Cloth Simulation

A real-time cloth built from a grid of point masses linked by distance constraints. It uses Verlet integration — positions carry their own velocity — and relaxes the constraints several times per frame so the fabric holds together while still swinging and stretching under gravity.

• Verlet integration — Velocity is implicit in the previous position — stable and simple.
• Constraint relaxation — Each thread is solved a few times per frame to keep the weave taut.
• Drag & tear — Pull the cloth around, or switch to Cut mode to slice through the threads.
