| Description | Variance Shadow Maps (VSMs) were first introduced in [Donnelly and Lauritzen 06] as an alternative to bilinear percentage closer filtering (PCF) to speed up rendering of smoothed shadows. The algorithm is relatively inexpensive, easy to implement, and very effective in rendering shadows with large penumbra regions. However, VSM has one ma jor drawback—apparent light-bleeding— which occurs when two or more shadow casters cover each other in light-space. This chapter will show techniques that help to reduce the light-bleeding artifacts in VSM. Book Name: GPU Pro 360 |
