Grasshopper surface from curves


There are random points and those points that are connected. All of these lines are triangular, and I want to make the surface that these lines create. I tried a lot, but some sides were not created… If you know how to solve it, please leave a comment. Please help me.

The picture below is made one by one using planarsrf on the Rhino. I want to make it like this.

Can you upload Grasshopper File??

If you so, it helps to solve the problem

here! I copied the algorithm on the Internet. But these points can be replaced by any random points like the delaunay things,

You can use cross reference to create all possible triangles with the curves and Boundary Surface to turn the closed curves into surfaces. The result is 29 surfaces.

Checking the collisions of the face normals distinguishes outside and inside surfaces. If a line along a face normal only has one collision at its startpoint then that face is an outside face.
