And if you then make some adjustments to the various controls for each of the nine squares, you might end
up with something like this:
Note: In the 2D representation, the screen objects don't move but the texture does, resulting in a jumbled image. In
the 3D representation, the screen objects move, but the overall texture is not jumbled and is viewable where the
screen objects are. The edges of the screen objects are not visible/shown, only the portion of the screen object that
has texture on it.
This completes the example tutorial. Now you can go ahead and try something more complicated, or just change
some of the values and/or control types in this existing configuration. Adjusting the min and max values for the
various X & Y controls may help the result to be more realistic or correct. For a simple control type change, swap the
opacity controls to be rotation controls.
You'll probably want to change to an 8-bit 127/128 data type and adjust the scale value if you try changing
from opacity to rotation.
Discrete Mapping
It is very easy to take the existing Projected Mapping configuration (created in the "Pixel Remapping Tutorial" on
page 125) and make an additional configuration that uses the same screen objects but with Discrete Mapping
instead. You can use the copy and paste functionality to make a copy of the configuration created in the tutorial. All
you have to do then is remove some controls from each of the screen objects.
Copy and paste the first configuration, then rename it so you can tell it apart from the first. Then, click on the arrows
to the left of each screen object to expand and show the controls. With discrete mapping, the texture is going to stay
pinned to the screen object no matter where it moves. So all you have to do is delete all controls that deal with texture
positioning. (But don't delete the controls that handle the positioning of the screen objects themselves.) If you labeled
your controls as in the previous tutorial it will be easy to make the deletions. Select any control that starts with "tX" or
"tY" and press the [delete] key.
Be careful though, as there is no undo!
You might think that you would want to rearrange the Art-Net channels for this second configuration, but you probably
don't. The nice thing is that the same external control still controls the same features in both configurations. Since you
can switch from one configuration to the other on-the-fly (using the Animation A parameter on the layer) it's easy to
use additional configurations at any time. Keeping the same patch for the controls means you don't have to change
those values when switching configurations.
