About

You can check the WEB version here. It is a port using WASM generated by Emscripten using WebGL on the browser.

• Restricted only to circles
• Supports gravity
• Supports collisions
  • Implements a Quadtree for collision detection
• Supports constraints
  • Implements both a circle and a rectangle world constraint
• Supports user interaction
  • Dragging
  • Spawning
  • Explode
