glFrontFace specifies which of the clockwise and counterclockwise facets are front-facing and back-facing. See "glFrontFace" .
ERRORS
GL_INVALID_ENUM is generated if mode is not an accepted value.
GL_INVALID_OPERATION is generated if glCullFace is called between a call to glBegin and the corresponding call to glEnd.
ASSOCIATED GETS
