fold animatio (shape animation?) 2004-02-24 - By kim aldis

Shape animation does a straight interpolation between point 1 of shape A to
point 1 of shape B, so on for each point in the geometry so the corners of
your page are traveling in a straight line from 1 shape to the next,
resulting in the apparent shortening of the page size. I'm curious as to why
you don't think bones are up to the task, normally you get less control with
shapes, as you're finding. You could, I suppose, use an extra key shape in
the middle of the two you already have and force spline based interpolation
but if it was me I'd use 5 or 6 bones and turn the page with FK,
time-lagging the rotation of each bone to get the curve of the page. Help?
