On the subject of nVidia graphics cards, linux and stereo, I feel I ought to 
mention the Asus VG278H.

This is a 120Hz 27 1920x1080 monitor with a built-in nVidia 3D vision emitter, 
which comes bundled with a pair of 3D vision glasses.  The great thing about 
the built-in emitter is that it takes stereo synch from the DVI cable even 
under Linux.  This removes the need for a Quadro card with a 3-pin mini-DIN 
connector or 3-pin adapter.  Here in the UK our cheapest supplier was selling 
it for £380 ex. VAT.

There is little information about using it with Linux on the web, but as I 
understand it you still need a Quadro card. I got it running with little 
trouble using a Quadro 2000, Ubuntu 12.04 LTS and the latest nVidia drivers.  
It may be possible to use cheaper Quadro cards.  The picture and stereo quality 
is excellent when compared to our existing stereo systems.

[ccp4bb] GeForce Graphics cards

2013-02-13 Thread Alex Kavian
Hi there,

I have an off-toptic question about Graphics card. My searches on pymolwiki and 
ccp4bb archives resulted in the following conclusion: Coot and pymol are not 
compatible with the new GeForce graphics cards. Hoewver, most of the posts I 
found were from 2009 and 2010. Does anyone here have any experience with 
GeForce 660 or 680 for stereo applications of Coot, Pymol or UCSF chimera? Will 
quadro cards work equally smooth in the stereo mode of these programs? Do 3D 
applications put too much pressure on the Graphics card which would justify 
installing dual Graphics card? (not sure if is relevant, but just for the 
record, we want to buy passive 3D monitor due to the budget restrictions).

Thanks,
Alex

Dear Alex,


  I'm not sure why you think the new Geforce cards will be an issue.  Please 
clarify.

As far as stereo is concerned, Geforce cards only give stereo under Windows, 
not Linux.  If you want stereo under Linux you need the Quadro cards with the 
stereo option (for example, Quadro 4000 or 5000).  Not all Quadro cards support 
this option, and so would only give stereo under Windows, like the Geforce 
cards.

Not sure about the passive type of stereo;  I have a feeling that will also 
only work under Windows.  I'm also not sure it works with Pymol and Coot.  
Perhaps someone can clarify this.

As far as I know the stereo under Linux is only the active variety, using the 
NVidia 3D Vision glasses.

Harry,

I found this on pymol wiki NVidia 3D NVision kit only supports DirectX
software for GeForce (gaming cards) on Windows; users are reporting that
they are not able to run PyMOL with NVision with these cards. Get a newer
model low end quadro ( G8x graphics core) without the 3 pin mini din (e.g.
Quadro 370) or with the 3 pin mini din (e.g. Quadro 3700) for Windows. and
this too  The GeForce cards do not support windowed openGL stereo, so we
do not support these series of cards for the NVision 3D solution. For
linux, you must have a quadro card that has a 3 pin mini din connector. The
cheapest/oldest card that will work with linux is the Quadro 3700.* WARNING*:
The Quadro FX1400 does not support 3d vision stereo on Windows7 or Linux.
  This was posted there a while ago and I was wondering if there has been
any update to that which has not been posted.

Regarding the passive monitors, I think they are compatible with linux,
after all we have been using zalman for long time, which is technically a
passive 3D monitor. I also found posts on the ccp4bb from people happily
using LG D2342P monitor, though linux or windows was not mentioned.

Hi Alex,

Thanks for asking before buying. You've avoided a common mistake.

If you want to do 120 Hz stereoscopic 3D you must have a Quadro card.
GeForce cards, even the really expensive ones, are made for games (and
DirectX) not science. I've seen people pay upwards of $1000 for a
top-of-the-line GeForce card only to be disappointed to find out it won't
do in-window and full-screen OpenGL stereoscopic 3D like a $99 Quadro card
will.

If you're using passive 3D, like anaglyph or Zalman, then a GeForce card
should be capable. I've run both off a MacBook Pro before just fine.

Last, here's http://www.pymolwiki.org/index.php/Stereo_3D_Display_Optionsthe

Hi,

They might be, but please be aware that nearly all scientific applications
use OpenGL for drawing and 3D. Many games use DirectX, an MS standard, for
that. The capabilities differ by standard (OpenGL vs DirectX), hardware

Hi,

Since it is mentioned, I would like to take this chance to clarify:

We have used the Zalman and LG 2342P under Linux, Windows(XP and 7) and a VM 
Windows within a Linux system, on either desktop (with a minimal on-board 
graphic chip) or laptops. The monitor is quite plug-and-play in all cases we 
have tested. According to the internet, these monitors also work with Macs for 
stereo game play and stereo video viewing. 

In regard to the crystallographic software, the Zalman mode is supported by 
COOT, Chimera, and the new Pymol (but not the 0.99) - we have tested them all 
in both Linux and Windows. 

Passive 3D only requires the graphic program to send out the left and right 
images in alternating lines. To my understanding this suggests that it is 
independent of OS or graphic cards. But for Mac users, I think the first thing 
to check is whether the Mac COOT and Chimera has a Zalman mode option. 

Here's the link to my previous reply on the BB regarding our experience with 
the Zalman and LG D2342:

Re: [ccp4bb] GeForce Graphics cards

2013-02-13 Thread Zhijie Li

Hi Alex,

The graphical computational power of even the lowest-end graphic chips these 
days will suffice the displaying of our models. To give you some idea: we 
are still using a Quadro FX 1000 card and an old CRT on one of our stereo 
systems; my 6-year old laptop has an ATI Radeon X1300, which can still drive 
the stereo display on Zalman or LG D2342P. You can check the benchmarks of 
these chips to see why dual card is guaranteed to be a waste.


If you are determined to go the passive 3D monitor(Zalman or LG D2342) path, 
then you actually do not need to worry about the graphic card - even the 
on-board one will do. Quadro cards are for the use with 120Hz monitors and 
shutter glasses, whereas the passive 3D monitors are CPL-based and do not 
need special graphic cards.


Having said all the above, UCSF Chimera might become a little demanding when 
displaying electron densities, so a discrete mainstream Nvidia or ATI chip 
would probably make life easier in a few cases.

 and pymol are not compatible with the new GeForce graphics cards. Hoewver,
 most of the posts I found were from 2009 and 2010. Does anyone here have
 any experience with GeForce 660 or 680 for stereo applications of Coot,
 Pymol or UCSF chimera? Will quadro cards work equally smooth in the stereo
 mode of these programs? Do 3D applications put too much pressure on the
 Graphics card which would justify installing dual Graphics card? (not sure
 if is relevant, but just for the record, we want to buy passive 3D monitor
 due to the budget restrictions).

 Thanks,
 Alex

Hi Alex,

We actually didn't invest on a discrete video card for the LG-D2342P system. 
The one we are using on the LG-D2342P desktop is the integrated Intel HD 
graphic 2000 chip, which is physically located in the CPU. The CPU is i7-2600. 
We installed a Linux OS on this desktop and also run a VirtualBoxed Windows XP 
inside the Linux for office jobs. Due to some limitations of the Virtualbox, 
the VM Windows system does not get hardware 3D acceleration, but still the 
speed of rendering is fine in most cases even for UCSF Chimera. In Linux there 
is no issue on speed.

Hi Zhijie,

thanks for the link. I was actually referring to that post. Can you please tell 
me what graphics card you are using?

Alex

  Hi,

  Since it is mentioned, I would like to take this chance to clarify:

  We have used the Zalman and LG 2342P under Linux, Windows(XP and 7) and a VM 
Windows within a Linux system, on either desktop (with a minimal on-board 
graphic chip) or laptops. The monitor is quite plug-and-play in all cases we 
have tested. According to the internet, these monitors also work with Macs for 
stereo game play and stereo video viewing. 

  In regard to the crystallographic software, the Zalman mode is supported by 
COOT, Chimera, and the new Pymol (but not the 0.99) - we have tested them all 
in both Linux and Windows. 

  Passive 3D only requires the graphic program to send out the left and right 
images in alternating lines. To my understanding this suggests that it is 
independent of OS or graphic cards. But f
  or Mac users, I think the first thing to check is whether the Mac COOT and 
Chimera has a Zalman mode option. 

  Here's the link to my previous reply on the BB regarding our experience with 
the Zalman and LG D2342:

  Harry, 

  I found this on pymol wiki NVidia 3D NVision kit only supports DirectX 
software for GeForce (gaming cards) on Windows; users are reporting that they 
are not able to run PyMOL with NVision with these cards. Get a newer model low 
end quadro ( G8x graphics core) without the 3 pin mini din (e.g. Quadro 370) 
or with the 3 pin mini din (e.g. Quadro 3700) for Windows. and this too  The 
GeForce cards do not support windowed openGL stereo, so we do not support these 
series of cards for the NVision 3D solution. For linux, you must have a quadro 
card that has a 3 pin mini din connector. The cheapest/oldest card that will 
work with linux is the Quadro 3700. WARNING: The Quadro FX1400 does not support 
3d vision stereo on Windows7 or Linux.   This was posted there a while ago and 
I was wondering if there has been any update to that which has not been posted.

  Regarding the passive monitors, I think they are compatible with linux, after 
all we have been using zalman for long time, which is technically a passive 3D 
monitor. I also found posts on the ccp4bb from people happily using LG D2342P 
monitor, though linux or windows was not mentioned.

Dear Alex,


  I'm not sure why you think the new Geforce cards will be an issue.  
Please clarify.

As far as stereo is concerned, Geforce cards only give stereo under 
Windows, not Linux.  If you want stereo under Linux you need the Quadro cards 
with the stereo option (for example, Quadro 4000 or 5000).  Not all Quadro 
cards support this option, and so would only give stereo under Windows, like 
the Geforce cards.

Not sure about the passive type of stereo;  I have a feeling that will also 
only work under Windows.  I'm also not sure it works with Pymol and Coot.  
Perhaps someone can clarify this.

As far as I know the stereo under Linux is only the active variety, using 
the NVidia 3D Vision glasses.

Harry
