WebVisibility culling aims at quickly rejecting invisible geometry before actual hidden-surface removal is per-formed. This can be accomplished by only drawing the visible set, that is, the subset of primitives which may contribute to at least one pixel of the screen.

Exact from-region visibility culling

WebJul 27, 2003 · From-region visibility culling is considered harder than from-point visibility culling, since it is inherently four-dimensional. We present a conservative occlusion culling method based on factorizing the 4D visibility problem into horizontal and vertical components. The visibility of the two components is solved asymmetrically: the …
