基于数据场特征的直接体绘制方法

Volume Rendering Based on Data Field Characteristics

论文在数据点分类的基础上,采用不同的方式计算表面采样点和内部采样点的颜色,改进了物质单一的数据场的光线投射体绘制方法。对物体模型内部的各数据点,采用一种简单的颜色映射经验模型来求解,简化了数据场内部数据点颜色的计算,减少了计算量,提高了绘制效率。

This paper improves on raycasting method of single substance data field,by using different means to comput-er surface and internal data points' color,based on the data points classification.In allusion to internal data points of model,we adopt a simple color mapping model,simplify internal data points' color computation,reduce quantity of com-putation and improve the rendering efficiency.
