[vtkusers] re: how to compute a curvature and normal of a point

[Moti Freiman]

Hi!

vtk has the class: vtkCurvatures which compute the mean and gauss 
curvature of a polydata. you can create polydata from your points using 
vtkDelaunay3D class.
there are some algorithms for computing the curvature. when i used the 
basic vtkcurvatures i have problems, so you need to be careful with that.
