Hello readers, I’m no longer posting new content on gafferongames.com Please check out my new blog at mas-bandwidth.com! Introduction Hi, I’m Glenn Fiedler and welcome to Game Physics. In the previous article we discussed how to integrate the equations of motion using a numerical integrator. Integration sounds complicated, but it’s just a way to advance the your physics simulation forward by some small amount of time called “delta time” (or dt for short).
