glCullFace — specify whether front- or back-facing polygons are culled

C Specification

void glCullFace(GLenum mode);



Specifies whether front- or back-facing polygons are culled. 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 polygons are culled (as specified by mode) when culling is enabled. To enable and disable culling, call glEnable and glDisable with argument GL_CULL_FACE. Culling is initially disabled.

glFrontFace specifies which of the clockwise and counterclockwise polygons are front-facing and back-facing.


If mode is GL_FRONT_AND_BACK, no polygons are drawn, but other primitives such as points and lines are drawn.


GL_INVALID_ENUM is generated if mode is not an accepted value.
