Hello Christian, I would say it will be faster in c++ (as almost anything :-). Esepcially here you can save a lot of time by changing allocation of new Vector3r object for each particle to just rewriting doubles.
As the place I would use Shop.*pp file for c++ code and utils module for python interface (if nobody else disagree). regards Jan 2012/7/18 Christian Jakob <[email protected]> > Public bug reported: > > Hi, > > I need a "calm function" for my generation process.
