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
