Hi all, I have a question. My department just got a GeoWall, which is a set of
2 digital projectors that allows users to view images in 3d using polarized
glasses. I was curious if there has ever been any talk of using NVIZ as a
stereo viewer. It would require two screens from NVIZ that could be viewed at
the same time in stereo. The only option right now is to make vrml files and
view them with other applications, or to use the new version of ArcScene (boo
expensive ESRI). Would this require mountains of work to implement? Any ideas
out there?
thanks, Ian

Implementing this on an SGI system which has the SGIStereo
stereoscopic X11/OpenGL extensions should be trivial. The Togl widget
(on which NVIZ is based) already includes support for this.
Implementing it on other systems would be less trivial; you would need
to create two Togl widgets, each with a slightly different projection.
Most of the effort involved would probably be in figuring out how NVIZ
works and which parts need modifications; the modifications themselves
probably wouldn't be particularly complex.
