基于物理模型的交互式服装实时动画

Physically Based Real-time Animation of Interactive Garment

提出了一种用于实现基于物理模型的交互式服装实时动画的方法。由于基于物理的服装模型本身与碰撞检测涉及大量的计算,因此随人体运动的交互式服装实时动画一直是一个具有挑战性的课题。为了提高模拟性能,首先简化经典的“质点-弹簧”模型,并利用“半刚性-复杂摆”模型经向与纬向约束分开计算的优点;其次,在服装与人体之间的碰撞检测采用椭圆包围盒的检测方法,并根据碰撞检测本身存在的局部性,通过时间与空间相关性来加速。实验结果证明,本文方法与传统的方法相比,大量减少了计算,完全可以实现随人体运动的交互式服装实时动画。

In this paper, a new real-time interactive garment simulation based on physical model is proposed. The animation of interactive garment of moving body in real-time has always been a great challenge in the field of computer graphics because the computation of the garment model and collision detection is very lumping. In order to improve the performance, we firstly simplify the classical ＂ particle-spring＂ model, and utilize the advantages of the processing separately of longitudinal and latitudinal restriction in ＂semi-rigid-complex pendulum＂ model ; According to temporal and geometric coherence, we accelerate the collisions detection between the body and the garment because the collision detection is very local. The experimental results show that the computational complexity reduce rapidly and the movement of interactive garment can be simulated in real-time.
