[Chimera-users] changing the rgb for stereo images

Hi Bala,

It is not possible for for chimera to set the RGB frequencies, those are 
determined by your display.  But there are several things that can be 
done to reduce and/or eliminate the ghosting you see:

      1. Don't use any saturated colors: you'll get the best effect with 
gray-scale images.

      2. Get better red-cyan glasses: In general, paper glasses are 
blurry compared to plastic glasses.  But some plastic glasses do a 
better job than others -- you'll need to do some research.

      3. Reduce the amount of parallax in the image -- have (most) 
everything behind the focal plane.  Reducing the eye separation might 
help too.

      4. Not likely, but you might need to turn off any color correction 
that your display is doing.  Chimera does not use any color management, 
so an image in just the red channel should only be shown with the 
display's red light, but is possible that your display or operating 
system is remapping the colors to match a particular ICC color profile, 
e.g., the sRGB profile, and that might cause ghosting.  The effect 
should be too small to notice though.



P.S.  Researching this I came across magenta-green stereo which is 
supposed to be better than red-cyan stereo.  Since you can buy 
magenta-green glasses, I will add support into the daily build. Note 
that magneta-green are right-left colors, unlike red-cyan which are 
left-right colors.
