Open CASCADE Technology provides functionality to reconstruct a NURBS surface from a cloud of points - you may use the nodes of triangulation as input points. The standard algorithm is implemented in the package GeomPlate. For its initial description, please consult the Modeling Algorithms User's Guide.

In addition, we offer a commercial tool called Surface from Scattered Points that provides advanced functionality of surface reconstruction. Please take a look at its description at
