METHOD AND APPARATUS FOR DETERMINING AN ANTIALIASED INTENSITY OF A COMPONENT OF A PIXEL FROM A TWO-DIMENSIONAL ADAPTIVELY DISTANCE FIELD

摘要

A method and apparatus determine an antialiased intensity of a component of a pixel from a two-dimensional distance field representing an object. A set of sample points in the two-dimensional distance field is associated with the component of the pixel. A distance is determined from the two-dimensional distance field and the set of sample points and then mapped to the antialiased intensity of the component of the pixel.
