GLenum orientation )

PARAMETERS
       quad         Specifies the quadrics object (created with gluNewQuadric).

       orientation  Specifies   the   desired  orientation.  Valid  values  are
                    GLU_OUTSIDE and GLU_INSIDE.

DESCRIPTION
       gluQuadricOrientation specifies what kind of orientation is desired  for
       quadrics rendered with quad. The orientation values are as follows:

       GLU_OUTSIDE    Quadrics  are  drawn  with  normals pointing outward (the
                      initial value).

       GLU_INSIDE     Quadrics are drawn with normals pointing inward.

       Note that the interpretation  of  outward  and  inward  depends  on  the
       quadric being drawn.
