I find that clipping planes for globe and models can only cut a convex area.
What if I have a concave shape to clip?
My solution is to apply multiple clippingPlaneCollections.
So that I can triangulate the concave shape into triangles first, and then clip the area triangle by triangle with multiple clippingPlaneCollections.
However, modifying the source code is a little bit hard for me.
Can any help me with the idea?
