In sintesi

Cannon.js is a JavaScript physics engine for simulating rigid body physics (gravity, collisions, constraints). Used in 3D games, simulations, and interactive 3D web apps. Salary impact is high because physics expertise is scarce and well-compensated. Learn in 3-4 months. Sits between 3D graphics and game-physics simulation.

Cos'è Physics Engine Cannon

Cannon.js is a JavaScript physics engine that simulates rigid body physics: gravity, collisions, friction, constraints (joints, hinges, springs). You define physical bodies (boxes, spheres, cylinders), set their properties (mass, friction, velocity), and Cannon simulates how they interact. Cannon powers physics in 3D web games, architectural visualizations, simulations, and interactive 3D experiences. It integrates with Three.js, Babylon.js, and other 3D libraries. It runs on the GPU via WebGL, so it's performant for web.

❓ Domande frequenti

Is Cannon.js good for professional physics simulation?
Yes, for web-based simulations and games. For cutting-edge physics (cloth, fluids), specialized engines are better. But for rigid body, Cannon.js is solid.
How does Cannon.js compare to built-in physics in game engines?
Babylon.js and Cesium.js have integrated physics (Cannon-based). If you're already in those engines, use theirs. If you need custom physics in Three.js, use Cannon directly.
What's the performance impact of realistic physics?
Cannon.js can simulate ~1000 objects at 60fps on a decent GPU. More with optimization. Profile early to find bottlenecks.
How do I debug physics issues?
Cannon provides a debugger (CannonDebugRenderer) that visualizes bodies, constraints, and collisions. Visual debugging is essential.
Can I use Cannon in Node.js?
Yes. Cannon runs server-side for server-authoritative physics. Useful for multiplayer games where server validates collisions.
