Physics Sandbox

Build a 2D physics engine with rigid body simulation, collision detection and response, constraints/joints, gravity, and interactive object spawning.

physicsenginesimulationcanvas

Objectives

Implement rigid body dynamics (position, velocity, acceleration)
Build collision detection for circles and rectangles
Add collision response with restitution and friction
Implement constraints and joints between bodies
Create an interactive sandbox for spawning objects

Hints

Start with simple circle-circle collision
Use the Separating Axis Theorem for rectangles
Verlet integration is simpler than RK4 for beginners
