KEYSTONE FEATURE (STANDARD MODE)
The keystone feature available in the Standard Mode of the protocol gives a basic
modification to account for minor projection angle variations. There are 2
parameters give for this control, Keystone X Ratio and Keystone Y Ratio. When
modifying these parameters, the image is rotated around their X axis or Y axis
respectively, this gives a basic modification
KEYSTONE FEATURE (EXTENDED MODE)
The keystone feature available in the Extended Mode of the protocol uses 4 corner
points, with an X/Y position control at each corner. The 8 control channels give
detailed control over keystone modification. These parameters allow independent X,
Y control of the 4 corners. In addition to the corner position modification, the linearity
of the image can be adjusted as well. This adjustment allows for warping the image
when projecting at shallow angles. These warping controls are labeled Keystone X
Ratio and Keystone Y Ratio. The images below show the Hog4 slot toolbar layout.
COLLAGE GENERATOR (EXTENDED MODE)
The Collage Generator system is part of the graphics engine that allows multiple
devices to work together to create a larger, virtually seamless image. The graphics
engines of multiple servers can work together to create this much larger image.
There are various modes that the Collage Generator can work, Standard Collage,
Multi-Pane Collage, Standard Wrap, and Multi-Pane Wrap, all with various blending
options. These various modes will use content differently to create the final full image.
Standard Collage
In the Standard Collage options, the content is automatically 'sliced' into cell
segments by the graphics engine when you define the array size. This yields good
results in situations where moderate output resolution is suitable. Be aware, each
graphic output is using a full resolution image file and only projecting the needed
portion of the image, which can impact performance.
Multi-Pane Collage
In the Multi-Pane Collage options, the content is NOT sliced by the server and must
be sliced before importing. This situation allows a much higher resolution output of
the total collage. Using Multi-Pane Collage gives you the option to use video files
that match the resolution of the display devices exactly.
Wrap
In the Wrap option, the blending area of the first and last image are repeated on
the edge, so that they can be overlapped when build a cylindrical projection. This is
required for a virtually seam-less output. Multi-Pane example, if you have four
Emotion fixtures using a 4-part Multi-Pane Collage with individual 1024x768 video files,
the resulting collage resolution will be much higher. In standard collage modes, a
single file is divided by the number of parts in the collage. This method may not be
visually acceptable on a large screen.
