I've looked around and everything I've found (vtk, cgal, pcl) only do a surface reconstruction which ends up generating its own points to triangulate. I want to actually use the points I have as the vertices of the triangulation. Along with the point locations, I have a lot of information available in my code that I could provide:<br></div><br>Normal vector at each point<br></div>Bounding segmented curve(s) (i.e., lists of edge cells indexing the list of surface points)<br></div>A polydata representation of the surface (Note that the points I want to triangulate are distinct from the points involved in this)<br><br>The only vtk utility that seems to come close to this is vtkDelaunay2D,
but it's only useful if all the points can be mapped to a 2D plane. This isn't possible in general without a parametric surface, which is one bit of information I don't have.<br><br></div><div>Thanks in advance for the help.<br></div></div></div></blockquote></div>
