There's nothing in the distribution, but here (in a following message) is a shell script geomview module that sets up stereo mode. If you run it manually it prints the following usage message: Usage: stereo [-crosseyed] [-hardware] [-toggle] [field-of-view(degrees)] This geomview external module selects a stereo view, using a pair of windows for either a crosseyed view or one suitable for Tektronix hardware stereo. Stereo setup is done once each time the module is invoked; if you move a camera (e.g. in fly mode) or reshape a window, you'll need to re-invoke it. A message appears giving the nominal viewing distance; this depends on the window size and angular field of view. If the field of view is too large (values > ~15 degrees are unpleasant), this module adjusts the field of view to something reasonable & moves the camera back to roughly preserve the scene. Options: -crosseyed Make window for crosseyed viewing, to the right of the current one (default) -hardware Make a pair of vertically stacked windows, for Tektronix mode -toggle Enable stereo if it was off, otherwise revert to normal FOV field of view in degrees; default is 12. Typical usage: put, say, (emodule-define "Stereo" "stereo -toggle 7") in your .geomview file; then click on "Stereo" in the main panel to invoke. Or, run geomview -run stereo 7 -- ... other geomview parameters ... The script is in /u/slevy/stereo at the moment. At some point I'll add support for this to geomview itself; until then, the two eyes' views won't be updated synchronously, and you have to re-invoke the "stereo" module when you move a camera or window (though not when you merely move objects). I'll send the script in a separate mail message to you, George. > 2.

Yes, it's "email@example.com", which all the geomview developers read. Stuart
