ABSTRACT:
A method detects border tiles or border pixels of a primitive corresponding to an object to be displayed on a display screen. The detecting includes: calculating the number of border tiles or pixels covered by an edge of the primitive; identifying a plurality of vertices that divide the edge in a plurality of segments of equal length; calculating coordinates of the vertices; and associating a tile or pixel with the coordinates of each vertex. The number of vertices for the edge is greater than or equal to the number of border tiles or pixels.
