基于体素模型的优化体绘制技术

Voxel-based optimized volume rendering techniques

直接体绘制技术因可绘制数据场中包含的内部结构形成较高图像质量而倍受青睐,但大量计算导致的绘制速度慢严重制约着其在大规模数据场交互绘制方面的应用。对现有算法进行优化是其发展方向之一。对目前基于体素模型的体绘制关键环节优化技术进行了概括,并分析了进行优化的主要思路,为进一步应用、改进这些技术提供参考。

Direct volume rendering is a popular method of rendering high quality images from volume data. It is difficult to obtain interactive volume rendering of the huge data sets,because of the extreme computational expense. The optimized volume rendering techniques in the key algorithmic processes in the recent years were summerized and the main ideas were analysed. The results were useful for further employment and improvement.
