A quibble, chimera is not crashing, it's just refusing to run. So the likely reason that midas worked and chimera doesn't, is that chimera doesn't support split-screen stereo where you lose half of the screen's vertical resolution and midas does. You can confirm this by checking the output of the /usr/sbin/glxinfo program. The st/ro column will have a 'y' in it for the visuals that support good stereo. You can also give the -v option to glxinfo and grep for 'stereo=' -- in your case I would expect that they are all 'stereo=0'. If I am wrong, then there will be a few 'stereo=1' entries (and it would be a bug that chimera refuses to start up). Depending on the particular IRIX computer you have, you might be able to get the good stereo by lowering the default screen resolution and restarting the X server by logging out and back in (try 1024x768 first, or if you're using an O2, configure the framebuffer to 32+32 mode). If that doesn't work, your next solution would be to find an IRIX computer with better graphics or switch to a PC with a workstation-class graphics card with stereo support. See <http://www.cgl.ucsf.edu/chimera/1.2065/irix.html> for a few more details. Hope this helps, Greg Couch UCSF Computer Graphics Lab gregc@cgl.ucsf.edu On Mon, 24 Jan 2005, Liu, Hao-Yang wrote:
Dear Sir/Madam,
I am running chimera in IRIX, and when I am trying to run "chimera --stereo", I got this message:
Unable to find hardware stereo support (Togl: couldn't get visual)
and when I click ok, the program just quit.
I can use the normal (mono) mode in chimera. and I think I had the hardware, because I use midas a lot, and never had problem in midas.
Could you tell me how can I use the stereo mode in chimera? What am I missing?
Thanks Hao-Yang Liu
