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.

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.

Being usually very bad at making effcient CSG, I was surprised this one
only took 2 minutes to render... Well, now that I think of it, there is not
any "difference" on this CSG... ;)

I don't want to know what you are doing in a house that is not yours, at
such hours when everyone is sleeping... must be some YKYBRTL, sure. ;)

The texturing looks perfect. Has it got a bottom in it?

Hmmmm... uh.... eh.... no. :)
It also needs a good pair of handles... I'm working on it, but you know,
wickerwork is slow....

I was just kidding here. I don't think you invested your sould in order to
achieve this all. But I bet you invested quite some time. And your computer
did the same with his cpu time I guess

He's obviously broken in to steal their CPU cycles for a render :)

Installing POV-Ray on my g/f's computer was a really hard test for our
relationship - but what can I do, I have a 400 MHz K6 and she has a
750 MHz Duron. The lure is irresistible :)

I'm in Estella (Navarra, a city close too Pamplona) with all the family and
some friends.
We are now on Fiestas (similar to Sanfermines).
But you are right.... YKYBRTL when you are reading the newsgroups at 4:00
a.m. and still you don't wanna sleep.
Anyway, have you thought about putting handles in the basket? I think it'll
improve the model.
Great wall and lightning also.
Waiting to see the final composition.
Bye

Search p.b.s-f or p.t.s-f for his (Jaime's) light macros.

It's the best kept secret of Povdom... Jaime has designed macros that
simulate real artificial lights such as incandescent or fluorescent ones,
based on physical data. They're available at his website

Yes, I'm just waiting for more whicker... I've expended most of it with
test renders. ;)

It's almost ready. I'm adding an old barrel also and some other little
details. It will be posted here next week (it will need at least 2/3 days
to render at 800x600, I think).

Newbie here, this looks like a water mouthing recipe, but I don't have a
clue on how to get the ingredients...
Would you mind to translate this in real code, so we can try and experiment?
Thank you.

Sure! Here it is an example image attached. The code for it is at

To you also: this goes to my "tips&tricks" web page... on the next update.

Thanks a lot. I knew that I am color blind, but I was fearing to be totally
