CHAPTER 6
Graphic Functions: Defining Content
44 DL.2 User Manual
Content Selection Parameters
The following sections outline parameters you will use to create an image from content and
define it’s playback. You will set the parameters described in this chapter for each individual
Graphic Object you define.
Note: The suggested default DMX values given for each parameter are recommended
to build libraries that provide the easiest and most reliable content selection,
rendering and output. They are the default values built into the Wholehog
libraries for High End Systems consoles.
Object
The Object parameter selects the 3-dimensional object component of an image. Object files
are the 3-D object shapes used to build a total image. The DL.2 graphics engine supports a
combined total of 255 stock and user-created object files.
Stock Objects have a fixed DMX value and cannot be edited. DMX values 1-149 are reserved for
identifying stock object files. User created object files must be assigned a unique DMX value
from 150-255.
For a reference of 3-D object files available as stock content with your DL.2 fixture and
information on how to create your own object files, go to the link for the Stock Object Guide on
http://www.highend.com/support/digital_lighting/dl2supportguide/ .
Default DMX Value: 1 = full screen flat surface
TIP: You can select the same object file for images that will be interacting with
each other. If both objects occupy exactly the same area in 3-D space,
“Z-fighting” (a shimmering effect) on some portions of the composite image
can occur as the graphics engine tries to determine which object should be
in the foreground.
You can avoid this effect by making a slight adjustment to one of the
object’s scale or moving it forward or back (using the Z Position parameter)
in respect to the other.
