Hi Guys -
I got a Zalman 3D - it's pretty cool with Coot and Pymol. Your site says the row-interleaved stereo view under camera will work with this monitor, but I wasn't having much success. Do you have some more detailed instructions for this particular monitor?
I can drop by and visit with it, or you can come see me if you's like. Thanks! Miles in Yamamoto Lab S574 Genentech Hall
Do you have multisampling turned on? Multisampling on different graphics cards work differently. Some cards use values from adjacent rows for computing pixel values, and this really doesn't work when using row-interleaved stereo mode.
To check if multisampling is on, use the Tools->Viewing Control->Effects menu item to bring up the Viewing panel; the multisampling option should be the bottom-most one on the right.

Miles, The other obvious thing is that you need a newer version of Chimera than the 1.3 production release. Just grab any of the daily builds from www.cgl.ucsf.edu/chimera/download.html. If you still have problems after trying Conrad's suggestion come on down to GH-N456 and check the graphics settings we are using with our Zalman 3D display.

For stereo on the Mac I have been using the nvidia 4500 quadro card with a view sonic CRT, chimera with sequential stereo page flipped with an stereo graphics IR & glasses. In this scenario I was under the impression that the video page flip rate is 100-120Hz
The new 3D LCDs (e.g., Zalman, Hyundai) create stereo through circular polarization that require passive glasses. But these monitors are working at no greater than 75hz.
The bottom line question is: if I buy one of these units to replace my view sonic CRT, will it work on my Mac? I get the impression reading the technical specs that it might only work with vista and directX.
Thanks, Matt

The bottom line is that the stereo on the new 3D LCDs will work with chimera on newer and some older Macs (and almost all PCs).
Chimera has a special camera mode, "row interleaved stereo", that chimera uses to generate an interlaced image that the Zalman (Hyundai, Miracube, etc.) 3D LCD monitor displays in stereo, and the technique should work with any graphics card on OS X, Windows, or Linux. However, some older Macs have a buggy graphics driver that Apple hasn't fixed (maybe won't ever fix), so depending on what graphics card you have, it may or may not work. We are still in the process of figuring out what the exact bug is and might have a workaround for the 1.4 release.
To see if it will work without buying a 3D LCD monitor, display a model in chimera that has some depth, and switch the camera to "row interleaved stereo". Then on the left and right edges (where the left and right eye images diverge the most), you should see a feathering effect where alternating rows do not match up. IF you see the effect, your setup will work.
For completeness, if you have a workstation graphics card (ATI FireGL/FirePro, NVidia Quadro FX) on your Windows or Linux computer, then you can configure the graphics driver to do the row interleaving, and use chimera's "sequential stereo" camera mode. That will ensure that all of chimera's graphical features work, in particular, silhouette edges don't work in the "row interleaved stereo" camera mode.
