An Igloo Immersive Environment system consists of three main components: a Media Server, Igloo Software with tablet control interface and the Igloo Projection environment.
The Media Server comprises at least Igloo Warper and Igloo Control. Igloo Warper generates the video stream that is displayed via the projectors, if necessary adjusting the position and geometry of the video outputs so that the content fits the screen. When used with 5 projectors, this allows the media to be mapped to fit a 360 degree screen.
Igloo Control is where media and external sources are managed and configured for display by Igloo Warper. It includes a video playlist and a set of playback controls as well as the ability to manipulate the media and so it perfectly fits the screen, such as stretching and rotating. This can be the case if you are using media originally intended for use with VR Headset.
A Tablet provides a wireless connected interface, TouchOSC, to access system controls, Igloo Control and Igloo Warper communicate using the local area network using network messages to exchange information, this requires that the network must be set up correctly, even if the tablet is not in use.
Any recent Apple or Android device may be used as the tablet interface.
The Igloo Warping tool provides a computer based application that can be used in lieu of the tablet control interface. This is invaluable when a remote worker is warping the Igloo Projection environment from a physical location other than the physical installation location.
Configuration and Testing
Checking the Media Server Network Connection
It may be necessary to check that the local area network settings are correct. This will start with the Media Server. To find out what IP address is assigned to the Media Server, go to the Server Desktop : -
Enter the key combination; ‘Ctrl + R’
Type ‘cmd’ into the dialogue box which appears, then press return
Type ‘ipconfig’ into the window which appears, then press return.
Find the heading containing the phrase ‘Ethernet adaptor’. In this section, locate the row labelled ‘IPv4 address’. The numbers on this row, after the ‘:’ should be similar to the following, 192.168.0.100, this is the IP Address of the Media Server, note this down for later reference.
Checking the Igloo Warper and Igloo Control Connection
In order for Igloo Warper and Igloo Control to communicate with each other the network settings of the applications must be checked. Igloo Control needs to be provided with the Media Server IP address.
To establish a connection: -
Open Igloo Warper on the Media Server
Open Igloo Control on the Tablet, press ‘G’ key, to open bring up the settings panel
In the text box under the heading ‘Screen 1’, enter the IP address of the server, e.g. 192.168.0.100:9001
Press the ‘Test Connections’ button. The red indicator next to screen 1 should become green.
NB - pressing the test connections button actually establishes the connection, if the screen 1 indicator is not green, the Igloo Control app will not pass messages to the Igloo Warper, even if the IP address and port number are correct.
Checking the Tablet Network Settings
The tablet interface utilizes an application called TouchOSC, this can be downloaded from the Apple Store or Google Play, and a custom TouchOSC layout must be obtained, this can be found in the software directory of the Media Server. Refer to the documentation provided with TouchOSC to find out how to synchronise the layout with the tablet.
Once TouchOSC is setup with the correct layout, the following procedure is used to connect the tablet to Igloo Control: -
Connect the tablet to the same local area network as the Media Server
Start TouchOSC on the tablet
When TouchOSC opens, a menu should appear. Tap the button which says OSC, under the connections heading. A menu, similar to the screenshot shown below, should appear
Enter the IP address of the media server you established earlier, e.g. 192.168.0.100 in the Host field
Set the Port (outgoing) field to 9004
Set the Port (incoming) field to 9003
Return to the main page in the menu and press Done
