摘要
本文分析了多个几何体三维图形数据的存贮管理和各种几何变换等问题;借助于IBM PC(0520)汇编语言,利用BIOS中断和DOS功能调用,解决了多个几何体的单一操作和整体操作问题,实现了各种几何变挟的交互控制;采用分页技术,消除了屏幕动画显示过程中的闪烁,使动画显示具有可靠的连续性。
This paper analyses problems of three dimensional solids data st rue ture managenement and various geometric transformation. With help of IBM PC(0520) assembly language, assumes BIOS interrupts vectors and DOS function calling, solves the problems of single operation and whole operation about solids. So the interactive controls of any geometric tranformation is achieved. Others, the system cleares screen's flicker by using divide-page method. So, the trustworthy continuity is obtained in the process of dynamic display.
