Re: [ccp4bb] Zalman monitor on Linux and Coot
I should add that I have only seen Joel Bard's Zalman monitor briefly. We tweaked the settings a bit to improve the representation in the following way: 1) use nvidia-settings to override application anti-aliasing - crank it up to 16x if you have a good graphics card 2) add to ~/.coot file (or otherwise initialise coot with): (set-map-line-width 2) After that, it looked quite good (I thought). For the record, I do not think that Coot questions are off-topic on ccp4bb. Having said that, you might like to fine-tune your audience by posting to the Coot list (see the Coot Web page for details). Paul.

Re: [ccp4bb] Zalman monitor on Linux and Coot
I can personally verify that the new Nvidia 3D Vision system on 120 Hz LCD monitors and a Nvidia Quadro FX Video Card display stereo flawlessly in Pymol, Wincoot, UCSD Chimerica, and any other application that uses OpenGL or Direct3D as its display media within both Windows Vista and Windows 7 (Nvidia documentation says it will also work in Windows XP, but I have not tested this). This will not work in any Linux distributions yet (as far as I am aware), but here's to hoping they develop the drivers soon. Here are a few links: 1. Nvidia 3D Vision Webpage: http://www.nvidia.com/object/3D_Vision_Overview.html 2.

The Zalman defeats these with a very smart trick. We got out first one, and it's really very good, albeit not perfect in some details. Pymol and Coot worked just like that with it.

Re: [ccp4bb] Zalman monitor on Linux and Coot
Rubbish, excuse my English :-) I have four Zalman's running in stereo although I have to confess they're all running on various Macs (MacBook Pro, Mac Mini, MacPro) under 10.5 or 10.6. I have no clue if the Zalman runs under linux. Regarding the stereo effect it is superior than conventional CRT with shutter glasses.
