Hi,

Not true...
I have hardware stereo, crystal eyes, in a window working with PyMol
on a non supported G5 1.6 GHz singel processor with an older video
card, not the new quadro

I am using a crystal eyes E2 emitter box plugged into the stereo
graphic stereo enabler cable that goes between the graphics card and
the monitor cable , which takes power from the keyboard port of an
adjacent SGI indigo 2, how ironic, into an old sgi monitor.

PyMol and OIRIX with the quad buff stereo plugin both work for stereo
in a window with the crystal eyes system.

Its not supposed to work but it does!

havent tried vmd yet

doenst work yet with bioimagexd which uses VTK , but we will get it
working as it doesnt work yet on linux either and it should

havent tried chimera either

Dan
