Abstract:
1. A method for reducing the number of sample points tested for rendering a screen space tile of an image, the method comprising: constructing a trajectory of a primitive in a three dimensional coordinate system comprising a screen space dimension, a lens dimension, and a time dimension; determining low and high bounding planes in the three dimensional coordinate system for the screen space tile of the image by using three dimensional points of the trajectory of the primitive; constructing a bounding volume for the screen space tile which is to be rendered by using the low and high bounding planes in the three dimensional coordinate system for the screen space tile, wherein the bounding volume extends between the low and high bounding planes in the three dimensional coordinate system that are determined as a function of the trajectory of the primitive, and wherein the bounding volume overlaps a portion of the screen space tile; and excluding from testing, one or more sample points which are located within the screen space tile, and which are not overlapped by the bounding volume.
