.SH "PARAMETERS"
.PP
\fImode\fR
.RS 4
Specifies whether front\- or back\-facing facets are candidates for culling\&. Symbolic constants
\fBGL_FRONT\fR,
\fBGL_BACK\fR, and
\fBGL_FRONT_AND_BACK\fR
are accepted\&. The initial value is
\fBGL_BACK\fR\&.

.SH "DESCRIPTION"
.PP
\fBglCullFace\fR
specifies whether front\- or back\-facing facets are culled (as specified by
\fImode\fR) when facet culling is enabled\&. Facet culling is initially disabled\&. To enable and disable facet culling, call the
\fBglEnable\fR()
and

\fBglDisable\fR
commands with the argument
\fBGL_CULL_FACE\fR\&. Facets include triangles, quadrilaterals, polygons, and rectangles\&.
.PP
\fBglFrontFace\fR()
specifies which of the clockwise and counterclockwise facets are front\-facing and back\-facing\&. See
\fBglFrontFace\fR()\&.
.SH "NOTES"
.PP
If
\fImode\fR
is
\fBGL_FRONT_AND_BACK\fR, no facets are drawn, but other primitives such as points and lines are drawn\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_ENUM\fR
is generated if
\fImode\fR
is not an accepted value\&.
