First of all oscP5 and netP5 libraries are imported inside the sketch.In order to use OSC protocol we have to import those library. There are 3 messages received from Captury, they are x,y,z coordinates of the tracked person locations. | First of all oscP5 and netP5 libraries are imported inside the sketch.In order to use OSC protocol we have to import those library.
