Make the animation to move with kinect

phiquit

Hello,

I am very new in Processing. I am using Processing 3.3. So I found this formula and I want to move the animation by tracking my movements from a Kinect instead of a mouse. I am using the new Kinect on a Mac. I can get information from kinect2 but I can't find a way to connect my movements with the animation. Can pls someone help me?

void setup () {
  size (500,500);
  noFill();
  stroke(255);
  strokeWeight(2);
}




void draw() {
  background(0);



  translate(width /2, height/2);

  beginShape();

  // add some vertices



  for (float theta = 0; theta <= 2 * PI; theta += 0.01) {

    float rad = r(theta,
    mouseX / 100.0, // a
    mouseY / 100.0, // b
    70, // m
    1, // n1
    2, // n2
    2 // n3
    ); 
    float x = rad * cos (theta) * 50;
    float y = rad * sin (theta) * 50;
    vertex (x, y);


  }

  endShape();


}


float r(float theta, float a, float b, float m, float n1, float n2, float n3) {
  return pow(pow (abs(cos(m * theta / 4.0)/a), n2 ) + 
    pow (abs(sin(m * theta / 4.0) /b), n3), -1.0 / n1) ; 

}

Please edit your post, select your code and hit ctrl+o to format your code. Make sure there is an empty line above and below your code

thanks. It looks better now :)

How do you want to connect this code with kinetic?

Also, check previous comments related to kinetic here: https://forum.processing.org/two/search?Search=kinetic

Hello, Thanks for your reply. I would like to make this animation to react with a performer's (body) on stage. Instead of using the mouse I would like to use the kinect. I insalled the open kinect library by shimman import org.openkinect.processing.*;

Here is the code I am using:

import org.openkinect.processing.*;

// Kinect Library object
Kinect2 kinect2;
PImage img;

void setup () {
  size (500,500);
  kinect2 = new Kinect2(this);
  kinect2.initDepth();
  kinect2.initDevice();
  noFill();
  stroke(255);
  strokeWeight(2);
}




void draw() {
  background(0);

  PImage img = kinect2.getDepthImage();
  image (img, 0, 0);

  translate(width /2, height/2);

  beginShape();

  // add some vertices



  for (float theta = 0; theta <= 2 * PI; theta += 0.01) {

    float rad = r(theta,
    mouseX / 100.0, // a
    mouseY / 100.0, // b
    70, // m
    1, // n1
    2, // n2
    2 // n3
    ); 
    float x = rad * cos (theta) * 50;
    float y = rad * sin (theta) * 50;
    vertex (x, y);


  }

  endShape();


}


float r(float theta, float a, float b, float m, float n1, float n2, float n3) {
  return pow(pow (abs(cos(m * theta / 4.0)/a), n2 ) + 
    pow (abs(sin(m * theta / 4.0) /b), n3), -1.0 / n1) ; 

}

Check this previous post as it could give you an idea of how to use the depth data: https://forum.processing.org/two/discussion/21412/kinect-projection-masking-array-out-of-bounds-error#latest

This is untested code below. What I do is I grab the depth value right at the center of the depth data (yes, only one pixel) and i used that to replace the effect of mouseX from your code.

Also search for other examples using https://forum.processing.org/two/search?Search=depthMap

Lastly, check Shiffman's videos on Kinetic: https://www.youtube.com/playlist?list=PLRqwX-V7Uu6ZMlWHdcy8hAGDy6IaoxUKf

import org.openkinect.processing.*;

// Kinect Library object
Kinect2 kinect2;
PImage img;

//distance in cm depth, adapt to room 
int distance = 1500;
int distance2 = 3000;

void setup () {
  size (500, 500);
  kinect2 = new Kinect2(this);
  kinect2.initDepth();
  kinect2.initDevice();
  noFill();
  stroke(255);
  strokeWeight(2);
}

void draw() {
  background(0);

  PImage img = kinect2.getDepthImage();
  image (img, 0, 0);

  kinect.update();
  int[] depthValues = kinect.depthMap(); //array, distances 

  translate(width /2, height/2);
  beginShape();

  int centerOfScreen= depthMapWidth/2.0+(depthMapWidth/2.0*depthMapWidth);
  int currentDepthValue = depthValues[centerOfScreen];
  float mappedVal=map(currentDepthValue,distance,distance2,0,width/100.0);

  // add some vertices
  for (float theta = 0; theta <= 2 * PI; theta += 0.01) {

    float rad = r(theta, 
      mappedVal, // a
      mouseY / 100.0, // b
      70, // m
      1, // n1
      2, // n2
      2 // n3
      ); 
    float x = rad * cos (theta) * 50;
    float y = rad * sin (theta) * 50;
    vertex (x, y);
  }

  endShape();
}


float r(float theta, float a, float b, float m, float n1, float n2, float n3) {
  return pow(pow (abs(cos(m * theta / 4.0)/a), n2 ) + 
    pow (abs(sin(m * theta / 4.0) /b), n3), -1.0 / n1) ;
}

Hello, Thank you very much for your help. I really really appreciate that. As you notice I am not that familiar with processing and this might be very easy to do if you are familiar with the code.

I am getting two errors on lines 27 and 28. Probably I need to change to kinect2. However, when I change to kinect2 I 've got another error on line 27 (the function update() does not exist ). when I change kinect.depthMap to kinect2.depthMap it says 'The Sunction'depthMap() does not exist.

I am writing kinect2 because I am using the new kinect. I will check as well the links you send me.

Thank you so much !!!

I will check the provided documentation and any previous post using kinetic2. You are right, lines 27 and 28 should be kinetic2. I copy this from a previous post and they could some bugs.
