[Chimera-users] hardware stereo switching between distal and proximal when rotating

My guess is that the problem you are having is that the focal plane,
basically where the molecule intersects the screen, is too far back, so
when parts of the molecule are far out of the screen, your eyes are
having problems converging, and you're getting an inversion. To test
this hypothesis, bring up the SideView tool, and switch to the "top"
side view from the "right" side view. You will then see a dashed line
that represents the focal plane. Drag the focal plane all the way to
the near plane (the solid vertical line closest to the eye), and then
try your rotating experiment again. And please let me know if that is
really the problem you're having.
Automatically managing the focal plane in stereo is something chimera
needs to do, and there is experimental support for that if you run the
following Python code (either in the IDLE window, or place it in a .py
file and open the python file within chimera):
chimera.viewer.camera.autoFocus = True
But not all parts of chimera respect that setting, so it is still
possible for the focal plane to get out of whack and you'll need to
adjust it by hand.
