Ammo.js Bullet Physics
Ammo.js is a JavaScript port of the Bullet physics engine. Use it to simulate gravity, collisions, constraints, and rigid-body dynamics in WebGL games or Three.js projects. Advanced: soft bodies (cloth, jello), ragdoll physics, vehicle simulation. Career path: game engineer → physics programmer → simulation specialist. Niche skill: only 5-10% of developers, but essential for physics-based games. Salaries vary widely depending on game studio ($80k-200k+).
What is Ammo.js Bullet Physics
Ammo.js is a JavaScript port of the Bullet physics engine (a C++ library). It enables real-time 3D physics simulation: gravity, collisions, rigid bodies, constraints, and soft bodies. Used in WebGL games, 3D visualizations, and interactive experiences. Typical workflow: create physics world, add bodies (cubes, spheres, custom meshes), apply forces, let Ammo.js simulate collisions and gravity, synchronize 3D mesh (Three.js) with physics body.
