Hi, The following web page should answer your question: http://pymol.sourceforge.net/stereo3d.html On a related note, I recently came across a new 22" LCD stereo system which is below $1000 and requires polarized glasses ($10 each). It doesn't seem to be set up for OpenGL yet, so isn't suitable for Linux. I am curious as to whether anyone has it running on some DirectX molecular visualization software in Windows: http://www.iz3d.com/ Paul >From: Zach Powers <[log in to unmask]> >Reply-To: Zach Powers <[log in to unmask]> >To: [log in to unmask] >Subject: [ccp4bb] Flat Screen and Stereo >Date: Fri, 22 Jun 2007 16:38:21 +0100 > >Hello, > >I have been having a problem getting stereo to work on the lab's new >flatsceeen ( i know, i know.....
