Thank you very much, Pierre!

 

In fact this give me a good approximation of the area.

Assunto: Re: [cgal-discuss] Area and stream lines

hi Marcos,

I think that's feasible if you go into the streamline code:
- add integer attribute to the DT vertices and update it during integration - one index per streamline
- iterate over all triangles which have only two distinct streamline indices (say index i and j) - and add their area - you should have a decent estimate of the area between streamline i and j.

Hi, everybody!
Is possible to calculate the area between two stream-lines?

 

Thanks!
