[vtkusers] Volume Rendering Problem in ActiViz 6.2

[Matias Montroull]

Ok, I will answer my own question as I was able to figure out.

I had to change this line of code:

removepoints.SetInputData(contornos.GetOutput());
To:
*removepoints.SetInputConnection(contornos.GetOutputPort());*

Regards,

Matias.
