glCullFace3x
Specify whether front- or back-facing facets can be culled
C specification
void glCullFace( GLenum mode )
Parameters
- mode
-
Specifies whether front- or back-facing facets are candidates for culling. Symbolic constants
GL_FRONT,GL_BACK, andGL_FRONT_AND_BACKare accepted. The initial value isGL_BACK.
Overview
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.
GL_INVALID_OPERATION is generated if glCullFace is executed between the execution of glBegin and the corresponding execution of glEnd.
