[Chimera-users] matrixget/set, keyframes, and interpolation

[Jonathan Hilmer]

Does anyone have experience making movies in Chimera used more
advanced motions, besides the standard roll, rock, etc?

My general idea is to use matrixget to output a series of matrices,
interpolate them in my standard Python environment (which is related
to the question from Vol 38, Issue 10), and create as output a Chimera
script composed of hundreds of 'matrixset' matrices.

The Python Computer Graphics Kit (http://cgkit.sourceforge.net) will
give me the functions for quaternions, as would ScientificPython or
pythonOpenGL, but a quick review of their documentation suggests that
in any package it will be necessary to interpolate the rotation
separately from the translation: obviously it would be more convenient
if there is a package that can transparently interpolate the matrices
as provided by Chimera.

Has anyone gone through this issue before, hopefully with some tips for me?

Thanks,
Jonathan
