agenda vs siggraph.

Just wanted to mention – Agenda Circling Forth got shown in the Live Realtime Demos show at Siggraph 2010!

This show was strictly speaking for interactive pieces only, and ours was a realtime non-interactive demo. So I did some work to make it interactive via the use of a webcam – basically you can wave your hands around in front of the camera and it uses optical flow to calculate a motion buffer, which is used to manipulate the velocities of the particles, the fluid effects and the intensity of some of the post processing. It worked out quite nicely actually. I might have to make an exe available at some point..

I wasn’t able to attend in person so my friend Steve McAuley kindly presented it at the show. Unfortunately there were some technical difficulties at the show and when they attached a webcam to the PC it made it really unstable, so they ended up showing the non-interactive version. Still, the work on interactivity isn’t wasted – I’m sure it’ll be useful for other projects in future.

Many thanks to the organisers and to Steve for doing the business over there. Hopefully we’ll be able to do this again in future.

Next up: this..


  1. Lovely stuff. I’d definitely be interested in an exe of the interactive version, if you had time.

  2. So that’s the webcam option in the config dialog of ceasefire ! 🙂

    Does it work with ceasefire party version too ?

    • It has to be enabled in the project before export, but if it was enabled it would work, yes.. 🙂

  3. Yeah, it was definitely standing out from the crowd. I mean GoW and all the traditional demos from HW vendors were cool, but your piece was actually a great example of the marriage between the art and the technology, which can be viewed irrespectively of the medium it is presented within. It would be great to see more scene productions reaching out for the wider audiences. Jury member (who was introducing the presenters) mentioned that they were all blown away by this demo. Congrats for getting into the compo and kicking some asses!
    BTW I hope you win the arm wrestling compo next year 😉
