Documentation and tutorial about Materials Nodes

Hi guys,
I found an example about material nodes on threejs official examples.

Diving into the code of the file I figured out a lot of new classes and concepts like: StandardNodeMaterial, TextureNode, Math3Node, SwitchNode that I have never seen.

Do you know any documentation, guide, tutorial or resourses to deep into these concepts and how they works?

Many thanks!

There is no documentation so far but it is planned to move NodeMaterial into the core. When this happens, I’m sure there will be a respective documentation.
