Integrating Physics-based Animations with Theater.js and Three.js

Introduction: Theater.js animations can be combined with physics engines like Cannon.js to create more realistic animations with control over scripted sequences.

Implementation: To animate an object falling with physics while maintaining script control:

const body = new CANNON.Body({ mass: 1, shape: new CANNON.Sphere(1) });
world.addBody(body);

theater.addActor("ball", { position: { y: 10 } });
theater.getActor("ball").play({ position: { y: 0 } }, { duration: 2000 });

Conclusion: Blending scripted animations with physics-based motion allows for natural, dynamic animations in Three.js applications.
