This batch processing method requires the model to read the DA asset table every time an animation is played during the rendering phase, resulting in a more cumbersome rendering process and lower playback efficiency of the model animation.

Some of the block diagrams shown in the accompanying drawings may be functional entities and do not necessarily correspond to physically or logically independent entities.

In the description below, many specific details are provided to provide a full description of the embodiments of the present disclosure. However, those skilled in the art should appreciate that one or more specific details may be omitted when implementing the technical solution of the present disclosure, or one or more specific details may be replaced by other methods, components, devices, steps, etc.

[0020] In the related art, when batch processing is performed on the skeleton model, the skeleton animation data needs to be converted into a DA (DataAsset) asset table containing information such as the model and animation through a plug-in (for example, GPUSkin). This batch processing method requires the model to read the DA asset table every time an animation is played during the rendering phase, resulting in a more cumbersome rendering process and lower playback efficiency of the model animation.

[0021] In view of one or more of the above problems, exemplary embodiments of the present disclosure provide an animation data processing method, an animation data processing device, a computer program product, and an electronic device.

[0022] In an optional embodiment, reference Figure 1 As shown, a flowchart of an animation data processing method is provided, which specifically includes the following steps S110 to S120:

[0023] Step S110, acquiring multiple segments of skeletal animation data with the same model and the same material, and generating a map carrying multiple segments of animation according to the multiple segments of skeletal animation data with the same model and the same material;

[0024] Step S120, passing the map carrying multiple animations into the material to obtain the material with the map added, and in the material with the map added, dividing the multiple animations carried by the map to obtain multiple animation frame intervals; wherein the material with the map added is used to control the special effect particle emitter to emit special effect particles to generate a model animation that matches the multiple animation frame intervals.

[0025] Figure 1 In the method shown, by baking multiple segments of skeletal animation data into a map, passing the map containing multiple segments of animation into the corresponding material, and dividing the multiple segments of animation in the map in the material, the skeletal model can be batched and batched game assets can be directly produced; based on the material with the texture added, the special effect particle emitter is controlled to emit special effect particles to generate model animations that match multiple animation frame intervals, so that the GPU only needs to call the rendering function once to play multiple different animation frame intervals, which can improve the playback efficiency of the model animation.

[0026] Below Figure 1 Provide detailed instructions for each step.

[0027] In step S110, multiple segments of skeletal animation data with the same model and the same material are obtained, and a texture carrying multiple segments of animation is generated according to the multiple segments of skeletal animation data with the same model and the same material.

[0028] The model may be a dynamically changeable model object pre-made by an artist, such as a dynamically changeable model such as a character model or an animal model, and the present disclosure does not specifically limit this.

[0029] Among them, the skeletal animation data can be skeletal animation data pre-produced by artists for a specific model, and can include but is not limited to small-volume in-situ animation data. Exemplarily, after creating the model, the skeletal animation data corresponding to the model can be produced by an animation data production tool. It should be noted that the present disclosure does not specifically limit the generation method and source of the skeletal animation data corresponding to the model.

[0030] The model takes a horse as an example. Figure 2 As shown, a schematic diagram of a skeletal animation produced by an artist is provided. Skeletal animation data of multiple segments with the same model and material may include but is not limited to animation data of a horse in different states such as sleeping, running, and eating grass. The present disclosure does not make specific limitations on this.

[0031] Among them, the texture carrying multiple animations can record the animation through the offset information of the model vertices.

[0032] Exemplarily, multiple segments of skeletal animation data may be stored in a texture through the Vertex Animation Tools plug-in of UE (Unreal Engine) to obtain a texture carrying multiple segments of animation data.

[0033] In an optional embodiment, the above-mentioned generation of a texture carrying multiple animation segments based on multiple skeletal animation data with the same model and the same material can be achieved through the following steps: converting the animation data type of the multiple skeletal animation data with the same model and the same material to obtain vertex animation data with the same model and the same material; storing the vertex animation data with the same model and the same material into a texture to obtain a texture carrying multiple animation segments.

[0034] Optionally, the model can be driven to move according to the skeletal animation data, and the vertex information of each frame of the model can be recorded to obtain corresponding vertex animation data. Vertex animation data refers to key data used to describe or drive mesh vertex deformation during 3D graphics rendering.

[0035] Optionally, after obtaining vertex animation data with the same model and material for multiple segments, the vertex animation data with the same model and material for multiple segments can be merged to obtain merged vertex animation data, and the merged vertex animation data can be stored in a texture to obtain a texture carrying multiple segments of animation.

[0036] By converting skeletal animation data into vertex animation data, data support can be provided for the subsequent generation of textures carrying multiple segments of animation data, so that animation assets with the same model and material can be batched together, thereby improving model rendering efficiency.

[0037] In an optional embodiment, the above-mentioned storing vertex animation data of multiple segments of the same model and the same material into a map to obtain a map carrying multiple segments of animation can be achieved through the following steps: merging vertex animation data of multiple segments of the same model and the same material to obtain merged vertex animation data; generating a map carrying multiple segments of animation based on the merged vertex animation data.

[0038] For example, if the first segment of vertex animation data contains 10 animation frames, the second segment of vertex animation data contains 20 animation frames, and the third segment of vertex animation data contains 20 animation frames, these three segments of vertex animation data can be merged in sequence, that is, the second segment of vertex animation data is appended to the first segment of vertex animation data, and the third segment of vertex animation data is appended to the second segment of vertex animation data to obtain merged vertex animation data, and the merged vertex animation data contains a total of 50 animation frames of data.

[0039] For example, based on a preset merging rule, multiple segments of vertex animation data with the same model and the same material can be merged to obtain merged vertex animation data. The preset merging rule can be set by the developer, and the present disclosure does not specifically limit this.

[0040] By merging multiple segments of vertex animation data, it is possible to generate a map carrying multiple segments of animation, thereby achieving the purpose of batching.

[0041] In an optional embodiment, the above-mentioned skeleton animation data with multiple segments of the same model and the same material can generate a map carrying multiple segments of animation, which can also be achieved by the following steps: merging multiple segments of skeleton animation data with the same model and the same material to obtain merged skeleton animation data; and generating a map carrying multiple segments of animation based on the merged skeleton animation data.

[0042] For example, if the first segment of skeletal animation data contains 10 animation frames, the second segment of skeletal animation data contains 20 animation frames, and the third segment of skeletal animation data contains 20 animation frames, these three segments of skeletal animation data can be merged in sequence, that is, the second segment of skeletal animation data is appended to the first segment of skeletal animation data, and the third segment of skeletal animation data is appended to the second segment of skeletal animation data to obtain merged skeletal animation data, and the merged skeletal animation data contains a total of 50 animation frames of data.

[0043] For example, based on a preset merging rule, multiple pieces of skeletal animation data with the same model and material can be merged to obtain merged skeletal animation data. The preset merging rule can be set by the developer, and the present disclosure does not specifically limit this.

[0044] By merging multiple segments of skeletal animation data, it is possible to generate a texture that carries multiple segments of animation, thereby achieving the purpose of batching.

[0045] In step S120, a texture carrying multiple animation segments is passed into a material to obtain a material with the texture added thereto, and in the material with the texture added thereto, the multiple animation segments carried by the texture are divided to obtain multiple animation frame intervals; wherein the material with the texture added thereto is used to control a special effect particle emitter to emit special effect particles to generate a model animation that matches the multiple animation frame intervals.

[0046] Specifically, a texture carrying multiple animations can be passed into a target material to obtain a material with the texture added. The target material here can be the same material corresponding to multiple skeletal animation data.

[0047] For example, the animation frame interval can be represented by the frame interval formed by the start frame and the end frame of each animation segment in the merged whole animation, so as to distinguish the animations of different segments in the material. For example: the frame interval of the sleeping animation is 0-10 frames; the frame interval of the running animation is 11-15 frames; the frame interval of the grazing animation is 16-30 frames. Among them, the merged whole animation refers to a whole animation formed by merging multiple animation segments.

[0048] Optionally, the frame interval of the entire merged animation can be normalized so that the frame interval of each animation frame interval is mapped to the range of [0,1]. For example, the frame interval of the sleeping animation is mapped to 0-0.33; the frame interval of the running animation is mapped to 0.33-0.5; and the frame interval of the grazing animation is mapped to 0.5-1.

[0049] After obtaining the material with the texture added, the texture carrying multiple animation segments can be attached to the corresponding material to obtain the material with the texture added, and in the material with the texture added, the multiple animation segments carried by the texture can be cut apart to obtain multiple animation frame intervals, so as to distinguish different animation segments in the material.

[0050] In an optional embodiment, in the material to which the texture is added, the multiple animation segments carried by the texture are divided into multiple animation frame intervals, which can be achieved through the following steps: obtaining animation division parameters; according to the animation division parameters, in the material to which the texture is added, the multiple animation segments carried by the texture are divided into multiple animation frame intervals.

[0051] The animation division parameter refers to the parameter based on which the frame interval is divided, and the present disclosure does not make any specific limitation on this.

[0052] Optionally, by comparing the similarities of adjacent animation frames, division can be performed between two animation frames whose similarities are less than a preset threshold, so as to separate multiple animation segments carried by the texture and obtain multiple animation frame intervals.

[0053] Optionally, corresponding interval identifiers may be generated for different animation frame intervals so as to distinguish different animation frame intervals.

[0054] In an optional embodiment, the above-mentioned acquisition of animation division parameters can be achieved through the following steps: obtaining the number of animation frames and the animation merging order corresponding to the skeletal animation data of multiple segments of the same model and the same material; determining the animation division parameters according to the number of animation frames and the animation merging order corresponding to the skeletal animation data of multiple segments of the same model and the same material.

[0055] The animation merging order refers to the arrangement order of multiple skeletal animation data when baked into a texture. For example, according to the animation merging order of multiple skeletal animation data, the number of animation frames corresponding to the multiple skeletal animation data can be sorted in sequence to obtain a sorting result, and the multiple animation segments carried by the texture can be divided according to the sorting result to obtain multiple animation frame intervals.

[0056] Since the same materials and models can be batched, the present invention bakes multiple segments of animation data with the same models and materials into a map together, and separates them in the material, so that the materials and models corresponding to different animation frame intervals are the same, and batched game assets can be directly produced.

[0057] By splitting the multiple animation segments carried by the texture, multiple animation frame intervals are obtained, so that batched game assets can be directly produced, thereby realizing multi-animation switching and playback based on the GPU (graphics processing unit), thereby reducing performance consumption.

[0058] Materials with added maps can be used to control special effect particle emitters to emit special effect particles to generate model animations that match multiple animation frame intervals, which can realize GPU multi-animation playback and switching.

[0059] Optionally, a material with a map added is used to control a special effect particle emitter to emit special effect particles to generate a model animation that matches a target animation frame interval, where the target animation frame interval is an animation frame interval corresponding to a target interval identifier, and the target interval identifier is an interval identifier selected from interval identifiers of multiple animation frame intervals.

[0060] Specifically, the particle emitter can be controlled by adding a material with a texture to read the vertex animation data corresponding to the target animation frame interval in the texture to emit special effect particles, so as to render the model generated by the special effects and obtain the model animation that matches the target animation frame interval, thereby realizing the animation playback and switching of the special effect particles on the GPU.

[0061] For example, during the animation playback stage, an interval identifier can be randomly selected from the interval identifiers of multiple animation frame intervals as the target interval identifier; or an interval identifier can be selected from the interval identifiers of multiple animation frame intervals in a specific order as the target interval identifier, which is not specifically limited in the present disclosure. For example, taking a cow as an example, the model can be determined as the target interval identifier in the order of the interval identifier of the frame interval of the sleeping animation, the interval identifier of the frame interval of the grazing animation, and the interval identifier of the frame interval of the running animation.

[0062] By determining the target animation frame interval, that is, the animation frame interval to be played, the animation playback and switching of the batch model can be realized, which can be applied but not limited to the playback scenario of the standby animation.

[0063] Optionally, during the animation playback stage, the animation playback speed can be controlled by the playback time control parameters (such as frame interval time) configured in the special effects script. The shorter the frame interval time is set, the faster the playback speed; the longer the frame interval time is set, the slower the playback speed. The present disclosure does not make specific limitations on this.

[0064] Optionally, the special effect particle emitter emits special effect particles based on animation interpolation to generate animation frames matching the animation interpolation; the target animation frame interval is mapped to the [0, 1] interval; the animation interpolation is within the [0, 1] interval, and the animation interpolation increases a time increment for each animation frame generated.

[0065] Exemplarily, taking the target animation frame interval as the sleeping animation frame interval, the sleeping animation frame interval is 0-10 frames, and the frame interval can be remapped to the [0,1] interval to normalize the animation playback interval.

[0066] The animation interpolation can be regarded as a control parameter of the playback progress, which can be passed into the material to control the special effect particle emitter to emit special effect particles based on the animation interpolation through the material to generate animation frames matching the animation interpolation. The time increment can be the time increment added after each frame is played, such as 0.003, which is not specifically limited in the present disclosure.

[0067] For example, the current animation interpolation value is 0.1, and the sum of 0.1 and the time increment can be used as the next animation interpolation value. The progress increment is added to 0.1 each frame later, so that the value of 0.1 gradually increases, which is equivalent to the progress bar of the animation. The animation is played because of this value.

[0068] For example, when the frame interval of the target animation frame interval is mapped to the [0, 1] interval, Figure 3 The flowchart shown provides a method of controlling a special effect particle emitter to emit special effect particles to generate a model animation that matches a target animation frame interval, which may specifically include the following steps:

[0069] Step S301, determine the current animation interpolation, and the current animation interpolation starts from 0;

[0070] Step S302, based on the current animation interpolation, determining the animation frame in the target animation frame interval that matches the current animation interpolation;

[0071] Step S303, controlling the special effect particle emitter to emit special effect particles to render an animation frame that matches the current animation interpolation;

[0072] Step S304, increasing the current animation interpolation by a time increment, and determining whether the updated current animation interpolation exceeds 1; if not, jump to step S302; if so, execute step S305;

[0073] Step S305: the target animation frame interval is played.

[0074] Optionally, during the animation playback stage, after the target animation frame interval is played, an interval identifier can be randomly selected from the interval identifiers of multiple animation frame intervals as a new target interval identifier; based on the new target interval identifier, an animation frame interval that matches the new target interval identifier is determined from multiple animation frame intervals, and the special effect particle emitter is controlled to emit special effect particles to generate a model animation that matches the animation frame interval of the new target interval identifier, so as to realize GPU multi-animation switching, so that the GPU only needs to call the rendering function once to draw multiple identical objects, thereby reducing performance consumption and reducing the cost of animation rendering.

[0075] For example, Figure 4 As shown, a flowchart of batch processing of a skeleton model is provided, which may specifically include the following steps:

[0076] Step S401, obtaining multiple segments of skeletal animation data with the same model and the same material;

[0077] Step S402, converting the animation data type of multiple segments of skeletal animation data with the same model and the same material to obtain multiple segments of vertex animation data with the same model and the same material;

[0078] Step S403, storing the vertex animation data of multiple segments with the same model and the same material into a texture, and obtaining a texture carrying multiple segments of animation;

[0079] Step S404, passing the texture carrying multiple animations into the material to obtain the material with the texture added;

[0080] Step S405 , in the material to which the texture is added, multiple animation segments carried by the texture are cut into separate segments to obtain multiple animation frame intervals.
