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.
