Hi,
Can someone tell me what UV-mapping is?

It is a way of applying a texture to an object in such a way that points
on the texture will be mapped onto the object at similar parametric
coordinates. For example, let's say the bottom left is (u,v) = (0,0) and
top right is (u,v) = (1,1), and we map that over a bicubic_patch, the
(u,v) of the texture will follow the (u,v) of the patch, and be deformed
with it.
See p.b.i for example image :-)

So, it isn't anything more than an intelligent imagemap?
Thanks for the explaining and the example,

That's exactly what it is...though it isn't restricted to image_maps.
It's just a way to manually specify how to map the texture onto the
object.

It was? Well, it isn't any more...I had to reset my signature because of
a power failure(the change apparently wasn't saved to the disk), and the
fish faces left now. :-)
