Multiscreen

A calibration multiscreen can be used to calibrate curved or other shaped LED-Walls.

Basic configuration of defining the screen size, resolution and marker IDs are the same as a Single Screen. For details please refer to here.

*You can export a Multiscreen as FBX

The Screen can be added within the object tree.

The multiscreen is one object with contains multiple surfaces.

Each surface represents a part (like each column) or each single panel of the real LED-Wall.

!It´s important that the screen/surface dimension as well as the resolution is matching perfectly with the real wall.

With a secondary click on the object a “surface generator” can be opened.

*Changing the “Mode” to “Add” will just add the defined surfaces instead replacing all.

A curved LED-Wall setup could looks like this. (21 columns, each 0,5m width, 4m height)

Go now into the tab “Screen” and define the output mapping resolution.
For example 4096×2160px and click on “Generate Texture”.

Within the tab “SP Pattern” it´s possible to define the size for each single marker.
Change these for example to 0,25m.
Go back to Screen and click again on “Generate Texture”:

*Don´t wonder, that you will see black boarders.
This is to avoid pixel interpolation.

Within the Inspector it´s possible to now export the image as png.
Click on the ( I ) and click on “export marker image”.

*The mapping coordinate can be change for each single screen within the tab “Surfaces”

*It´s also possible to add surfaces manually within the inspector instead of using the generator.
Just click on the (+) within the “Surface” tab.

!By default the location orientation of the first surface will be not modified. (Master Screen)
This can be changed within the calibration tools.

Just click on Screens and select within the screen list the chosen screen.



You can now define the “Master Surface” in the inspector.
