Hi Matt, I don't know if this helps, but some of the stereo parameters (horizontal field of view, eye separation) can be changed interactively by mouse drag in the Side View tool, when the "View" in that tool is set to "top": <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/topview.html> I just noticed a messed-up sentence in that page I need to fix. For changing horizontal field of view, just drag one of the red lines and ignore the part about middle mouse button. Best, Elaine ----- Elaine C.

I am finding that getting the optimal stereo view requires ongoing adjustment of the stereo parameters, particularly when multiple people are observing the structure simultaneously (e.g., depthQ stereo projector). Currently these numbers have to be typed in, requiring me to break my gaze, move a mouse, and type a number. Ideally it would good to have controls similar to binoculars, such that you maintain constant view and adjust by turning knobs.

Getting hardware knobs may be impractical, but these improvements could help. 1) two small buttons (+/-) next to each stereo parameter. 2) commands that would do the same (small incremental changes). Then I could have my nostromo n52 USB game box dedicate the dual axis thumb button for stereo adjustment by issuing keyboard commands.

Thanks, Matt
