GeoWall

Q: What is a GeoWall?
A: It is effectively a standardized name for a dual projector passive stereo setup, see the Geowall Consortium site for more information. Make sure you check out the archive of the geowalltech mailing list.

Here are some flowcharts Stephanie Andrews made to show the process of developing exhibits for the Web (Technical, General) and for GeoWalls (Technical, General).

Walkabout

Q: What is Walkabout?
A: For our purposes, it is a browser for 3d models that works on GeoWalls. It is written by Andy Johnson at the University of Illinois at Chicago's Electronic Visualization Lab. Go to the Walkabout Page for more information and for downloads.

Q: How do I navigate in Walkabout?
A: Currently, this is keyboard only. Move with the arrow keys, press W and F to switch between Walk and Fly modes, E and C make you look up and down (i.e. craning your neck), G+right arrow during the Fly mode does a nice rotation around a point.

Wallview

Q: What is Wallview?
A: It is a slide show viewer for Geowalls written by Russ Burdick. For more information, go to the Wallview site.

Q: How do I navigate in Wallview?
A: After you click on the icon and two pictures appear side by side, left-click once on either of the pictures. After that, page down (or space) and page up move between pictures. The left and right mouse buttons permit translation and zooming. Wallview starts on a photo at the same place where the photo was stopped the last time it was viewed (if that makes no sense, you'll understand when it happens...)

Partiview

Q: What is Partiview?
A: Partiview is an open source 3d viewer written by Stuart Levy of the NCSA.

Q: How do I navigate in Partiview?
A: The key is to press a mouse button down, move the mouse, and release the mouse button. Navigation is inertia-based, so whatever you were doing when the mouse button is released continue to happens. If you want to stop movement, click once, without moving your mouse during the click.

  • Rotation : left click & hold.
  • Zooming: Right click (and hold!) the mouse and move up and down. (If you have a Mac with a one-button mouse, press the option key as you click that button.)
  • Stopping motion: click once with the mouse.
  • Translation. Press f. Left click-hold-move. When happy, stop the motion and press o. You're back in the 'orbit' mode that enables you to do 'everything' else except translation.

If you see buttons in your demo, click them to turn parts of the demo off and on.

Q: How do I right click on a Mac when my mouse only has one button?
A: Press CTRL while you press the mouse button.

Q: What else has Partiview been used for?
A: Check out the Digital Universe at Hayden Planetarium in NY, and how it's used for information visualization and machine learning by Dinoj Surendran.

Partiview for Developers

Partiview has two user guides, one from Hayden and one from Maryland. Developers should focus on the latter. Bear in mind though that Partiview has a lot more features than are actually documented.
