Patent ID: 6917369

Claim:
A method for rendering a region of a distance field representing an object, wherein the distance field is partitioned into a set of cells, each cell comprising a set of distance samples and a method for reconstructing the distance field within the cell using the distance samples, comprising: selecting a set of source cells from the set of cells of the distance field to render the region; representing each source cell in the set of source cells as a geometric element in a world coordinate system, each geometric element associated with a texture map, the texture map comprising distance samples of the corresponding source cell; transforming each geometric element from the world coordinate system to a pixel coordinate system; texture mapping, using the distance samples, each geometric element to determine a distance for each component of each pixel associated with the geometric element; and mapping the distance of each component of each pixel to an antialiased intensity of the component of the pixel to render the region of the distance field representing the object.
