Math Teacher or TD

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. :smile: (jan@wtlstudio.com)

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

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