[vtkusers] vtkActor2D / Polygons

[D. Vercauteren]

Hi VTKers,

I've tried to change the opacity of an Actor2D with no sucess. In a mail found on the list  it's explained that it's not implemented in vtk2.4. It seems it's not in the nightly neither. Is it planned for the upcoming official release ? Or is it ok in the nightly and I'm just missing something ?

Another one : when building a polygon, if it's convex all works fine. If it isn't convex, it seems the triangulate method which fills the polygon just pick a point and triangulate from it. So the filled polygon has a strange shape with triangles overlapping the real one. Is there a way to have it work ?
I've tried to pass the polygon through vtkTriangleFilter but it's exactly the same problem.

Thanks

Damien
