[vtkusers] Comput the area contained by a contour (VTK C++)

[Rodrigo Lovera]

Hello everyone,

I was wondering if any of you know a method to compute the area cointained
by a figure or maybe something like the contourwidget which shape can be
changed at will.

What I need -d be some kind of implementation or code or guide on how to
perform that math operation, similar to the distance widget but what I need
to compute now is area.

Id really appreciate any kind of help
