Polyhedra Products

Software for polyhedra exploration and display

All our programs run on any computer running RISCOS 3 4 or 5 including StrongARM, Iyonix and ARMX6.
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. Details from the website http://www.virtualacorn.co.uk.

This page has details of polyhedra software for RISCOS, click here for other software.

Polyhedron plotting programs

!PolyDraw


Wire Plot	Red/Green stereo	Single colour shaded	Colour by no. of sides of polygon face

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.

and shaded images with shadows like this made later.

A demo version may be downloaded from here (size 397K)
PolyDraw is no longer marketed. 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.
Click here to see some !Polynet examples.
The latest version may be downloaded from here (size 199K)

!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.
The program may be downloaded from here (size 458K)

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;
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 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, click here, to download the 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)

!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.
The program may be downloaded from here (size 614K).
