hi.  
I created a polygon using vtkPoints. And we want to make it a boolean. What should I do?  
I guess vtkBooleanOperationPolyDataFilter doesn’t work.

Hello,

Can you, please, present in more details what is wrong? Or perhaps some figures showing the problem. Posting some code often helps too.

regards,

Paulo
