Summary: Spin using mouse

Initial Comment:
I showed Jmol to a colleague in IT and he was very impressed: The one thing that disappointed him was that when using the mouse to rotate a molecule, you can't use the mouse to set the molecule spinning. I think he was expecting interaction like Google Earth...

Would it be possible to use the rotation of the molecule (at the moment the mouse was unclicked) as a new set of spin parameters?

1. On second thought, too tricky.  It wouldn't be the default, and it
might take some significant explaining to a user how to do it, as it won't
be intuitive if they have any experience with Jmol. 

2. It's just eye-candy.


I'm going to close this unless someone really wants it.

Without having any solid experience on these behaviours, I would say:

1.- A script command to activate this non-default mode is the sensible
choice.
E.g.: "set persistentRotation on" or "set gestureSpin on"

2.- Does the speed of mouse motion determine the spin rate then?  
Yes, if feasible.

3.- How do you stop the rotation? 
Just by clicking (on the background, or even also on the molecule) seems
intuitive to me.

4.- Is the rotation internal?
I think both options could be expected by a user. Just decide on one;
internal looks good. Or, have a switch on the initiating command to decide
which modality will be used: "set gestureSpin { on | internal | external |
off } "

great idea. We could certainly set up a mode for this; probably not the
default mode, though. Questions:

How do you control it?

Does the speed of mouse motion determine the spin rate then?

How do you stop the rotation? 
Is the rotation internal to the molecule (around its axes) or based on the
window? That is, if I were to further manipulate the model, would I see the
model spinning around its same axis, but this axis is now pointing in a new
direction? (I suppose since the Earth rotates "internally" this is what you
had in mind.)

Should be a piece of cake to set this up. Mind you, most chemists do NOT
set molecules spinning. This would be "just for show", thus not the
default.
