THREE.JS / FOUNDATIONS / AMMO ROPE

A rope carries the motion.

This native Ammo study follows the pinned soft-body rope example: a 10-segment rope is anchored to a ball and a motorized arm inside a soft-rigid dynamics world.

Q/A also move the source-style arm motor. Step and sampling controls are deterministic so the rope state can be inspected without claiming exact official page or whole-example fidelity.

Direct Ammo bindings are used because the installed AmmoPhysics helper does not expose soft-body creation or anchor APIs.

Based on the pinned official Ammo rope example. This is a native behavior lab with deterministic controls, not a claim of exact official page, texture, Stats, pixel, device/perf/stress, or whole-example fidelity.
