Ikea's cheap furniture look very Povray friendly with their simple 
geometric shapes.  I just bought Ikea's cheapest sofa, the Klippan.  For no 
good reason I took a ruler to it and modelled it, all primitives and CSG.  
Not quite finished.  The back still has some unsightly protruding geometry.  
And the most difficult of all is that the surface looks way too perfectly 
streched.  I need a way to add creases in the cloth consistent with the way 
it's tucked in.  I've tried a bunch of procedural textures and I just can't 
get it looking right.  I'm actually thinking that I need to use SimCloth on 
the individual pieces, but that's probably overkill.

i think simcloth will do the job very well indeed.

Now I know why I modelled it...  I just need to model the rest of my 
furniture so that I can start doing some interior decorating... not!

Spent a few hours on the Klippan sofa last night and this morning before 
and during the F1 qualifications (GMT-5 here).  A lot of time for a simple 
object.  The room is very simple, used a photo from the window, easier than 
modelling the window and the outside ;-).

I suppose you mean, the irregularities are missing. You can add them without
changing the model a lot. Once, I did the following: Changed the cylinder
primitives to using a cylinder macro, that makes an irregular cylinder. It's
not going to mix perfectly with the boxes, but it will be what it's supposed
to be: Imperfect and random... Something like:

#declare Irregularity = .075;
#declare Steps = 10;

// First the usual parameters of a cylinder, then the extra stuff
ir_cylinder ( -1*y,  1*y, .5,   Irregularity, Steps )

This will add some noise to the edges of the object, and that might be
enough to make a bumpy texture convincing.

Regards,
Hugo

But does that have anything to do with my comment? :o)
