Multidisplay Mode using several computers
The advantages of Wings Vioso RX,
such as immediate playback and excellent quality, can also be used for
multidisplay mode. Multidisplay shows are edited on the master more or
less just like any other single display show. However, a few additional
aspects need to be considered for multidisplay presentations that may
have a number of client computers.
Workshops for multidisplay applications
can be found here:
This is what you should consider
for multidisplay operation with several computers:
Multidisplay Mode
requires a Multidisplay License to be installed on both the master
and all clients. I.e. several dongles may be plugged into a computer
if it provides show content for several displays. Multidisplay dongles
are available for one or two displays. Note:
Wings Engines require no external dongles.
Create a new project using
the Wizard for mixed media projects. Doing so, will clearly simplify
screen configuration. See Wizard
for mixed media projects. Please mind the following settings:
In dialog
Multidisplay configuration
you can usually leave the default setting Manual
display assignment. Only if you are going to use a separate
PC for every display should you select Displays
on separate client PCs. This sets up a client for every display
in the device control system.
In
line Displays check box 
Screen fields so that one
screen field is created for every display. This is useful if you want
to check the assignment of the displays to the monitors or projectors.
Dialog
Timeline tracks offers selection
of option per screen field
next to Picture tracks, which
means that the corresponding tracks in the timeline are created as
well.
After
completing the configuration in the Wizard set up the client PCs for
the additional render hosts in the Media Pool. In the Media Pool click
on category 
Devices. Right-click the right
Media Pool section and select Add
client PC. Enter the client's IP address. If the client is
already available on the network you can click 
Select computer and select
the computer’s IP address. Add the other clients likewise.
Important note: When you have changed
the assignment of display PC, monitor and display while the Render Engine
was running, you need to terminate and restart the Render Engines for
the changes to become effective. See also Special
triggers for the Render Engine.
Now
you need to assign the displays to the outputs of the corresponding
client computers. In the Media Pool in front of 
Screens click the triangle and Screen
1, following which the screen fields and displays are listed
on the right. Right-click Display
1 and select Properties.
For Display PC enter the required
PC, e.g. Local Master PC,
and for Output enter the type
and number or letter of the output. If you are not sure about the
names of monitors and projects in Windows click Identify
in the Windows dialog for screen resolution. Assign the Display PC
and the corresponding monitor to all displays likewise.
In
order to open the render displays enable the network by clicking 
Enable network in the Tool
bar at the top. Wait until button 
Show
render displays can be clicked and do so. It may take a few
seconds until the render displays are reliably open. Wait for this
period to elapse before you start playback.
It
makes sense to check the assignment of the displays to the graphics
cards’ outputs now. To do so, place images and text objects with the
corresponding display denominations in the tracks that are linked
up with the display screen fields. See also Displaying
titles and text within a show.
Before
you start playback the media need to be transferred to the client’s
Render Engines. To do so, click 
Enable file transfer. The
progress of data transfer can be recognized from the Control Panel
control fields. If no control fields for the client PCs are shown
on the Control Panel drag the clients from the Media Pool Devices
and drop them onto the Control Panel.
If
the target is a seamless image projected by a number of projectors
you need to align the projectors using test images (e.g. grid pattern)
which you simply drag into the timeline. Locating on the render displays
is enabled by pressing F6.
For the adjustment of the projection images and creation of softedge
masks you need to resort to a camera and the separate Vioso calibrator
for the time being. It can be started by clicking Programs
- Vioso Calibrator in the
main menu. In principle calibration is done as described in topic
a Camera-based
calibration. However, you need to export the completed calibration
and import it again as follows:
In
the main menu Multidisplay
click VIOSO calibration....
and Load calibration.
After
loading and checking the previously created calibration click on Save as Startup calibration so that
is loaded automatically at Wings Vioso RX start.
After the
alignment has been completed you can start your show as usual.
