How do I implement collision detection in a C++ physics engine?

To implement collision detection, you can use bounding boxes or spheres to simplify the shapes of your objects.

What are the different types of collision detection methods?

Common methods include Axis-Aligned Bounding Box (AABB), Oriented Bounding Box (OBB), and Separating Axis Theorem (SAT).

Can you explain the Separating Axis Theorem?

The Separating Axis Theorem states that two convex shapes do not collide if there exists a line (axis) on which their projections do not overlap.

How can I optimize collision detection for many objects?

You can use spatial partitioning techniques like quad-trees or octrees to reduce the number of collision checks.
