Re: [ccp4bb] Zalman monitor on Linux and Coot

2009-11-04 Thread Justin Hall

Hi Ajit;

One of our CRT monitors broke recently, and in the context of  
bemoaning the loss to a friend I was told that LCD monitors will not  
work for stereo viewing. I understood the reason to be related to the  
difference in refresh rates (?), with LCD's not being fast enough so  
that the viewer is left seeing ghosts. The effect, which I have not  
seen first hand, was described to me as capable of making most hapless  
stereo viewers very ill, very fast. I would encourage you to plumb the  
depths of knowledge on this subject further, but that is my simple  
understanding.


Best wishes~

Hello everyone,
Sorry for a non-CCP4 related question again. Can anyone let me  
know how to make stereo work on linux with Zalman monitor with Coot?  
Is it as simple as what we do with CRT monitors? Or do we need  
something else? We presently use CRT monitors on a Quadro FX 4600  
graphics card. I would like to move to LCDs.


Thanks for all inputs

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.


My 5 cents,

Jürgen

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

2009-11-04 Thread Jim Fairman
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:

2.  Nvidia 3D Vision and QuadroFX Video Cards:

Re: [ccp4bb] Zalman monitor on Linux and Coot

2009-11-04 Thread Paul Emsley
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.
