RE: [PyMOL] Stereographics CrystalEyes problem

[Schubert, C. <Car...@3d...>]

Hi Viktor,

just a wild guess, but in order to get stereo to work on my PC (under W2K)
with a Oxygen GVX card I had to use a "ENT" emitter from Stereographics. As
far as I recall the regular emitters used on the SGI's, type "ESGI", did not
work.

Hope it helps.

Cheers

	Carsten

Subject: [PyMOL] Stereographics CrystalEyes problem


Hello,

I followed the discussion on 3D stereo support in PyMOL and saw that 
many people were able to get PyMOL in stereo with FireGL or Nvidia 
cards. Finally I got the chance to try it out myself with a new NVIDIA 
Quadro4 XGL 900. I am running PyMOL on RedHat 7.3 wiht the latest nvidia 
drivers (1.0-3123). There were no problems to get accelerated X up with 
blazingly fast PyMOL rendering. So next, I tried to get stereo working. 
I am using Stereographics emitter and CrystalEyes which I've been using 
with our SGIs (so that I know they are functional; in fact PyMOL works 
in stereo on our SGIs without a problem). I plugged the emmiter into the 
DIN on my Quadro4 card, put   Option "Stereo" "3"   into my 
XF86Config-4, restarted X and hoped that things will just work. 
According to XFree log file, X was really initiated in stereo mode. The 
emmiter light turned on when I started PyMOL. I switched to 'quad 
buffered stereo' and the molecule getss rendered in stereo but when I 
look at it with CrystalEyes glasses nothing changes. I still see double 
rendered image on the screen, which means that the emmiter does not 
synchronize glasses correctly (or at all).
I tried to change some options in XF86Config-4 but nothing helped, so I 
was wondering if someone experienced the same problem. Do Stereographics 
emmiter and CrystalEyes glasses work with Quadro4 at all? Do I need to 
get a different emmiter or glasses? Any help appreciated...

Thanks,
-Viktor
