Hey there,
I have 2 problems with curves projection which I could not figure out a solution. Would appreciate if someone could help me out with one or both (Grasshopper solution preferred, if possible):
1.) Is there a way to do a project curves onto a plane using “obstacles” in the way which block/consume the curves like if it was light?
What I mean is something like that:
What I am actually interested in is the curves on the plane - so not getting the curves on the blocking cone would be ok:

2.) When a closed curve (here in yellow) is projected onto a plane it also produces a closed curve (the blue curve). Is there a way to only get the “visible” open curve - as it looks like:

Any hint to existing previous posts also appreciated.
