GLUDISK(3G)                                                                                      GLUDISK(3G)



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 subdi-vided subdivided
       vided 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).
