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.
I am not a professional mathematician, and as a consequence this site is as much a catalogue of models than a site providing any great mathematical insight. I have tried to be original in my modelling and I present here a large number of models that I have not seen elsewhere. Any VRML2 viewer should display the models. I recommend Parallel Graphics' Cortona, available here.
At times, I have modelled a polyhedron for which, to my knowledge, no formal name exists. In these cases I have tried to extend existing naming conventions. Where this is the case I have tried to make it clear. Any errors and omissions are mine.
