Hi-Ho

My latest project is a wastepaper basket. It looks already suprising cool,
but some really important part of it still lacks: The content.

I have really no idea how to make strongly crumpled paper, and I guess it
wouldnt be funny to stick meshes together. Is there a more intelligent way
to fill my wastepaper basket?

thx,
Brain

I don't see how it could be humorous or not, but it certainly wouldn't 
be an enjoyable experience. Short of some kind of mass-spring sheet 
simulation (like some variant of the cloth patch), a mesh seems like the 
best option. If you won't see it too closely, you could just ignore 
things like self-intersections. You might even be able to get away with 
a crackle-sphere isosurface if it is only visible from a distance. A 
ball of paper is a complex object resulting from many different physical 
interactions, both in the paper itself and in the hands that crumpled 
it. Describing it is definitely going to be difficult.

Look at the cbwar.jpg picture here

I guess that the macro is in the zip (not tested)

Well, this basket is my first serious povray-Project. And I'm sure you know
how impatient we noobs are :) So I'll try first to have maximum success with
as less as possible work.

Hmm, I guess this is what I need. But I am not sure how to use this Macro,
because the comments are written in a... whimsically language ;) Thanks.
