draw
public void draw(float innerRadius, float outerRadius, int slices, int loops) 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 +z side of the disk is considered to be "outside" (see glu.quadricOrientation). 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 is turned on (with glu.quadricTexture), 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).
