Just modelled this basket today for my apples scene. I was fearing a
complicated modelling task, involving sphere_sweeps and obscure trig, but
suddenly I figured how to fake it only with tori (well, and some
cylinders... ;). There are about 1300 torus sections, placed with loops.
The basket wall was easy, but the top and bottom parts come out by pure
trial&error, I must confess...

nice :)
this is realy complex object imho
I must do to something like this someday, I'm woundering how it will be
easy (or hard) using isosurface

Nice ! I think there's one on Chris Colefax's site and I have one by Fabien
Mosen that fits a bottle.
Perhaps we should start a collection of wickerpov objects... Interestingly,
this is the sort of object that is pov only and that really demonstrate the
power of scripting, as it would be very difficult to do it in a GUI/mesh
modeller.
Interesting background too... Are you using your light macros, btw ?

Beautiful! Zubaran?
When I tried a similar technique, to make the rattan background for my
"Spirit of Asia" entry, the render time became unmanageable.

not every one - I'm still writting my isosurface optimization test scene :)

I must admit that was my first tought, but my apples scene is slow enough
without isos.. :)

Yes, I remember these now. The one from Fabien is really nice, if I
remember well.
> Interesting background too...
It's a very thin height_field with a standard stone texture scaled down
on the HF height direction. This way the HF shows different parts of the
texture depending on the height, sowhing very interesting patterns. The
wood uses the same trick.
> Are you using your light macros, btw ?
Always. I can't remember when I worte my last "light_source" sentence
directly... :) Seriously, it is very handy for me, mainly because I can
adjust the overall lighting with two control variables.
