Hi All
I've had to learn so much to make this picture but before I say more, I'd
like to explain the picture.
There is a deserted village on an N.Wales beach that can't be reached by
road. I discovered it many years ago, in my rock climbing days, whilst
looking for new crags to climb on. It is on a beach of huge egg shaped
stones. On this beach are the remains of a wrecked boat. On one of my visits
I found a rock delicately poised on a tangle of rusted beams. I made several
drawings but never got round to painting it. Whilst looking through my
sketchbooks for something to inspire an entry for the worship round of the
IRTC I came across one of those drawings.
This was originally intended as an entry but it's far too obscure, off topic
and I haven't managed to get the gulls posed expressively enough.
The gulls were modelled in Hamapatch and UV mapped with the help of UV
mapper and Thomas Baier's excellent 3Dwin4. I've since managed to discover
how the wings actually fold onto the back but so far haven't been able to
improve on them.
The rusty girder was made from extruded splines modelled in anim8or, a
brilliant and free 3ds modeller. The model was imported into ppmodeller and
the mesh distorted and subdivided. The eggs and rocks were made in a similar
way.
This is the first time I've really had a go at using radiosity in an outdoor
scene. The settings are fairly standard. I had to play with diffuse and
ambient to get the right balance of tone and radiosity. One light was used
for the sea, there are two discs either side of the egg one very bright pale
yellow (ambient 10) and one dark purple one for the shadows (ambient.1). One
of the problems with radiosity in an outdoor scene is that the skysphere
colour dominates the colour of the scene, so I added the two disc to create
highlights and shadows.

It's a really nifty image. :{)
The shadows, however, are a bit too bright and soft given the overall
lighting in the scene. With such a bright clear sky, you'd get fairly strong
shadows, and noticeable darkening underneath objects. I'd suggest playing
around with "finish {brilliance}". Beef it up to maybe 1.7. The shaodws on
teh cradle are actually lookig pretty good. It's on the smaller objects like
the birds, the small stones, etc.. where the shadows need work.

IS this a fairly accurate image of the original scene? In other words,
was it just a coincidental placement of the rock in the cradle? That's very
cool to have found that in real life.

That looks nice, enter it anyway. Your birds look a little too smooth, and
maybe your sky could use something to look at... clouds/airplane/alien
spaceship/more seagulls.

This is one of the problems of using rad it provides a very general
lighting, I'll try brilliance. The final picture will have clouds in the sky
which would soften the pictures. Problems is the clouds bump render time
from 9 hrs to about 5 days.

Another problem with rad it destroys normal textures I agree with you
though - it's on the to do list.

No it's purely a fantasy based on playing with what I saw. My first reaction
many years ago was that it looked like a giant egg cup. The notion that the
gulls might "worship" a giant egg occured when I was looking for an IRTC
theme.

This is an interesting piece. Looks like you have that rust worked out pretty
good.
I agree about radiosity. The lighting should be harsher, more contrast,
especially eith no clouds.

Yes, and the wing of the one in flight look strangely flexible. But you
still have 33 days to go :)

It would be nice if object could be excluded from radiosity, or maybe
better if it could have an other colour for the radiosity calculation than
its real colour.
For the skysphere, maybe start with a white sphere, stop the rendering
after the pre-trace, save the data, start the render again with a blue
sphere. Again stop/pause it after the pre-trace, delete the radiosity data
and put in the saved data. Havn't tried it, so no idea wether it works or
gives the desired result.

I love it!
But... (Always a but)
It looks like your birds have an ambient-setting above 0. Replace it with
ambient 0, and it will look even better.
