基于CUDA的直接体绘制算法的研究

irect Volume Rendering is an important research content in Scientific Visualization, the traditional direct volume rendering render slowly and interact poorly. With the development of hardware ,The research of Direct Volume Rendering that use graphics hardware to accelerate render become the research hotspot CUDA provides a simple and easy development environment ,which can be used to calculate parallel graphics processors. This paper discusses the basic principles of direct volume rendering ,it is also discusses algorithm of Direct Volume Rendering based on CUDA ,which improved greatly rendering speed.
