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:

and the 190-series 3D Vision driver for Windows Vista:

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!
