摘要

阐述了可视化技术中基于差分单元的形体表达、旋转变换以及图形消隐等方面的技术要点，推出了任意位置、任意角度剖切的剖视剖面技术，介绍了在实用商品软件中实现动态演示所必须的动画剪辑、动画合成以及动画播放等环节的技术思想，介绍了表现凝固相变、温度分布、流动、压力等多种物理场及其变化的技术。

Abstract

The method based on difference unit in FDM was used for graphic processing of solidification simulaton

that spared a lot of calculations needed on every unit.This paper introduced how to show the temperature distribution and the solidification of liquid

as well as the fluid flow in the casting mold etc.dynamiclly.The commercial software Intecast developed for graphic Processing of soliclification scinulation has been used successfully in many casting phants.
