[vtkusers] VTKboolean smoothes the results! Any other libraries for boolean operation on polydata?

[Majid Mohammad sadeghi]

Dear Cory,
Thanks for the reply, I set the actors property to  SetInterpolationToFlat(); as you said, but the result is the same I put a picture before and after boolean operation here. Any suggestion? Are you familier with any other library? Current boolean operation takes about 150 seconds on my system, do you think this is normal?

What do you mean by smooth? The lighting is smooth? I think the filter
may be adding surface normals, in which case any actor for the data
will turn on Gouraud shading (or maybe Phong) by default, which will
make your surface look smooth. You can turn off smooth lighting as
shown in this example:
