Zach,
Can you wait a week or two? This sort of thing is about to get 100X easier in
PyMOL...
Cheers,
Warren

Subject: [PyMOL] Animation/ Matrix Question
Hi,
I would like to create a movie where my molecules are moving at the same time
that the camera is moving in/around/though them.
I have been using Slerpy to get the movement effects that i would like but I
would also like to make the molecules undergo translation/rotation functions
relative to one another. Slerpy also has this capability but limited for what I
would like to do. Using the Slerpy 'saction' command I can have the option to
change elements in the scene but then Slerpy will interpolate 50 frames until
the next shot and I don't get to coordinate my molecular movements with my
camera movements. I can approach this if I shorten the default frame number in
slerpy (take steps of 5 or something like that) but then I don't get to take
advantage of Slerpy's smooth camera motion.
Although there may be many ways to do what I would like to do, does anyone have
any experience with outputting the view matrix (get_view) for each of
slerpy's camera positions? If so, I could do a dry run with Slerpy, use
get_view to output the view matrix and then combine each view with a
rotate/translate function in order to get the effect I am looking for. The only
problem is that I haven't figured out how to do that. Perhaps someone on this
list already has?
Hmmm. I think the most logical way would be if there were some script that
could get_view for each frame of the final movie. Any help/suggestions would be
greatly appreciated.
best,
zach cp
Thank You Warren; Pymol is a great program and the PyMolWiki has become a
fantastic resource for newbies.
