Hi Boris, You could try adjusting the field-of-view angle in the perspective projection. This can be adjusted with command “set fieldOfView” or in the Camera tool (one of the tabs in the same GUI as the Side View). <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/set.html> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/sideview.html#camera> I hope this helps, Elaine ---------- Elaine C.

Thanks Conrad - has this always been coded this way? I seem to remember that I used orthographic mode (years? ago) when the perspective mode overemphasized depth - which is what I was trying to solve in the first place.
Thus the workaround seem to be to increase the distance to screen in orthographic mode - something like 80cm gives me about the right depth-to-width ratio on B-DNA.
Cheers, Boris

Stereo views derive from binocular vision where the left and right eyes see slightly different orientations of the same scene. Perspective projects approximates the positions of the two eyes and generate two images that differ by a shearing transformation, and you get the stereo effect. Orthographic projection effectively places the eye infinitely far away in the viewing direction, so the views for left and right are identical, and you do not get the stereo effect. Thus, stereo viewing and orthographic projection are inherently incompatible and should not be used together.

Hello - When viewing a molecule in wall-eye stereo and orthographic projection, the scene is "flat", i.e. the L and R images are identical. Perspective projection works as expected. Is there a workaround? Chimera 1.12 (41617) Mac OS X 10.11.16, NVIDIA GeForce GT 750M Thanks! Boris
