GLCULLFACE(3G) UNIX Programmer's Manual GLCULLFACE(3G)
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 ini-
tial 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 com-
mands with the argument GL_CULL_FACE. Facets include trian-
gles, quadrilaterals, polygons, and rectangles.
glFrontFace specifies which of the clockwise and counter-
clockwise 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 exe-
cution of glEnd.
