中文摘要：

提出了一种基于入射光复用的滤波算法，该算法以蒙特卡罗路径跟踪为基础，将采样得到的入射光照保存，然后根据一定的标准，复用采样点周围的入射光做滤波。该算法可在较短时间内获得平滑的图像，具有较广的适应性。

英文摘要：

An incident radiance driven filter in the context of Monte Carlo global illumination was proposed. Based on Monte Carlo path tracing, the sample radiance was averaged by a filter using the adjacent radiances. The proposed filter can produce high quality images fast.
