I want to draw a sheet, which can be twisted in any angle, my question is how to caculate the control points?

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....
