Gallery : Hyperbolic Escher

Thu, 15 Aug 2008 19:37:51 +0100

M.C. Escher only made four "Circle limit" drawings. These are tilings in hyperbolic geometry.
I now have a small gallery of 20 more of these: plain tilings in Euclidian geometry by M.C.Escher, transformed into the hyperbolic variety.

Dimensions

We finally, after 18 monts of work, were able to release "Dimensions", two hours of mathematical animation. 'We' means myself, Etienne Ghys and Aurélien Alvarez, both from the Ecole Normale Supérieure in Lyon.

Gallery : Sculptures

Tue, 04 Mar 2008 19:38:46 +0100

I have added a new gallery, the first in quite a long time.
This gallery is an experiment in using data generated in Ultrafractal as input to Povray. Calculations in Ultrafactal are exremely fast, but the raytracing possibilities are limited. Povray, on the other hand calculates very slowly, but has unlimited and fast raytracing. Combining the strong points of the two seemed the obvious thing to try out.
