glCullFace - specify whether front- or back-facing facets can be culled
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.
