CHAPTER 12
Global Functions: Collage Generator™ Effect
DL.3 Digital Light User Manual 133
Collage Setup Example
Here’s a typical scenario for setting up a 2 x 2 central panorama collage effect.
NOTE: If you are going to be mapping your collage to a sphere, you will need
to roughly adjust the output before you set up the collage, (see
Spherical Mapping Setup Guide on page 134).
Setup the collage effect:
1. Select the same content on four media servers.
NOTE: Any parameter adjustment to a graphic object must be set on ALL
graphic objects that are a part of the collage. For example, if you are
configuring Graphic Object 1 on four media servers to project as a
collage and want to apply a color effect, that effect must be
manipulated on Graphic Object 1 of all four media servers.
2. On all the media servers you are configuring, set a Global Effect Mode channel to a DMX
value of 141 to select the Enhanced Collage Generator option.
TIP: For the most reliable performance, use the same Global Effect Mode
parameter on all the Graphic objects to set up the collage effect. This
also leaves the other Global Effect Mode parameter available for
adding a second effect like spherical mapping to the composite
image.
3. On all the media servers you are configuring, set Modifier 1 DMX value = 1 to activate the
array options. The selection grid will not appear until the first modifier is set above 0
4. On all the media servers you are configuring, set Modifier 3 DMX value = 255 (100%) to
display the selection grid.
5. On all the media servers you are configuring, increase Modifier 1 to a value between 1 and
63 to select a collage array configuration.
6. On each individual server, set Modifier 2 DMX value between 1-63 to select the grid cell
that media server will project
7. Use Position, Keystone and Ratio parameters to align the projections of the individual
media servers in such a way that there is some overlap between the separate portions of
the image. This overlap is needed for blending adjustment.
8. Set Modifier 3 to a DMX value between 192 and 203 to define a hard edge for alignment.
Readjust Position, Keystone and Ratio parameters to bring collage elements into good
alignment.
9. Increase the Modifier 3 DMX value = 203-207 to blend the overlap between the outputs.
Readjust Position, Keystone and Ratio parameters to bring collage elements to fine tune
alignment.
10. On all the media servers you are configuring, set the Global Effect Mode Modifier 3
parameter to a DMX value to the default range of 0-127 (with edge blending) or between
128-159 (without edge blending) to put the media server output into their cropped collaged
state. The choice between the two values will depend on your preference for aligning the
images.
