Detailed Description
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The method aims to solve the technical problems that the efficiency of image real-time rendering processing is influenced and the requirement on equipment hardware is increased due to the fact that a large amount of hair assets need to be solved in the current image real-time rendering. The present embodiment provides an image rendering processing method, as shown in fig. 1, the method includes:
The preset specification hair can be preset according to actual requirements, for the embodiment, the preset specification can be used for judging the hair with the physical property not very complex, the rendering effect and the dynamics can be compared with the input time, and the hair can be completely simulated by an engine, so that a large amount of time cost is saved, and a good effect is achieved.
In the embodiment, the required hair asset and cloth calculation asset are manufactured, and the hair asset does not need dynamic calculation and is a static asset; while the cloth is a solution asset. For example, the required hair asset and cloth solution asset are made in Digital Content Creation (DCC) software, while the cloth is solved in external DCC software, considering that the solution software is a more real physical system, the calculation amount is large, the time is long, but the corresponding effect is relatively real; the direct cloth calculation in the illusion engine is only a simulation effect, so the difference between the final cloth dynamics result and the DCC calculation is huge, and the DCC calculation time is completely acceptable under the condition of considering the quality.
And 102, performing asset processing on the cloth calculation assets to obtain skeleton information.
Skeletal information may be included in the skeletal information that is created for the entire cloth solution asset. For the embodiment, the hair asset needs to be attached to the skeleton, so that the hair can move along with the cloth in the real-time rendering of the image, and a good dynamic effect is achieved under the condition that the rendering quality and the rendering speed are guaranteed, so that the asset processing needs to be performed on the cloth resolving asset to obtain corresponding skeleton information.
The binding file may contain a pre-set specification hair unresolved hair asset, and a skeleton to which the hair asset needs to be bound.
And step 104, configuring specified information of the cloth resolving assets.
The specified information comprises the unresolved hair asset and the binding file of the preset specification hair, and the hair asset and the binding file are further specified on the cloth resolving asset.
And 105, responding to the image rendering instruction, simulating the rendering effect of the hair asset, and integrating the simulated rendering effect of the hair asset and the image rendering effect of the cloth resolving asset according to the specified information of the cloth resolving asset.
The hair assets can be subjected to rendering effect simulation through the illusion engine in the embodiment to obtain a simulated rendering effect, on the premise that certain rendering quality is guaranteed, a large amount of time cost is saved, the efficiency of real-time rendering processing of images is improved, hardware dependence can be removed to a certain degree, and requirements for equipment hardware are lowered. According to the specified information of the cloth calculation asset, the simulation rendering effect of the hair asset and the image rendering effect of the cloth calculation asset are integrated, so that the hair can move along with the cloth under the condition that the hair has the binding file in the scene.
At present, cloth calculation and hair calculation are both realized in a point cache mode in a real-time rendering engine, however, the point cache is relatively difficult to control, the asset quantity is large, certain requirements also exist on hardware when the assets are loaded, and the hairs cannot be subjected to real-time dynamics calculation along with the point cache. Compared with the prior art, the image rendering processing method provided by the embodiment has the advantages that the hair assets of the preset specification hair which is not subjected to dynamic calculation are subjected to engine simulation, and then the dynamic simulation of an offline rendering level is obtained in real-time rendering. And the cloth result of external solution and the real-time simulation hair result are integrated in the real-time rendering, and the cloth and the hair are rendered in real time, so that the dynamic effect is good under the condition of ensuring the rendering quality and the rendering speed.
Further, as a refinement and an extension of the specific implementation of the above embodiment, in order to fully illustrate the implementation of the embodiment, another image rendering processing method is provided, as shown in fig. 2, and the method includes:
Optionally, the preset specification hair is hair with a length smaller than a preset length threshold and/or a hardness larger than a preset hardness threshold.
The preset length threshold and the preset hardness threshold can be preset according to actual requirements, and can be used for judging that the hair is not physically complicated, such as short hair and hard hair, compared with the situation that the hair needs to consume a large amount of time cost and the requirement on hardware is relatively high due to the huge amount of assets when the hair is subjected to dynamic calculation in a traditional mode, the method can be used for simulating the hair assets by a fantasy Engine (such as UE), and therefore the method has a good dynamic effect under the condition that the rendering quality and the rendering speed are guaranteed.
In order to obtain accurate skeleton information of the cloth calculation assets, the embodiment can perform asset processing on the cloth calculation assets by means of external three-dimensional modeling and animation software. For example, the cloth solution assets are imported into Maya software by way of a point cache (. Abc).
Optionally, step 203 may specifically include: copying models of a 0 th frame and a 1 st frame in point cache data of a cloth resolving asset, and performing hybrid space (blend space) processing on the two models of the 0 th frame and the 1 st frame, namely hybrid deformation processing; then copying a model of a 2 nd frame in the point cache data, and performing mixed space processing on the two models of the 2 nd frame and the 1 st frame; and by analogy, sequentially performing the last 1 frame in the point cache data to obtain the point cache data in a mixed space form.
For example, the models of the 0 th frame and the 1 st frame in the point cache are copied (there are two models at this time), and the two models are taken as BlendSpace once; then copying the model of the point cache frame 2, and making the model (the model of the frame 2) and the model of the frame 1 as a BlendSpace; and sequentially finishing the last frame to obtain the whole Blendspace, wherein the process can be realized by a plug-in.
And 204, recording key frames frame by frame for the point cache data in the mixed space form, creating skeleton points of a model of the cloth calculation asset, and exporting the cloth calculation asset in a preset file format.
All frames of the point cache data in hybrid space form are key frames, and the preset file format may be the FBX format. For example, the cloth calculation assets are imported into Maya software in a point cache mode, and the plug-in completes the mixing deformation and completes the process of the value K frame of blend space. And then directly inserting a root skeleton point, and binding the whole model on the root skeleton point to realize the creation of the skeleton point for the whole asset, and finally exporting the cloth resolving asset in a fbx format.
In this embodiment, the function of recording key frames frame by frame for the point cache data in the form of the mixed space is to determine a model used by each frame in the animation, and in addition, the key frames can correspond to a curve of a morphing target (MorphoTarget) in the illusion engine, so that the effect is the same as that in the point cache. Therefore, the key frames in the point cache data in the mixed spatial form are optionally in one-to-one correspondence with the key frames on the morphing target animation curve. For example, the keyframes on the MorphoTarget animation curve correspond to the keyframes of blend space in Maya, and there needs to be a one-to-one correspondence, so as to ensure that the effect of importing the converted point cache data in Maya into the illusion engine is consistent with the original point cache effect.
The binding file contains the kinetically unresolved hair asset, as well as the skeleton to which the hair asset needs to be bound. For example, hairs need to follow the movement of cloth, so the hairs need to be bound on bones, the hairs are recorded in a binding file, and the bones bound with the hairs are needed.
And step 206, the binding file is given to the constraint force asset slot of the hair asset in the scene.
For example, selecting a hair Asset in a ghost engine, then creating a Binding file, selecting hairs and bones to be bound in the Binding file, and giving the Binding file to a Binding Asset slot of the hairs in the scene; since the hair is made according to the model position in Maya, the position of the hair on the model is the same as in Maya.
And step 207, configuring specified information of the cloth resolving assets.
Optionally, step 207 may specifically include: calculating asset adding components for the cloth; the assembly is then used to deploy the hair asset into a corresponding slot in the cloth. For example, a "component" is "added" directly under the cloth, then the hair is placed directly onto the corresponding slot.
And step 208, responding to the image rendering instruction, and performing hair simulation on the unresolved hair assets by using a preset illusion engine.
And 209, according to the binding information of the hair asset and the skeleton in the binding file, moving the simulation rendering effect of the hair asset along with the image rendering effect of the cloth resolving asset.
For example, hairs are simulated in real time in the illusion engine, because the computation of solving hairs in DCC is huge and time consuming, and the current version of the illusion engine cannot support the introduction of hairs solved in DCC into the illusion engine through a point cache (. Abc), so hairs are simulated and computed in the illusion engine. The illusion engine performs hair simulation by using a built-in physical engine, and specifically comprises the following operations: "Enable Simulant" is selected in the "physics" option of the hair asset, at this time, the simulation mode can be selected in the following "Niagara Solver", in the scene, under the condition that the hair has the binding file, the hair can follow the cloth to move.
The embodiment will integrate the externally resolved cloth results and the real-time resolved hair results in real-time rendering, and a specific integrated example process may be as shown in fig. 3. The hair assets (not dynamically resolved) in the DCC tool and the cloth resolved assets in the DCC tool are imported into a fantasy engine for integration, so that the hair is moved along with the cloth according to the binding file.
In order to illustrate the specific implementation process of the above embodiments, the following application examples are given, but not limited thereto:
for example, as shown in fig. 4, a model of a mink fur coat with which a character in a game can perform character movements is shown. At present, for image rendering, the dynamic effect is achieved, the mode that cloth resolving and hair resolving are both point cache is achieved in a real-time rendering engine, however, the point cache is not well controlled, the hair asset quantity of the mink velvet is huge, certain requirements also exist for hardware when the assets are loaded, and the mink velvet cannot be resolved in real-time dynamics along with the point cache.
In order to solve the above technical problems, according to the image rendering processing method provided in this embodiment, for the case where the physics such as short hair and hard hair of mink hair is not very complicated, the image rendering processing method can be simulated by a phantom engine, so that a good dynamic effect is achieved while the rendering quality and the rendering speed are ensured.
Specifically, a manufactured mink velvet hair asset and fur clothing cloth resolving asset is obtained, and the hair asset does not need to be resolved dynamically and is a static asset; whereas sweater cloth is a solution asset. And importing the cloth resolving assets to Maya software through point cache to obtain point cache data, and converting the point cache data into a form of a mixed space. And then, recording key frames frame by frame for the point cache data in the form of the mixed space, and creating skeleton points of a model of the cloth resolving asset so as to derive the sweater cloth resolving asset in the FBX format. The function of recording key frames frame by frame for the point cache data in the form of mixed space is to determine the model used by each frame in the animation, and in addition, the key frames can correspond to the curve of the deformation target in the illusion engine, so that the effect is ensured to be the same as that in the point cache.
After the processing of the sweater cloth resolving asset is finished, a binding file of the mink plush hair asset and the skeleton is created based on the skeleton points, the binding file is sent to a constraint force asset slot of the mink plush hair asset in the scene, and the hair asset and the binding file are designated on the sweater cloth resolving asset. And finally, performing mink fur simulation on unresolved hair assets by using the illusion engine during image rendering, and moving the simulation rendering effect of the mink fur assets along with the image rendering effect of the sweater cloth resolving assets according to the binding information of the hair assets and the skeleton in the binding file, so that the mink fur is moved along with the sweater cloth (the mink fur sweater can move consistently with the game role), and further achieving a good dynamic rendering effect of the game images.
Compared with the prior art, the image rendering processing method provided by the embodiment has the advantages that the hair assets which are not dynamically calculated by the hair in the preset specification are subjected to engine simulation, and then the dynamic simulation of an offline rendering level is obtained in real-time rendering. And the cloth result of external solution and the real-time simulation hair result are integrated in the real-time rendering, and the cloth and the hair are rendered in real time, so that the dynamic effect is good under the condition of ensuring the rendering quality and the rendering speed.
