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.

Polyhedron plotting programs
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.

PolyDraw is no longer marketed. 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.
The program may be downloaded from here
(You will need a copy of the applications !PolyDraw or !PolyNet to use these)

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

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,

The resulting polyhedra may be
saved in several formats, for later use in !Draw, !Stellate, !PolyDraw or
