NAME
gluDisk - draw a disk

C SPECIFICATION

PARAMETERS

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).

## new disk slices

How do I create new disk slices taking space from an existing slice? Right now I have slice 6 (/usr) with 16G. I'd like to create slices 5 (/opt) and 7 (/export/home) and steal space from slice 6. Thanks

## two loops

Hi, how can I use "for" to have two loops : this is my script : for i in (A B C) do for j in (a b c) do echo \$i\$j done done #End I want to print out Aa Ab Ac .... But I have error message : syntax error at line 1 : `(' unexpected Many thanks before. How should I use "for" ??

## Resize root disk slices

I have a Sun box running Solaris 9. My root disk was slices too small when it was installed and I am now at 99% capacity for my root partition. Is it possible, and if so how?, to increase the size of slice 0 and decrease the size of slice 7?? Thanks! Current partition table...

## trying to learn for loops, and arrays at the same time

Ok, I've already completed the task this is for, but now I'm trying to go back and find more eloquent solutions for future reference. I have a report I've generated that is formatted like this: 1033 1 1079 4 1453 5 2205 6 1933 7 461 8 646 9 1655 12 975 13 1289 14 The first number is...

## For Loops

Hi everyone, I have a question regarding for loops. I am writing a BASH shell script that will contain multiple loops. These loops all involve looping with a count: for (( a=0; a <=10; a++ )); do echo \$a done If none of my multiple loops relate to each other throughout the script,...

## Problem counting unique disks/slices

I want to create a unique listing of slices/disks from a large list that will have duplicates. Here is a sample of the input file. #array.txt Disk4:\s93 Disk4:\s93 Disk4:\s94 Disk4:\s95\s96\s97 Disk4:\s93 Disk4:\s95\s96\s103 Disk4:\s93 Disk4:\s93 Disk4:\s95\s96\s105 Disk4:\s93...
