Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of depth of field rasterization comprising: parameterizing a lens area, having regions, based on its shape; identifying lens regions in which a convex polygon to be rendered is not visible; culling, using a graphics processor, regions on a lens from which a convex polygon to be rendered is not visible; and inside testing only in regions wherein the polygon to be rendered is visible. 2. The method of claim 1 including on…
