  The Geometry Center proudly presents a gallery of five new
interactive World Wide Web applications, designed for visualizing
and experimenting with geometric ideas in 2, 3, and even higher
dimensions.

These applications demonstrate the innovative use of fill-out forms
to maximize interactivity with virtual objects. We find this
technology exciting because it allows the distribution of powerful
visualization tools to a much wider audience of remote users.

So, if you're looking for something exciting and new to explore,
just web right over to the following URL and check us out!

Here is a quick overview of the contents of the exhibit:

QuasiTiler: by Eugenio Durand

  Try your hand at creating beautiful nonperiodic tilings of the plane,
  including the famous Penrose tilings.  QuasiTiler also helps you
  visualize the multidimensional lattices used to generate these tilings.

Cyberview: by Paul Burchard

  An interactive 3D object viewer for the World Wide Web. You can pick
  an object out of our predefined library, or learn about the OOGL
  format and define your own objects.

Lafite: by Adam Deaton

  Learn about the symmetry groups of the hyperbolic plane through
  Escher-like patterns, which are created by replicating a motif
  according to the symmetry group you choose.

Teichmuller Navigator: by Deva van der Werf

  Explore the space of all different angle geometries on a surface
  of genus two.  You can navigate through the space by moving
  vertices of a tiling of the hyperbolic plane by octagons.

Unifweb: by Carlos O'Ryan

  Discover and visualize Riemann surfaces having a specified group of
  symmetries.  Different families of surfaces can be constructed for
  the same symmetry group by choosing different generators and relations.

If you have any questions about this interactive exhibit, please send mail
to webmaster@geom.umn.edu, burchard@geom.umn.edu or daeron@geom.umn.edu.
