Hi Arne, The surface integral is the same as the surface area if the scalars on your surface are constant. So you would use vtkContourFilter to generate an isosurface of your distance map at an isovalue of 0 and then use vtkMassProperties to calculate the surface area of the resulting polydata. That should give you a discrete approximation.  karthik On 3/7/07, Arne Hansen <bsd.diverse@...> wrote: > > Hello.
