软体多局部破碎特效研究

Soft Body Simulation with Multiple Local Fracturing Effects

基于物理的软体仿真与动画是计算机图形学的研究热点之一,但大多数方法计算复杂度较高,难以获得实时性交互.文中在虚节点算法基础上,提出了一种软体多局部破碎特效行为描述算法,该算法通过判别组成软体物理模型的质点受力、弹簧结构损伤情况,对模型进行局部几何拓扑重构,较好地描述了软体局部破碎行为.此外,在闭合压力模型理论基础上,结合质点弹簧系统,实现了一个实时交互的软体仿真平台.实验证明,整个软体仿真及多局部破碎特效过程可以获得稳定、实时交互、具有物理真实感的效果.

Physical based Soft Body simulation and animation attract the heart of the researchers in computer graphics for a long time,but most methods need huge complicated computation and they could not get a real-time interactive result.This paper presents a novel algorithm to describe the local fracture effects of Soft Body based on virtual node algorithm.The algorithm firstly checks the conditions of the springs and the masses that form the geometrical structure of the object,and then it makes a local topology reconstruction for the simulation,the whole process works well for the multiple local fracture effects.Experiments show that the entire simulation process with multiple local fracture effects can be physical realistically at interactive speeds.
