中文摘要： 随着三维互联网应用的迅速发展，网络环境下服饰动画的需求越来越多，现有的服饰动画技术难以满足其实时交互的要求。本项目以三维互联网应用为背景，以服饰动画的交互实时性和真实感为目标，研究服饰动画的关键技术，提出基于稀疏网格的物理-几何混合模型。通过建立刚性约束提高物理模型的表达能力，同时在稀疏网格上建立基于特征传递函数约束的几何模型，提高服饰动画的计算速度；在混合模型的计算方面，构造近似逆预条件子并将动力学方程分解，实现快速、稳定的并行求解；建立不同条件下的点簇结构表示，实现快速的碰撞检测与合理的碰撞响应。在三维互联网应用方面，提出服务器-客户端混合渲染的方式，并在此基础上部署服饰动画算法的并行处理方案，增强网络环境下服饰动画同步更新的实时性。本项目研究不仅为三维互联网应用中服饰动画的生成提供新的理论和方法，还对计算机图形学、虚拟现实等领域基础理论和技术提升具有重要意义。

英文摘要： As the rapid development of 3D Internet Applications, more and more demands on clothing animation in the network environment are raised. The existing clothing animation techniques are difficult to meet the requirements of the real-time interaction. This project will research on the key techniques of real-time clothing animation, which is based on the 3D Internet Applications, aiming to getting real-time and realistic clothing animation. A physical-geometrical hybrid model is established, in which the rigid constraints are used to improve the physical model's expression ability and geometric model based on the constraints of feature transfer function are constructed on the sparse grid. Approximate inverse pre-conditioner and the kinetic equation decomposition are constructed to achieve fast and stable parallel solution in calculation of hybrid model. Then the expression of point cluster structure is established to achieve fast collision detection and rational collision response under different conditions. In 3D Internet Applications, the Server-Client hybrid rendering architecture is presented and on this basis, parallel processing scheme for clothing animation algorithm is developed to enhance real-time of the synchronizating animation in network environment. The research results of this project will provide new
