How does collision detection work in C++ graphics APIs?

Collision detection in C++ graphics APIs typically involves checking for intersections between objects in a scene. This can be done using bounding volumes, such as spheres or boxes, to simplify the calculations.

What are the common algorithms used for collision detection?

Common algorithms include Axis-Aligned Bounding Box (AABB), Bounding Sphere, and the Separating Axis Theorem (SAT). Each has its own use cases depending on the complexity and requirements of the scene.

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 you can find such an axis, the shapes are guaranteed to be apart.

How can I implement collision detection in my game?

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