I have come across MITK’s “Movie Maker” widget and it is quite nice. It mimics animation editing in Powerpoint - quite simple and intuitive. It does not support keyframes but allows timeline editing.
We could share this component between MITK and Slicer via CTK as we do it with many other widgets.
@pieper drafted a prototype for keyframe editor (https://github.com/pieper/SlicerAnimator)
We need the keyframes to edit the transfer functions, but perhaps there might be a way to combine them.
Yes, the SlicerAnimator extension is a first pass, but it covers a lot of our target goals, like integration with mrml and sequences, extensibility, pretty simple to use, etc. I’m planning to polish off a few of the things listed in the issues, but then wait and see if we get some more development resources.
The main code for SlicerAnimator is now located at:
