KINECT Skeleton Tracking To MAX/MSP

You should be more familiar with this than before.

OPEN your “Skeleton3D” again

Since we will send data to MAX/MSP with OSC

OSC = Open Sound Control OSC is the acronym for Open Sound Control, a network protocol developed at cnmat, UC Berkeley. Open Sound Control is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is optimized for modern networking technology and has been used in many application areas.

Anyway, we need a Library: oscP5

Download through here.

And put it to your Processing/ modes/Java/ libraries Or C:\Users\archgary\Documents\Processing\lib raries (Will not repeat this part.)

import oscP5.*; import netP5.*;

Import Libraries

import SimpleOpenNI.*; import peasy.test.*; import peasy.org.apache.commons.math.*; import peasy.*; import peasy.org.apache.commons.math.geometry.*; import processing.opengl.*; SimpleOpenNI context; PeasyCam cam; int boundSize = 2400;

Create an oscP5 object. OscP5 oscP5; Create an Network Address. NetAddress myRemoteLocation; OscMessage myMessage = new OscMessage(""); Create a Message for input data. PVector PVector PVector PVector color[]

bodyCenter = new PVector(); bodyDir = new PVector(); com = new PVector(); com2d = new PVector(); userClr = new color[]{ color(255,0,0), color(0,255,0), color(0,0,255), color(255,255,0), color(255,0,255), color(0,255,255) };

Something like this. ***before setup();

void setup(){ size(1024,768,P3D); context = new SimpleOpenNI(this); if(context.isInit() == false) { println("Can't init SimpleOpenNI, maybe the camera is not connected!"); exit(); return; } // disable mirror context.setMirror(false); // enable depthMap generation context.enableDepth(); // enable skeleton generation for all joints context.enableUser(); cam = new PeasyCam(this, 0, 0, 1000, 4000);

//start oscP5, telling it to listen for incoming messages at port 5001 */ oscP5 = new OscP5(this,5001); Set up a PORT. // set the remote location to be the localhost on port 5001 myRemoteLocation = new NetAddress("127.0.0.1",5001); stroke(255,255,255); smooth();

Stay with this for internal communication with MAX/MSP.

} IF YOU WAN TO SEND TO OTHER DEVICE IN THE NETWORK HERE ARE THE SETTING YOU NEED TO MODIFY.

***draw();

Run it! But how we know it works?

Open a new Patcher

Add a new Object

More like Grasshopper as a visual coding

Click on the Object

Type in “udpreceiver 5001” Number match to the Port you send out.

Make another selection with â&#x20AC;&#x153;messageâ&#x20AC;?

And make the connection like this. (simply drag and pull)

Now back to Processing, And Run it.

Processing Code.

Processing Canvas

MAX/MSP

X Now they are talking.

Examples sending messages relating to the real-time 3D projection. (Might have minor changes)

In projection:

Point : Intersection of Lines. Line: Intersection of Planes.

EXAMPLEs: 2Points Also need to separate the Skeleton Message and Geometry Message

//start oscP5, telling it to listen for incoming messages at port 5001 */ oscP5 = new OscP5(this,5002); // set the remote location to be the localhost on port 5001 myRemoteLocation = new NetAddress("127.0.0.1",5002); stroke(255,255,255); smooth();

} First, I would like to set the skeleton message to â&#x20AC;&#x153;5002â&#x20AC;?

***setup();

import oscP5.*; import netP5.*;

Then, Mostly we are doing duplication.

import SimpleOpenNI.*; import peasy.test.*; import peasy.org.apache.commons.math.*; import peasy.*; import peasy.org.apache.commons.math.geometry.*; import processing.opengl.*; SimpleOpenNI context;

PeasyCam cam; int boundSize = 2400;

OscP5 oscP5; OscP5 oscP5_P; NetAddress myRemoteLocation; NetAddress myRemoteLocation_P; OscMessage myMessage = new OscMessage(""); OscMessage myMessage_P = new OscMessage(""); PVector PVector PVector PVector color[]

Something like this. ***before setup();

//start oscP5, telling it to listen for incoming messages at port 5001 */ oscP5 = new OscP5(this,5002); oscP5_P = new OscP5(this,5001); // set the remote location to be the localhost on port 5001 myRemoteLocation = new NetAddress("127.0.0.1",5002); myRemoteLocation_P = new NetAddress("127.0.0.1",5001); stroke(255,255,255); smooth();

} Remember to change the Address & Port to the one you will send.

***setup();

No need to worry about the message for skeleton which we have it already.

In this case, We are sending the coordination of our 2 hands.

// draw the center of mass if(context.getCoM(userList[i],com)) { stroke(100,255,0); strokeWeight(1); beginShape(LINES); vertex(com.x - 15,com.y,com.z); vertex(com.x + 15,com.y,com.z);

void draw(){ context.update(); background(0,0,0); pushMatrix(); translate(0, 0, boundSize/2); stroke(255, 0, 255); noFill(); box(boundSize); popMatrix();

vertex(com.x,com.y - 15,com.z); vertex(com.x,com.y + 15,com.z);

vertex(com.x,com.y,com.z - 15); vertex(com.x,com.y,com.z + 15); endShape(); //fill(0,255,100); //text(Integer.toString(userList[i]),com.x,com.y,com.z); } } // draw the kinect cam context.drawCamFrustum();

for(int i=0;i<userList.length;i++) { if(context.isTrackingSkeleton(userList[i])){ drawSkeleton(userList[i]);

Extract the Hands.

PVector BRh = new PVector(); context.getJointPositionSkeleton(userList[i], SimpleOpenNI.SKEL_RIGHT_HAND, BRh); PVector BLh = new PVector(); context.getJointPositionSkeleton(userList[i], SimpleOpenNI.SKEL_LEFT_HAND, BLh); stroke(0,255,0); strokeWeight(10); point(BLh.x,BLh.y,BLh.z); point(BRh.x,BRh.y,BRh.z);

Draw the Hands Draw line between hands

oscP5.send(myMessage, myRemoteLocation); //send the message out. myMessage.clear(); //clean the message once it send out.

oscP5.send(myMessage_P, myRemoteLocation_P); myMessage_P.clear();

strokeWeight(4); line(BLh.x,BLh.y,BLh.z,BRh.x,BRh.y,BRh.z);

myMessage_p.add(new float[] {BLh.x,BLh.y,BLh.z,BRh.x,BRh.y,BRh.z}); }

Put it in the myMessage_P

popMatrix();

Send the data out!

} ***draw();

Copy another set of it. Change the Port Number.
