USING TRANSPARENT DEGREE RULER TO COMPOSITE COLORS IN VOLUME RENDERING
体绘制中基于透明度标尺的色彩合成方法

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.
