Hi! I hope you're having a great day : )
I currently working on my first serious 3D game engine using C++ and OpenGL, yeah, I know, I should use a premade one but I'm crazy ; )
I've finished the very first part of the engine (which is some 3D shapes with basic transform), now, I want to start implementing a basic 3D collision detection system just so I can make playable content with this engine, I do plan on upgrading it in the future. But now I would love some suggestions about how can I even start …
