R: Re: Contact detection
so you wrote from scratch the InsertionSortCollider... Why didn't
you choose to implement a grid collider? Do you have that algorithm written in
another language (e.g. Fortran)? Could it be possible to translate it in C++?
know that the best contact detection method doesn't exist since it is related
to to the problem to be solved, BUT there is no doubt that the grid collider is
better than the SAP one.
Honestly could you let me know me know if, within a
reasonable period of time, we will have the grid collider implemented in YADE?
Sorry if I guess but I am at the beginning of my D.Phil. and I am looking for
the "best" DEM code according to my needs.

Hehe. I'm sure Gallizzi read it before, and I read it before you too.

original PersistentSAPCollider & friends were purged from the repo
it was one of the worst code I've ever seen.)
