Degenerate triangles encountered

[Henry]

Hi everyone,

I was trying to use VMTK to find the centerlines of a 3D reconstruction, but it fails and produces an empty output file. This is the warning messages I get:

Computing centerlines...Warning: In /build/buildd/vtk-5.8.0/Graphics/vtkDelaunay3D.cxx, line 487

vtkDelaunay3D (0x3606a00): 125 degenerate triangles encountered, mesh quality suspect

Warning: In /build/buildd/vmtk-1.0.1/vtkVmtk/ComputationalGeometry/vtkvmtkSteepestDescentLineTracer.cxx, line 208

vtkvmtkSteepestDescentLineTracer (0x3c4eb50): Can't find a steepest descent edge. Target not reached.

Any suggestions?

Thanks,

Henry

Dear Henry,

could you share the surface with us?

Best Regards

Simone

Dear Henry,

the surface has connectivity problems and the resolution is quite poor.

I suggest to apply vmtksurfaceconnectivity and try to smooth the surface in order to eliminate the noise.

I tried but it seems very challenging to generate centerlines on that model.

Best Regards,

Simone
