    NAME

    glCullFace
    
    - 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, 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. GL_INVALID_OPERATION is generated if glCullFace is executed between the execution of glBegin and the corresponding execution of glEnd.
