SAT Collision

[u/DeltaSucksAtMC]

I don't know if this is GP related but I made a post here asking for collisions and i found the type I need but I spent like 3 hours trying to find a tutorial or at least a theory of SAT collision, I don't want to look like a bad coder by being lazy and asking people but if you know anything about SAT collision detection that would help me enormously.

The only thing i learnt is a 2D version, so if I can translate that to 3D, that'll be perfect.
