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
