Abstract
A computer system, method, and article of manufacture for shading graphical objects and/or displays is disclosed. A graphical geometric data structure has a plurality of vertex positions defining one or more polygons, typically triangles. In a preferred embodiment, the polygons define a wireframe representation of a geometric object. Each of the vertex positions is associated with one or more sets of vertex color information. A color table has one or more fill colors to be rendered (shaded) between two or more of the vertex positions on a rendering of the geometric object. These colors can uniformly vary between the vertices of the triangle over the entire surface. A substitute color is associated with each of the fill colors so that at least two of the fill colors are associated with the same substitute color.
