No i am not trying to make game :) .. I am working on 3D construction project from 2D images silhoutte.

 

How is your speed results ? Which kernel you had used ?

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.

Hi

 

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.
