Continuing coverage...
Although GeForce 3D Vision is not officially supported for Windows XP, I
managed to get it to work with PyMOL. Assuming you have the following
setup:
- A 120 Hz LCD: a Samsung 2233RZ or a ViewSonic Fuhzion vx2265wm
- A recent Quadro series graphics card such as an FX 380 or 570.
- A GeForce 3D Vision hardware kit (an emitter with 3D shutter glasses).
- Windows XP 32 bit
You need the 190-series graphics driver for Windows XP:
http://www.nvidia.com/object/winxp_190.38_beta.html
and the 190-series 3D Vision driver for Windows Vista:
http://www.nvidia.com/object/geforce_3D_vision_winvista_win7_190.38.html
Instructions:
1. Uninstall the existing display drivers, disconnect the USB emitter,
and reboot.
2. Run the Window XP graphics driver installer and reboot.
3. Launch the Vista 3D Vision driver in order to extract the files you
need, but do not yet click Next on the Welcome page...just leave it open
for now...do not close the installer.
4. Plug in the USB emitter. Windows should throw up the Found New
Hardware Wizard**. Choose "No, not this time" and go to the Next page.
Select "install from a list or specific location" and click Next to
continue. Choose "Search for the best driver", "include this specific
location...", and click Browse. Now comes the hard part: you must
select the folder which contains the file "nvstusb.inf". On my system,
that file was unpacked into c:\Documents and
Settings\Warren~1~000\Locals~1\Temp\pft16~tmp - your copy may be in a
similar location. You may need to use Windows Search to find the file.
Once you've chosen the correct folder, click Ok and then Next. You may
then be asked to locate "nvstusb.sys", which should be in the same
folder. Click Ok once you've found the file, and then Finish. This
should complete installation of the USB driver.
**If Windows doesn't throw up the Found New Hardware Wizard, use the
Device Manager to locate the device and then update the driver for the
device using the same process described above.
5. Now allow the 3D Vision Installer to continue. Since your on XP, not
Vista, it will complain and throw up one warning and one error message,
but it should still complete. Reboot when prompted. The rest of the
instructions are basically the same as for Vista:
6. Open the NVIDIA Control Panel, and increase the display refresh rate
to 120 Hz using the display resolution tab. Then go to the 3D Settings
tab and set the Stereo display mode to "Generic active stereo (with
NVIDIA IR Emitter)", click Apply, and then set Stereo - enable mode to
"on", click Apply, and then close the NVIDIA control panel.
7. Launch PyMOL 1.2r1 for Windows. You should get the message: "OpenGL
quad-buffer stereo 3D detected and enabled."
8. Now load a PDB file and issue "stereo on". The emitter should light
up and the glasses should activate.
Congratulations -- you should now be able to view PyMOL molecular
structures in stereo 3D on a 120 Hz LCD using Windows XP!
Cheers,
Warren
