Real-Time Physics Simulation Forum

In Baraff's paper he glosses over how to introduce hinges. For example, a door. A second example is say two sticks hinged together floating through space. Could someone give me a detailed explanation of how to add these two examples in?

In more detailed what I don't understand is how these examples fit into the overall physics engine. I thought that with the approach in Baraff's papers that the loop is

integrate
process all collisions
process all resting (or sliding) contact

So how exactly does my second example get processed in this? How does the first example get processed in this?

I recommend looking here:

Kenny Erleben PhD thesis:

Erin Catto:

I strongly recommend looking at the ODE source code:
