Cloth Simulation (2D)

This 2D simulator builds a piece of cloth from a grid of point masses joined by structural, shear and bend springs, then advances it with Verlet integration under gravity and a gusting wind field. Drag any part of the fabric with the mouse to see it swing and settle, switch to the tear tool and cut through it to watch the rip propagate along whichever threads are carrying the most tension, or raise the tear-resistance slider to make the fabric tougher and the stiffness slider to make it hang crisper instead of floppy.
