I do not know whether the description in the subject line defines well enough the problem but that’s basically what i am after.

I want to work on some pictures to show them as if they had been placed on a thick canvas like support of let’s say 1" inch thick.

Are there special plug in to accomplish that?

Thanks

An easy way is Filter>Texture>Texturizer.

Thank you for your answer but I am afraid I was not very clear.

What I am after is to have an image taken from the side and giving a perspective as if the image was on a thick board, that is to say, showing two sides, elevated from the plane on which the picture normall is.

In other words a 3D instead of 2D.

Try Filter>Render>3D transform, then.

if you have cs, you need to load the 3d transform plug in from the goodies folder on the cd first though.

Thanks to both Mathias and Dave,

I have photoshop 5.5 and I did find the 3D Transform under Render but nothing seems to happen whatever I choose as angle or object.

Is there anything special to do (like do I need another layer?) if i am loading a jpeg image? (Does this work only on some picture formats?)

Serge,

I’ve not used the 3D Transform filter before, but a quick look at it suggests that it should work on any normal RGB or Grayscale mode image, as well as other modes perhaps. The image file format, particularly if JPEG, BMP, TIFF, or PSD, is not likely a factor in why the filter doesn’t appear to work for you. I’m guessing it may just be unfamiliarity with how the filter works, as my first application of it seemed to have no effect.

That is, in a quick example, I opened an image and then with the 3D Transform dialog shown, I selected the cube tool and placed a cube wireframe on the image and applied the filter. The result was not what I anticipated, as I was guessing that perhaps the image would be manipulated as if the image was folded on the edges of the cube. So, proceeding to "play" some, I combined use of the other tools to rotate and change the perspective of the cube some, and began to get a better feel for what was going on. I’m guessing you may not have tried using the various tools to modify the wireframes as is needed to obtain more pronounced transforms. It does not appear that the image has to be layered or even promoted to a floating layer…a flat image would still be modified from what I saw.

Given that Mathias suggested the 3D Transform and is a quite knowledgeable user of PS, I suspect it should be able to handle the task. Otherwise, I’m wondering if perhaps just a perspective transform might be a better approach? Maybe the 3D Transform would accomplish the same thing yet wrap the image around an edge, as one might stretch an art canvas around a stretcher frame so that the painted canvas also appears on the edges?

Regards,

The 3D transform filter is not very easy to use, but it should accomplish the task. Draw a box over the image, then use the Direct Selection Tool on a corner to set the depth of it. Then use the rotate tool to put it into perspective.

Personally, Iยดd prefer a 3D program to do this.

Thanks again to both Mathias and Daryl,

I will experiment but I’ll be away this week end.

Many Thanks

Hi Mathias,

Well, I’ve been playing around even more…always fun to explore something I’m clueless about. I think your last comment is the best answer for this. For what I can tell, getting the closest result to what may be desired requires really learning how to manipulate the handles of the wireframe. Since not all vertices can be moved around, that also complicates things some. But, perhaps that’s how wireframes are normally manipulated.

I also wondered if the displacement filter might be used in such a case as this, but that’s yet another filter I’m not familiar with. Always something more to learn. ๐Ÿ™‚

Hi Daryl,

All one need to do is use the Direct Selection Tool with the lower right corner to set depth, then rotate the box to the desired angle. It doesnt offer very precise control, but again, should accomplish the task.

No, the Displace filter cannot skew perspective in the way desired. It works more in a ‘bumpmap’ way. Iยดve written an introduction to that filter here: <http://www.2morrow.dk/75ppi/3dtext/>

Where it says you need KPT3, you dont, anymore. (Sorry cant change it, no access to the server any more). From PS7+, just use Layer Effects Stroke, Fill Type: Gradient, Style: Shape Burst instead of KPT3.

Its a long piece, I know ๐Ÿ™‚

Mathias,

Your simple explanation is pretty much what I had tried, but never quite getting the sort of box rotation I was aiming for, much less having as much of the original image mapped onto the box as I’d have wanted. Still, I do agree that the 3D Transform appears to come closest to the desired goal as long as one must stick with PS.

As for your carved text tutorial involving use of displacement maps, it’s a good piece that I’ve yet to ever try and go through. Perhaps I will someday. I’ve got KPT3, so no concern there.

Thanks,

Daryl

As far as encompassing the whole image, one can enlarge the canvas a bit before running 3D transform filter. I dont use this filter much either, so I dont have a lot more tricks handy ๐Ÿ™‚
