Poisson-Disc Sampling - Jason Davies

WebMulti-View Soft Shadowing (MVSS) (Bavoil, 2011) was created by nVidia. This approach uses multiple shadow maps from different points on an area light source. These points are chosen using a Poission disk sampling pattern. For each pixel, each shadow map is queried and an average over all maps is taken.

WebAug 28, 2024 · Shadow Mapping 还存在硬阴影（Hard Shadow）的问题，因为现实世界的影子往往是软阴影（Soft Shadow）。. 一个现实观察是，当投影物与阴影之间的距离越远，则阴影越软（如下图：笔尖阴影由于与笔尖的距离较近，因此阴影边缘较为锐利；而远处笔身阴影则因与笔身距离较远，阴影边缘较为发散且模糊）。
