Kena!

I tried to create something like that (for hair approximation) by using
same approach (tracing to object's surface from its center) last year,
but failed miserably: it worked, but result was less than acceptable.
This was probably due to hair type: I used cones for fast results, but
looking Your picture, I realize that something more sophisticated works
much better. Now I know, what PovRay means: Persistence of Ray tracer
(in order to get good results). Unfortunately persistence is the very
thing, which seems to miss in my case :-( (in addition to time).
This approach (creating many, many objects) seems to give better results
in some cases than media: it will probably render faster and result is
more realistic. There was teddy bear, whose fur looked better than
anything before seen for hobbist range, but realism still lacked. I
tried to create hairs, using media, but again, I had not enough
persistence and result was not good.
