I would like to see an example of this, if possible. I can envision what you mean, but how much movement is there? -- perhaps it is an acceptable amount? Sometimes small defects such as this can be hidden (i.e., human eye distracted) by the move or moveTo command, which is, after all, the next thing that is going to happen.
Frieda,
I added a switch to enable this change in 'center' behavior
set frieda on
Wow. My very own command! :->
It is checked in.
Q: Can you build from the cvs source?
No, unfortunately I cannot.
Q: Frieda, remind me once again what you are trying to accomplish ...
I usually fade out sections of a macromolecule to focus on one part,
and ideally I want that one part to move to the center of the applet in
a centered fashion, not as if the rest of the molecule were still
there. (Which it is of course but it is unseen).
In other words, I use a Chime move (or in Jmol moveTo) command to
smoothly bring the remaining section of the molecule to where I want it
- usually in the center of the applet, with the relevant "face" of the
section shown to the viewer-- the rotations that occur in this move
revolve around the new center, not the whole molecule.
OK
Be advised that the moveTo command probably has bugs when the center has
been moved.
Ah. Hmmm. Do you think these will be intractable?
As a second choice, I would move the molecule to its new position
without rotations, and once it is in position, then do the rotations so
the relevant face is in front. That would mean that the act of
centering would not take place until the molecule is in it's new
position in the center of the screen.
OK, let me think about one of these options and about the possibility of
shifting the center to the center of the applet.
OK.
As I have thought more about this, the "second choice" I describe above appears to me to be a very distant second. I suspect that it would distract the viewer, and lack the impact and intuitive "sense" of the more sophisticated move.
