That makes sense. On Windows, Chimera is a wrapper around CHIMERA/bin/pythonw.exe (or CHIMERA/bin/python.exe if debugging). Thank you for following up on this, Greg On 06/29/2011 12:36 PM, William Joseph Allen wrote:
Hi Greg,
I was finally able to figure out what I was doing wrong. On the Nvidia control panel, I was changing the following settings:
Stereo - Enable: 'On' Stereo - Display mode: 'Generic active stereo (with NVIDIA 3D vision)'
For only specific programs (VMD, MOE, Chimera). That worked for VMD and MOE, but not for Chimera. As soon as I made those settings global, I was able to use stereo in Chimera. There must be other programs, like python.exe or something, that must also be stereo-enabled for this setup to work.
Thanks again for your help,
William Allen

So according to the wglinfo output, your driver is not configured for stereo. Check out the st/ro column, it is always a '.' and there should be some 'y's. So no OpenGL stereo program should work. I did try the 275.36 driver with our Quadro FX 3700, and stereo did work, so it is unclear why stereo isn't working for you. To confirm that the driver configuration is working, try one of the passive stereo options for the "Stereo - Display mode" and rerun wglinfo (or Chimera) to see if stereo is supported. You also might want to go over the driver settings with a colleague to see if either of you can spot anything, and if that doesn't work, try an earlier version of the driver.
Good luck,
Greg

I'll summarize what I find to chimera-users.

Hi Greg,
Thank you very much for your quick reply.
I had actually already changed those settings in the Nvidia control panel. They are as follows:
Stereo - Enable: 'On' Stereo - Display mode: 'Generic active stereo (with NVIDIA 3D vision)'
The display mode you mentioned in your reply was not an option in my Nvidia control panel. Although, this is the only setting that really makes sense for what I am doing, and I tried most of the other settings without success. I also tried toggling some of the other features in a non-random way, but without success.
These two settings, however, are the changes that made stereo in VMD and MOE start working (both of which use OpenGL). But, for whatever reason, Chimera still gives those previously mentioned errors when I try to turn on stereo. If it helps, the monitor is an Asus 120 Hz LCD display connected by a dual-link DVI cable directly to the graphics card. No DIN connector is involved.
Thanks again,
William Allen

It's should be a driver configuration issue. There are two different 3D graphics APIs on Windows, Direct3D and OpenGL, and most Windows applications use the former and Chimera uses the latter (because it works on Linux and Mac OS X too). To configure OpenGL stereo in the Quadro driver on Windows, bring up the NVIDIA Control Panel, navigate to 3D Settings, then Manage 3D Settings. And in those options, set "Stereo - Enable" to on, and "Stereo - Display mode" to the appropriate type of stereo, in your case, my guess would be "On-board DIN connector (with NVIDIA 3D Vision)".
HTH,
