To better understand the mechanisms explained below, it is advisable to read this article first:
Output Mapping  

In some situations, it is necessary to map content pixel by pixel to the output. An example of this would be a display on a façade equipped with individual pixels or tubes.

With standard pixel mapping using feeds (normal LED mapping), you would have to create a separate feed for each pixel in order to then position it at the desired location on the output.

This quickly results in hundreds or even thousands of feeds, which are no longer manageable.

If LED panels are used as screens in PIXERA, it is possible to load this mapping into PIXERA using .csv or .pfm files.
This creates a single feed that contains the entire remapping.

Before doing that, it is necessary to set the “Selective Target Rendering” of that LED to “Texture per Screen”. This setting can be found by selecting the LED in the Screens Tab -Render Settings - Inspector.

The .csv file can be loaded in the Inspector of the selected mapping under ‘Warp’.

The 'war'p' is only visible on the output but not in the warp window on the right hand side.

Before loading the .csv file

After loading the .csv file

The .csv file only contains coordinates for the source position of the pixels and the destination position of the pixels. the example .csv file which was used in the example above, can be found below as well.

Download sample .csv

After importing the .csv file, PIXERA automatically changes the file type to .pfm. Alternatively .pfm files can be loaded directly as well.

If the source is larger than the destination (i.e. the resolution of the created LED is larger than the resolution of the output), pixels that are outside the output resolution can still be mapped so that they are within the output resolution.
