摘要
体绘制技术是一种能够准确反映出数据内部信息的可视化技术.本文介绍了3种常用体绘制算法:光线投射算法,足迹算法和错切_变形算法的基本思想,在此基础上比较了它们的性能并对它们的改进作了进一步的讨论,最后给出了结论并对这3种算法的前景作出了的展望.
The technique of volume rendering is a kind of volume visualisation technique, which can reflect the inside information of the data. This paper introduces three kinds of algorithm for volume rendering: ray-casting algoritlun, splatting algorithm and shearwarp algorithm.The differences of their performances are compared and their improvements are also discussed here. Then rome resuits are presented and their perspective are given in the end.
