GLenum GetCullFace (   )  const [inline]

Returns which faces are culled by OpenGL.

GLenum GetFrontFace (   )  const [inline]

Returns the orientation of front-facing polygons.

Activates the State. If the State is enabled, the corresponding piece of OpenGL state is enabled and its value is set, if appropriate. If the State object is disabled, the corresponding piece of OpenGL state is disabled. Implements State.

void SetCullFace (  GLenum  cullFace  )  [inline]
