GLCULLFACE(3G)                                   OpenGL 3.3                                   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.

ASSOCIATED GETS
       glIsEnabled() with argument GL_CULL_FACE


       glGet() with argument GL_CULL_FACE_MODE

SEE ALSO
       glEnable(), glFrontFace()
