As I said, the alpha-shape might not be an algorithm that will fit your
needs. To simplify, the filtration of tetrahedra is based on their
circumsphere squared radius, and there is no guarantee to fit perfectly
your shape (which is why I suggested to try the demo and make the alpha vary to see whether you can get something good).

Hi Daniel:
Do you understand my point in my last email? I dont understand what you are saying, because I need to obtain something similar to Alpha_Shape class, where the triangulation adjusts the shape of my set of points. For this reason my image is bad and I dont desire these results.
Please, if someone has read my last email, give me some help, I dont know any more to do.
Best Regards from Madrid

Hola,

This bunny is quite a mess. Why don't you just plot the points, like
in bunny1? Perhaps
you got it right after all, and it's just a funny .off file.
Best,
Daniel
I have followed the first example in the charapter of
Alpha_Shape_3 and for this reason my code is very simple.

Please I need help, beacuse I dont know where I need to read
more details or waht kind of changes I need to do, please help.
May be my problem is when I create my resultant .off file,
because I could iterate my result in a wrong way.
Please any help will be very thankful
Best Regards
Juan carlos
