an ocean wave animation according to an ocean wave model corresponding to each key frame may specifically include the following steps S322-1 to S322-2:

[0053] Step S322-1, based on the ocean wave models corresponding to the two adjacent key frames, an interpolation operation is performed to generate an ocean wave model corresponding to each frame between the two adjacent key frames.

[0054] Step S322-2, the wave models corresponding to the two adjacent key frames and the wave models corresponding to each frame between the two adjacent key frames form a wave animation.

[0055] The interpolation operation can be used to estimate or calculate the unknown value between two known data points. In this embodiment, the two known data points are the wave models corresponding to two adjacent key frames, and the unknown value is the wave model corresponding to each frame between the two adjacent key frames. Therefore, based on the interpolation operation, a smooth transition effect can be generated between two key frames, thereby forming a wave animation with a naturally changing wave shape.

[0056] Exemplarily, firstly, based on the difference operation, the wave model corresponding to the plurality of frames between the wave model corresponding to the first key frame and the wave model corresponding to the second key frame is generated. Secondly, based on the difference operation, the wave model corresponding to the plurality of frames between the wave model corresponding to the second key frame and the wave model corresponding to the third key frame is generated. The wave model corresponding to the first key frame, the wave model corresponding to the plurality of frames between the first key frame and the second key frame, the wave model corresponding to the second key frame, the wave model corresponding to the plurality of frames between the second key frame and the third key frame, and the wave model corresponding to the third key frame form a wave animation from wave generation to wave peak and then to wave hitting the shore.

[0057] The following is a detailed description of the wave animation tool:

[0058] In an optional implementation, the wave animation production tool includes at least a first node group, a second node group, a third node group, and a fourth node group. The first node group includes at least one node for adjusting the original form of the plane model to a first form with a bulge in the middle and the two ends maintaining the plane height, and the area occupied by the bulge in the middle in the plane model and the degree of bulge are determined by the parameter values ​​of the nodes included in the corresponding first node group. Based on different parameter values, different forms of the central raised area can be obtained, exemplarily, a central raised area with a small raised range and a small raised height, a central raised area with a small raised range but a large raised height, and a central raised area with a large raised range but a small raised height. The specific raised state is determined by the parameter values ​​set by the developer based on the expected wave model form; the second node group includes at least one node, which is used to compress the central raised area of ​​the first form along a first direction to form a second form including a central raised area and two side plane areas, the first direction is a direction perpendicular to the central raised area along the plane where the plane model is located, the two side plane areas are areas on both sides of the central raised area in the plane model except the central raised area, and the central raised area The degree of compression is determined by the parameter values ​​of the nodes included in the corresponding second node group; the third node group includes at least one node, which is used to change the position of the pivot point so that the central raised area of ​​the second form curls along the changed pivot point to form a third form including a central curling area and two side plane areas, and the pivot point position is determined by the parameter values ​​of the nodes included in the corresponding third node group; the fourth node group includes at least one node, which is used to attenuate the central curling area of ​​the third form on both sides along the second direction to form a fourth form including a central bulging area and two side plane areas, the second direction is a direction parallel to the central curling area, and the attenuation degree of the central curling area on both sides along the second direction is determined by the parameter values ​​of the nodes included in the corresponding fourth node group.

[0059] In a specific implementation, the first node group includes at least a fit node, an abs node, a complement node, a pow node, and a multiply node, wherein the fit node is used to adapt or scale a value to a specified range. For example, if there is a value between 0 and 100 and it needs to be converted to a value between 0 and 1, the fit node can be used to complete the conversion. The abs node represents the absolute value function, which is used to return the absolute value of the input value, such as inputting -5, the output will be 5. The complement node is a complement operation, which is used to perform a logical inverse operation on a value. For example, in binary operations, if a Boolean value or a binary number is input, the complement node will reverse its bit value (0 becomes 1, 1 becomes 0). The pow node represents a power operation, which is used to calculate another power of a number. For example, if two values ​​a and b are input, the pow node will calculate a to the power of b. The multuply node is a multiplication operation node, which is used to calculate the product of two or more values. For example, if two input values ​​a and b are input, the multiply node will calculate the result of a×b. Through the functions of the multiple nodes included in the first node group, the middle of the plane model can be raised while the two ends maintain the plane height, that is, the original form of the plane model is adjusted to the first form with the middle part raised and the two ends maintaining the plane height.

[0060] In a specific implementation, the second node group includes at least a fit node and a pow node. Through the functions of the multiple nodes included in the second node group, the range of the central raised area of ​​the first form can be limited, so that both sides of the central raised area form a smooth plane transition, the purpose is to leave room for the movement of the waves, and to facilitate the formation of an animation of the waves from generation to shore. Specifically, through the processing of the second node group, the central raised area of ​​the first form of the plane model can be compressed along the first direction (the direction perpendicular to the central raised area along the plane where the plane model is located), and the first form is adjusted to a second form including the central raised area and the plane areas on both sides.

[0061] In a specific implementation, the third node group includes at least a Transform Matrix node, which is used to operate a change matrix of a geometric body. The change matrix can be used to describe properties such as position, rotation, and scaling of a geometric body. Through the transformation matrix, precise transformation operations can be performed on the geometric body, such as translation, rotation, and scaling. In this embodiment, the Transform Matrix node is used to change the position of the pivot point so that the middle convex area of ​​the second form of the plane model curls along the changed pivot point to form a third form including a middle curled area and two side plane areas.

[0062] In a specific implementation, the fourth node group includes at least a vecto float node and a ramp node. The vecto float node is used to process vector data and can convert the XYZ coordinates of the space into three floating point values ​​corresponding to the X axis, the Y axis, and the Z axis respectively. The ramp node is used to create and edit color or value gradients and can create smooth color transitions or value changes. Through the functions of the multiple nodes included in the fourth node group, the middle curled area of ​​the third form of the plane model can be attenuated on both sides along the second direction (a direction parallel to the middle curled area, if the middle curled area is formed along the X axis, then the second direction is the direction of the X axis), forming a fourth form including a middle bulging area and two side plane areas.

[0063] Based on this, multiple nodes are run, and the plane model is morphologically adjusted according to the parameter values ​​of multiple node sub-parameters corresponding to each key frame to form a wave model corresponding to each key frame. Specifically, the following steps S11 to S16 may be included:

[0064] Step S11, obtaining parameter values ​​of multiple node sub-parameters corresponding to a first key frame, where the first key frame is any one of a first number of key frames.

[0065] Step S12, based on the first parameter value corresponding to the first key frame, run the first node group to adjust the original shape of the plane model to a first shape with a convex middle and plane height maintained at both ends, the first parameter value being the parameter value of the node included in the corresponding first node group among multiple parameter values.

[0066] Step S13, based on the second parameter value corresponding to the first key frame, run the second node group to adjust the first form of the plane model to a second form including a central raised area and two side plane areas, the second parameter value being the parameter value of the node included in the corresponding second node group among the multiple parameter values.

[0067] Step S14, based on the third parameter value corresponding to the first key frame, run the third node group to adjust the second form of the plane model to a third form including a central curled area and two side plane areas, the third parameter value being the parameter value of the node included in the corresponding third node group among the multiple parameter values.

[0080] Through the above node group, based on the preset parameter values, different forms of wave models corresponding to each key frame can be formed, thereby forming a wave animation.

[0081] The method provided in this embodiment adjusts the shape of the plane model through a variety of nodes, so that the formed wave model achieves a real wave effect.

[0090] In an optional implementation provided in this embodiment, the method provided in this embodiment may further include the following steps S331 to S332:

[0091] Step S331, encoding the vertex animation data of the wave model in the wave animation into a texture map to form a vertex animation texture map corresponding to the wave animation.

[0092] Step S332, exporting the vertex animation texture map to the game engine, so that the game engine renders the wave special effects corresponding to the wave animation based on the vertex animation texture map.

[0093] The Vertex Animation Texture (VAT) is an efficient animation storage technology that can reduce storage requirements and improve animation rendering efficiency.

[0094] Optionally, encoding the vertex animation data of the wave model in the wave animation into a texture map, and forming a vertex animation texture map corresponding to the wave animation can be achieved by the following operations: first, extracting the vertex position data of each frame from the wave animation, and the vertex position data is usually expressed in the form of vertex coordinates (X, Y, Z); second, using a script or tool to encode the vertex position data of each frame into a texture map, and a common encoding method is to store the position change of the vertex in the pixel color value of the texture map, and each pixel corresponds to a vertex. Exemplarily, the RGBA channel of the texture map is used to store the displacement of the vertex on the XYZ axis, and the color value of the pixel represents the position change of the vertex.

[0095] After the vertex animation texture map corresponding to the wave animation is formed, the vertex animation texture map can be imported into a game engine, such as a Messiah game engine, and the game engine can render the corresponding wave special effects in the game based on the vertex animation texture map.

[0096] Optionally, the game engine can render the wave effects based on the vertex animation texture map through the following operations: first, create a water material and assign the vertex animation texture map to the water material; second, create a shader, read the vertex position offset from the vertex animation texture map, and calculate the new position of each vertex according to the current time or frame number to render the wave effects.

[0097] In an optional implementation, the game engine renders the wave special effects corresponding to the wave animation based on the vertex animation texture map with a preset trigger condition. Specifically, in response to monitoring the game event, the shader is called, and the wave special effects are rendered in combination with the vertex animation texture map and the water material. Exemplarily, in response to monitoring the player triggering the wave skill during the game (such as the player using the wave props in the game backpack, the player clicking the wave skill control on the graphical user interface, etc.), the game engine calls the shader, combines the vertex animation texture map and the water material, and renders the wave special effects that match the wave skill.

[0098] The method provided in this embodiment generates wave animation based on the wave animation production tool. By changing the parameter values ​​of the node sub-parameters in the wave animation production tool, the expected wave shape can be obtained, which belongs to a bottom-level controllable programmatic control method. Encapsulating this method as a wave asset can facilitate the subsequent optimization of wave animation and secondary production of similar needs.

[0099] The first embodiment provides an optional method for producing wave animation. First, the method is based on the wave animation production tool and the preset parameter values ​​to adjust the shape of the plane model, thereby generating a wave animation. Therefore, when the wave effect in the game is not good or needs to show other forms of wave effects, it is not necessary to rebuild the model. Only by modifying the parameter value, a wave animation with different performance effects can be formed, which reduces the time cost in the game development process and improves the game development efficiency. Second, the node parameters corresponding to each node in the wave animation production tool include a group (first number) of node sub-parameters, and these node sub-parameters correspond to each key frame of the wave animation. Therefore, when the wave animation production tool is called and the parameter values ​​preset for these node sub-parameters are used to change the shape of the plane model, at least a wave model corresponding to each key frame can be formed, thereby generating a wave animation including multiple frames, and realizing the dynamic performance of the wave. Third, the wave animation production tool includes multiple node groups, each of which gradually changes the shape of the plane model from the details, so that the finally formed wave model has the shape of a real wave, which increases the realism of the wave animation and improves the user's immersion.

[0100] It should be noted that the examples in the first embodiment are only for explaining the method described in this application and are not intended to be limiting for actual use. The method for generating the wave animation provided in this application includes but is not limited to the method described in the first embodiment.

[0101] The second embodiment of the present application provides a method for rendering ocean wave special effects.

[0102] This method is deployed in Figure 2 The second server 202 is used to render the wave special effect during the game running process. In an optional implementation, the wave special effect rendering method is executed by a game engine (such as Messiah).

[0103] Figure 5 : is a flow chart of the method for rendering the sea wave special effects provided by this embodiment. Figure 5 The rendering method of the ocean wave special effect provided by this embodiment is described in detail. The embodiments described below are used to explain the technical solution of this application and are not intended to be used as limitations for actual use.

[0104] like Figure 5As shown, the rendering method of the ocean wave special effect provided in this embodiment includes the following steps S510 to S520:

[0105] Step S510, obtaining a vertex animation texture map, wherein the vertex animation texture map is formed by encoding vertex animation data of a wave model in an ocean wave animation into a texture map, and the ocean wave animation is generated based on a method for generating an ocean wave animation; wherein the method for generating an ocean wave animation comprises: creating a plane model; calling an ocean wave animation production tool, and adjusting the shape of the plane model based on a plurality of preset parameter values ​​to generate an ocean wave animation; wherein the ocean wave animation production tool comprises a plurality of nodes connected in sequence, wherein the nodes are used to characterize operation execution units of the ocean wave animation production tool, wherein each node corresponds to at least one node parameter, wherein the node parameter comprises a first number of node sub-parameters, wherein the first number is the number of key frames preset for the ocean wave animation, and each node sub-parameter corresponds to a key frame; and the parameter value is preset for the node sub-parameter.

[0106] Step S520, calling the shader, combining the vertex animation texture map and the water material, rendering the wave special effects corresponding to the wave animation.

[0107] The Vertex Animation Texture (VAT) is an efficient animation storage technology that can reduce storage requirements and improve animation rendering efficiency.

[0108] In this embodiment, the vertex animation texture map is formed by encoding the vertex animation data of the wave model in the wave animation into the texture map. Optionally, it is achieved by the following operations: first, extracting the vertex position data of each frame from the wave animation, and the vertex position data is usually expressed in the form of vertex coordinates (X, Y, Z); second, using a script or tool to encode the vertex position data of each frame into a texture map. The commonly used encoding method is to store the position change of the vertex in the pixel color value of the texture map, and each pixel corresponds to a vertex. Exemplarily, the RGBA channel of the texture map is used to store the displacement of the vertex on the XYZ axis, and the color value of the pixel represents the position change of the vertex.

[0109] After the wave animation is generated by the method described in the first embodiment of the present application, the vertex animation texture map corresponding to the wave animation can be formed based on the above method. After the game engine obtains the vertex animation texture map, it can render the wave animation based on the vertex animation texture map and the water material in the game engine to form a wave special effect. Optionally, the game engine can render the wave special effect based on the vertex animation texture map through the following operations: first, create a water material and assign the vertex animation texture map to the water material; second, create a shader, read the vertex position offset from the vertex animation texture map, and calculate the new position of each vertex according to the current time or frame number to render the wave special effect.

[0110] In an optional implementation, calling a shader, combining a vertex animation texture map and a water material, and rendering a wave special effect corresponding to the wave animation includes: in response to monitoring a game event, calling a shader, combining a vertex animation texture map and a water material, and rendering a wave special effect, that is, rendering the wave special effect is triggered based on a specific game event, and specifically, the game event can be a triggering event of a wave skill. Exemplarily, during the game, a player triggers a wave skill (such as using a wave prop in a game backpack, clicking a wave skill control on a graphical user interface, etc.), and the game engine calls a shader, combines a vertex animation texture map and a water material, and renders a wave special effect that matches the wave skill.

[0111] In a specific implementation, the rendered wave special effects will coordinate with the release rhythm of the wave skill. For example, when the ocean skill is in the startup stage, the first key frame of the wave animation is rendered, and the first key frame corresponds to the wave generation form. When the wave skill develops to the assembly stage, the second key frame of the wave animation is rendered, and the second key frame corresponds to the wave peak form. When the wave skill develops to the release stage, the third key frame of the wave animation is rendered, and the third key frame corresponds to the wave hitting the shore form, thereby forming a wave special effect that develops from wave generation to wave peak and then to wave hitting the shore.

[0112] Of course, the rendering of the wave special effects can also be triggered based on other game events, such as the emotional state of the controlled virtual character develops into mania, the weather in the virtual scene changes to a storm, etc. The specific details can be determined according to the game settings and are not limited here.
