ARHeadtracker

ARHeadtracker is a class that uses a LocalClient to receive data from the ARHeadtracker command

line tool via OSC (dont forget to start the tool in order to receive data...)

An instance implements the kr method and delivers [elevation, atzimuth, roll]

a = ARHeadtracker.new;

// look straight forward to calibrate the system

a.reset;

// create the virtual room

p = ProxySpace.push;

// simple test with sinus freq controled by azimuth

~test = { SinOsc.ar(200 + (a.kr[1] * 100), 0, 0.2) };

~test.play;

~test.clear;

// more complex example as headtracker in a virtual environment

VirtualRoom.revTime = 1;

VirtualRoom.revGain = 0.1;

VirtualRoom.hfDamping = 1;

VirtualRoom.init;

VirtualRoom.start;

{ VirtualRoom.ar }.play;

// position the listener in the middle of the room and assign the 

// head tracker data to the orientation of the listener 

~listener = { | x=2.5, y=4, z=2.5, o=0| [x,y,z, a.kr[1]] };

v = VirtualRoom.new;

v.listener = ~listener; 

v.room = [0, 0, 0, 5, 8, 5];

v.refGain = 1;

v.play;

// adding a source to the scene (slightly right off)

~noisy = { EnvGen.kr(Env.adsr, Impulse.kr(3)) * PinkNoise.ar(1) };

~noisyPos = { | x=3.5, y=3, z=2.5 | [x,y,z] };

v.addSource( ~noisy, "test1", ~noisyPos);

v.removeSource("test1");

// play and stop the virtual room

v.play;

v.stop;

// stop the rendering engine

VirtualRoom.stop;

p.pop;
