GLCULLFACE(3G) GLCULLFACE(3G)

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

void glCullFace( GLenum 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.










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.








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








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.
