{{PageDescription}}
'''_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 {{KW|_glEnable}} and {{KW|_glDisable}} commands with the argument {{KW|_GL_CULL_FACE}}. Facets include triangles, quadrilaterals, polygons, and rectangles.
{{KW|_glFrontFace}} specifies which of the clockwise and counterclockwise facets are front-facing and back-facing. See {{KW|_glFrontFace}}.
{{PageNotes}}
If {{Parameter|mode}} is {{KW|_GL_FRONT_AND_BACK}}, no facets are drawn, but other primitives such as points and lines are drawn.
{{PageErrors}}
{{KW|_GL_INVALID_ENUM}} is generated if {{Parameter|mode}} is not an accepted value.
