I don't think that was such a great tut. It looks like a simple outcome.

Are you getting the full 3D effect from the final image? I mean are you seeing 3D letters floating over the background in this image?

You think I put together a whole tutorial just to show users how to use Dents? :roll:

Go back to the original post and find where it says:

What is a stereogram/autostereogram?
An (auto)stereogram is an image which contains a hidden 3D image within it. Viewing the image in a certain way tricks the eyes into seeing the 3D image which appears to “pop out” of the orginal image.

Follow the links given to Wikipedia.

Try the different viewing techniques detailed in the first few pages of this thread. Several methods are listed.

I can never see these things! They're just a bit too...hard for me to see.
This is what I look like when I try to see these things: :shock:
:) just staring at my screen, looking dumb.

......@Yellowman: Yes you’re absolutely right about the colored image, the letters and the depth. Re Sig: Yes I had considered this: viewtopic.php?p=251582#p251582


Oh ..I don't know how I missed this before, I didn't see it,I can see EER in the image:

I remember that I created and posted a 3D image before using a different technique called (cross-eyed)but looks like was not easy for some to view it even with the explanation details,it was more complicated on 13 levels(called 3D flowers)

I clicked on the link and I think it is so AWESOME how you made that Yellowman! Do you have a tutorial to go with it?

..although I can't see the images :(

If you've tried the viewing tips detailed in this thread then that's about all I can suggest. You might try Googling "Magic Eye" and see if you find any help there.

A couple of times in the past I tried to figure out how to do these with PDN - gave up in the end, but great to now see the methodology.

Nice tutorial - I will definitely have some fun playing with this (BTW - Pyrochild's Random Shape Fill plugin is great for backgrounds):

Thanks

Beam us up! Fabulous stereogram. How many tiled strips did you use?

The image is 800x400, and I used 8 x 100px strips for the background. I then cut the 'image' into 10 x 80px pieces.
I've always loved these 'Magic Eye' pictures - probably because I have no problem seeing them and so many others do, lol.

I am currently working on one for my daughter, based on Twilight (go figure!). I am trying to work out if I can get multiple layers (i.e. one on top of another). My first effort was unsuccessful :( - I'm also trying to see if I can do a true 3D style one, you know, like a shaded 3D texture map image - any ideas?

I suppose that kind of thing would require a sophisticated program, and do it 1 pixel strip at a time, each at different focal distances.

Anyway, I am happy with my first results and will still use this method in the future.

I suppose that kind of thing would require a sophisticated program, and do it 1 pixel strip at a time, each at different focal distances.

The problem is that we have to snap the elements to integer pixels when we really need to be able to subdivide them.

E.G. Imagine a playing card tilted away from us so that the left hand side is further away from the viewer than the right. In a perfect world, every 1pixel vertical strip should be moved slightly more/less than the last to get a truly graduated effect from left to right.

I'm sure that tiling vertical strips by integer amounts is always going to create a visual margin where you transition from one whole integer to the next.

Make yours a VERY large canvas and you might get away with it - the transition might be sufficiently small to fool the eye when taking in the whole image.

@cjmcguinness: I once made a set of tools to ease the stereogram manufacture process Stereogram Tools (beta). I didn't get around to releasing them as they didn't seem that popular (the plugins that is).

You might find them useful.

You might find them useful.

The 'Backfill' effect is definitely useful, cuts down on a lot of tedious work. However, the 'Echo' effect would benefit from a greater scale of Vertical echo height - 512px seems a bit limited, especially if you want your stereogram to be 800x600. Also, I tend to try and make my backgrounds look as seamless as possible.

I have been starting with something like a 100x600 strip and using the Random Shape Fill plugin to cover the area (repeated), then with the Panelling effect I shift it 50px so the seam is in the middle, then select a 60px wide strip, in the centre, and use the Random Shape Fill again to cover the seam (this time keeping all objects inside, so none cross the edge).

This creates a nice 'tileable' texture. Your 'Echo' effect would be great if I could then paste this into a new layer and 'echo fill' across, however (again) it only works if the image is less than 512 in height. Maybe if I created a 300px height tileable texture I could then panel this in two rows, but I prefer full height strips.

Good work on the 'Backfill' though, I will definitely be using that on any future efforts.

Cheers

Good point. I'll increase the Echo maximum to around 1000px. That should satisfy most users.

I'll let you know when it's uploaded.
