comment Continuous Physics Engine's Collision Detection Techniques
So for secondary broad phase detection, are you suggesting I get the midpoint of the circle's travel path, and test if it is inside the circle being tested against? I was thinking I could simply create an equation that gives the two circles distance from each other over time, and seeing if at any time the distance equals 0.

comment Collision filtering techniques
I was thinking about this myself, but instead of an octree, I thought I would just store filter data in each body as an unsigned int, and make each digit of the overall value a different depth into the "tree" of digits. I don't know if this would be slow or memory-sucking though.

Wow this looks like a really good approach actually =D, would there happen to be a name for this technique?

This helps for other aspects of my physics engine, but not the question =D. Look at my response to your comment

@xixonia take a look at the example I updated, basically want ways for a user to easily specify some complex relationships between bodies (what should/shouldn't collide), and ways to organize that filtering data so that it's easily attainable / memory-efficient.

@bummzack :Yes, I did consider this, but how would you accomplish something such as my example stated above only with a simple set of groups? (look at the new text added under it)

Excellent resource, I'm also looking for a way to simulate elasicity without springs however, for instance look at this paper: matthiasmueller.info/publications/…
