The gluDisk function draws a disk.
void gluDisk(
GLUquadricObj * qobj,
GLdouble innerRadius,
GLdouble outerRadius,
GLint slices,
GLint loops
);
The gluDisk function renders a disk on the z = 0 plane. The disk has a radius of outerRadius, and contains a concentric circular hole with a radius of innerRadius. If innerRadius 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 positive 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 positive z-axis.
If texturing is turned on (with gluQuadricTexture), texture coordinates are generated linearly such that where r = outerRadius, 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).
