摘要： 针对传统几何造型呆板静态的缺点,在人体头部模型中提出采用基于简化弹簧质点系统的物理建模技术。研究了简化弹簧质点系统的质点受力计算和方程组求解技术。根据人体头部特点,作特征参数化处理,并将头表面简化成由弹簧连接的线弹性质点系统。经实验,该变形模型能实时计算描述动态变形过程,达到了较好的仿真显示效果。

Abstract: Aimed to the stiff and static disadvantages of traditional geometric modeling, this paper adopts a kind of physical-based geometric modeling, simple spring-mass system, in the human head deformable model. Particle force and equation groups computing methods are researched. Based on the characteristics of human head, the characteristic parameters are managed and the head surface is predigested into simple spring-mass system. Proved by the experiment, this system can stimulate the deformation change in time and has good display result.
