Physics Engine from Scratch

I built a constraint-based 3D rigid body physics engine and an ECS (entity-component-system) from scratch in C and C++. The physics engine runs on the ECS and uses constraints to model collision, joints, and motors.

This video gives a very high-level overview of the most critical pieces of the engine: the constraint solver, collision pipeline, ECS, and the editor. Everything mentioned in this video is open source, check out the links below!
