摘要
计算机仿真中常用到仿真单元位位姿和形状变换。文章假设在变形时不产生新的表面或互相重叠的情况下 ,采用曲线坐标系描述仿真单元体内每一点位置 ,并讨论了选用坐标系的两种方法 。
Shape trasformation of simulation unit in virtual environment is usually used in computer simulation. Provided that there is not any new surface or surface overlapping when deforming, this paper describes each position of the point in the simulation unit by two types of curve coordinate. The coordinate selection method is disscussed.And the research on transformation velocity and acceleration is helpful to mobile simulation.
