I need to make the model this effect! How should I achieve it?

Hi @ranwei-001. Sorry to see you have so many questions with no replies. You must be asking HARD questions. 🙂

I disabled line 78… just for fun… gets better edgeRender lines.

You sort-of need ONLY the edges to be rendered, and nothing else, right? hmm.
