Do you think recalculating a bounding tree after every simulation step 
will be faster in the end?

It would be possible to speed up the triangle function a bit since we 
don't actually need its value if it exceeds the mass radius of course.

To speed up collision calculations the mechsim patch has the possibility 
to group masses and only enable collisions between masses of different 
groups.
