This has probably already been done, but I can’t remember seeing it anywhere. I’ve writen a little script that can convert your active object’s loc/rot ipos into a 3d curve and a tracked empty. This is a beta release, and I made it primarily for editing imported camera data. The conversion is not at all perfect - ipos and curves deal with distance/time differently resulting in speed differences over the course of an animation. Also I haven’t added options for selecting tracking axis, etc.
Anyway, I think it is pretty useful even in it’s current state :eyebrowlift2:
