    1. Free-Form-Deformations (FFD's).

    Before reading up on this, make sure you know all about bezier curves & other parametric curves.... this is a tad bit mind blowing when you look at it.

    It basically creates a 3D volume around an object and will transform the points within it depending on how you transform the surface.

    2. Cloth (physical simulation)

    Model each vertex as a particle and use some nice complex physical model to work out the behaviour of the particles.

    These are both quite challenging though....
