Dear Members,
Is any one using NVidia NVision 3D Setup with active stereo in linux distribution for crystallographic work? Which one would be the best choice to set up, an active stereo or a passive stereo for crystallographic work? Can anyone shade some details on this? I am planning to buy or build a new workstation with stereo set up. It would be great if someone can give some estimate on this.
Many thanks,
Hena

Hi,
Yes
Active has better quality, greater 3D viewing area for people not
sitting right in front of the monitor, but is more expensive if you
have to purchase additional goggles ($70 non-nvidia online retailers -
$120 currently from nvidia)
Going with the lowest prices:
$300 Quadro 3700 :
http://www.google.com/products/catalog?q=quadro+3700&cid=5758926893192813358&ei=i8FwTpqJGpGkwgXtw9H4CQ&ved=0CAkQgggwAA#scoring=tp

$150 3D Vision kit with the 3 pin mini din "VESA" to 2.5mm stereo
cable : http://www.nvidia.com/object/product_geforce_3D_VisionKit_us.html
Total = $770
Passive stereo :
$490 (open box) - $550 : Zalman ZM-M240W :
http://www.compuvest.com/Search.jsp?Search=ZM-M240W&advsite=froogle&sku=756009288-08&dp=3:CVS:51392:0:21
You can use the black RealD 3D movie theater goggles with the Zalman
if you need extras. People also sell these online for a $1 + shipping.

I run the Alienware OptX AW2310 on two of our 3D Linux workstations and it looks spectacular. Make sure that you have a Quadro FX Nvidia video card that is on the approved list (http://www.nvidia.com/object/quadro_pro_graphics_boards_linux.html) with 3-pin stereo (3-pin stereo connector required for Linux, it will work without one in Windows through USB) output and not just a normal GeForce Nvidia card or you won't be able to run stereoscopic 3D in Linux.
One option that supports both Mac and Linux are the "Zalman" brand 3D monitors. Some people like them, some people don't. Unless Zalman significantly improved the technology on their monitors (ie: the right eye can see odd numbered rows of pixels and the left eye can see even numbered rows of pixels) you lose a significant amount of resolution from displaying 3D on these. Due to half the pixels being drawn to each eye, the display on the 3D Vision system using a 120 Hz monitor will look crisper and higher quality than the equivalent Zalman monitor when displaying stereoscopic 3D. That being said, this solution is significantly cheaper than the Nvidia system.
I've used and seen both and prefer the quality of the Nvidia 3D Vision, but some people are happy with the Zalman setup. It's really up to personal preference as to which you will choose.

We haven't tried any, but here's an interesting 120 HZ LED monitor
(Acer HS244HQ):
http://www.newegg.com/Product/Product.aspx?Item=N82E16824009301&nm_mc=OTC-Froogle&cm_mmc=OTC-Froogle-_-Monitors+-+LCD+Flat+Panel-_-Acer+America-_-24009301
It comes with active 3D goggles, but it's noted that these only work
with the 3D sync signal built into Bluray movies which I think is
transmitted off the monitor. Now if this works like 3D DLP link stereo
then you don't necessarily need the 3D vision stereo kit/emitter at
all. In fact, we have an Infocus IN3116 projector that does 120Hz at
720p and a bunch of $50 DLP link goggles, a quadro 3700 video card in
the box, and can do stereo in Windows 7 and Linux using Option
"Stereo" "3" (standard quad buffered stereo). We use a cheap $2 DVI to
HDMI converter to connect a long HDMI cable into the projector from
the Quadro 3700 and that's it, no super long 3 pin mini din cable is
needed. The only downside is that sometimes the left and right eye
images are on the wrong sides when stereo is enabled, but most apps
(e.g. pymol, chimera, and coot too probably) have an option to swap
the eyes when in stereo so that's easily fixed.

A better card won't improve the stereo quality itself, but will
improve surface, vdw, etc renderings with high polygon counts. For
building models, most people are looking at wireframes/lines which you
can still do for huge macromolecules on an SGI Octane. So yes, the
5600 will work with nvidia 3d vision, it has at least a G8x core
(http://en.wikipedia.org/wiki/Nvidia_Quadro) and the stereo connector
in the back. If you decide to go with something like that Acer HS244HQ
it would be interesting to see if it can be made to work without the
nvidia 3d vision kit at all.

Hi,What is being marketed as "LED" monitors recently are actually LCD monitors which use LEDs rather than fluorescent lamps for backlighting. So long as your monitor is compatible with the stereo technology you are using, LED backlighting is fine (and more efficient).

It's edge LED backlit. I don't know if there are any direct LED
backlit 120Hz monitors. Couldn't find much information on those types.

I highly doubt this monitor will work in Linux unless you buy the 3d
vision kit which comes with the emitter that you can hook into the 3
pin mini din port of your quadro (btw your quadro 3800 requires an
extra 3 pin mini din bracket, more on that below).
This monitor has a built in emitter that works with the pair of nvidia
(these are not generic active shutter goggles) 3d vision goggles it
comes bundled with :
http://3dvision-blog.com/review-of-the-27-acer-hn274h-3d-vision-ready-lcd-monitor/
...but does not have an input for the 3 pin mini din coming off a
proper quadro. The latest nvidia driver for linux still mentions that
you need the 3 pin mini din for nvidia 3d vision stereo in linux:
http://us.download.nvidia.com/XFree86/Linux-x86_64/280.13/README/xconfigoptions.html
####
Option "Stereo" "integer"
10 NVIDIA 3D Vision mode for use with NVIDIA 3D Vision glasses.
The NVIDIA 3D Vision infrared emitter must be connected to a USB port
of your computer, and to the 3-pin DIN connector of a Quadro graphics
board (based on G8xGL or higher GPU) before starting the X server.
Hot-plugging the USB infrared stereo emitter is not yet supported.
Also, 3D Vision Stereo Linux support requires a Linux kernel built
with USB device filesystem (usbfs) and USB 2.0 support. Not presently
supported on FreeBSD or Solaris.
####
Having just the USB connected to the emitter still only works in
windows with the standard emitter. I also know that the windows nvidia
driver explicitly checks to see what sort of monitor you have before
enabling 3d vision (see the nvidia 3d vision wizard in the nvidia
control panel), i.e. that's probably why you don't need a USB cable
connected from your computer to this particular monitor where the
emitter is housed in the bezel.
So, basically if you decide to go with this monitor you'll still
probably need to get the 3D vision kit with the proper emitter and
you'll also need to get the 3 pin mini din bracket for your Quadro
3800 since it doesn't have the 3 pin mini din output:
There's a forum about it here :

Either would be fine.

i'd say the i7 2600 @ 3.4GHz, uses less power too.

Buy the 2nd one, get a quadro 3700, get the 3d vision kit, and if you
want a 120Hz 27" "LED" monitor, here's one :
http://www.buy.com/prod/samsung-syncmaster-s27a750d-27-3d-led-lcd-monitor-16-9-2-ms-adjustable/223430191.html
that doesn't have a built in emitter which as mentioned above probably
isn't going to work in linux.
