More specifically, I'm looking for ideas on how to simulate a
parachute stuffed into a tube.
They are usually two colors, picture a hemisphere, painted with
checkerboard (close enough for government work anyway).  The deployed
version isn't a problem, but the "stuff in a tube" version has me
stumped.  I haven't been able to figure a method that looks anything
like real.

Tried that, it comes out looking like a patterned tube, rather than
fabric stuffed into a tube.

How about a mess of a mesh?
For instance, you could do the same as happens with the parachute:
create a mess of an object (sphere, box, whatever) but built from a lot
of triangles. Than translate all points of the triangle to fit within
the tube (randomly), without ripping the mesh apart.
Perhaps add some wrinkles to the texture to cover up some strange
faults.

Good luck,

Remco

  It's a bird ! It's a plane, It's Super Patch !
Bezier patches might get you there or you might try
a little csg action on a cylinder and rotate multiple
copies of it around inside the tube.
How about a cylinder smaller than the "stuff" tube that
has an image map of pleated house curtains.
    Or take your full size chute and use the Chris Colefax
object bender inc file and neatly fold it up until it fits
in the tube or ....

I like this last approach best. (plus I don't have any curtains in my
house in purple and yellow!)
Does this imply that I can algorithmically un-fold it?

 I think that question could be better fielded by Chris Colefax.
Which means I don't know.
