Aether.Physics2D is a 2D collision detection system.
Documentation: https://nkast.github.io/Aether.Physics2D/
Web Demos:
- Continuous collision detection (with time of impact solver)
- Contact callbacks: begin, end, pre-solve, post-solve
- Convex and concave polyons and circles.
- Multiple shapes per body
- Dynamic tree and quad tree broadphase
- Fast broadphase AABB queries and raycasts
- Collision groups and categories
- Sleep management
- Friction and restitution
- Stable stacking with a linear-time solver
- Revolute, prismatic, distance, pulley, gear, mouse joint, and other joint types
- Joint limits and joint motors
- Controllers (gravity, force generators)
- Tools to decompose concave polygons, find convex hulls and boolean operations
- Factories to simplify the creation of bodies
