  • System for distinguishing front facing and back facing primitives in a computer graphics system using area calculations in homogeneous coordinates
    Patent number: 6304265
    Abstract: The present invention directed to a method and apparatus for distinguishing between front facing and back facing polygons in a computer graphics environment. The method determines whether the polygon is a triangle, a quadrilateral, or a polygon with more than four vertices. Then the method computes the area of the polygon using a first formula, if the determining step determines the polygon to be a triangle. If the determining step determines the polygon to be a quadrilateral, then the method computes the area of the polygon using a second formula. Finally, if the determining step determines the polygon to be a polygon with more than four vertices, then the method computes the area of the polygon using a third formula. Each of the formulas—the first formula, the second formula, and the third formula—differ from one another.
