[vtkusers] After a threshold need render opacity.

[Francois Louis LAILLIER]

Hello vtkusers.

 

I create a volume with binary files, I threshold it, now I want render
the black pixel transparent.

I think If I put their opacity = 0, I will have the good result.

 

 

But I don't understand argument of vtkpieceswises

 

When we add a new point like : opacitytransferfunction.addpoint(a,b)

 

What are the two arguments?

 

Do you think that it is possible to render transparent the black pixels,
and are they invisible on every rotation?

 

Best regards, Francois Louis.
