Pixel Mapping - ETC Hog 4 Series User Manual

20.5 Pixel Mapping

One of the more complex objects that can be added to a plot is a PixelMap. A PixelMap
allows the fixtures inside of it to dynamically change their parameter values based on the
PixelMap Layer content being sent to the PixelMap. This process is called PixelMapping.
Section 20.2.3 covers how to add and remove PixelMaps in a plot. In this section we will
discuss how to add and assign PixelMap Layers to PixelMaps, how to program fixtures to use
PixelMap values, and how to manage PixelMap Layer content.
20.5.1 PixelMap Layers
PixelMaps are responsible for mapping media content onto lighting fixtures, but, they do not
supply the media content themselves. The content comes from programmable fixtures known
as PixelMap layers, which are added to the show using the fixture window. Once added to the
show PixelMap layers are then assigned to PixelMaps.
To add a PixelMap layer fixture to the show:
1. Open the patch window.
2. Click on the fixture schedule button.
3. Look under the "Hog" manufacturer for a fixture called "PixelMap Layer"
4. Use the count column to specify how many PixelMap layer fixtures you want to add to
the show.
5. Click O K
To assign a PixelMap Layer fixture to a PixelMap:
1. Open the plot containing the PixelMaps to which you wish to assign PixelMap layers.
2. Enable the PixelMap edit button at the top of the plot window.
3. Select a PixelMap in the plot.
4. Locate the "Pixel Map" section of the properties tray located on the right hand side of
the plot window.
5. Under the text label "Layer fixture patch" you will see all of the PixelMap layers
scheduled in the show.
6. Select the layers to assign them to the pixel map.
Important: Regardless of the user numbers you assigned to the PixelMap layers, they are
layered onto PixelMaps using the order in which you select them in step 6. Layer order is
important when working with multiple layers as Z position is not adjustable: High numbered
layers will always appear on top of low numbered layers.
