So, I've had some spare time and continued with the modelling of my "Sitting
Cat". It now features a tail, whiskers, and even a nice nose. :-)
The colors aren't final yet, I'm undecided if I want to go with this
color-theme, or if I'll switch to something more gray/brown/black-ish, it'll
probably depend on how the cat looks when placed inside the scene (which has
yet to be built...).
In case anyone's wondering, I've made excessive use of object-patterns,
trace(), pigment-functions and the like to composite and generate general
pattern for the cat, which I then color using a simple color_map. The nose
is actually taken off a photo and, using functions again to create a
transparency map of off the inverted grayscale image of the nose, the image
is placed onto a sphere and position where it is now. The whiskers are CSG
made with a simple macro.
I'm wondering if I'll add some sort of hair to the cat for a more furry and
chaotic look, but I want to focus on different parts of the image and leave
that detail for later. It wouldn't harm if the cat were as orderly as it is
now, but it would harm if other objects are missing in the final image! ;-)
Comments and suggestions, as always, appreciated!
Regards,
Tim

Like stm said, the eyes are a little off. I think they should be
smaller, too. Good color choice, though. :)
I also agree about the color/textures - it actually looks a bit fuzzy
the way it is! It would be interesting to try that SSS technique posted
here the other day as well. Overall very nice, tho.
The only thing that hits me a little strangely is the shape of the snout
in the face-on model. It looks a little too large. The real ones blend
in with the rest of the head and come to a bit more of a point (the nose
makes kind of a blunt point, rather than just the apex of the blob).
That might be difficult to do with blobs, tho, I don't know. In the side
models it looks right.
Great job overall! An excellent model.

I gave SSS a try when I was beginning with the texturing, and it's really
difficult to set up properly and get a good visual effect, especially with
the complicated shape of the blob. For now, SSS has been ruled out until I
have some more time to create a proper technique which gives guaranteed good
results, no matter the angle.

Yeah, head on the cat's face looks a little strange, but it's mostly
lighting, blob's limitations and the texturing (no actual fur) which spoil
that view. As the cat will be seen sideways, I think I'll leave it at that.
I've learned that it's often better to head for proper "final" results,
rather than focus on details that won't be visible. I can always refine
models and textures when I need them in a different setting.
> Great job overall! An excellent model.
Thank you! Quite some work involved to get a decent cat. :-)

Tim

actually, i think the side view is the most odd looking. the forehead looks
too round. I was only able to find this illustration, but it shows what i
mean if you look at the black cat on the right.

there is a little dip between the top of the head and the nose.
otherwise, it's looking very catlike.

Thanks. I'm still trying to improve it, little by little. You often need
comments and suggestions from various people, cause when you're working on
something for a long time, you get used to it and won't recognize the
mistakes anymore... Hence the WIP post every now and then. :-)

Ah, thanks for that comment. My reference pics are mostly front views, and I
have to go by what I "feel" to be a cat in some parts. I'll see what I can
do about that dip on the head and the eyes, it seems like that region is the
one most find less cat-like...

Tim

Hey Tim! This looks really good. I think you've done a
great job on the fur. The back legs seem to be missing
the paws. The eye shape seems a bit off. On my cats,
you can distinctly see their mouths. The ears look
a little too plastic and "attached" rather than part
of the head. The front legs look good but the paws
seem a little small to me. The tail looks a little bit
thin. The head might need to be a little flatter on
the top. The eyes might need to be set further into
the head. But still, a wonderful picture and quite an
accomplishment for blobs!

Thanks for all the suggestions Bob, I'll see what I can manage. For the rear
paws: they are missing on purpose. The cat will be sitting in the snow and
thus, neither front nor rear paws will be visible, which is why I didn't
spend too much detail there. The head is a very tricky part, and getting the
ears to look properly attached is near to impossible I think (they are made
of a mesh generated with my BSplines and my Mesh-Modifying-Macros). I do
want to work a little more on the head though. If I manage to get enough
time, I'll probably implement some sort of "Fur-Dropper", which will place
some textured polygons onto the cat to simulate a more hairy fur, and this
might hide some of the rather messy details... And the cat won't be featured
too large in the final image, which is why I don't need a photorealistic cat
(though I do strive for it :-), but something which will fit the final image
nicely.
That's also the reason why I'll be working on some other parts for now, as
I'm not yet sure if I can actually make it by the deadline (christmas).
Still, this friend of mine isn't so worried about getting it on time, we
always give us the presents once we have found *proper* presents, not just
something you've found and bought because you needed *something*. Last time,
she gave me her present in March or so... We have some strange and rare type
of friendship...
Regards,
Tim

I agree with Bob!
One other thing perhaps. The chest should be a little more elongated
vertically, shortening the frontlegs a bit in the process.
The mouth indeed should be more visible.

I'm babysitting a kitten for some friends this week and I noticed
something interesting about her fur that might be useful to you, if you
ever end up using a hair macro or something like that.
Her fur isn't really just one color. It begins at the skin as almost
whitish, then goes slightly darker (to a very light grey) out to within
about 1/4" of the end. The last quarter inch is dark grey. It also has a
nice sheen to it.
If the fur on your cat is sticking straight out perpendicular to the
surface, the effect won't be noticed. But it will be quite evident if
you add some wind or maybe just some bend or something. It gives it an
effect somewhat similar to the SSS "velvet" we saw not long ago.
I'm sure my tactile senses (ie touch..she has very soft fur) have
contributed to the effect of the fur overall, but the colors do look
very pretty. :)

Ah, thanks for that inside info. I doubt that I'll script a fur macro or
something similiar for this image, but it might be useful for later scenes.

I have two cats, and occasionally they get into a tiff. One will
sometimes drop a whisker as a result of the fight. It's like a hair, but
much thicker, and easier to get a grip on what is happening:
Actually, the hair is colored more like a wood pattern. The inside is
one color, the outside is a different color. As the hair grows, the
outer layers get rubbed off, exposing the differences in color. As the
portion of the hair gets older, the thinner it gets. For example, some
cats have what is known as a "smoke" color to their coat. They have a
thick layer of white, or beige around a central core of some other
darker color, therefore the ends look darker. It makes the roots look
lighter. (Not to be confused with himalayan types, or colorpoint types...)
