GLCULLFACE(3G)															    GLCULLFACE(3G)

NAME
       glCullFace - specify whether front- or back-facing facets can be culled

C SPECIFICATION
       void glCullFace( GLenum mode )

PARAMETERS
       mode  Specifies	 whether   front-  or  back-facing  facets  are  candidates  for  culling.   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 facets are culled (as specified by mode) when facet culling is enabled. Facet culling is
       initially  disabled.  To enable and disable facet culling, call the glEnable and glDisable commands with the argument GL_CULL_FACE.  Facets
       include triangles, quadrilaterals, polygons, and rectangles.

       glFrontFace specifies which of the clockwise and counterclockwise facets are front-facing and back-facing.  See glFrontFace.

NOTES
       If  mode is GL_FRONT_AND_BACK, no facets 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.

       GL_INVALID_OPERATION is generated if glCullFace is executed between the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS
       glIsEnabled with argument GL_CULL_FACE
       glGet with argument GL_CULL_FACE_MODE
