Abstract

Depth of field may be rasterized by culling half-space regions on a lens from which a triangle to be rendered is not visible. Then, inside tests are only performed on the remaining unculled half-space regions. Separating planes between the triangle to be rendered and the tile being processed can be used to define the half-space regions.
