How can I implement advanced collision detection in my C++ physics engine?

To implement advanced collision detection, you can use techniques like bounding volume hierarchies, spatial partitioning, or continuous collision detection. Which one are you interested in?

I'm interested in bounding volume hierarchies. How do I start with that?

Start by creating a tree structure where each node represents a bounding volume that encapsulates a set of objects. You can use AABBs or spheres for the bounding volumes.

What are the benefits of using bounding volume hierarchies?

Bounding volume hierarchies reduce the number of collision checks by quickly eliminating pairs of objects that do not collide, improving performance significantly.

Can you provide a code example for creating a bounding volume hierarchy?

Sure! Here's a simple example in C++ to create an AABB tree. Would you like to see the full implementation?
