!PolyNet (Demo Version)
'Fortran Friends', P.O.Box 64, Didcot, Oxon, OX11 0TH
telephone: +44 (0) 1235 834357
Introduction
!PolyNet is an interactive program which creates planar nets from files
containing data on how to draw polyhedra. The full version allows you to
save Draw and datafiles; you cannot save any files with this demo version,
you can only use the supplied datafiles, and cannot change the 'Choices' file.
Machine and operating system requirements: Any Acorn computers using RISC-OS
operating systems 3.XX, including networks and StrongARM.
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 as 'Drawfiles' and data files for use later.
2. Use more datafiles: any of the Platonic and Archimedean solids and duals.
3. Use your own new datafiles
4. Read more documentaion (see contents of full version directory Docs below)
5. Send us suggestions for improvements and report problems which we will
try to correct.

Introduction
!PolyNet is an interactive program which creates planar nets from files
containing data on how to draw polyhedra, such as that used in !PolyDraw.
Machine and operating system requirements:
Any Acorn computers using RISC-OS operating systems 3.XX,
including networks and StrongARM.
Copyright and copying:
Further details are in the file Docs.CopyRight.
This program remains the copyright of 'Fortran Friends': it is licensed to
you for single use 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. !PolyNet 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.

--------------------------------------------------------------------
Installing !PolyNet
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.
Note: If you are installing !PolyDraw at the same time, you need not copy
the datafiles supplied in the directory 'Examples' of !PolyNet, since they
are all stored in the sub-directories 'dat0' and 'dat1' of !PolyDraw.
3. Read the Documentation.
Before trying to run the application, look at the file !Help file for
operating instructions and in the sub-directory 'Docs' which includes
suggested activities and worksheets, a glossary of terms and example
Draw files. You may want to print these out for future reference.
Operating instructions:
Running instructions are in the file !Help of the application; Acorn
interactive help is supported.
Starting the program:
1. Double click on the application !PolyNet to start the program, and load
an icon on to the iconbar. Click the mouse 'MENU' button when the pointer is
over this icon to see the options. Select 'info' to see the program name,
version number and your registration number, which should be quoted in any
correspondence with 'Fortran Friends'.
2. Drag any of the files from the 'Examples' directory on to the icon to
open a window showing the polyhedron drawn as a 3D solid. Click with the
'Select' button over the first face which you want in the planar net. This
opens the 'net' window and shows you that face. Then click on the next face
you want, which should be adjacent to one of the ones you have drawn
previously. When you have clicked on all the faces a small window appears
allowing you to save a Drawfile. See !Help for further instructions.
Stopping the program:
Click 'MENU' over the icon on the iconbar and choose the last option, 'quit'.
Displaying your own data files:
The format of the data files is defined in the file Docs.FormData which
lists all the possible lines of the file. You need not make all the lines,
but the first line must have the string ':name ' as the 1st 6 characters,
and the last line must begin ':end'. The faces must be described in
clockwise direction as they are seen from inside the polyhedron. If they are
not, the results are unpredictable, usually, the face is missing from the 3D
plot.
For example:
:name my new cube
:comment designed by me on 22 June 97
:solidf 6 4
4 1 2 3 4 1
4 4 5 6 1 2
4 2 1 6 7 7
4 8 3 2 7 5
4 8 5 4 3 3
4 6 5 8 7 4
:solidv 8
0 0.8 0.58
-0.8 0 0.58
0 -0.8 0.58
0.8 0 0.58
0.8 0 -0.58
0 0.8 -0.58
-0.8 0 -0.58
0 -0.8 -0.58
:end
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 !PolyNet.Docs.FaultRep.
If you have changed any of the !PolyNet files, or the fault is in reading a
new polyhedron of your own, please check carefully that you have listed the
face vertices in the correct order before contacting us. The usual symptom
of this is that the face with incorrect vertices is not plotted in the 3D
window. Please supply copies of the files on floppy disc which you were
using when the error occurred.
