Definitions for "Gouraud Shading"
(v) A rendering method that uniformly adjusts the value of a surface color based on the relationship of the light source to normals calculated for each vertex of the model. Gouraud shading is sometimes called smooth shading because the vertex normals allow interpolation of shading values across multiple polygons representing the facets of a curved surface.
The process of shading 3D polygons to create realistic environments. Without gouraud shading, the graphics on screen would resemble chicken wire. (4/99)
(which is the shading method used when FastRendering) determines the color value for all the vertices of a polygon. The color is then gradated between the vertices. The color of a Gouraud shaded object is based on the color of the object's polygons, and the color, position and intensity of the light sources.
