一个通用简单局部光照模型的设计和实现

Design and Implementation of a Simple Local Gencral Purpose Lightness ModeI

本文介绍了一个通用简单局部光照模型的设计思想和实现算法,包括物体的表示,隐藏面的消除,明暗度的计算,并提出了用软件实现无级灰度显示的方法。该模型以时间和分辩率为代价,在微机上实现了通常工作站才提供的单个点光源下真实物体的显示。

T-his paper introduc s the design idnas and the implemen ation of algori hams about a simple local lightness model,including the representa- oin of objects.the removing of hidden surface and the computation of greyness. Meanwhile,a method of displaying greyness is given by software.At the cost of time and resolution,the model implements the display of objects on micro- computer under single light source which ordinary orkstation supplys
