NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

       void glCullFace(
               GLenum mode );

PARAMETERS    [Toc]    [Back]

       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    [Toc]    [Back]

       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    [Toc]    [Back]

       If  mode  is  GL_FRONT_AND_BACK,  no facets are drawn, but
       other primitives such as points and lines are drawn.

ERRORS    [Toc]    [Back]

       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().

       glGet() with argument GL_CULL_FACE_MODE
