Re: Particle Generation (how to avoid explosion)


Hi Vaclav, 

Thank you for your suggestions, Frederic made the same remarks.
Concerning the use of SpherePadder (geometric algorithm), I will write a
detailled documentation in the next months.
For the moment in few weeks, a second paper will be available in order to
explain the algorithm method and show examples of engineering applications,

In the meantime, the geometric algorithm still requires some developments
to be fully userfriendly as you say it. 

keep in touch

That is not finished implementation. You use some obscure makefiles
(should be integrated with scons) and there is no documentation. Care to
fix that please? (I manged to compile that but am I supposed to read the
source to use it?) There is some python interface in
SpherePadder_wrapper.cpp, why don't you provide a simple showcase script
and sample data to run it on?

If you depend on cgal for triangulation, IIRC Bruno was going to ask
them about the license issues.
