glCullFace

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

Signature

glCullFace( GLenum ( mode ) )-> void
glCullFace( mode )

Parameters

VariablesDescription
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 counterclockwise 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.
