[vtkusers] Concave Polygons

[Mario Richtsfeld]

Dear All,

 

I want to calculate the inner centre of mass of different polygons that
includes also concave polygons.

 

The function: ->GetCenter() only returns the physical midpoint, but I need
the centre inside the polygon surface.

 

Or, exist a way a way to use the vtkImageSkeleton2D filter?

 

The PowerCrustAlgorithmn is very unstable for my application, because I have
only the boundary points.

 

Thanks for every help!

 

All the best!

 

Mario
