Types of Downloads offered here

1. Interactive 3d Models These are distributed in zip files that include binaries of the open source 3d viewer Partiview, by Stuart Levy of the NCSA. Unzip each zip file into a new folder, then look for batch files to click on / run. These are .bat files for Windows, .command files for OS X and .csh files for Linux. Windows and Linux also have GeoWall versions. Generally, these models can only be run on recent computers with good graphics cards.

   Instructions for how to navigate Partiview models can be found here.

2. Movies. These are usually MPEG files that can be played with Windows Media Player or Quicktime.

3. Stereo Photos. These come with a GWD file that you can use with Wallview on a Geowall.

4. Walkabout Models : If you have a GeoWall, download and install Walkabout from the Electronic Visualization Lab at the University of Illinois at Chicago, and then open the WBT file in the folder with it. Navigating in Walkabout with a keyboard is easy; use the arrow keys to move your body, E and C to move your head.
