             How to Get Software for the Colours Module 
             ------------------------------------------------

The compressed tar file clr_sun.tar_z contains the SUN version of software 
for the Colours module of the ISC ITTI Computer Graphics and Visualization 
project, which is available via FTP (Don't forget to set binary mode) on: 

     Site                 IP Address           Directory

 [v2.mcc.ac.uk]        [130.88.100.13]        [.colours]

This FTP site is located on a VAX/VMS machine. An example of FTP session 
looks like this:

>ftp v2.mcc.ac.uk                    (connect to the FTP site)
name: user_name                      (type in user_name)
password: password                   (type in password)
ftp>dir                              (list available directories and files)
ftp>cd [.colours]                    (change directory to [.colours])
ftp>get readme.sun README            (retrieve the readme file)
ftp>binary                           (specify binary mode)
ftp>get clrs_sun.tar_z clr_sun.tar.Z (retrieve clr_sun.tar.Z in binary mode)
ftp>quit                             (quit from FTP session)

For inquiring the user_name and password, please contact:

It is recommended to put the retrieved file clr_sun.tar.Z in the directory 
/usr/local/gravigs. After that, you can type the Unix commands:

>uncompress clr_sun.tar.Z
>tar xvf clr_sun.tar

to extract the software in the directory /usr/local/gravigs/colours.

To enable the students to use the software ask your system manager to make the
the directory /usr/local/gravigs system wide acessible. Note using this scheme
has 2 advantages:

1) Subsequent modules e.g., standards will be stored in /usr/local/gravigs/standards,
2) The program listings contain details (for the students) to get copies of 
   the files.

The directory /usr/local/gravigs/colours has the following structure 
(each sub directory contains a README file): 

                     /usr/local/gravigs/colours/
                                   |
                  .----------------+----------------.
                  |                                 |
                demo/                           examples/

The directory /usr/local/gravigs/colours/demo contains all files related to 
the demonstration programs of the Colours module for SUN/SUNOS.

The directory /usr/local/gravigs/colours/examples contains all files related 
to the example programs of the Colours module for SUN/SUNOS.
