I'm making a paint can and I want to put a logo on it.  The current
image can be found at:
http://www.cs.purdue.edu/homes/larsonpg/paint-can.jpg
I have one cylinder with a metallic texture, and another with an
orange-striped texture (a la Porter Paints), which is the paper label.
Now the logo is simply a rectangle that will be on the label.  Does
anyone have a way of getting that logo on the label, aside from just
putting the logo on the texture itself and mapping that?

Thanks,
Paul

Look in the docs for information about the image_map pigment.  You will
use this pigment (choose the appropriate type to get cylindrical mapping)
in the texture for the label.

This sounds like another candidate for the VFAQ.

Nathan,

I'm already using the image_map pigment on this image.  If you look at the
image (http://www.cs.purdue.edu/homes/larsonpg/paint-can.jpg), you'll see
the orange-stripe texture.  That is an image_map with cylindrical mapping.
My question is, how could I get a rectangular logo on the paint can?  Could
I make another cylinder around the can and map the texture on that?  I tried
that but I had trouble scaling and rotating it.  The other option would
simply be placing the logo on the orange-stripe texture itself, I suppose.
Did any of this make sense? =)

Let me see if I understand. You want to put a logo on top of the texture that is
already cylindrically mapped on the can? If this is the case, then you need to
make sure that the image you paste on top has transparency, then you just make
the texture like this:

texture C {texture {A} texture {B}}

And B will be on top of A. It's just that simple... That's how I got the rust
stains on the deck plate in my hallway image.

Oops, sorry. Please ignore texture C. I meant to #declare texture C as
texture {texture {A} texture {B}}, OK? I hope that sounds right...

If the stripes are an image map, then yes, adding the logo to the image
with the stripes will be the easiest method.

Since cylinder image maps aren't that flexible, you would have to place
the label in a very wide canvas (aspect ratio of pi or 2 pi, I beleive)
with lots of space around it on all sides, and create an alpha channel
with that extra space black. then it can be placed.
I'd just add the original images together to make it simple.

On a  more complicated scene, I threw a label on a beer bottle:
