glCullFace(3G)glCullFace(3G)NAMEglCullFace - specify whether front- or back-facing facets can be culled
GLenum 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.
DESCRIPTIONglCullFace() 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 glEn‐
able() 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().
