We present an OpenGL-assisted visibility culling algorithm to improve the rendering performance of large polygonal models. Using a combination of hier...

We present a sub-linear algorithm to compute the set of back-facing polygons in a polyhedral model. The algorithm partitions the model into hierarchi...

This paper presents an algorithm to estimate what parts of the surrounding environment are visible from each of many sample points on a surface, whic...

We describe a method of producing ray-traced images of 2D environments at interactive rates. The 2D environment consists of a set of disjoint, convex...

Hybrid geometry- and image-based modeling and rendering systems use photographs taken of a real-world environ- ment and mapped onto the surfaces of a...
