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


You can try this:

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 :)

[COOT] autostereoscopic displays

I am now using an autostereoscopic display (no 3D glasses required) from DTI 
Technologies.  I have been using this display with PyMol and the stereo is 
great.  There is 
essentially no eye strain and no flicker at all.

the side by 
side stereo mode to work correctly.  Essentially the left and right images are

version.  
Here is the exact info from the DTI Technologies website:

To render side-by-side stereo (2:1 aspect ratio) which is compatible with any 
Virtual 
Window series display.

1. Prepare two cameras in your graphics or rendering application. Each camera 
represents each eye’s view. Render two scenes, one for the left eye view and 
one right 
eye view.

2. Squeeze the horizontal size of each image (1 left / 1 right) into half and 
place both of 
them onto one frame...

For example: If you are rendering 1024x768 images, you’ll will have two 
1024x768 
images representing a left/right eye view.

Each image is then squeezed, making them 512x768 images. These two images are 
then 
put onto a single frame, the left image on the left half of the frame and the 
right image 
on the right. So the final result is a 1024x768 side-by-side stereo image.

Any help would be appreciated.
