Live capture camera to 3D Particles and AirServer compositing with 'Syphon Receiver'



  • Thankfully the universe has artists.

    Awesome fun making this clip captured and rendered in realtime with Isadora 2.5 (prerelease). The Isadora patch progressively captured 2 sec of video, applied threshold and blur, then lined up a row x10 of the captured clips to be accessed by the 3D Particles. The video capture (from an infrared camera) continued to update the assets in the video media bin via the 'Capture Camera to Disk' node, so the particles continued to be 'live'. 'Data Array' linked to 'Keyboard Watcher' triggered the changing parameters of the 3D Particles.

    On another note
    I had an opportunity to revisit [AirServer](https://www.airserver.com/) with the 'Syphon Receiver' within Isadora. It has been around for a while and AirServer's implementation of Syphon is pretty good. I can see potential for Isadora to embed support for AirPlay. If you are not familiar with the potential of using AirServer on the Mac platform below are my notes and here is a link to the [screen capture of the test](https://flashstream1.jcu.edu.au/camrelay/Russell_Milledge/Syphon_AirServer_demo/Syphon_AirServer_demo_-_20160919_170105_7.html)

    If you have a few Macs around with Isadora projects loaded you can composite their output via Airplay/AirServer/Isadora/Syphon Receiver. I realised 2 x VJ Systems to a 3rd control system. I also managed combinations of iOS devices (a couple of iPhones and iPad). Using AirServer and Syphon to transfer the Isadora Stage video presentation from the 2 MBP source systems into a control system for additional compositing and motion effects then outputting the third combined stage video presentation.
    3 x MBP | OSX 11.10.5 | Isadora 2.2.2 usb & 2.4.5b09 usb | wireless network 5G | AirServer 7.0.1
    Set up the control system with a dual monitor.
    Create an Isadora patch on the control system to receive the 2 x syphon streams and place the patch interface on the second monitor.
    Use OSX System Preferences/Displays on the source systems to activate AirPlay Displays send to the control system running AirServer. AirServer takes over the screen on the control system : remedy, use OSX System Preferences/Mission Control/Hot Corners to activate a screen corner to display Application Windows (I have contacted AirStream about the implication of blacking out the desktop).
    Start the Isadora patch on each of the source systems and output the stage.
    By now the Syphon Receivers in the control system Isadora patch will offer the two incoming video streams at the nodes ‘Server’ inputs.
    Composite the streams within the control patch to output as required.
    One recurring bug : When using 'esc' key on the control system in AirServer (to get back the desktop) one of the streams was immediately terminated and the Isadora patch on the source computer crashed.
    Not sure if the AirServer implementation is going to be comfortable in a show/professional situation, but with a few software tweaks by the developers AirServer would be very useful for multi-system compositing in Isadora.
    cheers
