gluDisk()
NAME
  gluDisk - draw a disk

SYNOPSIS
  void gluDisk(
	  GLUquadric* quad,
	  GLdouble inner,
	  GLdouble outer,
	  GLint slices,
	  GLint loops );

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

  inner
      Specifies the inner radius of the disk (may be 0).

  outer
      Specifies the outer radius of the disk.

  slices
      Specifies the number of subdivisions around the z axis.

  loops
      Specifies the number of concentric rings about the origin into which
      the disk is subdivided.

DESCRIPTION
  gluDisk() renders a disk on the z = 0 plane. The disk has a radius of
  outer, and contains a concentric circular hole with a radius of inner.  If
  inner is 0, then no hole is generated. The disk is subdivided around the z
  axis into slices (like pizza slices), and also about the z axis into rings
  (as specified by slices and loops, respectively).

  With respect to orientation, the +z side of the disk is considered to be
  "outside" (see gluQuadricOrientation()). This means that if the orientation
  is set to GLU_OUTSIDE, then any normals generated point along the +z axis.
  Otherwise, they point along the -z axis.

  If texturing has been turned on (with gluQuadricTexture()), texture
  coordinates are generated linearly such that where $ r = outer, the value
  at (r, 0, 0) is (1, 0.5), at (0, r, 0) it is (0.5, 1), at (-r, 0, 0) it is
  (0, 0.5), and at (0, -r, 0) it is (0.5, 0).
