Frieda, You have requested an option that the behavior be changed when the 'center' command is applied. Optionally, you would like to have the molecular model stay in the same position, but the center of rotation moved.
I have done some work on this and can report the following: I have a prototype operational, but the results are unacceptable. The problem is caused by 'perspective depth' calculations. That is, if we 'set perspectiveDepth off' then everything works OK. However, with perspectiveDepth turned on (the default) then the perspective view of the model changes when the center of rotation is changed. That is, because the new center of rotation is not the same as the old one, the view is different. You can think of the difference as moving the focus of the camera ... it is almost the same, but not exactly ... so there is movement. I do not see a solution to this problem, other than turning off perspective depth. (Turning off perspective depth would solve some other problems too, but I think that we would lose something and that turning it off would be short-sighted.) So, let me ask two things: Q: Frieda, remind me once again what you are trying to accomplish ... Q: Any thoughts/suggestions/ideas from anyone else would be appreciated.
