摘要
结合Shear－Warp投影算法、优化的RLE体数据编码算法，进行基于RLE编码的动态快速等值面抽取算法研究。新的算法在没有硬件加速的条件下，使得绘制的速度得到很大地提高。该算法利用Shear－Warp数据投影中的体数据特点，实现了动态快速的等值面抽取，新算法的绘制速度在工程实践中基本可以达到实时的要求。
Abstract
A fast iso-surface extraction method was presented in a optimized RLE compression from shear-Warp algorithm.This new method has not any lose of resolution. And the rendering speed has been improved much. This algorithm has been used in our project on the PC system. A real time rendering speed achieved whitout any hardware accelerator adapter.
