Quick HowTo on configuring WWT for a multi-machine cylindrical display (aka Liquid Galaxy) RRS feed

  • Question

  • Hi, Below is a link to a short HowTo I did for setting up Microsoft Worldwide Telescope on a small multi-machine cylindrical/panoramic rig - basically a set of PC with the screens arranged on a curve. This is the same physical setup that we use for a Google Liquid Galaxy rig. http://code.google.com/p/liquid-galaxy/wiki/WWT Hopefully this will help anyone else trying to do something similar. If you have any questions/feedback/etc let me know. Cheers, Andrew eResearch / University of Western Sydney

  • The name is used for multi-channel full dome calibration. This name will be used to identify the monitors in the calibration screen on the WWT master, and for display on each display/projector during the calibration mode.

    PS. The images look great in your link. Most people don't know that the first public display of WWT was in 2007 on a 27 monitor display wall. WWT has been multi-channel enabled since well over a year before we released a public version!

  • Once you have the displays set as projector serers (master = "false"), you can change the heading pitch and roll to sen the relative projections of each of the monitors in the cluster.

     

    This differs from the tiled display wall. In a tiled display wall the monitor count > 1, but in a dome or cylidrical projection, each of the counts for x & y are 1, and the x and y= 0 while the heading, pitch, roll, field of view, etc are set to create set of displays that look good from the users eye point AKA the sweet spot.

  • Hi Jonathan, yes this is exactly what I did.

    BTW their is a typo in the config.xml that WWT self-generates. "NodeDiplayName" I assume this should be "NodeDisplayName". I just left this settings blank, what is it used for?
