@kreg i realize you're using godot but i find a lot of times indirect information is just as helpful sometimes. that said, i don't know if you use blender but @erindale is a math master when it comes to all things vector. i bet some of his tutorials would help break things down. i bet the knowledge gained would carry over. i'm not a great math person really and often just stumble through things otherwise i'd give you better answers hahaha. follow erindale though. good person. good info.
