摘 要:近年来计算机图形硬件性能不断提高,利用硬件来实现体绘制过程中的某些环节以获取交互的绘制速率成为可能,是目前体绘制的研究热点。描述了基于GPU的光线投射法、2D纹理映射法和3D纹理映射法等典型算法,给出了各类算法的分析与性能评价,最后实现相关算法并得出实验结果。With the ever-increasing development of graphics hardware in recent years, exploiting the fast rendering ability of modern graphics hardware to make the rendering process genuinely interactive has become available, and this method is the research hot spot. This paper described the typical algorithms about GPU-based volume rendering including were 3D texture-mapping hardware, 2D texture-mapping hardware, GPU-based ray casting, and then gave the kinds of algorithm analysis and performanee evaluation. Finally, came to the realization of related algorithms and presented some experimental results.
