Generating a mesh from vtkPolyData in C++


I’ve tried using vtkGreedyTerrainDecimation but it doesn’t seem to work in alignment with what I am doing. Also, I am trying to use reconstruction methods that don’t require a remote library. Are there any suggestions? I tried drawing triangles following this example: individually but I didn’t get any triangles shown. Specifically, I am confused about how the SetId part works in alignment with the points.

Any help would be greatly appreciated. Thanks.
