> 中文摘要: 科学可视化中,体绘制是非常重要的一类方法,它的基本操作是色彩合成.本文对色彩合成过程中透明度的变化序列进行了考察,提出了一个基于透明度基准区与视点无关的透明度标尺,并将各类物质的透明度转换为基于透明度标尺的步长,使成像时的色彩合成过程省略许多重复计算,从而提高可视化效率.
Abstract:Color composition is a fundamental step for direct volume rendering in scientific visualization.A new technique is proposed in this paper for compositing colors.By this method,a transparent degree ruler based on a transparent degree unit is built,and it is independent of the view point.After the transparent degrees of all media are transferred to relative steps based on the transparent degree ruler, a new compositing' color method is presented to eliminate a lot of repeated calculations to improve the efficiency of visualization.
