Object cover - image to refer

Hello is there a script I could use to adjust ? I am looking for a way to create an organic shape, which then I can apply a physical diagonal mesh to in with adjustable opening. The image shown this sense of disappearing, could this be done in grasshopper?
Any advice, links, script would help to start on it.

The Image shows a tree branching which is wrapped around a surface. There should be several scripts around branching in the Internet.
