Verlet (Physics Transform)

Verlet integration is a lightweight physics simulation method commonly used for simulating soft-body motion, cloth, hair, tails, and other physics-driven transforms. Named after physicist Loup Verlet, this approach calculates object motion using position and velocity approximations without relying on forces or rigidbody components.

In this system:

• Each VerletTransformNode simulates a transform’s motion using Verlet integration.

• The system is ideal for creating stable, springy motion with low performance cost.

• Parameters like drag, damping, elasticity, and stiffness are controllable with artist-friendly curves.

Unlike Unity’s built-in physics, this system doesn’t use Rigidbody or FixedUpdate. It’s fully decoupled and works on arbitrary Transform hierarchies — making it ideal for stylised secondary animation, procedural motion, and non-physical entities.
