ANNOUNCING: The Geometry Center's Interactive On-Line Gallery
Fri, 11 Feb 1994 09:52:59 --100

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

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.
