METHOD AND APPARATUS FOR ANTIALIASING A REGION OF A TWO-DIMENSIONAL DISTANCE FIELD REPRESENTING AN OBJECT

摘要

A method and apparatus antialias a region of a two-dimensional distance field representing an object. The two-dimensional distance field is partitioned into cells where each cell includes a method for reconstructing the two-dimensional distance field within the cell. A set of cells of the two-dimensional distance field associated with the region is identified and a set of pixels associated with the region is located. For each pixel, a set of components is specified. For each component, a distance is determined from the set of cells and then mapped to the antialiased intensity of the component of the pixel.
