Here is how I spent my weekend. Maybe the mouse could use it :)
It is just a Win MPOV 0.7 motion_blur object with a very high
sample_count in the global settings, some scaling, translation,
and some clock-dependant, noise-modified, rotation.
The most difficult part has
been understanding precisely how motion_blur distributes the
samples, in order to gain some control over effect. I'm posting
the scene-file to p.b.s in case anyone's interested.

I can think of large variety of ways to spend a weekend worse... That

At least I am.

My first thought - Wow! A furry thing. Just what I needed. I've been
trying brown grass!!
My second - Does he mean my mouse?
I've only used MegaPov for photons so far. About time I looked into it
further.
The trouble with tribbles is that no one has seen one (?) but the
advantage is that no-one can contradict your post ;-)

Thanks!
Yes. I was talking about that cool mouse you built. :) Might be kinda tricky
around the helmet, but I'd love to see what kind of results you get.
My only objection to the technique is that while its nice and wavy through
most of the hair, its just too straight on the ends.
I was thinking about experimenting with the pcm.mcr morphing macros: feeding
the macro's mclock variable a loop counter instead of real clock values, and
possibly jitter_mesh to gain some control over this. You wouldn't
necessarily have to have MPOV for that, but you would have to be careful
with the transmit values in your pigment statements. I think the motion_blur
patch was designed to simplify this part of things.
Thanks again. :)

I've had a routine for hairs, bristles and spines for a few years but
its only usefull for spheres, cones and cylinders. I don't know how to
find the surface of a superellipsoid or blob. I could difference the
mouse body from a union of hairs but the hairs' _lay_ looks very bad.
This is a shell of 30K hairs over a hemisphere.

Hey! I think I've seen this thing before. Only the eyes weren't quite that
creepy last time. :D
That's good looking hair too. Maybe MPOV's trace functions could help.
Judging from some of their animations, Rune and Greg M. Johnson could
probably tell you how to find the surface of just about anything.
Are those 30K hairs meshes, cylinders, cones, or what?

It started life as a hedgehog (Porcupine for non-euros ? ;)- a simple
cone+sphere job long time ago. Probly must have uploaded it somewhere
at some time.

Yes, mpov's trace would be useful but I prefer to damage my grey
matter with official pov, never seem to get the time to explore mpov
:(

#declare Hair = // cone{ 0, 0.04, x*1, 0 // Alternative
union{ triangle{ <0,0,-0.02>, <1,0,0>, <0,0,0.02> }
triangle{ <0,-0.02,0>, <1,0,0>, <0,0.02,0> }
}
// With this complicated texture:
pigment{ rgb <0.2,0.1,0.05> } finish{ diffuse 0.8 }
Will clean and post source to p.t.s-f, FurThing in p.b.i
