Checking your anaglyph glasses and monitor

Using the Synchro windows

The auto-synchronized windows are an important resource for working with stereo images.

In 3D Gugle you have two types of these windows: the "Synchro Window" and the "Synchro Window Half image"

When you open an ordinary Synchro Window it contains a copy of the main image.

If you open the "Synchro Window Half image", the main image is divided into two parts: a part is recopied in the Synchro and the other part remains in the main window.

The Synchro Windows are independent windows but synchronized with the main window.

If you move with the scrollbars or resize the main window the content of the synchronized windows also move and resize.

The Synchro Window has its own menu.

From the menu: "File" you can open an image.
The image opened in this way is contained in a rectangle with the same dimensions as the main image

From the menu: "Shift" you block or you de-block the possible movements.
For example if the menu: "Horizontal" is selected you can move the image of this window only in a horizontal direction.

To move the image of this window independently you have to drag with the mouse the image.
To move the image it is also possible to use the "Arrow" keys. To move rapidly use "Shift + Arrow" keys.

From the menu: "Window" you can line up the Synchro Window with the main window.

The menu: "Swap" has two different purposes depending on the type of Synchro Window that is used.

In the ordinary Synchro the "Swap" action reverses the left part with the right part of the Synchro image.

In the Synchro Half image the "Swap" action exchanges the two images.

Note
Remember to close these types of windows when they are not necessary. In this way you will save memory.

Stereoscopic Text

With 3d Gugle it is very easy to create and to add stereoscopic texts to your images.

We will begin with the stereo pairs case.

1) Step
From the menu: "File" select "New Canvas" and then set 640 x 200 pixel and the white colour for the background.

2) Step
From the menu: "Image" select "Special Function" and then "Write"
In Write Lab set the necessary parameters and to write the text.

3) Step
Select “OK” and save the bitmap text.
Now in the menu: "View" select "Synchro window".
In the menu of the "Synchro window" select "Window" and then "Tiled Main Right"
With a "Synchro window" you have an immediate preview of your work.

4) Step
In the menu "Image", select "Transform" and then "Free".
In the "Transform Lab" make any preferred deformations, if necessary.
Select "OK" to complete and save also this new text as a bitmap.

5) Step
Close the "Synchro window" and load your stereo image into which you want to add the text.

6) Step
From the menu: "File" select "Open Add" to add the first saved text into your image.
With the Box context menu (right mouse button) select "Transparencies" and then "white" colour.

7) Step
Repeat step 6 but you add the second saved text-image.

We will continue with the anaglyph case.

1) Step
You perform the same operation already described in the points 1-2 but use the black as backcolour.

2) Step
Now you go in the "Direct Anaglyph Lab" and then you make a 3D depth that you prefer or from the menu: "Option" you select "Perspective Control" to apply a stereoscopic deformation.

Checking your anaglyph glasses and monitor

Anaglyph glass verification

Fold up your glasses so that the red lens overlaps the cyan lens.

Now you look through the two overlapped lenses. If your glasses are accurate what you see is very, very dark.

The image below is an image sample and it is without errors. It has been produced by software and then saved in the png format. This format assures the complete preservation of the colours.

Close with the right hand the right eye and with the left eye look at the image below through the red lens.
If your red lens is good you see the cyan colour as black.
Now you invert the elements of the test and if your lens cyan is good you see the red colour as black.

For a good appreciation of the anaglyphs it is also essential to maintain a correct eye alignment with the monitor.
A correct position is that shown in the below image.

Monitor colours verification and setting

You have to first set/test for every single colour RGB and then for the whole colours using the grey table.

These colour settings you can alter with the options of the monitor or with the options of the video card.
For more specific information consult the user's guide of your device.

To regulate the colour of the single RGB colour you simply adjust the setting so that you can distinguish the greatest possible number of the little squares.

To make a regulation of the whole colours you use the grey table and you adjust so that the grey is really grey without any colour tones. You also verify if the black is really black and the white is really white.
