  That library scene is getting really nice. I've a similar but smaller 
project, but it is stalled right now... Anyhow, I had the same problem with 
the colors of randomly textured books, and finally only found a solution: 
use random amounts of gray to dirt up the colors. I'm considering also to 
make some searchs on the net for images of book spines: I'm not very 
comfortable using image_maps, but sometimes they are the right solution.

I finally used gamut-constrained random colors. It looks more like
a classical library, but it looks nothing like my own library where
books appear to be of random colors.

But the problem is when you have, say, 100 000 books, you can't
possibly have images maps for each of them. Even simple books
composed of a handful of primitives lead you to a 128 M scene.
Which is borderline for my computer :/ I thought of replacing far
away books with only a squashed cylinder + box, but it's not quite
as nice.

Best,

  Hmmm... 100,000 books? That's a BIG library! :)

  I was not talking to texture each with a diferent image_map! I think that 
it can work only with a few, distributed randomly. On the attached test 
there are only 8 different image_maps, and they are really little jpg 
files. These are "bare bones" books, only a box and a squashed cilinder, 
but for distant shelves it works well.

those are awesome looking! You could easily adapt that technique to  making
volume sets too. I like and I might try something similar later when I get
the time :)

There are something like 70 000 books in the scene.

No, of course not!

...but doesn't pov create a copy of the texture by object ? How
much memory does that take for that small scene?

Btw: it does give a very nice result!

  + With 8 diferent jpgs, used as image and bump maps -> 2,350,847 bytes
  + With simple textures (solid pigments)             -> 1,048,211 bytes

  I will do some test later to see how it increases with the number of 
books...
