CCD/equivalent for fast moving kinematic objects

Post by sitnduck »

Hi!
I am considering using Bullet as a quick way of implementing collision detection (not motion simulation) and would like to know if it is possible to do the following. I looked around and it FEELS like it's possible, but I would love to get confirmation that the specifics are possible.

Basically, implement all movement "manually" so simply use kinematic objects. Then use Bullet to detect collisions from frame to frame. My objects move very fast relative to one another, so I would like to make sure:

-CCD (or some other reliable method) can be used with kinematic objects with objects moving at high speeds
-It is possible to extract the "first" collision that happened in the last frame (I assume I will get a bunch of contact points with a timestamp or something like that?)

Thank you!
