I have been looking into interaction of crowds with video and have just discovered real-time animation. Animata is "an open source real-time animation software, designed to create animations, interactive background projections for concerts, theatre and dance performances". I followed the first tutorial and found it very straight forward - here's the result:
You can control the animation by sending position information for joints, bone length etc. via Open Sound Control (OSC) messages. OSC appears to be a standard messaging language for music/performance equipment similar to MIDI but richer and better. Quartz Composer has OSC plugins to drive animations and other sensors can be used to including your own body using a webcam and Eyesweb. The possibilities!! I need to buy a projector and make an interactive cartoon puppet. I wonder how a could create something I saw in a Leicester Square cinema a bit like this interactive basketball projection from Po-Motion.
For a first try I don't think it's that bad. I limited the number of triangles created to around 30 and a created the vertices a bit shoddily too which lead to the funny crease in the bicep when the arm curls. More triangles/better vertices would make that much better.
