基于物体坐标系的三维图形数据表示
The three-dimensional object representations by object coordinates
【摘要】 :鉴于世界坐标系定义的空间往往远大于被描绘物体的几何尺寸、导致了数据冗余、分辨率低 .提出用物体坐标系表示三维图形 ,使存储空间减小 ,分辨率提高 ,并可提高运算速度 .
【Abstract】 The world coordinates’ scope is much bigger then the object of been represented.This lead to larger redundancy and lower resolving power.Set forth the representations of three-dimensional object by object coordinates.It can reduce redundancy and provide higher resolving power and speed.
