Symbolic constants GL_FRONT, GL_BACK, and GL_FRONT_AND_BACK are accepted. The initial value is GL_BACK. Description glCullFace specifies whether front- or back-facing polygons are culled (as specified by mode) when polygon culling is enabled. Polygon culling is initially disabled. To enable and disable polygon culling, call the glEnable and glDisable commands with the argument GL_CULL_FACE. glFrontFace specifies which of the clockwise and counterclockwise polygons are front-facing and back-facing. See glFrontFace. Notes If mode is GL_FRONT_AND_BACK, no polygons are drawn, but other primitives such as points and lines are drawn. Errors GL_INVALID_ENUM is generated if mode is not an accepted value.
