LightBridge

LightBridge is a MaxMSP app that uses Mira4Web to generate a simple-to-use GUI to control the lighting inside the IASpace. It allows control over the ceiling and gallery lights, such as Ceiling Lights (normal room lights), Arri Fresnels (spotlights), Arri Skypanels (if installed) and Moving Lights (also called moving heads, if installed).

In order to make it work three conditions have to be met:

  • The main switch of the room is set to off (there are three such switches at each door).
  • The ETC app and the LightBridge app are running on the machines IO / MAYA.
  • You can access the IASpace LAN via cable or WiFi.

If conditions meet, you simply have to click here (this link only works if you are connected to the IAS network), and you will have access to the GUI.

The main tab of the LightBridge GUI is RoomLights.

The Roomlights interface allows you to set all the ceiling lights individually, by using the blue sliders on the top, you can control the overall intensity of the selected activated lights.

The yellow sliders, on the bottom, override all the individual settings. Once these sliders are set to 0, the individual settings take precedence.

Each light can be addressed individually or in groups by using its ID number. Each light has an individual ID, visible as a small number on the corners of the buttons.

Presets allow for storing specific settings (so-called sets) for recall.

This interface lets you switch on the control of other kinds of lights, like Moving Lights and Arri Fresnels (spotlights), Arri Skypanels, etc. If you enable extra lights, you can use the ‘x’ to choose whether these lights should be controllable via recalls of presets. This lets you control the lights with the presets and other live data from your preferred show software by sending OSC (see OSC-messages below for instructions).

If you want to store the current set, first press the green button ‘on recall’ so it turns red and reads ‘store’, and then select the preset button you want to store the set in.

Once you are happy with your presets, you can press ‘save’ to store the presets for future use.

To use fade times between the different sets, you can enable ‘fade’ and select or enter a suitable time in seconds.

With ‘label’, you can select a suitable description for the set. The label has no other function than to give information about the specific set.

ArriFresnels are 6 rows of 3 spots each. To enable their control, you need to toggle them via the button in the Presets interface.

The upper slider overrides the same settings for all the Arri Fresnel lights.

There are two colour modes, one of which allows setting RGB values plus a white addition, and the other mode allows setting the colour temperature.

LightBridge is developed on this GitLab repo: https://gitlab.zhdk.ch/iaspace/infrastructure/iaserver/lightbridge

The compiled standalone app can be found inside the IAS NAS under: 08_software > 0_server_only

The LightBridge app is to be started in conjunction with the ETC app. Three scheduled tasks are set on the IO / Maya pc to start ETC and LightBridge in the correct sequence and can be found inside: 08_software > 0_server_only>TaskScheduler

If you need to restart the apps manually (in the IO / MAYA pc), first launch the ETC app as primary, then launch the LightBridge app (the apps’ icons are visible on the taskbar).

ETC app interface.

It is possible to remotely control the LightBridge by sending OSC messages to the IP address of the machine the LightBridge currently runs (most likely inside the IO pc) and on port 1234:

A set of examples to interactively control the lights using Max.

This example showcases how to send rigidbody information from the mocap system to the LightBrige to control the Moving Lights.
