For some reason, whenever I render this scene, it looks kind of crappy.

#include "colors.inc"
#include "math.inc"

camera {
  location <5,5,-5>
  look_at <1,0,-1>
}

light_source {
  <5,5,-5>
  color rgb 1
}

difference {
  cylinder {
    <-2,0,0>,<2,0,0>, 2
    pigment {color rgb 1.5}
  }
  cylinder {
    <-3,0,0>,<3,0,0>,.8
    pigment { Gold }
  }
}

difference {
  cylinder {
    <-2,0,0>,<2,0,0>, .8
    pigment { Gold}
  }
  cylinder {
    <-3,0,0>,<3,0,0>,.7
    pigment { Gold }
  }
}

#declare lv = 0;
mesh {
  #while (lv <= 45)
  triangle { < -2,sind(-lv)*4,cosd(-lv)*4 >,< 2,sind(-lv)*4,cosd(-lv)*4
>,< -2,sind(-lv+1)*4,cosd(-lv+1)*4 > }
  triangle { < 2,sind(-lv+1)*4,cosd(-lv+1)*4 >,< 2,sind(-lv)*4,cosd(-lv)*4
>,< -2,sind(-lv+1)*4,cosd(-lv+1)*4 > }
  #declare lv = lv + 1;
  #end
  pigment { rgb 1.5 }
  translate <0,0,-6>
}

PS.  Sorry for the bad pun.

Well, you're only using pigments to describe your object. Maybe you should
add full texture descriptions (like finish and normals) to them. Also, gold
is probably not the best color for the inside of the roll; it's too bright.
Try a dark brown/gray.

But, the shape of the roll looks great!

I think it would still look "crappy" after that. ;-)

Nice design...

Reminds me of a Bin Laden joke someone sent me with bad texture mapping.
Needs some UV Mapping perhaps?

Well, when I used Brown, it actually appeared more of a dark red than a
brown.

Also, I'll probably replace the mesh with a hollow cylinder CSG'ed with a
box.  It'd probably be a bit faster.

As for textures, I suppose I could make a texture to give it the quilted
look.

Yes, "brown" is not really brown... try one of the ones with "wood" in
the name.
