glCullFace(3G) OpenGL Reference 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.
