Hi

I need to set up a file so when a person enters a installation space the volume of an audio track will increase as they walk towards a specific point in the room:

eg. when you are standing at X: 3, Z: 2 (from the kinects perspective) the volume of the track will be 100% , the volume falls off from that position radially as the person moves away from that point.

Getting this to work with one coordinate is easy enough, I'm just a bit stuck when you add the 2nd coordinate into the equation.

Thanks
