[0047] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.
[0048] To address the technical challenges of real-time image rendering, which requires processing large amounts of hair assets, thus impacting both efficiency and hardware requirements, this embodiment provides an image rendering processing method. Figure 1 As shown, the method includes:
[0049] Step 101: Obtain the fabric assets and the un-calculated hair assets of the preset specifications.
[0050] The preset specifications for hair can be set in advance according to actual needs. In this embodiment, the preset specifications can be used to determine hair that is not physically complex. In terms of rendering effect, dynamics and time invested, it can be completely left to engine simulation, thereby saving a lot of time costs to achieve a good effect.
[0051] In this embodiment, the required hair assets and cloth simulation assets are created. The hair assets do not require dynamics calculation and are considered static assets; the cloth assets are simulation assets. For example, the required hair assets and cloth simulation assets are created in Digital Content Creation (DCC) software, while the cloth is simulationd in external DCC software. Considering that the simulation software is a more realistic physical system, the computational load is large and the time is long, but the corresponding effect is more realistic. Cloth simulation directly in Unreal Engine is only a simulation effect; therefore, the final cloth dynamics result differs greatly from the DCC simulation. Considering quality, the DCC simulation time is perfectly acceptable.
[0052] Step 102: Perform asset processing on the fabric assets to obtain skeleton information.
[0053] The skeletal information may include skeletal-related information created for the entire cloth solution asset. In this embodiment, the hair asset needs to be attached to this skeleton so that the hair can follow the movement of the cloth in real-time image rendering, thereby achieving good dynamic effects while ensuring rendering quality and speed. Therefore, the cloth solution asset needs to be processed to obtain the corresponding skeletal information.
[0054] Step 103: Based on the skeletal information, create a binding file for the hair assets and the skeleton.
[0055] The binding file may contain hair assets with pre-defined specifications that have not been resolved, as well as the skeleton that needs to be bound to the hair assets.
[0056] Step 104: Configure the specified information for the fabric calculation asset.
[0057] The specified information includes the hair assets and binding files of the hair in the preset specification that have not been resolved, and then the hair assets and binding files are specified on the cloth resolution assets.
[0058] Step 105: In response to the image rendering command, simulate the rendering effect of the hair asset, and integrate the simulated rendering effect of the hair asset with the image rendering effect of the cloth asset according to the specified information of the cloth asset.
[0059] In this embodiment, the rendering effect of hair assets can be simulated using Unreal Engine to obtain a simulated rendering effect. While ensuring a certain level of rendering quality, this saves significant time costs, improves the efficiency of real-time image rendering processing, and reduces hardware dependence, lowering the requirements for device hardware. Based on the specified information of the cloth solving asset, the simulated rendering effect of the hair asset is integrated with the image rendering effect of the cloth solving asset, so that in the scene, if the hair has a binding file, it can move with the cloth.
[0060] Currently, cloth and hair calculations are implemented in real-time rendering engines using point caching. However, point caching is relatively difficult to control, involves a large number of assets, and places certain hardware demands when loading assets. Furthermore, hair cannot be dynamically calculated in real-time following the point cache. The image rendering method provided in this embodiment, compared to existing technologies, allows the engine to simulate hair assets with preset specifications and no dynamic calculations, thereby achieving offline-level dynamic simulation in real-time rendering. Moreover, it integrates externally calculated cloth results and real-time simulated hair results in real-time rendering, rendering both cloth and hair in real time, achieving excellent dynamic effects while ensuring rendering quality and speed.
[0061] Furthermore, as a refinement and extension of the specific implementation methods of the above embodiments, and to fully illustrate the implementation methods of this embodiment, another image rendering processing method is provided, such as... Figure 2 As shown, the method includes:
[0062] Step 201: Obtain the fabric assets and the un-calculated hair assets of the preset specifications.
[0063] Optionally, the preset hair specifications are hairs with a length less than a preset length threshold and / or a hardness greater than a preset hardness threshold.
[0064] The preset length threshold and preset hardness threshold can be preset according to actual needs. They can be used to determine whether the hair is physically simple, such as short hair or stiff hair. Compared with the traditional method of dynamic calculation for such hair, which requires a lot of time and the large number of assets puts relatively high demands on the hardware, the method of this embodiment can let the Unreal Engine (such as Unreal Engine, UE) simulate such hair assets, so as to have good dynamic effects while ensuring rendering quality and rendering speed.
[0065] Step 202: Import the cloth solution asset through point cache to obtain point cache data.
[0066] To obtain accurate skeletal information for the cloth-rendered assets, this embodiment utilizes external 3D modeling and animation software for asset processing. For example, the cloth-rendered assets can be imported into Maya software using a point cache (.abc) file.
[0067] Step 203: Convert the point cache data into a mixed space format.
[0068] Optionally, step 203 may specifically include: first, copying the models of frame 0 and frame 1 from the point cache data of the cloth solution asset, and performing a blendspace processing on the two models of frame 0 and frame 1, i.e., blend deformation processing; then copying the model of frame 2 from the point cache data, and performing a blendspace processing on the two models of frame 2 and frame 1; and so on, until the last frame in the point cache data is obtained, thus obtaining point cache data in the form of blendspace.
[0069] For example, copy the models of frame 0 and frame 1 from the point cache (there are two models at this time), and perform a BlendSpace on these two models; then copy the model of frame 2 from the point cache, and perform a BlendSpace on it (the model of frame 2) and the model of frame 1; repeat this process until the last frame to obtain the entire BlendSpace. This process can be implemented by a plugin.
[0070] Step 204: Record keyframes frame by frame for the point cache data in the mixed space form, and create the skeleton points of the cloth solution asset model, and export the cloth solution asset in a preset file format.
[0071] All frames in the BlendSpace point cache data are keyframes, and the default file format can be .FBX. For example, when importing cloth solved assets into Maya via point cache, the plugin can keyframe the BlendSpace value after performing blend deformation; this process can also be done by the plugin. Then, a root bone point can be directly plugged in, and the entire model can be bound to this root point to create bone points for the entire asset. Finally, the cloth solved asset can be exported in .fbx format.
[0072] In this embodiment, recording keyframes frame-by-frame for the point cache data in mixed space format serves to determine the model used in each frame of the animation. Additionally, it corresponds to the curve of the MorphoTarget in Unreal Engine, ensuring the effect is identical to that in the point cache. Therefore, optionally, the keyframes in the point cache data in mixed space format correspond one-to-one with the keyframes on the MorphoTarget animation curve. For example, keyframes on the MorphoTarget animation curve correspond to keyframes in Maya's BlendSpace; this one-to-one correspondence is necessary to ensure that the effect of the point cache data converted in Maya and imported into Unreal Engine is consistent with the original point cache effect.
[0073] Step 205: Create a binding file for hair assets and bones based on skeletal points.
[0074] The binding file contains the hair assets that have not yet been dynamically solved, as well as the bones that need to be bound to the hair assets. For example, if the hair needs to follow the movement of the cloth, it needs to be bound to a bone. The binding file records the hair and the bones that need to be bound to the hair.
[0075] Step 206: Provide the binding file to the constraint asset slot of the hair asset in the scene.
[0076] For example, in Unreal Engine, select the hair asset, then create a binding file. In the binding file, select the hair and bones that need to be bound, and then assign the binding file to the binding asset slot of the hair in the scene. Since the hair in Maya is based on the model's position, the position of the hair on the model is the same as in Maya.
[0077] Step 207: Configure the specified information for the fabric calculation asset.
[0078] Optionally, step 207 may specifically include: adding a component to the cloth solver asset; and then using the component to configure the hair asset to the corresponding slot on the cloth. For example, you can directly "Add Component" - "groom" under the cloth and then directly place the hair into the corresponding slot.
[0079] Step 208: In response to the image rendering command, perform hair simulation on the unresolved hair assets using the default Unreal Engine.
[0080] Step 209: According to the binding information between the hair asset and the skeleton in the binding file, move the simulated rendering effect of the hair asset to follow the image rendering effect of the cloth solution asset.
[0081] For example, hair is simulated in real-time within Unreal Engine. This is because calculating hair in DCC is computationally intensive and time-consuming, and current versions of Unreal Engine do not support importing hair calculated in DCC via point cache (.abc). Therefore, hair is simulated and calculated within Unreal Engine. Unreal Engine uses its built-in physics engine for hair simulation. Specifically, in the hair asset's "Physics" options, check "Enable Simulate." Then, you can select the simulation mode in "NiagaraSolver." If the hair has a rigging file in the scene, it will move with the cloth.
[0082] This embodiment integrates externally calculated cloth results and real-time calculated hair results in real-time rendering. A specific integration example can be found as follows: Figure 3 As shown, the hair assets (without dynamics) and the cloth assets from the DCC tool are imported into Unreal Engine for integration, enabling the hair to follow the cloth movement based on the binding file.
[0083] To illustrate the specific implementation process of the above embodiments, the following application examples are given, but are not limited thereto:
[0084] For example, such as Figure 4 The image shows a model of a mink sweater, which game characters can wear for movement. Currently, to render this dynamic effect, both cloth and fur calculations need to be implemented in a real-time rendering engine using point caching. However, point caching is relatively difficult to control. The amount of mink fur assets is enormous, and loading these assets places certain demands on the hardware. Furthermore, the mink fur cannot be dynamically calculated in real-time following the point caching.
[0085] To address the aforementioned technical issues, the image rendering method proposed in this embodiment allows for simulation using Unreal Engine for physically simple objects such as mink fur, which has short, stiff hair. This approach ensures both rendering quality and speed while achieving excellent dynamic effects.
[0086] Specifically, the process begins by acquiring the mink fur assets and sweater fabric assets. At this stage, the fur assets do not require dynamics calculation and are considered static assets; the sweater fabric assets are calculated assets. The fabric assets are then imported into Maya software via a point cache to obtain point cache data, which is then converted to a blend space format. Next, keyframes are recorded frame-by-frame on the blend space point cache data, and the skeletal points of the fabric asset model are created. The sweater fabric assets are then exported in .FBX format. The purpose of recording keyframes frame-by-frame on the blend space point cache data is to determine the model used in each frame of the animation and to correspond to the curves of the deformation target in Unreal Engine, ensuring the effect is consistent with the point cache.
[0087] After the sweater fabric asset is processed, a binding file is created based on the skeletal points to bind the mink fur asset and the skeleton. This binding file is then assigned to the constraint asset slot of the mink fur asset in the scene, and the fur asset and binding file are specified on the sweater fabric asset. Finally, during image rendering, Unreal Engine is used to simulate mink fur on the unprocessed fur asset. According to the binding information between the fur asset and the skeleton in the binding file, the simulated rendering effect of the mink fur asset moves in sync with the image rendering effect of the sweater fabric asset. This achieves the effect of the mink fur following the movement of the sweater fabric (the mink sweater can move in sync with the game character's movement), resulting in a good dynamic rendering effect for the game image.
[0088] The image rendering method provided in this embodiment, compared with the prior art, hands over the hair assets with preset specifications and undynamically solved for hair dynamics to be simulated by the engine, thereby obtaining offline rendering-level dynamic simulation in real-time rendering. Furthermore, it integrates the externally solved cloth results and the real-time simulated hair results in real-time rendering, and renders the cloth and hair in real time, achieving excellent dynamic effects while ensuring rendering quality and rendering speed.
[0089] Furthermore, as Figures 1 to 2 The specific implementation of the method shown in this embodiment provides an image rendering processing device, such as... Figure 5 As shown, the device includes: an acquisition module 31, a processing module 32, a creation module 33, a configuration module 34, and a rendering module 35.

[0096] In a specific application scenario, the processing module 32 is further used to copy the models of the 0th and 1st frames in the point cache data, and perform a mixed space processing on the two models of the 0th and 1st frames; copy the model of the 2nd frame in the point cache data, and perform a mixed space processing on the two models of the 2nd and 1st frames; and so on, until the last frame in the point cache data is obtained, thus obtaining point cache data in mixed space form.
[0097] In specific application scenarios, the keyframes in the point cache data of the hybrid spatial form correspond one-to-one with the keyframes on the animation curve of the deformed target.
[0098] In a specific application scenario, the creation module 33 is specifically used to create the binding file based on the skeleton points. The binding file contains the hair asset and the skeleton that needs to be bound to the hair asset. The binding file is then given to the constraint asset slot of the hair asset in the scene.
[0099] In a specific application scenario, the configuration module 34 is specifically used to add components to the fabric calculation assets; and to use the components to configure the hair assets onto the corresponding slots of the fabric.
[0100] In a specific application scenario, the rendering module 35 is specifically used to simulate hair on the hair asset using a preset Unreal Engine; according to the binding information between the hair asset and the skeleton in the binding file, the simulated rendering effect of the hair asset moves along with the image rendering effect of the cloth solution asset.
[0101] In specific application scenarios, the preset specification hair refers to hair with a length less than a preset length threshold and / or a hardness greater than a preset hardness threshold.
