yeah ...
I still have a 'small' bug in there ...
The new created tetraedrons do not raise to the full height, and so they are
not regular...
But I don't think it will look better, if they did, because then there will
be some parts, that have coincident edges ...
It's hard to describe, but you can believe me ...
