Dear Reader,
i’m looking for someone who can help me understand 3D math, this because i am trying/learning to build some complext shapes and cannot see the proper path of coding to get the job done
That’s a bit broad request, probably depends on the level you’d expect.
Vectors, matrices, and just some useful, practical 3D algebra to use with three? Always glad to help.

Theoretical explanation behind the .w within a quaternion on the other hand? I don’t think anybody really understands what it does there.

I would not formulate that in this generality.
Of course this is not elementary mathematics any more.
I was content with visualization.
