Here we go. Five hours of fiddling around with vector arithmetics, I finally
ended up with this and then soon noticed, that I could have gotten it
earlier if I hadn't been to focussed on a certain approach... Ah, well. At
least it's done.

Now, you can pick a direction at which you want to drop the snow (and create
the orthographic view with). The image was created by dropping snow from
above and right (-x-y is the direction then: left and down). Used some
higher settings than in the last one to see if the branches' tips get
properly mapped, and as far as I can tell, they do (mathematically, they
should, anyways). 3m20seconds to create 68.000 surface points.

Teflon was still not invented... ;-)

Tim
