glCullFace.3G - Man Page

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

C Specification

void glCullFace(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.


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.
