Thanks to the work of
Scott Vorthmann this website is fully functional for the first time in
years.
The 3-D images are generated using VRML.
Browser support for this technology disappeared in the early 2000s.
Thanks to the X_ITE
team and Scott's coding, this and other VRML based
sites can now be enjoyed once more as intended.
Scott's VRML Revival project page can be found at vorth.github.io/vrml-revival/
If you have local VRML files, they can be viewed using Sunrize.

Near Misses: Polyhedra that are not quite regular, including near-misses to the Johnson Solids (the 'A-list') and acrohedral near misses amongst others.
This site is designed primarily to provide some form of ordered access to the many VRML models of polyhedra I have made over the past few years, mainly using my programme "HEDRON" (which I have made available). HEDRON was used to generate most of the models shown on this site.Jim McNeill
