How does 3D collision detection work in C++?

3D collision detection in C++ involves algorithms that determine if two objects intersect in a 3D space. Common methods include bounding box checks and more complex algorithms like the Separating Axis Theorem.

What are the common algorithms used for collision detection?

Some common algorithms include Axis-Aligned Bounding Box (AABB), Oriented Bounding Box (OBB), and the GJK (Gilbert-Johnson-Keerthi) algorithm for convex shapes.

Can you explain the Separating Axis Theorem?

The Separating Axis Theorem states that two convex shapes do not collide if there exists a plane (axis) that separates them. If no such axis exists, the shapes are colliding.

How can I implement collision detection in my game?

You can start by defining bounding volumes for your objects, then use one of the algorithms mentioned to check for intersections during each frame of your game.
