Review on GPU-based volume rendering

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 performance evaluation.Finally,came to the realization of related algorithms and presented some experimental results.
