| 摘 要： | 研究一种基于PC的体绘制技术,采用改进的光线投射算法,并以Visual C 6.0为开发环境,实现基于Open-GL光照模型的直接体绘制系统,突破现有三维体绘制大都基于专用图像工作站的现状,在微机上成功地实现从建立灰度体素模型、灰度体数据显示,包括灰度梯度计算、光照效应计算、投影合成显示等整个体绘制过程。并在Widows 2000平台下形成界面友好的人机交互通用化系统,从而较好地解决了体绘制生成图像质量和显示速度之间的深刻矛盾,达到快速有效完成三维图像显示的目的,并应用于外科手术支援系统中。

| Abstract: | This paper discusses volume rendering based on PC.The direct volume rendering system based on OpenGL illumination model adopts improved ray casting algorithms.This system is coded in Visual C 6.0 program language.Realizing that almost all the volume rendering functions on the microcomputer completely,which involves creating gray voxel-model.volume rendering(including ray-gradient calculation,shading,image projection and composing),then an universal system,which has a good interface and the function of man-machine alternation,is coming into being.The system can be used to solve the problem preferably between the quality of volume rendering images and the rendering speed. |
