Yes, 'tis Aiko! Silly really, I end up using her for everything at the
moment. The main reason is that I'm only really interested in using Poser
figures to establish scale, and for a touch of the 'human presence'. I've
found good quality free body textures and hair for Aiko so I've stuck with
her for the time being.
Yah, the sand issue. Actually sand *can* look totally flat and textureless
under some conditions, but I agree it does lack a little something. On the
other hand, you recognised that it was sand quite readily! ;-)
I am continuing my experiments with a low-level view of the sphere.

If you pose her pushing that column (the column on the floor in front
of her) into the sphere, then that would finish this image for me.
8/10 :)

You know, I think the only reason I mentioned the sand is that the
texture on the blocks is so nice. :-) It makes the sand stand out as
bland. :-P
BTW, it would be cool to see this image with radiosity. Bring it up the
level of your 3D-rtc entry. ;-)

You know you've been raytracing too long when you've ever "lost" a Julia
fractal because you're not quite sure how to align things in four
dimensions.

Interesting... Like it!

The blocks have only basic grey single-colour pigments. The texture comes
from their physical shape :P . In the close-up version (rendering as I
type) I've given the sand some turbulence so it looks grittier. It's much
better.

Errr, this image already relies heavily on radiosity... without radiosity
the shadowed areas are all black.

Wow, on the first take it sure looked like just ambient to me, but I'm
starting to see the radiosity effects on the inside of the sphere.
Are you using any sort of sky sphere?

You know you've been raytracing too long when you know what each part in
a motor looks like but don't know its name.

Yep, a big blue one! :-)
Actually, it's just a background { rgb <0.7,0.9,1> } but MegaPOV seems to
use the background in radiosity calculations by default.

Acording to my experience, POV-Ray normaly use the background, and any
background feature like a sky_sphere, when evaluating radiosity.
Look at the attached image from a short code contest. The sky is background{rgb
<.5,.7,1>}, the light <8,4,2> and the ground rgb 1 using radiosity with default
settings. You do see bluish areas.

Ah, interesting, I wonder how I missed that. Something I've done in the past
definitely gave me the impression that POV-Ray ignores sky_sphere and
background in radiosity calculations... thanks for the pointer. :-)
