Abstract:
1. A method comprising: tessellating a polygon in camera space into a set of micropolygons so that each micropolygon maps to a region of screen space that does not cross boundaries of specified screen space regions; displacing each vertex of each micropolygon by a corresponding displacement amount in the direction of a normal at the vertex to form a set of displaced micropolygons, wherein the displacement amount for each vertex location of each micropolygon is based on a specified set of displacement values; and sub-dividing each displaced micropolygon into two or more new micropolygons, if boundaries projected from the specified screen space regions intersect the displaced micropolygon generating an image for display on a display device, wherein one or more pixels of said image are at least partially determined using the displaced micropolygons or the new micropolygons.
