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  ini‐
       tially 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
