There is the latest WIP for my apples scene. I've placed the basket and
also some other background objects.
The barrel is my old model, but translated to an isosurface for the real
woodgrain (still very wip). The red thing at the right tries to be a
courtain, but the isosurface is not very semblant to a cloth.
The area lights are off for this test, and the rad settings (loaded from
another scene with similar but simpler shapes and textures), are not very
high-quality. The focal blur settings are also poor. But render time is
scary: 7h for 512x384! I think the final render will take a few days...
Coments and critism expected, as usual...

Yeah, just what this scene needs to never end... :(
I'm thinking on alternatives to the isosurfaces used for the courtain and
the barrel, because the extreme render time is stoping me from adding more
features.

You can always post formulas of it here. Perhaps some tricks could be used to
simplify calculations.

Hmmm... it's just :
function{f_sphere(x,y,z,1)+f_granite(x*10,y*.01,z*10)*.005}
for a "base" isosurface from where I take several sections for the curved
boards. Do you think it can be enhanced? It's not really that slow, but
added to the other slow techniques I used, it increases the render time
notabily. Anyhow, I don't have any other idea on how to do it, and it looks
very nice and realistic... WIP 5 soon!

Have you experimented with HF_Sphere macro from shapes.inc ?
You can modify it to drop all triangles where all three vertices are outside
section you choosed. Creation with necessary accuracy can take some time but
created once it can be quickly reused in every next render.

Thanks! This must be the best solution, I think. I was trying to do it
directly with a height_field created internally with the function image
type, but I was having many problems to obtain the right curvature.
I was not aware of this macro. I'm reading the docs, but really slowly,
and not arrived yet to the includes: thanks again!

I managed to make a derivative macro which generates only 1/4 of a
sphere, cutting from it (randomly) the curved boards. The mesh file only
takes 6MB and was generated quickly. Thanks to you and Rune for this great
macro! Also, your suggestion to use it was really clever and "ready to
use": wow!
I've attached the result: it needs still some work on the "wooden"
function for the mesh, but it's promissing.
