!Stellate (Demo Version)
‘Fortran Friends’, P.O.Box 64, Didcot, Oxon, OX11 0TH
telephone: +44 (0) 1235 834357
Introduction
!Stellate is an interactive program which creates uniform polyhedra and
their stellations. The full version allows you to save:
• Draw files of the stellation diagrams,
• Draw files of the 3D solids,
• data files for Stellate,
• PolyData for PolyDraw and PolyNet.
You can not save any files with this demo version and can only use the
supplied data files.
Machine and operating system requirements: Any Acorn computers using RISC-OS
operating systems: 3.XX, including networks and StrongARM with 288K spare
Application memory space.
Copyright and copying:
This program remains the copyright of ‘Fortran Friends’; this demo version
is given to you on the understanding that if you give a copy to anyone else
you will copy all the files, unchanged, including this one.
To get the Full Version:
Send a cheque for £20 payable to ‘Fortran Friends’ at the address above.
With the full version you can:
1. Save diagrams and 3D views as ‘Draw’ files or to !Draw for printing and
combining with others.
2. Save new polyhedra for reading back into !Stellate
3. save PolyData for !PolyDraw and !PolyNet.
4. Use more data files; the standard distribution data file contains
instructions for drawing 112 polyhedra.
5. Use your own new data files.
6. Read more documentation (see below)
7. Send us suggestions for improvements and report problems which we will
try to correct.

ReadMe for !Stellate
last updated 15 Feb 1998
!Stellate is an interactive program which creates uniform polyhedra and
their stellations using stellation diagrams. There are 112 pre-stored
polyhedra which are printed on the single A4 page enclosed in your manual.
!Stellate is written in the Fortran programming language by:
‘Fortran Friends’, P.O.Box 64, Didcot, Oxon OX11 0TH
tel: (01235) 834357
Machine and operating system requirements:
Any Acorn computers using RISC-OS operating systems 3.XX and at least 288K
available application workspace, including networks and StrongARM.
Copyright and copying:
Further details can be found in the file ‘Docs.CopyRight’
This program remains the copyright of ‘Fortran Friends’: it is licensed for
use at one site only; you may copy it to a backup floppy disc or to your own
hard disk but giving copies to others is illegal. Your registration number
is unique; any illegal copies found will be reported to the ‘Federation
Against Software Theft’ and you will be liable for prosecution.
Getting Started:
These instructions assume some knowledge of how to use an Acorn computer.
If you are a new user, more detailed instructions on how to copy files, use
the windows and the mouse can be found in the ‘User Guide’ manual for your
computer system. !Stellate is a RISC-OS compliant program which runs in the
Acorn Desktop and tries to conform to the operating conventions in the Acorn
Style guide; it supports Acorn interactive help.
Fortran Friends welcome comments and requests for new features for future
versions of this program.

Contents of the !Stellate Disc
This section is for reference only, you may never need to use it if you just
want to use the supplied data file to create and save stellations. All Draw
files on the distribution disc have been compressed using the standard
‘Squash’ program.
Top level directory
!Stellate - application
Docs - directory of documentation; ‘Docs.Readme’ explains what is in
each file
Products - software available from Fortran Friends

Skip to the section headed ‘Installation’ if this is the first time you have
looked at this file, and you are not interested in technicalities.
Within the !Stellate application, in addition to the usual files,
there is the directory ‘Resources’.
This has the standard Acorn files, ‘Messages’ and ‘Templates’;
there are several other files, which the program may change for you,
but which most users need not bother with.
‘Choices’ defines the initial settings of various options.
‘Colours’ defines all the colours used initially. The program can
change this file if the user changes the colours and then
asks to save the ‘Colours’ file before quitting the program.
‘Components’ definitions of components’ names, symmetry and interplanar
angles.
‘Register’ this file contains your name and registration information.
It must not be changed by the user.
‘Sprites’ sprites used in the tools pane of the 3D display window.
‘StellaList’ list of instructions for drawing stored polyhedra
--------------------------------------------------------------------
Installation:
1. Make a working copy on floppy disc. Store the original safely, in case
your working copy becomes damaged. Your license allows you to make a
single copy for your own use. If the disc supplied has been damaged and
will not copy, return it to us for a free replacement within 3 months of
purchase.
Use the ‘working’ copy for the rest of the instructions. You can run from
the floppy if you want to.
2. Installation on hard disc:
Make yourself a directory for storing your programs, with a name such as
‘Polyhedra’ and copy the contents of the floppy disc to it.
3. Read the Documentation.
Before trying to run the application, look at the file !Help file for
operating instructions, and in the directory ‘Docs.Reference’ for a glossary
of terms and an ‘Intro’ which explains how !Stellate uses stellation
diagrams to draw polyhedra. The sub-directory ‘Tutorials’ has more detailed
explanations with Draw file figures to help you understand better how to get
the most from !Stellate. The directory ‘TryThese’ has some suggested
activities and answers. You may want to print some of these out for future
reference.
4. Operating instructions:
Running instructions are in the file !Help of the application.
Acorn interactive help is supported.
5. Starting the program:
Double-click on the application !Stellate to start the program; this loads
an icon on to the icon bar. Click MENU when the pointer is over this icon to
see the options. Choose ‘info’ to see the program name, version number and
your registration number, which should be quoted in any correspondence with
‘Fortran Friends’. Click SELECT to choose a polyhedron.
6. Stopping the program:
Click MENU over the icon on the icon bar and choose the last option, ‘quit’.
If windows are hiding the icon bar, press key F12 while holding down the
SHIFT key, to bring the icon bar to the front of the windows.
7. Colour Changing:
You can change the colour used for particular faces of a polyhedron in some
of the display forms, and other colours of lines, or window backgrounds etc.
from the icon bar menu. If you try to do this and get an error message saying
‘Colour Picker module is not loaded’, then if you have a copy of the Acorn
Colour Picker Module load it using commands as described in the !Run file.
If you have not got this module you can get it off the Acorn User Cover Disc
for September 97 (in directory ‘System.!System.Modules.Toolbox’) or send a
blank disc plus return envelope and postage to ‘Fortran Friends’ at the
address above.
8. Possible Faults:
Error conditions we have thought about have ‘traffic sign’ windows which
should allow you to choose whether to stop the program or try to carry on.
If your working disc is damaged, you may find when you try to start the
program you merely get an ‘error window’ saying your user registration file
has been corrupted. Delete all the files from your working disc, and make a
new copy from your original disc.
If you find the program stops in an uncontrolled way, please try to write
down details of what you were doing just before the error, and send them to
us, preferably using the fault report form in file ‘Docs.FaultRep’.
If you have changed any of the !Stellate files, please supply copies of the
files on floppy disc which you were using when the error occurred.
