Bullet Cloth

Recently, I have been experimenting alternative ways of doing cloth effects. I always had an idea about using the points as simple particles or spheres while using the edges as constraints.

I didn't know how to set up hard constraints until I came across this post on the odforce forums:

This is the answer I was looking for. Now all I had to do was use the sim to drive the geometry in SOPs. I am really surprised haw fast it is. What makes it great is that it uses simple spheres as packed primitives with Bullet Solver.

Here are some demos:

You can easily set up pin constraints by setting i@active to 0.

For tearing, you set a Primitive Group, called broken, to the constraints. The tricky part is applying it to the rest geometry in SOPs.

 You could get some interesting results with the constraint network.
