Latest Patents
One of Covey's notable inventions is a method for converting non-zero winding to even-odd fill polygons. This invention discloses a method, apparatus, and article of manufacture for converting Non-Zero Winding to Even-Odd rule polygons, regardless of their shapes. Convex, concave, self-intersecting, and polygons with holes can all be converted from Non-Zero Winding to Even-Odd fill rule polygons. The invention accepts Non-Zero Winding fill polygons and computes all intersection points between the polygons. An initial intersection point between a first polygon and a second polygon is selected. The perimeter of either the first or second polygon is traced beginning from the selected intersection point. The trace switches between the perimeters of the first and second polygons as additional intersection points are reached during the tracing. The tracing is terminated when the selected intersection point is encountered by the tracing step. These steps are then repeated until all intersection points between the first and second polygons have been encountered.
Another significant patent is the immediate mode drawing interface for the construction of graphics. This invention discloses an apparatus, method, and article of manufacture for generating graphic images. In accordance with the present invention, an application program receives commands from a computer user via an input device and provides an output command stream to a plurality of renderer programs. The renderer programs selectively modify the output command stream and transmit the output command stream to a graphics peripheral device or to one or more of the other renderer programs.
