[Insight-users] How can I triangulate or polygonalize a 3D point set data ?

[Sylvain Jaume]

Hi Cem,

You could use vtkDelaunay2D or vtkDelaunay3D and vtkPolydataToitkMesh in 
InsightApplications/DeformableModelSimplexMesh/. You can constrain the 
triangulation of the vtkDelaunay2D using SetSource. To export a VTK 
scene into an .obj file, use the vtkOBJExporter.

Regards,
Sylvain
