In this laboratory, the Layers produced from photos or sketches are assembled to make animations or stereo pairs.

The laboratory is able to create every possible application for lenticular use but is also of use for 2D>3D conversion and for producing ordinary graphics animation.

For ordinary graphics, the laboratory is of great help for adding parts from other images to a single image and for creating special effects.

For lenticular applications, the laboratory makes the preparation and checking of the work far easier and for the creation of lenticular stereo images it is possible, and easy, to produce real depth planes (frames) that, unlike interpolated frames, maintain the fidelity of the original graphic sources.

When assembling the layers for 3D conversion, the laboratory allows you to easily move them into the perfect 3D position and readily determine the areas that require retouching.

A major advantage is that you can work on two images simultaneously, which not only reduces execution-time but also allows stereo viewing of your work-in-progress.

For animating photographic or real images, this laboratory does not impose any limits on your creativity and it also allows you to create stereo animations.

The laboratory directly saves the work, in a single operation, in a form suitable for lenticulars and to which all of Gugle's movie functions may be applied.

Concepts

For further information regarding Layers, the procedures for extraction, examples and applications see "Direct Layers LAB". For information regarding Layers automation see: "Algorithms to Layers LAB".

The "Layers Assembly" laboratory is intended for working with Layers and with frames.

The Layer contains selected parts of an image while the frame is the base or the space on which the Layers are arranged.

An animation is formed from different frames that, when observed in rapid sequence, display the subjects as animated.
The laboratory allows you to move single Layers into any position in the frame and for every frame it is possible to record different positions for every single Layer.

The Layers are processed in a hierarchical order, the one at the top of the layers list is the first to be drawn and the following layers overlay those preceding.
This hierarchy is important because the Layers are presented in a pre-arranged and logical order in the scene.

This laboratory is significantly different, however, from the usual animation software that can only operate with ordinary graphics while 3D Gugle operates in the stereoscopic and lenticular domains where the principles and methods are obviously different.
"Layers Assembly" is most easily conceived not as a single laboratory but as eight separate laboratories, each specialising in a particular activity.

The activities that can be carried-out are the following:

1) creation of ordinary single-image graphics composed from parts of other images or Layers
2) animations of ordinary graphics with real images
3) composition from Layers of stereo images with only one reference (right or left).
4) composition from Layers of stereo images with dual references, half in the right side and half in the left side.
5) production of frames for lenticular printing for any known type of lenticular application
6) production of real frames (not interpolated) for lenticular printing with a stereo origin
7) production of stereoscopic animations
8) production of animated Layers

The work produced with this laboratory is also perfectly compatible with the other 3D Gugle laboratories.

    Rotate Layers

After opening an image from which you wish to extract a layer, select "2D to 3D/Layers Assembly".

In the "Layers Assembly" environment, the preceding menus are deactivated and a new dialogue will appear.

Before describing the functions of this LAB let us look at these menu options in the "Layers Assembly" dialogue.

"Add Layer(s)"
This menu adds Layers to the background image.

When you click on this menu in the file-opening dialogue, it is possible to make multiple selections. In other words you can open many Layers at the same time.

The Layers can also have different pixel-dimensions and ordinary *.gna, *.bmp images may also be added.

The ordinary images do not support transparency but can be useful in many cases and particularly for changing the background animations.

This LAB has powerful Layers-animation capabilities. It is possible to move up to 128 (0-127) layers concurrently.

The project is very compact and well optimised but to obtain the best results requires a fast processor and sufficient RAM memory to suit the task.

If your computer does not have sufficient resources, you can still work by using 3D Gugle's preview feature..
3D Gugle can operate in multi-session mode. In other words you can open two or more instances of 3D Gugle and work in either session.

To see the preview, you first save the frames and then reopen them in one of 3D Gugle's LAB's specialised in movie and frames management.
Remember, to create a new movie with 3D Gugle only requires two clicks of the mouse.

Very often animations require duplicate Layers and this LAB can provide them.
In other words, you can open the same image many times as a new Layer.

Rename them by right-clicking the Layers list and selecting "Rename".

The new Layers are immediately inserted below the currently-selected Layer .

The hierarchical position of the Layers is very important for correct visualisation, but in all cases it is easy to move a layer to a new position.

To move or cancel the layers you use the dialogue buttons. These will be described later.

"Save all frames"
"Save all Frames" saves all the frames of the animation between "Frame Start" and "Frame End".
If "Frame synchro window" is active, the frames saved are the frames of the main window or synchro window depending on which selection button ("Synchro" or "Main") is pressed.

3D Gugle can only produce 1024 Frames at a time, representing about one minute of an average film, nevertheless it is better to work on shorter clips as they are easier to manage.

The frames saved with "Save all frames" can used for lenticular printing, for creating digital films or for creating a "Layers scene"

The "Layers scene" is a series of frames that are reusable as Layers in the main scene or in other animations.

To understand the concept of the "Layers scene", imagine an animated overlay (such as a company logo) that can be added to any of your other animations.

When you want to save a scene as Layers , simply deselect the "Visible" box for all the Layers that you do not want to include.
You must obviously repeat the deselect action for all the frames of the scene.

The animated-logo overlay is just a simple example. 3D Gugle can create animated Layers for any subsequent use.

An example of "Layers scene"

"Save visible frames"
This menu saves the frames that have currently visible Layers. In other words it saves a screenshot as a Layer.
When used in conjunction with "Frame synchro window", the saved frame will be the left or right depending upon the selection of the keys "Synchro" and "Main."
This function is very important and is normally used to compose a new Layer that can be opened and used in your current scene or any other scene.
To open the new Layer, use "Add Layers"

"Save frames data"
"Save frame data" saves the position data and visibility of every Layer for all the frames.
This function also saves the data of the frames in the "Frame synchro window".
Saving the data is not only a safety measure, it also enables you to create different versions of the scene and choose the best.

"Load frames data"
"Load frames data" loads the data saved with "Save frames data" and applies the data.
When the data is used by "Frame synchro window", it is best to have previously opened that window.
For further information, see "Frame synchro window" in this document.
Top

"Copy visible image to clipboard"
This works like "Save visible frame" but instead of saving the image, it copies it to Window's clip board.
When working in combination with "Frame synchro window", the copied frame will be the left or right depending upon the selection "Synchro" or "Main."

Top

"Autoset X to zero, Autoset Y to zero"
These two functions zero all the position values of the frames for the X or Y axis.
Zeroing begins from first up to the last frame (1023).
This function is used for cancelling the current values and resetting from a selected frame.
The functions do not change the visibility state of the single frame.

"Auto Step X Y"

When you click on "Auto Step XY" , the necessary controls are displayed to allow setting the automatic change of the Layer's position.

Before describing this function, you are reminded that every frame retains the position data of its Layers and every Layer has three data elements: one for the X axis, one for the Y axis and another for its visibility.

With the "Auto Step XY" function you apply a fixed increment or decrement (in pixels) to the selected Layer, or all the Layers, for the X and Y axes.
The increase is relative to the current position.
The increase is applied from the next active frame up to the last frame (1023).

You use this function when you want to move a Layer in the scene a fixed number of pixels.
Obviously, the function automates and speeds-up the insertion of the data but the same operation can be performed manually by inserting position values for every frame.

The calculated values will automatically be limited to the maximum positive and negative thresholds.

In other words, when the Layer is moved too far to the left or right and moves off the screen, the automatic values are no longer increased but remain at their last allowable value.

Under the pale-blue "Layer Name" label is the name of the active Layer .
The active Layer is what receives the operations that are performed.
The operations of auto-increase can also be performed on other Layers without closing the function dialogue.
To activate another Layer on which to perform some operations, simply select it from the list of Layers to the left.

The two pink labels display the X and Y values of the active Layer for the selected frame.
The selected frame is that indicated by the "Frame base start" spinbutton.
To select another frame, click the spinbutton arrows or directly enter the values and press "Enter".

The logic behind "Auto Step" although a little difficult to explain is essentially simple and some practice will be needed for a complete understanding.

In other words, when you want to uniformly move a layer in a scene, just use the "Auto Step" function.
The greater the "Step" value the faster the layer moves.
The "Step" value can be positive or negative, the value corresponding to the direction and amount of movement in pixels .
The example below illustrates this.

The movie comprises four layers (the small boat is duplicated) overlaid on an ordinary background image and to which various "Auto Step" options are applied.
For the small boats, the Y axis increment is zero (they do not move up or down the screen) while the X axis increment is 5 pixels per frame for the upper boat and 4 pixels per frame for the lower boat.

For the large boat in the foreground, the Y axis increment is zero and the X axis increment is 5 pixels per frame

For the red dot, the X and Y increments are set to zero for half the frames and then for the rest of the frames to an increment of one pixel for the Y axis.

The chart above shows frame 0 has a starting value of 10 and each of the following frames is 6 pixels greater than the preceding frame. The resulting value is shown as 'total value'.
The automatic increase begins after the selected frame (which is shown in blue).

If the step amount is zero, all the following frames will be set to the start value
and the layer will no longer move.
This function is essential for fixing the position of a Layer inside the sequence of frames.

See also the below example

The blue "Only selected Layer" and "All Layers" buttons determine whether the same increment values are applied to the selected Layer or to all Layers.
This last function is essential for fixing the position of the Layers that will have a zero increment step applied.
On selecting "All Layers" a check button "First Off" become visible. This option excludes the first frame from the increment operation.

Before starting the "Auto Step XY" function, it is essential to bring the Layers into their starting position using the ordinary "Layers Assembly" functions.
Selecting "Sum" the value of the increment is added to existing value.
This option is very important to moving the Layers scene that have a proper implicit movements.
Before using the Add function with the option "Sum" it is essential to clone the data of the Layers group with the menu "Clone" and "Fill" selected.

See the below example

The "Auto Step XY" function does not modify the visibility state of the Layer.

The "Apply" button executes the function while the "Undo" button cancels it if you have made an error.
"Undo" only cancels the last operation and not any previous ones.

The "Close" button closes the "Auto Step XY" panel and reactivates the ordinary environment of "Layers Assembly".

"Layers Visibility"
With "Layers Visibility" it is possible to make the selected Layer or all Layers visible or invisible for all the frames (0-1023).

On selecting "All Layers" a check button "First Off" becomes visible.
This option excludes the first frame from the operation.

It is often necessary to visualise a frame just once for a whole scene. In these cases the "Layers Visibility" function will help you quickly achieve that.
In the example below, every frame is visible just once.

The functions are also useful when you want to temporarily exclude from the preview the visibility of one or more Layers.
By setting visible to "False" you not only exclude Layers not currently required but you also increase the speed of the dynamic preview,

To produce this film, all the Layer visibilities are set to "False" and then, to flow through the frames, the corresponding layer of each following frame is made visible.

To set "Invisible" a Layer for a determined group of frames you first set the Layer in Out of screen and then you apply "Auto Step X Y" setting the "Amount" to zero.
To move a Layer in "Out of screen" use the scroll Bar "X" moving to the max value of the left direction.

"Clone Data"
This function will clone a series of layers in normal or inverted order.
It allows you to repeat a specific scene from the main scene.
On pressing "Clone Data" the cloning control panel is displayed.

Set the number of the starting-frame in "Frame Start" and the ending-frame in "Frame End".
Clicking the spin buttons provides a preview of the frames at the beginning and end.

On selectiong the option "Fill" the data is repeated for all frames (1023)

Press "Paste INV" to clone the frames in inverse order.
The inverted sequences allow you to create continuously-cycling scenes.

Pressing "Paste" clones the sequence in its original order .
The sequence is cloned to the frames that follow "Frame Start Paste".

In the example below, some parts of the scene are cloned in inverted order.

"Delete Frame(s)"
This function deletes the data associated with a single Layer or for all the Layers in a specific sector of the main scene.

When data is deleted, the data that was initially to the right replaces it.
If you want to cancel the data values without them being replaced by data to the right, use the function "Auto Step XY".
Before activating "Auto Step XY", set the Layer position to zero and then set the increment to zero.

"Insert Frame(s)"
The function moves toward the right the data of a single Layer or of all the Layers for a continuous group of frames.
The values in the vacated space are set to zero for the X and Y axes and visibility is set to "True".

The starting-point for the empty frames is determined by "Frame start Insert" and the number of frames to be inserted is determined by "Amount Frames to insert".

"Rename selected Layer"
Use this to rename the currently-selected Layer.
Using a logical, meaningful name for the Layer helps you to work more quickly.

"Synchro Window"
This menu opens the traditional 3D Gugle synchronised window used in all the stereo applications.
On opening, the window contains a copy of the image that you have opened in "Layers Assembly".
This window is normally used for the stereo preview but is also required for the "Rotate" section.Iin this case the window has to be open before accessing "Rotate".
The window contains some menus for automatic alignment and other functions.

For further information click here.

"Frames Synchro Window"
This window is only available in "Layers Assembly" LAB.

Besides providing a work preview, this window has a dynamic capability similar to the main screen.
In other words, it contains a copy of the Layers that can be positioned to any coordinates points for every different frame.
The window accepts the automation commands "Auto Step for X and Y" and its frames content can be copied and saved independently.

With the aid of this window you can, for instance, create the left scene of a stereo animation while creating the right scene within the main window.
Besides that use, it is also essential for producing AlfaD2 stereo images .

Frame synchro window also contains a menu with which automatic alignments can be synchronised with the normal window.

When this window is open, the control panel displays radio- buttons "Synchro" and "Main".

On pressing the "synchro" button some controls and the Save, Edit and Auto Step menus will have an effect on the image, Layers and frame shown in the "Frame synchro window". Pressing "Main" transfers their functionality to the main window.

Some commands act simultaneously on both windows: these are "Save frames data", "Load frames data", the frames selection spinbuttons and the "Visible" selection button.
The 'visible' attribute is common to the Layer of both the windows. In other words it is not possible to set the left layer "Visible" and the right layer "Not Visible".

The "Play" buttons animate both windows when "synchro" is pressed and only the Main window when "Main" is activated.

When "Frame synchro window" opens, the graphic memory data and the Layers data of the main window are copied into a new area of memory.
This "copying" function when opening the synchro window is very important because it greatly eases the work of Layers positioning.
In other words, when you open this window the main window state is preserved and is usable by the synchro window.
Remember that the left and right stereo image or stereo animations are very similar and by this copying method you only act on their differences.

Attention
If you have saved the data with "Save frames data" and the data is different for the main and "Frame synchro" windows , it is essential that you reload the data when the "Frame synchro window" is already open.
Remember that on opening, "Frame synchro window" always copies the data from the main window and overwrites the loaded data.

Normally, before opening a "Frame synchro window" for stereo work, the ordinary animation operating on the main window will have been completed, resulting in the left and right films of a stereo pair being almost equal, perfectly identical for all Y axis parameters and some differences for the X axis parameters.
With the "Frame synchro window" open, the work is completed by moving the Layers into this window with the X scrollbar.

Obviously not all situations are identical, for instance when the fixed part is dominant it is worth opening the "Frame synchro window" before beginning any work.

The stereo animation below (in cross-eyed format) was produced for checking the 3D effect, the Layers used are raw and not retouched.

"New Window"
The window contains a copy of the image used to enter "Layers Assembly".
In the window there are zoom menus.

"Rotate"
This function is intended for two specific applications:
A) the generation of real frames for lenticular printing of a stereo image
B) the assembly and preliminary testing of stereo pairs from 2D to 3D conversions.

The menu is active when there are at least 3 Layers loaded.

As an example of the possibilities provided by the "Rotate" function, the movie below shows a lenticular application of a stereo image.
The film has been produced with just a few clicks of the mouse and provides a simple check before printing.
The film uses 61 frames produced automatically from "Rotate" and 14 Layers.

"Rotate" uses the position data of the Layers previously arranged in "Layers Assembly".
This is a great advantage because it is possible to rotate a group of Layer even if they are not of the same dimensions.
For instance, in the film above, the two boats have different dimensions (they are from another image) that are both smaller than the Layer of the background scene.
In other words ,when "Rotate" starts, all the layers position data is copied into a new area of memory and used as default values.
This concept will be explained further in the description of the operational examples.

On clicking "Rotate", the controls for Layers rotations are displayed.

"The Rotate control panel"

The topmost "Frame" spinbutton navigates among the frames and the left/right arrows below copy layer data from the preceding or following frame.
These two buttons speed-up manual data insertion.

The "Center Rot" spinbutton determines which Layer to use as the centre of rotation.
If the spin has value zero, the higher Layer (first Layer) is used.

The "Increase" scrollbar increases or it decreases the horizontal magnitude of the Layer move.
Towards the right increases and toward the left decreases.

The scrollbar with the label: "Rot = 0" increases or decreases the angle of rotation on the central axis.
The maximum allowable rotation is from - 5 to + 5 degrees.
The rotation is applied in a linear and equal way on every Layer, each Layer counts therefore as a separate entity.
To obtain good results it is important that the Layers are extracted in a gradual way and without sudden depth jumps, in other words each Layer has to occupy the same amount of depth.
For instance, if a scene is 100 metres deep and you want to produce 10 Layers, each Layer should have 10 metres of depth.
If your Layers do not contain coherent spatial information it is convenient to use the "Layers Assembly" and do it manually.

The "Play all Layers" button displays a dynamic preview of the frames from "Start" to "End".
Set "Start" and "End" with the spinbuttons underneath..
On pressing "Play all Layers", the button changes colour and its legend changes to "Stop". Pressing again stops the preview.

The "Rep" (Repeat) button continually replays the sequence of frames.

The "Play selected" button is never active in the "Rotate" section.

On entering the "Rotate" section some main dialogue menus are disabled while others maintain their active state.
The Active menus are:

"File"
"Save all frames"
Saves all the animation frames from "Frame Start" to "Frame End".
For further information, see menu in this document.

"Save visible frame"
Saves the current frames. In other words it saves a copy of what is seen in "*. bmp" format.
For further information, see menu in this document.

Menu "Option"
"Auto increase for X"
Produces a sequence of position data using a fixed increase. It serves for automating the insertion of the data.
For further information, see menu in this document.

Menu "Edit"
"Copy visible image to Clipboard"
Copy the screen to Window's clipboard.
For further information, see menu in this document.

Note

"Button Exit Rotate"
"Exit Rotate" is the only way to leave the "Rotate" section and return to the normal state of Assembly Lab.

USING ROTATE
The procedure

In the ordinary section of "Layers Assembly"
    1) to arrange the Layers in the definitive spatial position
    2) to fix the data position using "Auto Step X Y" with zero increase
In the "Rotate" section
    3) to move the scrollbar "Rot = x" to -5 (left)
    4) click on the menu "Auto increase for X" to set a positive value for the increment.
    5) to determines by the "Center Rot" spinbutton which Layer to use as the centre of rotation.
    6) to set the correct horizontal magnitude with "Increase" scrollbar

Save the frames sequence from the menu "File\Save All Frames".
Prior save set the spinbutton "Frame End" to the last frame number of the rotation sequence.

Top Top Menu

The topmost "Frame" spinbutton navigates among the frames using the arrow buttons to move to the preceding or following frame.
The number of the active frame is displayed.
The button accepts manually-entered values after pressing Enter.
If you click on the manually-entered values, you can change them with the arrow keys or mouse wheel.

The "Visible" selection-button determines if the selected Layer in the layers-list will be visible in the active frame.
The visibility attribute of every layer of every frame is recorded .
When the "Frame synchro window" is active, the visibility attribute is shared between both windows, it is not possible to make the left layer "Visible" and the right layer "Not Visible" .

This functionality of "Visible" and "not Visible" is essential for making animations because it allows the sequences to be intermittent.
For instance, in the following animation the 6 Layers of the mouth are only visible one at a time and only on a single frame.

The Layers and background image (face) are shown in the sketch below.

The arrows under the spinbutton copy layer-data into the active Layer from the preceding or following frame.

The right-pointing arrow copies data from the preceding frame while the other arrow copies data from the following frame.
The arrow down copies data from the preceding Layer to the selected Layer but in the next Frame.
To see the result move one step the Frame Spinbutton.
The procedure is:
a) Select next Layer
b) Press the button
c) Move to the next Frame

These buttons speed-up manual insertion.

The X and Y scrollbars move the selected Layer along its respective axis.
The position of the Layer moved with the scrollbars is only valid for the active frame.
The scroll increment is a single pixel.

The labels associated with the X and Y scrollbars are active position-indicators and may be set to zero by clicking on them.

The "Play all Layers" button displays a dynamic preview from "Frame Start" to "Frame End"
Set start and end with the spinbuttons underneath.

On pressing "Play all Layer", the button changes colour and the legend changes to "Stop". Pressing again stops the preview.
This button moves all the Layers of the project from the first one to the last one of the list.

The action of Play changes if "Frame synchro window" is active. In this case if the button "synchro" is selected Play moves both the synchronised window and the main window. If instead "Main" is selected Play moves only the main window.

The "Play selected" button displays a dynamic preview for the selected Layer.
The purpose of this button is to quickly move the Layer on which you are working and excluding the other Layers.
The action of Play changes if "Frame synchro window" is active. In this case if the button "synchro" is selected Play moves both the synchronised window and the main window, whereas if "Main" is selected Play moves only the main window.

The "Rep" (Repeat) button continuously replays the sequence.

Under the Play buttons are spinbuttons that determine the beginning and end of a sequence preview.
As with all of 3D Gugle's spinbuttons, it is possible to change the values with the mouse or keyboard.
Manually-entered values are accepted after pressing Enter. If you click them they can be changed with the arrow keys or with the mouse wheel.

Attention
The Spin "Start" and "End" are not only used by the Play buttons, they are also used as reference when saving with the menu "Save all frames"

The "Speed" scrollbar sets the Play preview speed.
Moving the bar left decreases the speed and moving it to the right increases it.

In the lower part of the control panel there are three buttons which serve to move and manage the Layer position.
These buttons are visible only when a different Layer other than the first one is selected.
The two buttons with the arrows icon the selected Layer move up or down.

When you click to select a Layer in the screen only the Layers between the first one and the selected one become visible while the under Layers are not visible.
This method of work is essential because it allows you to see what really happens to the Layer on which you are working at that time. If all the Layers of the list were visible the Layer work could be covered by the other under Layers.
To see all the Layers you simply make click on the last Layer.

This Layers list-box as all the list-boxes used in 3D Gugle, accepts a series of alternative commands with the mouse or the keyboard.
To quickly move from the first one to the last Layer you can use the key "End" or "Begin".
To quickly move you a groups of Layers you can use the keys "Page down" and "Page Up".
To make a rapid scroll it is possible to use the mouse wheel.
To change the selection of the Layer by one position you can use the key "Arrows"

The button "Del" cancels the selected Layer from the list.

The button of selection "Prev" determines if the real time preview will be visible when a Layer is moved with the scroll bars of X and Y.
This functionality is necessary when there are many Layers of big dimensions or when the computer used has small resources.
On activating the button the visibility will automatically be restored.

The button "Hide" determines if the dialogue of "Layers Assembly" is visible. It automatically will reduce in size when it is not active.
When this button is selected clicking in any point of the screen or on another software the window reduces it to a small horizontal rectangle.
To reactivate the dialogue click on the same dialogue again.

With the "Zoom" menu the work area can be magnified.
The magnified image uses a good quality interpolation method.
If the option "Window" is activated the image is automatically resized when you change the dimension of the main window.
