[Chimera-users] Stereo on Mac OS X, 10.4

Almost a year ago, I asked if there were plans to support stereo on  
Mac OS X.  Greg replied that Chimera could only when Mac OS X  
supported stereo-in-a-window (see my question and Greg Couch's answer  
below).  There seems to have been some progress on this by Apple.   
Their "scientific visualization" page (http://www.apple.com/science/ 
researchsolutions/visualization.html) says:

Thanks to its PCI Express architecture, the Power Mac G5 with the  
optional NVIDIA Quadro FX 4500 graphics card gives researchers 3D  
stereo-in-a-window capabilities using a CRT display and  
Stereographics CrystalEyes liquid crystal shutter eyewear and E2Mac

If I buy the NVIDIA Quadro FX 4500 graphics card, will I now be able  
to run Chimera in stereo on a Mac?

Only if Mac OS X supports stereo-in-a-window.  That appears to be
unlikely because stereo-in-a-window is a feature that is only  
supported on
workstation-class graphics cards (NVidia Quadro, ATI FireGL, 3DLabs
Wildcat), and Apple only sells consumer-class graphics cards (NVidia
GeForce, ATI Radeon).

chimera needs stereo-in-a-window, instead of full-screen stereo, so the
scientist can still use the dialogs to control chimera.  If we figure  
a reasonable way to keep the (mono) dialogs working in full-screen  
then we will support stereo on the Mac.  (This also presupposes that  
of the Tcl/Tk on Aqua bugs are fixed.)
