以环境贴图的形式对复杂光照进行采样在计算机图形学中受到了广泛的关注。最近在这一领域的工作表明，从光和BRDF的产品中提取样本产生比其他采样策略更上级的结果。然而，现有的方法在这方面只考虑个别帧，并没有利用动画的连贯性。本文介绍了一种动态环境地图光照的顺序采样方法。我们的算法有效地从照明和BRDF的产品采样，同时利用时间相干性。我们证明了显着的性能优势，超过现有的方法。
Sampling complex illumination in the form of environment maps has received a lot of attention in computer graphics. Recent work in this area has demonstrated that drawing samples from the product of light and BRDF produces superior results to other sampling strategies. However, existing methods in this area consider only individual frames, and do not take advantage of coherence in animations. In this paper, we introduce a sequential sampling approach for dynamic environment map illumination. Our algorithm efficiently samples from the product of illumination and BRDF, while exploiting temporal coherence. We demonstrate significant performance benefits over existing methods.
