- 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.
