摘要

环境遮挡是光线追踪中使用了几十年的照明模拟方法。然而，为了获得高分辨率的环境遮挡，大量的采样时间消耗限制了其发展。提出了一种利用采样过程中相邻像素共享信息来减少采样次数的算法。通过引入新星方法，与以往的方法相比，我们得到了很大的改进。

A shared pixel ambient occlusion method in ray tracing

Ambient occlusion is an illumination simulation approach used in ray tracing for decades. However, huge consume of multiple sample times, for a high re-solution, in ambient occlusion restricts its development. We propose an algorithm decreasing the sample times with adjacent pixels shared information in sampling process. By introducing this nova approach, we get a big improvement when comparing to previous methods.
