机器人及其作业环境的几何实体是三维的,而仿真的屏幕图象是二维的。因而三维图形仿真的一个关键技术就是把物体的三维坐标变换为微机屏幕上的二维坐标。本文分析了三维图形变换的理论基础并解决了坐标变换冗长繁锁的矩阵计算问题。本文运用计算机代数系统使复杂的数—符运算得以简化。
The geometric entities of the robot and its working environment are three-dimensional, while the simulated screen image is two-dimensional. Therefore, a key technology of three-dimensional graphics simulation is to transform the three-dimensional coordinates of the object into two-dimensional coordinates on the screen of the computer. This paper analyzes the theoretical basis of three-dimensional graphics transformation and solves the problem of long and complicated matrix calculation of coordinate transformation. In this paper, the use of computer algebra system to simplify the complex number - operator to be simplified.
