Velcro Physics (Formerly Farseer Physics)

Warning: Under construction

The project is under development. Consider donating to support the effort.

What is this?

Velcro Physics is a high performance 2D collision detection system with realistic physics responses. It can be used to create games or real-time robotic simulations.

What is it good for?

You can create a game, robotic simulatons or even UI feedback systems using this engine and associated tools. Everything from a simple platform game to Marsrover simulations are possible.

Features

We have tons of features!

• Continuous collision detection (with time of impact solver)
• Contact callbacks: begin, end, pre-solve, post-solve
• Convex and concave polygons 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

Packages

You can use VelcroPhysics as a normal .NET library. We also have zero-copy integration with MonoGame.
