NAME

6       gluDisk - draw a disk
7

C SPECIFICATION

9       void gluDisk(GLUquadric* quad, GLdouble inner, GLdouble outer,
10                    GLint slices, GLint loops);
11

PARAMETERS

13       quad
14           Specifies the quadrics object (created with gluNewQuadric()).
15
16       inner
17           Specifies the inner radius of the disk (may be 0).
18
19       outer
20           Specifies the outer radius of the disk.
21
22       slices
23           Specifies the number of subdivisions around the z axis.
24
25       loops
26           Specifies the number of concentric rings about the origin into
27           which the disk is subdivided.
28

DESCRIPTION

30       gluDisk renders a disk on the z = 0 plane. The disk has a radius of
31       outer and contains a concentric circular hole with a radius of inner.
32       If inner is 0, then no hole is generated. The disk is subdivided around
33       the z axis into slices (like pizza slices) and also about the z axis
34       into rings (as specified by slices and loops, respectively).
35
36       With respect to orientation, the +z side of the disk is considered to
37       be ``outside'' (see gluQuadricOrientation()). This means that if the
38       orientation is set to GLU_OUTSIDE, then any normals generated point
39       along the +z axis. Otherwise, they point along the \-z axis.
40
41       If texturing has been turned on (with gluQuadricTexture()), texture
42       coordinates are generated linearly such that where r = outer, the value
43       at (r, 0, 0) is (1, 0.5), at (0, r, 0) it is (0.5, 1), at (\-r, 0, 0)
44       it is (0, 0.5), and at (0, \-r, 0) it is (0.5, 0).
