Volume rendering algorithm based on Monte Carlo method
一种基于蒙特卡罗方法的体绘制算法*

In order to resolve the rendering speed and imaging quality problem in 3D Visualization of medical image, introduced a novel volume rendering algorithm based on Monte Carlo method. According to the given probability density function, selected and rendered a point cloud of random samples or its subset. Mainly presented the algorithm to efficiently visualize the large volume data sets. And obtained the trade-off between image quality and interactivity by using progressive refinement. Given a fixed image resolution, the results of experimentation show that the time complexity and the memory complexity of the algorithm are better than previous methods, and imaging quality of the algorithm meets the demand of real-time rendering.
