I'll see if I can hunt it down, it might be on one of the other computers.

I don't see the original code for this example, but you might try something
like this as a starting point:

#declare length=1;
#declare base_width=0.05;
#declare tip_width=0.01;
#declare segments=50;
#declare base_curl=0;
#declare tip_curl=0;
#declare scraggle=0.75;
#declare scraggle_freq=20;
#declare save_name="scragglehair.inc"
#declare scraggle_seed=723562;
#declare tti=5;
SingleHair(length, base_width, tip_width, segments, base_curl, tip_curl,
scraggle, scraggle_freq, save_name, scraggle_seed, tti)

A quick render with these settings gave me the attached image.

Preview of image 'MayaFurDemo.jpg'

Looks like a dog who got a pretty serious electric shock!

I wonder though, if all these triangles are copies of one mesh because they
look very similar, in this image.

It's nice.. Probably the best fur macros I've ever seen for POV.. I'll hope
to use this somehow. :o)

After some tries, I think that improving memory use and rendering time 
could be a priority for the MayaFur.inc
I tried the example yesterday night and on my XP2800 with 1Go I fell 
down to 10PPS (Quality set to 1) !
Apart from that, the packaging of the include is really great with good 
explaination and schemas.

The thing to understand is that if you want a reasonable render time you
have to turn off TTI and use a standard POV texture.  It would help to turn
off (or at least tone down) the radiosity too.  That demo image uses pure
radiosity lighting and TTI texturing, which takes a lot of memory and
resources.

OK, I'll try to change the settings, maybe you should make your example 
auto-tunable, because it's a bit frightening at first.  :-)

Is it just me or are there "bald" patches in places on this image?

Post a reply to this message

Yes, but that's because I turned down the hairs_per_unit to a really low
number, since I was only testing scraggle.

Yeah, with the demo scene, I was trying to max out the settings on a low-end
machine... p3 700MHz with 256meg.  The fact that I could get 160,000 hairs
with pure radiosity lighting and triangle texture interpolation seemed
pretty good to me on that machine :P

Okay, thanks. I have to figure out hot to turn that into a more abstract
shape, but that should be a fun exercise.
Thanks again,.
