摘要

本文通过介绍Roberts算法的基本思想

给出了经过改进、拓广的新算法。新算法比原有的算法在速度方面更快

在数学表示方面更简单

在应用方面更广泛。利用该算法我们编制了程序TDFEP

并能使它在微机上运行。利用该程序我们可以从空间中不同的位置观察三维物体

并绘制其三维透视图。三维透视图在校核有限元计算中的原始数据方面占有重要地位。它能大大提高整个计算的工作效率。

Abstract

In this paper

the basic idea of Roberts algorithm is presented

and a new improved algorithm is proposed. The new algorithm is faster

simpler and more applicable to many problems than Roberts’ one. Based on this new algorithm

program TDFEP is developed

which is executable on microcomputer. With this program

a three dimensional object can be viewed from any direction in the space

and 3D-perspectives are formed. 3D-perspectives take an important role to check original data of finite element calculation

which can improve the efficiency of the whole calculation process obviously.
