| 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.

1. A computer graphics system having one or more central processing units (CPUs), one or more memories, and one or more communication interface, the system further comprising: a geometric data structure having a plurality of vertex positions defining one or more polygons, the polygons defining a wireframe representation of a geometric object, each of the vertex positions further associated with one or more sets of vertex color information; a color table data structure having one or more fill colors to be rendered between two or more of the vertex positions on a rendering of the geometric object; and a shade table data structure that associates a substitute color to each of the fill colors, at least two of the fill colors having the same substitute color.
