Shadow map silhouette revectorization
Vladimir Bondarev · 2014
Shadow Map Silhouette Revectorization (SMSR) is a two-pass filtering technique inspired by Jorge Jimenez's MLAA [Jimenez et al. 2011] which aims to improve the visual quality of a projected shadow map by concealing the perspective aliasing with an additional umbra surface. In most cases undersampled areas result in a higher shadow silhouette edge quality. However, the technique is relatively new and has plenty of room for improvement.
