Title:
- Percentage-Closer Soft Shadows
Presenter(s)/Author(s):
Abstract:
One of the fundamental problems in computer graphics is generating accurate soft shadows from area light sources. Soft shadows provide valuable cues about the relationships between objects, becoming sharper as objects contact each other and more blurry (softer) the further they are apart.
