[vtkusers] displaying simple polygons

[Xavi Almolda]

Hello,

I am developing an application with vtk that shows different results in the
form of a mesh with values at the nodes or elements. The problem is that I
need to draw some simple polygons on top of the results.
I need to draw some simple polygons that represent spatial features, like
the fetaures from a GIS layer. Each polygon is defined as a set of
coordinates ( only x and y coordinates ).
What is the best solution for doing this with vtk?

Thank you,

Xavi
