Wow, this is really impressive!

I don't recall in what program you make the simulation. Ultimately I hope it
can be implemented in POV-Ray as a patch, if that isn't what you're already
doing.

Now, I know it's very ambiguous, but IMO to make the cloth simulations
really useful for a wide variety of animations, three things are needed:

* Any points on the cloth can be "control points", i.e. points that you can
control and attach to things in scene. For example, in this animation it
seemed like the two upper corners were control points, or maybe the entire
upper edge of the cloth (it was a bit difficult to see). But I hope it can
be possible to make any point a control point. This is probably not too
difficult; maybe your system can already do this.

* Collision detection with any object in POV-Ray. And the objects should be
described in normal POV-Ray syntax. This of course is only possible if the
cloth simulation is made as a patch. This would increase the possibilities a
lot!

* And the most difficult: Instead of the cloth always being a square piece,
it should be able to be any form. I don't just mean any flat form, but
really any form. The most extreme form of this would be if the simulation
could take any mesh as basis for the shape. I know it will be extremely
difficult creating a system that will automatically figure out where to
place all the strings, and just to keep track on them when there's no real
order in the grid. However, if this or something similar is done, the system
could be used to simulate real clothes. Clothes, and not cloth, is in my
opinion one of the ultimate goals for a simulation system like this.

I don't expect you to do any of this, it's just a few long-term visions that
I think could be cool... ;)
