Hi Andrew,
active (or quad-buffered, sequential, hardware) stereo 3D is possible on
a MacPro, at least with a Nvidia Quadro card with a 3-pin Mini-DIN
socket, Stereographics/realD or NuVision shutter glasses and emitter,
and a suitable CRT monitor. But those are hard to find, nowadays (i.e.,
used monitors on eBay and alike).
I never heard whether this also works with a stereo TFT monitor and
Nvidia glasses and emitter. But a colleague of mine next door runs this
under Linux. So, I just plugged in the Nvidia emitter to the USB and
3-pin-Mini-DIN sockets on my MacPro, and connected a Samsung 3D
stereo-capable monitor. I could set the TFT monitor to 120 Hz, and
Chimera switches to sequential stereo, but, unfortunately, the Nvidia
emitter does not work together with the Mac (it blinks red instead of a
steady green light). Next test was to replace the Nvidia emitter with my
Stereographics emitter. This time, I do see something that reminds me of
stereo, but with heavy ghosting and blending of different depths through
the molecule - so, in short, it's not usable.
Hope, that helps.
Best regards,
Dirk.

Hi everyone,
The recent post about running coot on a powermac G5 has me a little
confused because I thought the only option for stereo on a Mac was to use a
Zalman monitor for passive stereo. I'm clearly missing something. Is it true
that active stereo with 120 Hz LCD monitors is not possible with a Mac? I'm
considering taking the plunge to switch over to Mac entirely, but one source of
hesitation is that I prefer active stereo and would like to move to LCDs if
possible.
Assuming I'm still correct that 120 Hz LCD active stereo is not
compatible with Macs, is it also true that this is unlikely to change in the
foreseeable future (i.e. Apple or Nvidia don't see enough financial benefit to
correct the problems ergo there is little driving force)?
Thank you for the enlightenment,
-Andy Torelli

Hi Juergen,
I have tried using fink before, but a precompiled binary would be easier...
I think Snow Leopard is incompatible with the G5 (and with ppc in general).
Leopard would work, I might try this if I can get an installation disk and
nobody has a binary compiled for 10.4 (Bill Scotts page does not have it
anymore for new versions of coot).
There are some rumours that Leopard broke the stereo, but also that the latest
updates fix it again.

Hi Mark,
have you ever tried using fink ? You don't need to do much to compile it
yourself with the help of fink.
Here's the link to fink (or better to Bill Scott's fink it yourself page)
http://sage.ucsc.edu/~wgscott/xtal/wiki/index.php/Getting_your_fink_installation_to_use_packages_that_I_have_pre-compiled
You will need Apple's Xcode, which you can get after registration for free.
Once you have installed fink you really only type fink install [name of program
you want], hit a couple of times y (yes) or whatever default value is requested.
You have to do the usual edits in your .bashrc or .cshrc file to point X11 to
your fink binary.
You also have the option to download precompiled binaries, but not sure if Bill
keeps still 10.4 - you might want to upgrade to Snow Leopard.

Dear All,
My second computer in the office is a Powermac G5 with MaxOSX 10.4 equipped
with a stereo-capable CRT and Nuvision emitter/glasses. I would like to install
coot on this, pref. prebuilt because I am hopeless at compiling...
The most recent build I could find is 0.5.2 ueno on Bill Scotts website -
anyone know of a more recent version compiled and compatible with our system.
would stereo work with a more recent version of coot?
greetings,
Mark
