[vtkusers] vtk and opencascade

[Domenico 'Nico' Quaranta]

hi all,
I'm creating with visual studio 2012 and vtk (using activiz) for FEM analysis.
is there a way to read geometry data (like iges, step, parasolid) in the render window?
Is maybe opencascase the toolkit to do that?
if yes, how is it possible to handle vtk and opencascade in the same render window?
