Hello Everyone,

     I'm back again.. Got a quick question, is there a way to Warp text?

    I Want to take a string of text I Created with the
text {} tag, and want it to go around a cylinder..

As I have it now, a part of the text, "hangs" off the edge of the cylinder..

Anyone got any suggestions?

Much appreciated..
Dave

If the text doesn't have to be a 3D object but it suffices to be a pigment
on the surface of the cylinder, then make an object pattern from the text
and apply the cylindrical warp to it and then use it as pigment on a cylinder.

Not that I understand cylindrical warps (never used 'em), but you might be able
to make it 3d using this technique.

Use two nested cylinders, use the object pattern on the outer one, using a
transparent pigment for the non-object areas. Your letters would then be 3d
IMHO.

What? No!

The surface of an object never changes no matter what textures you use.
What you suggest would produce some curved 2d letters floating around
the inner cylinder, but without being 3d.

If the shapes of objects depended on their textures, we wouldn't need
isosurfaces! ;)

Of course I may have misunderstood you. But those letters just won't be
3d... :/

Sounds right to me - what was I thinking of? Another beautiful theory slain by
an ugly fact.

Warp,

    Thanks for the info.. that seemed to work, without the Warp.. :)

    But I have a Word like: Text, the Top of the Uppercase word is clipped,
but the rest is okay.. is there a bounding box for this?  Or do you think I
have to try and rotate it a little?

Hard to say without seeing the code, but it sounds as though you need to to
make your text-depth bigger. I suspect that what is happening is that your
text doesn't intersect the cylinder at its upper and lower bounds.

If I understand the principle of warps correctly, Warp's warp would avoid
this (and the distortion of the letters).

I think my text intersects.. I can make it deeper I guess..

** Note **
I forgot to send this, but I did try the depth and that worked WONDERS..
thanks alot eveyrone!  This one will be posted here (p.b.i) when I get it
finished.. :)
