I have a set of 3d points defining a polygon A, and a set of points defining polygon B. All these points are planar, and A is actually a loop within B.
My question is: how can i generate a triangulated polygon with hole? ie. the green region on the right.
I tried the code above and encountered an empty result. After a bit of toggle I found that the root cause is I forgot to set the lines of polygon’s polydata. For anyone who needs to do the same, remember to set the lines before using vtkContourTriangulator.
