Hi Alex 

I have absolut no idear what structure they use inside , but it is not as fast as I could hope . 

I am struggling with speed issue , but I must say the result coming out is working. 

one thing to remember , the reason I try to use the cgal are because of the Curve/arc segment handling otherwise 
I think there are other packages  where u can gain more speed which support only lines. 

You mention BSP tree - I googled a bit , it seem to be addressed against game development ? am I right ?

If you are planing to use cgal for game ?   then I think you can drop that idear.
 
I have static graphic , and it take me very long time to calc. 

Best regards
Kim

Dear Kim

 

Thank you for reply. I have one more question.

 

All this operation is using what kind of method ? I found in Geometeric Tools book about BSP tree. So how faster it is ? Because i have lot of operation iterations.

In  CGAL other than Nef_2 package for Boolean operation ? 

 

Because in Nef_2 Package doesnot offere inexact arithmatic and also no floating points. It only support integer .

 

Correct me if i am wrong.
