A method renders a mesh constructed of polygons representing a graphics model one at the time to accentuate geometric features of the mesh. At least one additional polygon is generated at each edge of each polygon of the mesh. Each additional polygon has a predetermined orientation, size, and color. The predetermined orientation of the generated polygons is 180° with respect to the polygon if the polygon is a back-facing polygon to accentuate silhouettes. The predetermined orientation of the generated polygon is a first threshold angle with respect to the polygon if the polygon is a front-facing polygon to accentuate ridges, and the predetermined orientation of the generated polygon is a second threshold angle with respect to the polygon if the polygon is a front-facing polygon to accentuate valleys. |
