I am now using an autostereoscopic display (no 3D glasses required) from DTI

essentially no eye strain and no flicker at all.  

It does not work correctly with COOT since it requires a slight modification to the side by 
side stereo mode to work correctly.  Essentially the left and right images are rendered 
full size, then compressed horizontally by half before being displayed. Is it possible to 
add this mode to COOT or provide info on how to do it so I can make a special version.  
Here is the exact info from the DTI Technologies website:


Do you get "fat" molecules (too wide) when you use side by side stereo 
in Coot then?


Use of DTI screens is unsupported until they send me one to play with :)

try compiling clipper with -fno-strict-aliasing, or drop the
optimization flags to -O1 or lower.


For fundamental solution is "use union type" in clipper.
See the section of -fstrict-aliasing in "man gcc".


The reason I haven't done this is that the one function for which this 
is an issue is performance critical, and it is not clear to me that the 
union implementation will optimize as well. It all comes down to how 
good the gcc optimiser is. I will try it when I get time.

Yes, when you use the side by side in COOT with the autostereoscopic display 
the molecules 
are too fat by a factor of 2.
