A quick post to summarize the posts I’ve already made on physics engines. The series are not yet done. I will cover the broad and narrow phase algorithms when I get around to write about them.Part 1 – The very basics of physics engines. What is the responsibility of a physics engine and how are they defined.Part 2 – A quick overview of how a physics engine work. Collision detection, physics response and their submechanisms.Part 3 – A look into the physics response part of a physics engine. How do we calculate velocity and how do we apply it using numerical integration.
