GLCULLFACE() MachTen Programmer’s Manual GLCULLFACE()

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 counter-
clockwise 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 exe-
cuted between the execution of glBegin and the correspond-
ing execution of glEnd.
