快速辐射度算法的实现研究

Implementation Research of Fast Radiosity Algorithm

当虚拟场景发生变化时,扩展的逐步求精算法作为一种快速的辐射度算法,大量减少了重新计算辐射度所花费的时间。对扩展的逐步求精算法进行研究,并利用OpenGL对算法进行了实现。通过在实验中对虚拟场景的表面反射率和几何属性进行改变,获得了一些证明算法有效性的数据,从而验证了该算法的有效性。

Extended progressive refinement method as a fast algorithm of radiosity minimize the reeomputation time after any virtual scene modification. In this paper, the extended progressive refinement method is studied and implemented in the way of OpenGL. Then the data which can prove the efficiency of the algorithm by changing scene reflectivity and scene geome- try during experiment is obtained. In this way, the method is proved to be efficient.
