void glCullFace( GLenum mode )

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.

 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.

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

 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.
