All our programs run on any computer running RISCOS 3 4 or 5
including StrongARM and Iyonix.
They can also be run on PCs with Microsoft Windows
98 or later with a 300MHz Pentium/Celeron processor, 32MB RAM,
400Mb Hard Disk Space and a Direct X compatible graphics card by using
the 'Virtual Acorn' package.

Polyhedron plotting programs
Demo versions of all applications are available from this site
(see individual programs below).
These have only a few example data files, no other data files
can be loaded into them, or any file saved from them, but you can try all
the features on the screen.

interactive exploration of polyhedra from any one of over 140 data files
supplied. These consist of all the Platonic and Archimedean Solids and their
duals, together with the Kepler Poinsot and Johnson polyhedra, and some
prisms and antiprisms. Each polyhedron can be seen simultaneously in two
windows, as a 3D solid and as a planar net, both of which may be saved as a
Draw file and incorporated in the user's own documents.
Data may be saved for the ray tracing program
POVRAY, where you can download the RISCOS version. If you are using a PC
then you should start from the
official POVRAY site.

PolyDraw is no longer marketed because all of its functionality is
included in !PolySymm.

interactive creation of a planar net from a polyhedron data file.
There are 33 data files supplied, including all the Platonic and Archimedean
Solids and their duals, (identical to those supplied with !PolyDraw). The
net may be saved, with or without tabs, to a Draw file. The faces can be
coloured and decorated with the user's clip art before printing the net,
cutting it out and making it into a 3D model.

interactive investigation of the symmetries of polyhedra. There are
140 data files supplied, including all the Platonic and Archimedean Solids,
their duals, and the Johnson solids (identical to those supplied with
!PolyDraw). The polyhedron can be displayed in all the ways available in
!PolyDraw and selections made on classes of symmetries.
Results may be saved to a Draw file, printed or as PolyData including a
block of information on the symmetries.

(You will need a copy of the applications !PolyDraw or !PolyNet to use these)
All have a set of Draw files showing all the polyhedra on A4 size pages
- Disc 1
The duals of the Johnson Solids (92 files + 92 revised Johnson solids),
created by Paul Gailiunas.

Four of the solids had their definitions revised on 10 July 2001;

- Disc 2
Stellations, compounds, space fillers, mostly created by
G.Inchbald
with some from Fortran Friends (76 data files).

- Disc 3
The 59 Icosahedra; in addition to the Polydata for PolyDraw/Polynet,
this disc contains the data file for !Stellate, some explanation of the
naming scheme as defined in the 3rd edition of the booklet
The Fifty-Nine Icosahedra

by Coxeter et al, newly typeset by 'Fortran Friends' with Draw files showing all 59 stellations.
A few errors have been found in these diagrams,

revised pages.
Special offer with this disc you
have an option to buy
a copy of the 3rd edition of the booklet, published January 1999, by
Tarquin Publications, now marketed by
Tarquin Books.
- Disc 4 (The large amount of data requires
this disc to be High Density).
All the non-convex uniform polyhedra and their duals (106 data files) to
complement the convex uniform polyhedra which are standard with !PolyDraw.
click here to see some examples (31K)
Versions 3.21 of !PolyDraw and
1.15 of !PolyNet are needed to use all
of these.

interactive creation of uniform polyhedra their stellations, duals and
other polyhedra which can be made from up from 3 components using stellation
diagrams and stored inter-planar angles. The program comes supplied with more
than 120 pre-stored models,
click here to see them; you can either edit these or create your own entirely new ones.
The resulting polyhedra may be
saved in several formats, for later use in !Draw, !Stellate, !PolyDraw or
!PolyNet.
The process of stellation is explained here.

In preparation
More polyhedra data files for use with !PolyDraw or !PolyNet; let us know
what you want.
We sell the polyhedra plotting programs for £20 each (Polysymm is £30),
with a discount of £5 per program for all subsequent programs bought at the
same time.
For example:
Price for any one of !PolyDraw, !PolyNet, !Stellate: £20
Price for two, usually !PolyDraw and !PolyNet: £35
Price for all three (!Stellate, !PolyDraw, !PolyNet): £50
The additional data discs are £10 per disc of about 100 polyhedra and the
set of A4 pages of draw files showing all the polyhedra collected together.
Special offer When you buy disc 3,
which contains the data files to draw all the 59 icosahedra using
!PolyDraw/PolyNet or !Stellate,
normal price £10, you can have a copy of the 3rd edition of the booklet
The Fifty-Nine Icosahedra for an additional £5 (Tarquin price £6.95),
(Total cost, Disc 3 and the booklet £15).
Postage and packing are included for destinations in the UK. Please add £1
for postage to European Union countries and £2 elsewhere.

Updates to the most recent version (registered users only)
Updates are free via the Internet.
For updates by snail mail return your original program disc with £2
to receive the latest version, £3 for users outside the UK.
High Density Discs
We normally distribute one program per double density disc in the UK; we can
get two programs on a single high density disc, which saves us postage.
Please let us know if you cannot read high density (HD) discs when you send
your order.
Please note that payments should be sent with your order and
made in pounds sterling.
Cheques should be made payable to ‘Fortran Friends’ and sent
to:
Fortran Friends.
We can be contacted by email or phone here.
