Triangulate a surface with vtk from points AND normals

Question

I have a set of points in 3D that lie on a surface and I also have the normals at every point. I would like to generate a surface triangulation with this information. In addition I could tell the algorithm to use what points lie on the boundary if that is needed.

So, I have quite a bit of information: * points * normals * boundary

How do I triangulate a surface with this information using vtk?

A surface reconstruction algorithm is like using a bomb for this problem since I have all this information that I would like to use. This information comes from a simulation so I know the surface exists and that is quite smooth.

I would like the answer to be cast in terms of either what vtk function to use and if available (and that would be great) examples using this function.

Thank you so much in advance.

Answer 1

You can use the vtkSurfaceReconstruction filter to create a surface from a set of 3D points.

Answer 2

You could try the point cloud library
