How to make a "barrel" shape from a flat image (?)


Question

If you have a flat image ie logo you want glue onto a cylindrical "package" to show final product -- what free s/w package (or script) do you use?

(I use inkscape and gimp to create flat art with no real knowledge of 3D editing except perspective in gimp)

If you are starting from an image, and you must insert the label, I suggest you to use the GIMP.

A. Suggested method with the GIMP

A very simple way to "glue" your label onto a cylindrical package is shown here (not my work):

B. Have some fun with the GIMP

Alternatively, you can generate the cylinder using the GIMP's built-in Map Object plug-in, which provides a way to project an image on a cylindrical surface.

The start image will be mapped on the lateral surface of the cylinder, and I've seen that is better start from a square image (either, you need to resize the resulting image), for example:

start image

If you need to show the top or the bottom of the cylinder, you should also provide something like this:

top image

Now, you can invoke the filter: Filter -> Map -> Map Object...

the filter

The filter has some options:

The final image:

final image

You can also start with an image with an alpha background:

final image alpha

So... have fun with the GIMP!

have fun!

C. Alternatives with the GIMP

There are obviously a lot of alternatives, like the Panorama Tools Plugins. It could be a little tricky to use, but is very interesting.
