Description
glMaterial assigns values to material parameters. There are two matched sets of
material parameters. One, the front-facing set, is used to shade points, lines, bitmaps,
and all polygons (when two-sided lighting is disabled), or just front-facing polygons
(when two-sided lighting is enabled). The other set, back-facing, is used to shade
back-facing polygons only when two-sided lighting is enabled. Refer to the glLightModel
reference page for details concerning one- and two-sided lighting calculations.
