Screen Space Curvature and Ambient Occlusion
Original language description
Curvature plays an important role in computer graphics. It helps us to better understand surfaces of various objects. We often deal with a discrete geometry. However, the exact curvature can only be evaluated for analytical surfaces and not for discrete ones. Existing algorithms estimate curvature for discrete geometry with a certain precision. Most of the time, the performance of those algorithms is low and they are not intended to be used in real time applications. Our target is to have a real time curvature estimation that can be used during interactive geometry changes, like in a virtual sculpting. This paper proposes a screen space technique which estimates two principal curvatures and their directions at interactive rates. Final curvature can be used for an ambient occlusion estimation. The proposed solution is created to fit directly into existing rendering pipelines.
