!WimpPoly a demonstration of the use of the Desktop from Fortran
using the "Fortran Friends" PD_F77 library.
Version 2.00 2 February 1992
WimpPoly plots two views of a polyhedron, a 3D solid and a planar net, from
over 140 possible data files mostly downloaded from 'netlib' on the Joint
Academic network. It uses the 16 colours natural to the Wimp, so should be
run in 16 colour modes. Examples of window creation are in routine INIT,
some using Templates, others calling create window routines directly.

Essential Textfiles read by WimpPoly while executing
PolyHelp Running instructions seen in the 'Help' window in response to
clicking the 'menu' button over the 'choice' window with the
lists of polyhedron names. If you change this file to make it
more meaningful, remember that only 25 lines are displayed.
PolyList The list of polyhedron names stored in the datafiles, Dat1,
Dat2, Dat3. Lines beginning with a blank space are section
titles, plotted in red on the polyhedron choice window.
Positive numbers at the beginning of a line are the polyhedron
index number used to find the datafile for the polyhedron of
that name. The name makes an icon in the choice window which
you 'select' with the mouse button to see the polyhedron.
Negative numbers are alternative names shown in green.
There are 3 'test' files at the end to let you add more
datafiles without changing PolyList. The current maximum
number of lines allowed in PolyList is 160
Textfiles for your Information
DataFormat defines the datafile format so that you can add your own.

DrawFiles
IcosaNet a planar net of the Icosahedron, with 'tabs' drawn on manually
using 'Draw' to show you how to construct a solid model.
There are also a variable number of other Drawfiles depending on how much
space there is on the disc. They are composite files showing selections of
Polyhedra, made using 'Draw' to combine the files of single polyhedra
'saved' from !WimpPoly. Their names should explain what they are, e.g.
'Platonic' shows all the Platonic solids, 'ArchiDual', the Archimedean
duals, 'Prisms', shows prisms and anti-prisms.
Notes.
1. Known Errors in datafiles.
The algorithm used to plot the polyhedra assumes they are made from
non-intersecting plane faces. This is not true for some of the 'netlib' data
which plot incorrectly. Files with known errors are:
No. problem
8 has same net as 4
32 no 3d vertices only the planar net
66-69 3D connectivity of some vertices missing from central region
If you can correct these, or make new datafiles, please send them to the
library organiser, address above, so that others can share them.
2. Making Models and Useful books
You can make your own models by plotting the 'Drawfiles' saved from
the 'net' window, sticking them on card, and cutting them out leaving
flaps to stick the sides together as shown in the example 'IcosaNet'.
We find it easier to bend along the dotted lines of this icosahedron
before cutting anything out. Please tell us if you find a good way to
glue in the last piece!
You can learn more about making models of polyhedra and their
stellations from the following paperback books:
