[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] First, some nouns or terms that appear in the description of the embodiments of the present application are subject to the following explanations:

[0035] 3D animation software (Houdini): is a computer graphics and special effects software that can be widely used in the film, television and game industries to create complex special effects, simulations and animations. Houdini has a powerful node-based workflow and programmable functions, enabling users to create highly customizable effects, and can also be used to simulate fluids, cloth and other physical phenomena.

[0036] Unreal Engine (UE): is a game engine used to create various types of video games, virtual reality and augmented reality applications. The engine provides powerful tools and features that can be applied to the development of simulation games, horror games, role-playing games and many other different types of games.

[0037] Vertex Animation Texture (VAT) technology: It bakes vertex animation information into texture maps for use in vertex shaders. VAT records the displacement data of each vertex in a texture, and then inputs the texture into the world position parameter of the vertex shader, so that the GPU can restore each frame of animation. The data format of the VAT texture is very simple and intuitive. The horizontal axis is that each point corresponds to a vertex on the aggregate; the vertical axis is the time axis. Each point on the plane corresponds to the coordinate displacement of a vertex at a certain moment.

[0038] The VAT technology in the related art provides the basis for cloth simulation, and can provide cloth effects in real-time rendering engines that are similar to offline solution simulation. However, in real-time rendering engines, what is needed is not only a single cloth simulation animation, but more importantly, a cloth simulation animation that can change at any time to adapt to different states. There are some defects in the current VAT technology, including: the size of the generated texture is affected by the number of vertices and the length of the animation. When the number of vertices is too large or the animation is too long, the generated texture will be very large, resulting in an increase in the amount of video memory occupied; it does not support mixed transitions and physical collisions between animations; it is impossible to use the animation state machine to control actions; the accuracy of the action information is affected by the storage format, which may cause the read animation to be inaccurate; it is impossible to implement functions such as Inverse Kinematics (IK) in skeletal animation.

[0039] Therefore, the current VAT technology cannot meet the requirements of real-time rendering engines for flexibility and variability, and consumes a lot of resource performance during real-time rendering, further affecting the cloth simulation effect.

[0040] The above method embodiments involved in this application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, the mobile terminal can be a smart phone, a tablet computer, a PDA, a mobile Internet device, a PAD, a game console and other terminal devices. Figure 1 1 is a hardware structure block diagram of a mobile terminal of an information processing method according to an embodiment of the present application. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP) chip, a microprocessor (MCU), a field-programmable logic device (FPGA), a neural network processor (NPU), a tensor processing unit (TPU), an artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data. In one embodiment of the present application, it may also include: an input and output device 108 and a display device 110.

[0041] In some optional embodiments mainly based on game scenarios, the above-mentioned device can also provide a human-computer interaction interface with a touch-sensitive surface, which can sense finger contact and / or gestures to perform human-computer interaction with a graphical user interface (GUI). The human-computer interaction function may include the following interactions: creating web pages, drawing, word processing, making electronic documents, games, video conferencing, instant messaging, sending and receiving emails, call interface, playing digital videos, playing digital music and / or web browsing, etc. The executable instructions for executing the above-mentioned human-computer interaction functions are configured / stored in a computer program product or readable storage medium executable by one or more processors.

[0042] Those skilled in the art will understand that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0043] According to one embodiment of the present application, an embodiment of an information processing method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0044] Figure 2 is a flow chart of an information processing method according to one embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0045] Step S21, obtaining animation texture information and vertex offset information of a virtual model to be used in a game scene, wherein at least part of the virtual model uses a preset material cloth, the animation texture information is used to record vertex animation data obtained by pre-offline solution, and the vertex offset information is used to record vertex offset data of the preset material cloth between a plurality of different cloth display states and an initial state;

[0046] Step S22, mixing the animation map information and the vertex offset information to determine the target cloth display form of the virtual model;

[0047] Step S23, rendering in the game scene according to the target cloth display form to obtain a virtual model.

[0048] At least some of the above virtual models use preset material fabrics to better simulate the material properties in the real world. The virtual model can be a flag model, a clothing model, etc. The preset material fabrics can include various textures, colors, and glossiness, which help the model to more realistically show the appearance and texture of different materials, and can also improve the visual quality of the virtual model, making the virtual model more attractive and realistic. It should be noted that the flag model is used as an example in the embodiments of the present application, but it does not constitute a specific limitation on the virtual model.

[0049] The above-mentioned animation map information is used to record the vertex animation data obtained by offline solution in advance, and usually contains information such as vertex position, normal, texture coordinates, etc. of each frame. The animation map information can be used to quickly update the vertex data of the virtual model at runtime to achieve smooth animation effects. Animation maps can reduce the computing burden of the CPU and improve rendering efficiency, so that they can be effectively applied to resource-limited platforms such as mobile devices.

[0050] The above vertex offset information is used to record the vertex offset data of the preset material cloth between multiple different cloth display states and the initial state, and is used to dynamically adjust the vertex position at runtime to display different cloth states. The vertex offset information can reflect the changes of cloth stretching, contraction, distortion, etc., so as to achieve more realistic cloth effects in games or animations. Taking the flag model as an example, the multiple different cloth display states include but are not limited to the static state, the moving state, and the state of being inserted into the ground by the virtual character.

[0051] Figure 3 is a schematic diagram of a cloth display state according to one embodiment of the present application, such as Figure 3 As shown, in a static state, the flag presents a vertical shape, the fabric hangs naturally vertically, and the whole presents a calm state. The shape of the flag will vary depending on the material and design of the fabric, and can be a flat plane shape or a shape with folds and ripples. Figure 4 is a schematic diagram of another cloth display state according to one embodiment of the present application, such as Figure 4 As shown, in the moving state, the flag can flutter in the wind and change its shape. The fabric will be blown by the wind, producing a wavy shape, and the whole thing presents a dynamic state. Figure 5 is a schematic diagram of another cloth display state according to one embodiment of the present application, such as Figure 5 As shown in the figure, when the flag is inserted into the ground by the virtual character, the shape of the flag will change. The fabric will be pulled or affected by external forces and become twisted and deformed, and the overall appearance will be messy and no longer maintain its original neat state.

[0052] Furthermore, the animation map information and the vertex offset information are mixed to determine the target fabric display form of the virtual model, and the virtual model is rendered in the game scene according to the target fabric display form. This allows the virtual model to display various fabric forms in the game scene, making the game scene more vivid and realistic.

[0053] Based on the above steps S21 to S23, by obtaining the animation map information and vertex offset information of the virtual model to be used in the game scene, and then mixing the animation map information and the vertex offset information, the target fabric display form of the virtual model is determined, and finally the virtual model is rendered in the game scene according to the target fabric display form, so that the virtual model with a real fabric effect can be displayed in the game scene. By mixing the animation map information and the vertex offset information, the dynamic effect of the virtual model in different fabric display states can be achieved, making the virtual model look more vivid and realistic, further improving the visual effect in the game scene, enhancing the user's immersion and experience, and improving the fun and attractiveness of the game, thereby solving the technical problems of poor rendering flexibility and high resource consumption when implementing fabric simulation in a real-time rendering engine in the related technology.

[0054] The information processing method in the embodiment of the present application is further introduced below.

[0055] Optionally, the initial state is a flat state of a cloth of a preset material.

[0056] Specifically, the initial state is a flat state of a cloth of a preset material. Figure 6 is a schematic diagram of an initial state according to one embodiment of the present application, such as Figure 6 As shown, in the flat state, the preset material cloth has no wrinkles. The initial state can also be, but is not limited to, a taut state, a straightened state, or a smooth state of the preset material cloth, in which the preset material cloth may have a few wrinkles.

[0057] In order to realize the free transition of the virtual model between various cloth display states, it is necessary to set the default initial state of the virtual model. When the flat state of the preset material cloth is determined as the initial state, the average adaptation effect for subsequent conversion to any state is better. If the initial state of the virtual model is a state with too many wrinkles on the surface, the normal information in this state will affect the average adaptation effect when converting to other states.

[0058] Optionally, in step S21, obtaining animation texture information of a virtual model to be used in a game scene includes:

[0059] Step S211, performing offline solving on the cloth animation of the preset material cloth to obtain a solving result, wherein the solving result is used to record the animation data of each vertex of the virtual model in the cloth animation;

[0060] Step S212, using vertex animation texture method to bake the solution result, to obtain animation texture information of the virtual model to be used in the game scene.

[0061] Specifically, in the offline solving process of the cloth animation of the preset material cloth, in the cloth animation of the preset material cloth, each vertex is animated by a computer program to obtain the position, rotation, scaling and other data of each vertex during the animation process, which usually requires a lot of computing resources and time. The physical properties of the cloth, such as gravity, friction, elasticity, etc., need to be considered during the solving process to ensure that the animation effect conforms to the movement law of the real cloth. The solving results can be saved as vertex animation data for use by the rendering engine to achieve the playback and rendering of the cloth animation.

[0062] The animation data of each vertex of the virtual model in the cloth animation includes information such as the position, rotation, scale, normal direction, etc. of each vertex in the cloth animation. Each vertex animation data can be used to achieve realistic cloth effects in real-time rendering, allowing the virtual model to show vivid cloth movement and deformation effects in the animation.

[0063] Furthermore, the VAT technology can be used to bake the animation data of each vertex in each frame of the offline simulated cloth animation into a texture, thereby obtaining the animation texture information of the virtual model to be used in the game scene. By combining the frame number information stored in the UV channel of the virtual model, the offline solution result can be restored to the vertex animation of the virtual model.

[0064] Continuing with the flag model as an example, three sets of vertex animation maps were solved offline in advance in Houdini and baked. Figure 7 is a vertex animation map according to one embodiment of the present application, and the vertex animation map corresponding to the flag model in a static state is as follows Figure 7 shown. Figure 8 is another vertex animation map according to one embodiment of the present application, such as Figure 8 As shown, the vertex animation map corresponding to the flag model in the moving state is as follows Figure 8 shown. Fig. 9 is another vertex animation map according to one embodiment of the present application, such as Fig. 9 As shown in the figure, the corresponding vertex animation map of the flag model when the virtual character is inserted into the ground is as follows Fig. 9 shown.

[0065] Based on the above optional embodiment, the cloth animation of the preset material cloth is solved offline to obtain the solution result, and then the solution result is baked using the vertex animation texture method to obtain the animation map information of the virtual model to be used in the game scene, so that the animation map information of the virtual model can be used in the game scene, so that the virtual model has a more realistic cloth animation effect in the game, further enhancing the realism and interactivity of the game scene, improving the game experience, and making the player more immersed in the game environment. At the same time, through the offline solution and map baking method, the burden of the game engine can be effectively reduced, and the running efficiency and performance of the game can be improved.

[0066] Optionally, in step S21, obtaining vertex offset information of a virtual model to be used in the game scene includes:

[0067] Step S213, calculating vertex position offsets of the virtual model between a plurality of different cloth display states and an initial state, wherein the vertex position offsets are used to record the position difference between the vertex position of the virtual model in the current cloth display state and the vertex position of the virtual model in the initial state, and the current cloth display state is any one of the plurality of different cloth display states;

[0068] Step S214, obtaining vertex offset information of the virtual model to be used in the game scene based on the vertex position offset.

[0069] Specifically, the vertex position offset is also called the offset variable. In the process of calculating the offset variable, the vertex position of the virtual model in the initial state is first obtained, which can be obtained through the initial state information recorded when the model is loaded. According to the current cloth display state, the virtual model is cloth displayed and the corresponding vertex position information is obtained. Then the vertex position in the current cloth display state is compared with the vertex position in the initial state, and the position difference between the vertex positions in different states is calculated. By repeating the above steps, the vertex position offset of the virtual model in a variety of different cloth display states is calculated, so as to compare and analyze the display effects of the virtual model in different states. After obtaining the vertex position offset, the vertex offset information of the virtual model to be used in the game scene is obtained based on the vertex position offset.

[0070] Based on the above optional embodiments, by calculating the vertex position offsets of the virtual model between a plurality of different cloth display states and the initial state, and then obtaining the vertex offset information of the virtual model to be used in the game scene based on the vertex position offsets, the dynamic change of the virtual model in different cloth display states is realized, and the accurate vertex offset information of the model can be obtained according to the vertex position offsets, which can make the virtual model in the game scene more realistic and vivid, and enhance the user's immersion and experience. At the same time, by calculating and processing the vertex position offsets, a more accurate cloth simulation effect can also be achieved, which improves the realism and quality of the game screen.

[0071] Optionally, the information processing method in the embodiment of the present application also includes: using a color map to store vertex offset information, wherein multiple vertex color channels of the color map are respectively used to store vertex coordinate offset data of the virtual model in any one of a plurality of different fabric display states.

[0072] Optionally, the color values ​​respectively stored in the plurality of vertex color channels are obtained by normalizing the vertex coordinate offset data.

[0073] Specifically, after obtaining the vertex offset information of the virtual model to be used in the game scene based on the vertex position offset, the vertex offset information can be stored in the virtual model UV, or stored in the model binding as a blendshape. Using a color map to store vertex offset information is no longer limited by the limitations of the virtual model itself, and an unlimited number of states can be baked. By adjusting the compression algorithm, the problem of insufficient precision of the color map can be avoided.

[0074] After obtaining the offset variable, store the offset variable in each vertex color (RGB) channel. Taking the offset variable as (x, y, z) as an example, the offset variable is stored in the corresponding vertex color channel through the following calculation process:

[0075] r=x×0.05+0.2

[0076] g=z×0.05+0.2

[0077] b=y×0.05+0.2

[0078] In the above calculation process, since the vertex offset information needs to be imported into the UE engine for use later, and the coordinate systems of Houdini and UE engines are different, y and z need to be swapped. Through the above calculation process, the offset variable can be compressed between 0 and 1, thereby realizing the normalization of the vertex coordinate offset data, thereby avoiding the loss of information caused by the range exceeding the threshold being clipped when switching engines.

[0079] Based on the above optional embodiment, by storing vertex offset information in multiple vertex color channels of a color map, more efficient model rendering and storage can be achieved while reducing the demand for additional storage space.

[0080] Optionally, the information processing method in the embodiment of the present application also includes: compressing the animation texture information according to the texture format supported by the preset game engine to obtain a compression result, wherein the compression result is compressed data of a number of bits corresponding to the texture format.

[0081] Specifically, the animation texture is imported into the UE engine, the texture format is the floating point image file exchange format (EXR), the 16-bit data format is selected as the texture compression format, and the animation texture information is compressed to obtain an accurate compression result.

[0082] Based on the above optional embodiment, by compressing the animation texture information according to the texture format supported by the preset game engine, a compression result is obtained, thereby reducing the storage space occupied by the animation texture and improving the performance of the game. By compressing the animation texture information, the size of the texture data can be reduced, and the burden on the GPU when loading and processing the texture can be reduced, thereby improving the running speed and efficiency of the game. At the same time, the compressed texture data can also reduce the download time and storage space of the game, providing players with a smoother and more efficient gaming experience.

[0083] Optionally, in step S22, mixing the animation map information with the vertex offset information to determine the target cloth display form of the virtual model includes:

[0084] Step S221, determining candidate vertex animation maps corresponding to a plurality of different cloth display states based on the animation map information, and determining candidate vertex color maps corresponding to a plurality of different cloth display states based on the vertex offset information;

[0085] Step S222 , obtaining a target cloth display form of the virtual model by mixing the candidate vertex animation map and the candidate vertex color map.

[0086] Specifically, based on the animation map information, Figure 7 Alternative vertex animation maps in the static state shown, such as Figure 8 Alternative vertex animation maps for the moving state shown, and Fig. 9 The alternative vertex animation map of the flag being inserted into the ground by the virtual character is shown. The alternative vertex color map is the baking result of the color map used for transition. In the UE engine, the 16-bit data format is also selected as the map compression format to ensure accuracy. Fig.10is a candidate vertex color map according to one embodiment of the present application, the candidate vertex color map in the static state is as follows Fig.10 shown. Fig.11 is another alternative vertex color map according to one embodiment of the present application, the alternative vertex color map in the moving state is as follows Fig.11 shown. Fig.12 is another alternative vertex color map according to one embodiment of the present application. The alternative vertex color map in the process of the flag being inserted into the ground by the virtual character is as follows: Fig.12 According to the candidate vertex animation map and the candidate vertex color map, the target cloth display form of the virtual model is obtained by mixing.

[0087] Based on the above optional embodiments, by determining the candidate vertex animation maps corresponding to a plurality of different cloth display states based on the animation map information, and determining the candidate vertex color maps corresponding to a plurality of different cloth display states based on the vertex offset information, and then mixing the candidate vertex animation maps and the candidate vertex color maps to obtain the target cloth display form of the virtual model, the corresponding cloth display form can be dynamically generated according to different cloth display states. By analyzing the animation map information and the vertex offset information, the appropriate candidate vertex animation map and the candidate vertex color map can be selected for different cloth states, thereby realizing the automatic transformation and adjustment of the cloth display form of the virtual model, thereby significantly improving the fidelity and realism of the virtual model, making the cloth display more vivid and interactive.

[0088] Optionally, in step S222, the target cloth display form of the virtual model is obtained by mixing the candidate vertex animation map and the candidate vertex color map, including:

[0089] Step S2221, selecting a first target vertex animation texture corresponding to a first state value and a second target vertex animation texture corresponding to a second state value from the candidate vertex animation textures, wherein the first state value and the second state value are boundary values ​​of a value range corresponding to a plurality of different cloth display states;

[0090] Step S2222, selecting a first target vertex color map corresponding to the first state value and a second target vertex color map corresponding to the second state value from the candidate vertex color maps;

[0091] Step S2223, performing interpolation calculation on the first target vertex animation map and the second target vertex animation map to obtain a first interpolation result;

[0092] Step S2224, performing interpolation calculation on the first target vertex color map and the second target vertex color map to obtain a second interpolation result;

[0093] Step S2225: Mix the first interpolation result and the second interpolation result to determine the target cloth display form of the virtual model.

[0094] Specifically, in the UE engine, the material function that originally restores the VAT needs to be modified. First, the function information is simplified. The embodiment of the present application only needs to use the simplified output information, which includes input time control, frame control, input normal, input vertex position offset, output normal, output vertex position offset, and UV channel for storing frame information. What needs to be adjusted in the material function is to replace the original texture with the texture array storing the animation information, and to copy an additional set of material nodes that restore the animation texture information, which are used to represent the first state value 0 and the second state value 1 respectively, select the first target vertex animation texture corresponding to the first state value 0 from the alternative vertex animation texture, and the second target vertex animation texture corresponding to the second state value 1, and select the first target vertex color texture corresponding to the first state value 0 and the second target vertex color texture corresponding to the second state value 1 from the alternative vertex color texture.

[0095] Any state can be stored between the first state value 0 and the second state value 1. The flag actually repeatedly transitions between 0 and 1. For example, the first state value 0 is the flag drooping state, and it needs to transition to the fluttering state of the second state value 1. After the flag completes the transition to the fluttering state of the second state value 1, the state in the first state value 0 can be switched to a shaking or other state. At this time, the transition from the second state value 1 to the first state value 0 is a new state performance.
