Well, I'm not sure what you mean with texture "cheat". There ARE 4 speakers
behind the grille and they are visible only through the meshes. But I did
not
create the cloth weave by using 200.000 torus differences. (Indeed I have
tried
this first but it was VERY slow and required so much memory.)
Soon I'll post a short tutorial to povray.text.tutorials to explain it.

Nope.
(Indeed I still know nothing about isosurfaces

Try it - it's very simple!
Some mesh is created this way:
#include "functions.inc"
isosurface {
function { f_mesh1(x,y,z,0.05,0.02,1,0.01,1) )
}
contained_by { box {-1,1 } // container shape (way to big in the
y-direction - too lazy to type more)
threshold 0.02
pigment {rgb 0.5}
}
You'll have to adjust those 5 parameters, as I copied them out of one of my
scenes (definitely no speaker grid). And you would have code that fold
somehow (should be not to hard by substituting the y and z parameters by
some math.
Not that I'm saying isosurfaces are the answer to everything - your grid
looks very good the way it is. But there are many people who seem to fear
isosurfaces as something complicated.

Marc-Hendrik

I like the leather effect and the way you have moved the piping around
the joints. I would be very happy if that was my pic. I can't find
what you think is wrong though.
Height fields are not so bad. They are faster than isosurfaces for me
and don't give you headaches with the maths ;-)
My pic was meant to be used as a base for a glass ornament but I
didn't like the way it appeared through the glass. I think it needed
around 10MB mem but render time was only around 5 mins.

Thanks a lot for this short tutorial. This gave me the final kick to start
playing with isosurfaces.

Hey, this woven carpet looks great.
Is the heightfield for one pattern and then repeated?
I do think so 'cause it is as perfect as my marshall
grille and that is a little bit too perfect. I still would
like to disturbe the weave a little bit.

Yes, that tile used 8*8 strands. If you want to play here is a 2*2
strand, 100*100 pixel tile.

Yes, I agree, perfection is not always good :) but... I have two old
heavy speaker cabinets, 20*40" / 0.5*1m, and the weave IS still
perfect.

I can only see two things wrong -
1. No guitar
2. Master volume not set to 11 (it's one louder...)
so what is wrong? I checked some photos and they seem spot on

Just in case anybody is still interested:
1. The Marshall logo in the late 60ies and
early 70ies did have a different shape and
was gold painted on the front. But it was
made from such a kind of material that it
easily did break. So almost any amp from
this time has either no logo at all or the logo
was replaced with the newer one. And so
did the guy from whom I bought the amp
about 12 years ago.
2. The original cloth weave in front of the
speakers did look different. I have destroyd
the original one during a concert (by accident,
I swear) and have replaced it. The image
shows the new one.
3. Because I was stupid or maybe only tired
I did fail in calculate 12 inch to cm. (One
POV-unit in the image equals one cm). So the
speaker cabinet as shown in the image is the
only one in the world with four 10' instead
of 12' speakers. I did realize this after the
6h render was finished.
keep on rockin'

Well. Yes. You are right. Especially with the master volume.
This two points can also be seen as errors in the image.
So I have done 5 mistakes in one single image. Unbelievable.
