Abstract
A computer graphics painting system defined in terms of three dimensional graphics and texturing mapping. A three dimensional drawing primitive, most commonly a polygonal mesh, is directed along a path specified by a tablet, mouse, or other input stream. The primitive is transformed to sequential locations along the stroke in three dimensional space. At each location the primitive is processed with texture mapping techniques and blended into the frame buffer for real-time display. The brush primitive may take many forms to achieve a wide variety of painting effects and styles. The polygonal mesh form may also be active in conforming to any underlying surface or model data, thus enabling real-time painting of three dimensional objects.
