using 2 blobs (a blob and a "shell-blob") and 2 'fur'-shaders...
Parse Time: 0 seconds
Trace Time: 1 hour 41 minutes 12 seconds
Peak Memory Used: 168768 bytes (164.8 KB)
Pentium 3 450Mhz, 192MB RAM, under Windows XP, GUI priority: highest, Render priority:
lowest.
Rendered in POVMan 0.71.4
The shader for the "shell"-object could be used as only shader (so you don't need
another
object) for far away objects, but you could see the background through it at places
where
you shouldn't... (that's why I needed a solid object underneath it)
Fortunately, making a "shell"-object is very easy to do when your using blobs.

Wow .. it looks like 'matted fur' but it's still a great effect.

Strange, I was just thinking about ways to render fur earlier today. This looks
pretty good. Might look better if it was combined with the anisotropic shader
though. Or, at least some way to get the highlights of the individual hairs
brighter on the parts of the object more perpendicular to the camera.
BTW how did you do that background? I really like it.

good idea, I'll try that tomorrow!

shading more or less as in Rune's fur-texture, and for the shell-object a transparancy
based on the x-ray-shader included with POVMan: transparant at the edges, opaque
elsewhere.
goodnight!

Beautiful!
Can you tell how the fur was created? I've heard the term "shader"
before, but not sure what that means in this case.
Thanks,

simply put, a shader is a formula that tells the renderer (in this case POVMan) how to
color (or "shade") a point of an object. If you want a more detailed explanation,
download POVMan and read the documentation, then read part II of The RenderMan
Interface
Specification
(http://www.pixar.com/renderman/developers_corner/rispec/rispec_3_1/index.html)
good night!

Looks "crappy"! ;-)
Very nice, all in all...

This doesn't look like fur to me, but does make it look as if the image has
been painted with some kind of oil brush.
Beautiful effect, and actually much nicer than fur. I'd love to see a real
scene done like this.
