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.
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.
