[vtkusers] how to determine Holes in Polydata ?

[vikrant aglawe]

Hi,

I am currently trying to decimate a given topology using vtkDcimate pro
filter.

In order to achieve required reduction I had to turn the topology
preservation flag OFF and boundary vertex deletion flag ON, which,

according to vtk documentation, can generate holes and nonrectangular
surfaces. Is their a way to determine
if holes occur in the process of decimation or when the boundary becomes non
rectangular?
