IMAGE DESCRIPTION:

The Klein bottle is a fundamental surface in topology, and is quite 
beautiful in its own right. This form of the Klein bottle is not well known. 
     
DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

To obtain this image of the Klein bottle, I used the parametric description given by C. Henry Edwards in his Mathematica notebook "Twisted Tubes.ma". After Mathematica computed the necessary graphics primitives the file was converted to DXF format using an efficient converter written by John Novak. This was then converted to a pov file using the converter dxf2pov. Alternatively, one could use the package written by Roman Maeder in his book on Mathematica Programming. PovRay users should consult his chapter on Ray Tracing. The geometry file is about a megabyte, and is not included. Interested parties should send me e-mail at this address: matmjg@cs.gsu.edu
