transition shapes 2004-04-30 - By Andre DeAngelis

This is indeed doable Dave, and pretty easily for that matter.
When setting up a Slider parameter to go from shape A to shape B via shape
C, it just means setting relative values for the respective shapes and
linking their weights to the slider. What's even more neat is that you can
then go in and edit the relation F-cruves that are produced or if you
prefer, edit the expression that controls the relation.
This way you can effectively use a slider to control a whole sequence of
shapes - say a face going from happy to sad.
It's pretty amazing once you see it. Also, you might be interested to know
that XSI 4.0 alklows you to bake a shape animation seuqnce into a clip which
extends this functinality even further.
BTW. I never quite understood what was unique about the approach used to
animate Gollum's face and how is varied from the Transitio Shape approch.

In Maya, you can add an in-between target in blendshapes (shape animation)
so
that in transitioning from the base shape to a target shape, it passes
through
one or more other shapes on the way.
Last I looked at XSI, this wan't easily permissable. Maybe I missed
something or
maybe it's now possible.
I'm thinking about this after reading again about the many blendshape
approach
of Weta's Gollum, but then that's something different again. When combining
shape A and B, give me shape C instead.
