There is some cool improvements not reflected in this video.
but here: vimeo.com/14119612
this video shows a prototype version of a project called "vinyl+".
the data (rotation speed, needle position) i get out of a white timecode vinyl is not only used to control sound but also animations which are projected directly onto the vinyl itself.
in this short demo i define objects which trigger samples and change their appearance when "hit" by the needle.
the timecode's speed data controls rotation, colors and sample pitch.
by reading out the timecode's needle position the computer can tell exactly when a virtual object is being hit by the turntables needle.
please note that there is no camera tracking involved!
