多种动态模拟和复杂三维动画控制的框架结构

本文提出了一种新的适用于多种动态模拟和复杂三维动画控制的面向对象的框架结构，它采用混合层次模型，其角色按部件层次组织其静态结构，角色中包含有决定其形状、样式和行为变化的属性，它按类的层次结构定义，属性的动态赋值通过引进的动态约束机制实现.该框架结构已用于SIMUKIT──用于多种动态模拟视觉效果自动生成的集成工具环境中，并在SGI工作站上初步实现，实验表明该框架结构对解决多种动态模拟生成是可行的.

A FRAMEWORK FOR MULTIPLE DYNAMIC SIMULATION AND COMPLEX 3D ANIMATION CONTROLS

In this paper, the authors present an object-oriented framework which adapts to a variety of dynamic simulation and complex 3D animation controls. The framework is based on a hybrid model. The static structures of actors are combined as part hierarchies.The attributes of actors determine their shape, appearance, time-varying behavior and are defined as class hierarchies. The attributes's dynamic assignment is implemented by dynamic constraint mechanism. This framework has already been used in SimuKit-an integrated environment for automatic generation of visual effect for multiple dynamic simulation. It is basically implemented on SGI workstation. It is feasible to implement multiple dynamic simulation by this framework.
