What is AABB - Collision detection?

Question

Hi I\'m making a voxel game in Java and while researching all the different things I\'d need to learn, I noticed that a lot of games use AABB

Answer 1

Axis Aligned Bounding Box

Basically its the smallest Cuboid that can completely contain the shape, usually defined by a pair of 3d co-ordinates.

It's very fast to check for collisions between two AABB as all you need to do is check the range of the X, Y and Z values for the corners.
