[vtkusers] Display a filled semi-transparent contour?

[Oleg Krivosheev]

Hi, All

currently I'm displaying contour coming as vtkPolyData in the
vtcContourWidget and use vtkOrientedGlyphRepresentation.
So it looks like set of points connected by smooth spline lines,
editable, could set color, pattern etc.

Is it possible to display such closed contour as filled
semi-transparent (with some user-set alpha) one?

Any help or pointer would be greatly appreciated

regards

OK
