Graphics Engine Overview
DLHD, DL.3 and AxonHD Media servers use virtually the same graphic
engine software to control content selection and playback, as well as 3-D
Object and Global manipulation.
Protocol Options
The Axon HD, Axon HD Pro media servers as well as the DLHD Digital light use the latest HD
Protocol for control. This protocol version allows for control of up to 10 graphic layers per output
on the Axon HD and HD Pro Servers and up to 9 graphic layers on the DLHD. Limited backwards
compatibility is provided for the V2 protocol on the Axon HD, HD Pro server and DLHD fixture.
You can adjust the footprint by patching only the number of graphic layers you need for a
minimum of 1 Global Layer and 1 Graphic Layer for the Axon Servers. The minimum footprint
for the DLHD is 1 Motion Layer, 1 Global Layer and 1 Graphic Layer.
You select the protocol level in the fixture’s onboard menu system for DLHD and DL.3 fixtures
from the onboard menu systems or through the CMA for both fixtures and Axon media servers
(see Viewing Server Configuration on page 276).
Image Optimizing Controls
Using Live Effects in additional to the Black Level and Contrast Controls, you can adjust the
image for each cue. It is not necessary to precisely optimize images before preparing for a
show.
Graphics Control Hierarchy
There is a hierarchy to the DMX control parameters. In general, object control parameters
render individual graphic images. Global control parameters act upon the composite image
created by combining multiple objects. Motion parameters control the fixture movement and
projection.
It is especially important to keep this in mind when applying graphical effects. At the lowest
level, Graphic effects are applied to an individual 3-D Graphic Object. Any Global effects applied
affect each object in the combined Object image. Finally, motion effects control the projection of
the composite image.
