I am getting the following error when marking up on a surface/model:
[VTK] vtkDelaunay2D (0000024030965F60): Edge not recovered, polygon fill suspect
[VTK] - Warning: Warning: In D:\D\P\S-0-build\VTK\Filters\Core\vtkDelaunay2D.cxx, line 1409
It is very reproducible with my own hi-res CT data, but I would not reproduce it with the sample CT data (head and heart). No problem with spline measurements.
Any idea what the error message mean or how to troubleshoot?
