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.!PolyDraw

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.
and shaded images with shadows like this made later.

A demo version may be downloaded from here (size 417K)
PolyDraw is no longer marketed because all of its functionality is included in !PolySymm.
!PolyNet
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.

A demo version may be downloaded from here (size 130K)
!PolySymm
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.

Extra Data Discs
(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.
click here to see four examples (8K)
Four of the solids had their definitions revised on 10 July 2001; click here to download the updates (4.1K). - Disc 2
Stellations, compounds, space fillers, mostly created by G.Inchbald with some from Fortran Friends (76 data files).
click here to see some examples (34K) - 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 booklet
The Fifty-Nine Icosahedra
by Coxeter et al, and Draw files showing all 59 stellations.
Special offer with this disc you have an option to buy a copy of the 3rd edition of the booklet, published January 1999.
- 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.
!Stellate
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.
A demo version may be downloaded from here (size 600K).

In preparation
More polyhedra data files for use with !PolyDraw or !PolyNet; let us know what you want.PRICES
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.
