Titolo: deformare oggetto.

Ciao ragazzi...č la prima volta che posto qui.
Spero in voi visto che non riesco a trovare la soluzione a questo mio
problema.
Ho due immagini:
1 - raffigura un bel barattolo di vernice
2 - č un logo.
Dovrei incorporare il logo nel barattolo di vernice, quindi far prendere una
forma leggermente sferica al logo
cercando di rendere il tutto piů realistico possibile.
Confido in voi.
Grazie mille per l'aiuto
Mancio

 
la forma "sferica" è un'altra cosa cmq ho capito (almeno spero) cosa 
vuoi fare, questa domanda ritorna almeno una volta a settimana...
Ti ho fatto il copia e incolla...

 E' sbagliato o momentaneamente fuori uso?
ho provato ieri e dopo aver cancellato la cache, ho appena riprovato e 
funziona benissimo.

Labeling a Bottle
with the 3D Transform Filter
In this tutorial, you'll learn how to make lettering curve properly to 
fit onto a curved surface. This goes beyond the Warps you learned about 
for Type, and in fact, can be used for making any image curve as it 
would in 3D.
This tutorial was written for use with Photoshop CS, but it can be done 
with earlier PS and with Elements. The screenshots from step B to the 
end are done with Elements.
If you have an earlier version of PS or PS Elements, you don't have to 
hunt for your 3D Transform Filter, because it's already installed. Meet 
us down in Step B!
A. Install your 3D Transform Filter
1. We will begin with this search. Dig out your PS CS disks and find the 
one labeled "Resources and Extras." Insert this into your CD reader.
2. Find your Goodies folder. From there, surf to Photoshop CS > Optional 
Plug-Ins > Filters.... Opening the Filters folder should reveal two 
filters you don't have yet: 3D Transform.8BF and Texture Fill.8BF.
3. Open another copy of My Computer and set it beside the one where you 
have your CD's contents. In the 2nd My Computer, go to C: > Programs > 
Adobe CS > Photoshop > Plug-Ins.
4. Now drag the 3D Transform filter plugin over to your Filters folder. 
(You can drag the Texture Fill one, too, if you want.)
5. Close PS and then reopen it. NOW we're ready to proceed.
B. Bring the label to the bottle
Begin with a photo or drawing of a wine bottle and your label image on 
another layer or in another file.
You’ll need to have the label and the bottle in the same document, on 
different layers. To bring the label into the bottle file, you first 
make sure that both files are in RGB mode. (Image > Mode... RGB)
Choose the Move tool and, with both files open, drag the label from its 
canvas to the wine bottle's canvas.
C. 3D Transform the label
Filter > Render > 3D Transform. (The filter is now there! If it isn't, 
go back to step A.)
This brings up the 3D Transformation dialog box. Choose the Cylinder 
tool and drag a cylinder across the label, roughly resembling the width 
of the bottle.
D. Straighten the “bottle”
We now need to move this wire frame so that, if it were the bottle, the 
label would be straight. In other words, you'll move the wire frame so 
that it becomes a rectangle.
To do this, use the Direct Selection Tool (white arrow, see at right) 
and drag the bottom center point upward.
E. Move the bottle frame with the label
To move the frame with the label to make it shaped like the bottle, use 
the Trackball Tool. It is fun to drag this all around, to see what your 
label would look like in all positions.
Once you get it where you want it, click OK.
F. Cleanup
Now we need to clean up any extraneous bits. In my example, I have the 
gray circle at the top, and a little of the label to the right side.
Select these areas and hit the Delete key on the keyboard.
G. Tighten up the label
You may need to do a transformation to make the label fit precisely on 
the bottle.
Use Ctrl-T to bring up the transformation handles. Hold Ctrl to pull the 
corner handles if you need to distort the transformation, as I did here.
 
H. Shade the label
Add another layer above all the others. Put this layer into Linear Burn 
Blending Mode.
Ctrl-click the label layer to load it as a selection.
Then use your gradient tool (Reflected Gradient, white > black) to shade 
the label.
A tiny drop shadow can help to make this more real, as can a 
1-pixel-wide stripe of white above the label. You can do this by loading 
the label as a selection and filling this selection with white on a 
layer beneath the label layer. Then use the Move tool and the up arrow 
to scoot it up just one pixel.
