由于传统方法对多模态三维动画逼真度建模存在缺陷，导致多模态三维模型的真实性比较差，为了改善三维动画模型的质量，提出一种基于虚拟现实技术的多模态三维动画逼真度建模仿真方法。采集现实场景图像、音频、视频等数据组成多模态模型，并设计相应的数据库；利用其他模块调用相关数据，并通过模型库展示场景，将多模态模型展示在用户面前；利用虚拟现实技术建立三维动画模型，设置以人眼为依据的视场角，完成对多模态三维动画的建模。在此基础上，对模型进行渲染处理，并在渲染流水线最后控制模型的渲染率，优化模型的逼真度。实验结果表明，所提出的方法渲染速度快，模型逼真度能够满足用户需求，整体质量得到了提升。

Due to the defects of traditional methods in modeling the fidelity of multi-modal 3D animation, the authenticity of the multi-modal 3D animation model is relatively poor. In order to improve the quality of the 3D animation model, a multi-modal 3D animation fidelity modeling and simulation method based on virtual reality technology is proposed. This paper collects data such as images, audio and video of real scenes to form a multi-modal model and designs the corresponding database. By using other modules to call relevant data and presenting scenarios through the model library, the multi-modal model is shown to users. The 3D animation model is established by using virtual reality technology, and the field of view based on the human eye is set to complete the modeling of multi-modal 3D animation. On this basis, the model is rendered and the rendering rate of the model is controlled at the end of the rendering pipeline to optimize the fidelity of the model. The experimental results show that the proposed method has a fast rendering speed, the model fidelity can meet the user's requirements, and the overall quality is improved.
