摘要
体绘制技术可将难于理解的二维数据场转化成直观的图像,作为一种最具前景的科学计算可视化技术在医学影像方面有着极强的实用意义。由于体绘制算法需要强大的计算能力,在通常的PC系统上难以实现满足交互式应用的绘制速度,因此阻碍了其普及。研究PC系统上的快速体绘制技术,无疑具有重要的意义。本文使用Shear-Warp的体绘制算法,并利用Intel公司的SSE2扩展指令对整个绘制过程进行加速,实现了基于中高档桌面PC系统平台的快速体绘制应用。
As a promoting science computing visualization technology, volume rendering, which can be used to change difficult understandable 3D data into images, is of great practical value in the application of medical images processes. Because of the needing of powerful computing capacity, it is difficult to satisfy the speed of interactive application of volume rendering on desktop PC machines. The study of the application of volume rendering on PC is meaningful for wide use of it. In this paper, taking use of SSE2 extensive commands and Shear -Warp algorithm, we accelerated the volume rendering process to realize fast volume rendering application on PC.
