RE: [PyMOL] Nuvision stereo glasses?

Yes! Real quad-buffered stereo is IMHO crucial for molecular modelling =

I doesn't work for me :-(   I ordered a Quadro4 750XGL, and the vendor =
sent
me a Quadro FX1000 by mistake. I didn't notice at first, and just =
installed
the card. Works fine and very fast with the 1.0-4363 version of the =
Linux
driver - but neither PyMOL or VMD detects any hardware stereo.... I =
have to
get it replaced by a 750XGL or 900XGL.

We have some older stereographics glasses, which I expect will work =
with the
Nvidia cards. But we have also bought a set of Eye3D premium glasses. =
They
come with a VGA pass-through cable, which can catch the sync signal =
from any
VGA output. They also support different stereo modes, including =
interlacing,
page-flipping, sync-doubling, and line-blanking. You get two sets of =
glasses
(one wired, one IR) for =88179 or $199. This works nice with PyMOL and =
the Xig
X-server on an ATI Radeon 9000 card, and the "Scanline interleave"
(interlaced) stereo mode in VMD works fine with these glasses and any
graphics adapter. Maybe "scanline interleave" could be a stereo option =
in
PyMOL - it is definitely inferior to quad-buffered stereo, but it works =
with
_any_ graphics card and doesn't require a special driver. (I would =
still go
for QBS, though :-)
