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.

ASSOCIATED GETS

       glIsEnabled() with argument GL_CULL_FACE

       glGet() with argument GL_CULL_FACE_MODE
