Syntax

SUB _glCullFace (BYVAL mode AS _UNSIGNED LONG)

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 Template:KW and Template:KW commands with the argument Template:KW. Facets include triangles, quadrilaterals, polygons, and rectangles.

Template:KW specifies which of the clockwise and counterclockwise facets are front-facing and back-facing. See Template:KW.

If mode is Template:KW, no facets are drawn, but other primitives such as points and lines are drawn.
