A month ago, Bill Brock and I pitched our idea to develop an open source 3D web-based videoconferencing system for the Mozilla Ignite Challenge over Google chat. Will Barkis from Mozilla recorded and moderated the conversation and then sent it off to a panel of judges. The pitch was to receive a slice of $85,000 that was being doled out to the winners of the Challenge.
After some anticipation, we got word that we were among the winners. We would receive $10,000 in funding to support the development of our prototype. Our funding will cover travel expenses, accommodations, the purchasing of additional hardware and the development of the application itself.
We will also take on two more developers and have a hackathon closer to the end of the month. Over the span of four days we will iterate on our original code and release something more substantial. The Company Lab in Chattanooga has agreed to provide us with a venue to hack and a place to plug into the network. Both Bill and I are extremely excited to get back to hacking on Engage3D and to get back to playing with the gig network.
We will keep you updated on our Engage3D progress, stay tuned!

I am working with Bill Brock (a PhD student from Tennessee) to develop an open source 3D video conferencing system that we are calling engage3D. We are developing this application as part of Mozilla’s Ignite Challenge.
During the past few days, Bill and I made some major breakthroughs in terms of functionality. Bill sent me Kinect depth and color data via a server he wrote. We then managed to render that data in the browser (on my side) using WebGL. We are pretty excited about this since we have been hacking away for quite some time!
There has been significant drawbacks to developing this application over commodity internet, I managed to download over 8Gb of data in only one day while experimenting with the code. Hopefully, this will soon be able to be ported to the GENI resources in Chattanooga, TN for further prototyping and testing.
Even though we are still limited to a conventional internet connection, we want to do some research into data compression. Also, we have been struggling with calibrating the Kinect. This is also something we hope to resolve soon.
Reflections on Hackanooga 2012 September 19, 2012Posted by Andor Saga in Hackanooga, Kinect, point cloud.

This past weekend, I had the opportunity to participate in Hackanooga, a 48-hour hackathon in Chattanooga, Tennessee. The event was hosted by Mozilla and US Ignite with the purpose of encouraging and bringing together programmers, designers, and entrepreneurs to hack together demos that make use of Chattanooga’s gigabit network.
We only had two days to hack something together, so I wanted to make my goals simple and realistic. My plan was to set up a server on the gig network, upload dynamic point cloud data to the server and then stream the data back in real-time. In case I got that working, I wanted to try to avoid disk access altogether and stream the data from a Kinect and render it using WebGL.
Before the hacking began, anyone who wasn’t assigned a project had the chance to join one. I was surprised that several developers from the University of Tennessee at Chattanooga approached my table to hear more about my project. We quickly formed a group of four and dove right into setting up the server, editing config files, checking out the super-fast gig connection, and making sure our browsers supported WebGL. After a lot of frustration we finally managed to ‘stream’ the dynamic point cloud from the server. Although the data seemed to stream, it took a while to kick in on the client side. It was almost as if the files were being cached on the server before being sent over the wire. This is still something I need to investigate.
Once we had that working, we moved on to the Kinect. We created a c++ server that read the Kinect data and transferred that data to a node server via sockets. The node server then sent the data off to any client connections. My browser was one of the clients rendering the data, however, the rendered point clouds were a mess. One of the applications we wrote had a bug that we didn’t manage to fix in time ): Even though we didn’t manage to hammer out all the issues, I still had a lot of fun working with a team of developers.
Rumor has it that Hackanooga may become a yearly event. I’m already excited (:
