What is "Floating Window" !

By Shahrokh Dabiri.



Look at the Anaglyph picture below. This is a stereo picture with too much contrast. 

You know such pictures never come out well in anaglyph format, particularly when you may want to print them.

As you see here, there are a number of unwanted ghosts around the sculpture’s head or around her scarf.

Previously, unfortunately, sacrificing the “Stereo Window” position or creating a hard “Window Violation” 

have been the most common ways of treating such ghosts.

But fortunately there is a better way and it is the "Floating Window" !

Look at the anaglyph picture below. Although my Left/Right chips have been overlapped on the sculpture’s head,

there is no “Window Violation” here. Isn’t it interesting?

As you can see on the picture above, a second frame (and the brown frame) has been added to this pair

that now jump outward toward your eyes.

These new frames help me overlap my Left/Right chips on the picture background.

Here, in this instance, on the sculpture’s head.

With this "Floating Window" solution, I can treat the unwanted ghosts without any need

to sacrifice my picture’s stereo window.  


Now let me explain how I have created such a "Floating Window".

1. I need 3D software like SPM or such, to mount my picture and also to fix its 'Stereo Window' position correctly.

2. I should save my Left/Right chips separately to use them on the further steps.


3. With a powerful picture editor like 'Photoshop' or such, I need to create a big enough background for the job base

(In case, I need to crop its excess at the end) .

On this example I used black color for my base frame because it is an anaglyph friendly color

(it can be any color you would like but it should be different from your screen color).

4. Then I added two equal size brown rectangles on my black base. Those rectangles must be a bit larger than each stereo chip.

(The brown rectangles can be in any color you would like but it should be different from its base color).

Here the base frames should look like the picture below;

5. Now my Floating base is ready for pasting the chips. I added the Left/Right chips over the brown rectangles.

After pasting the chips, the image should look something like the picture below;

6. I should 'Save' the picture above. At this stage the job is almost done.

I just need to open this new stereo pair in my anaglyph creator software to make my new anaglyph with its new frames or its "Floating Window"!

This "Floating Window" solution lets me overlap my chips anywhere I like - from its deep background to anywhere on its foreground without being worried about

violating the 'Stereo Window' position!

On this example, I overlapped my chips on the sculpture’s head.


Let you know, creating procedure of the "Floating window" can be modified to only one base frame (here the white base).

I mean the second frames (on my previous example they were brown rectangles) can be ignored but personally I don't like to do that myself.

If you ignore installing the second frames your final floated anaglyph may looks something like the example below. Although the result will be a correct 

"Floated Window" anaglyph and works but it doesn't look as beautiful as the previous 'two frames base' method, I think so!

Meanwhile, for a while I was thinking myself to do something with those second frames (here the brown frames) or find a logical reason for it.

Fortunately finally I reached to a nice solution and it was a stylish frame like the example below that it easily can be used instead of the second frames;

You may want to use any kind of frames, from stylish one like my example to modern looking frames, it's depend on your taste!

Anyway you can find a bunch of these stylish 2d frames (hi resolution frames) on my site,  http://www.3diran3d.ir/Frames/

On this example not only I used a stylish frame but I also converted my 2D frame to 3D to get more realistic shape on my final picture.

you may agree the 2D-3D converting of a simple frame like what I made for this example picture is not a hard job.

Anyway you may use a flat 2D frame instead of the second frames (instead those brown rectangles) and your picture still will looks great, I believe.

On selecting this wedding picture I had an intention too. Most of us stereographers would liked to make a 3D album from the wedding

ceremonies we have attended before but those offending unwanted ghosts always had hesitated us on doing that, I guess.

Take a look at my example again, as you see both bride and groom look clear sharp in my floated anaglyph. Even we may enjoy the picture without wearing our glasses!

I suggest,  you 3D fellow take your stereo rig to the further wedding ceremonies you may attend then soon later you may surprise the new married couples

by your amazing clear sharp and printed 3d pictures, just you need to add a "Floated Window" on your pictures before!

Also by this "Floated Window" technique, there will be real potential in producing magazines, like the USA Sports Illustrated, using the overlapping technique

so that the pictures can be seen OK in 2D by the wider community and in 3D by those prepared to persevere with the anaglyph glasses provided. 

Once the ghosting problem has been largely overcome, many more will get practice in viewing the anaglyph way. 

Of course, like I said, overlapping the area of primary interest would be the key!

Although this "Floated Window' technique strongly may helps you on controlling the unwanted ghosts on your anaglyphs but don't over do that please

because many anaglyphic pictures already are really ghostless or they don't need this "Floated Window" solution thus why we may do that!


Here, let me explain how this "Floated Window" technique invented or where it has come from!

Long ago when I created the Anaglyphs group on the web (http://tech.groups.yahoo.com/group/anaglyphs/),

many from the best powerful anaglyph producers of the world from different countries and many anaglyph fans,

accepted my invitation and joined the Anaglyphs group.

Not only we share our anaglyph pictures but we always have discussions about creating the best possible anaglyph pictures.

in fact this "Floated Window" subject began, hammered and matured on the Anaglyphs group and by its members.

Now I as the owner of the Anaglyphs group and the representative of its respected members, dedicate this technique to all 3D enthusiasts of the world.

hope you enjoy this amazing technique!

I'll be glad to answer any possible questions regards in this technique. you can easily reach me by my email address below;

More examples; 

You may improve or add more beauty to your "Floated Window" by your creative frames instead of using simple rectangles.


New couple                                                                                                      Tehran

Here I have used two heart shape frames. there is no limit on numbers of frames you may like to create.

Any other creative frame form or shape could be used too.

On this example the stereo chips have been overlapped on the middle ground subject, here the couples!

Example No.2

Barbod                                                            Zinat wax museum Shiraz, Iran.

For creating such a curved frame, when I finished my picture then I just drew two concave curves on my frame sides and by a gray brush/pen

(I used gray brush because my Base color was gray)

Also you can create that concave frame by two modified rectangles like the Parallel pair below;

Modified rectangles for creating a concave frame

 Example No. 3

Craftman                                                   A craft shop in the handicraft bazaar of Shiraz city.

On this example my frame looks convex but like the previous example I just drew curves on my frame sides and by a gray brush/pen.

(I used gray brush because my Base color was gray)

Again you may make modified rectangles before creating your final anaglyph.

Notice; on this example my Left/Right chips have been overlapped on almost foreground subject or the man face!
