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
128-143 (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.
Execute the panorama Collage:
1. Create a setup cue that identifies the content media file and folder, sets the Play Mode
parameter to Pause and Rewind to In Frame (DMX = 5) and the Opacity to 0 for the same
graphic object on all units you are configuring for the panorama.
2. For this example, follow with a cue that sets the Play Mode parameter of Play Loop Forward
(DMX = 0) and brings up the Opacity to 100% for the same graphic object on all units you
are configuring for the panorama.
Variable Edge Blending
Variable Edge Blending is used in conjunction with any of the Collage Generator Modes and
allows for on-the-fly adjustment of blend overlap between projectors. Using this mode gives
more flexibility for sizing a collage to a given screen or projection surface, as well as smoother
blending if wider blend regions are used.
The Variable Edge Blend adjustment allows for blend region adjustments from 0% (hard
edge) up to 50% of the image size. Horizontal and vertical blend regions can be controlled
independently of one another.
Variable Edge Blend is turned on by setting the Viewpoint Mode parameter to a value of
128. When variable edge blend is used, the view point mode will default to spherical universe
and cannot be changed. The view point position modifiers then become the modifiers used for
adjustment of the blend region sizes.
When active, the Viewpoint modifiers function as follows:
Modifier 1 (Viewpoint X Position): Horizontal blend width adjustment (Vertical Edges) from
0 = no adjustment to 255 = a maximum overlap of 50%.
Modifier 2 (Viewpoint Y Position): Vertical blend width adjustment (Horizontal Edges) from
0 = no adjustment to 255 = a maximum overlap of 50%.
Modifier 3 (View Point Z Position): Not used.
Because both Modifier 1 and Modifier 2 default to 32768 when they are used as Viewpoint
Position modifiers, they will default to the same when Variable Edge Blend is activated. With this
value, the blend regions are set to approximately 25% overlap.
NOTE: When Variable Edge Blend is used, all of the servers in the collage
must be set to the same vertical and horizontal blend overlap values.
If this is not done, the collage will not align properly.
