Convert itk::PointSet to an triangular itk::Mesh

Hello everyone,

I have a 3D itk::PointSet that I need to save as an .stl file. My plan is to convert the PointSet into a mesh and then save it as an .stl file. However, I’m currently facing a challenge in defining the cells of the mesh.
I’m thinking about using the Delaunay triangulation algorithm. Before proceeding, I wanted to ask if this algorithm has already been implemented in the library, as I couldn’t find it in the documentation. Perhaps I might have overlooked something.

Thank you in advance!

I don’t think that ITK has a Delaunay implementation. Generally, ITK does not have a lot of mesh processing algorithms. It leaves that to other libraries, such as VTK. Take a look at vtkDelaunay3D class.
