NAME
       gluDisk - draw a disk

C SPECIFICATION
       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).
