Kinect Particle Simple Open Ni

phaidon

Hello I found this code in open processing and i want to modify it to draw same particles in kinect user map,i have tried different methods,does anyone have any idea?And also does any know what the float det() is in the end?Thanks in advance

The original code ` /**

Use mouse to control it. Use left button to organize it's movement, right to organize it's position. Scroll to change it's calmness

*/

int n = 2000; // number of cells
float bd = 30; // base line length
float sp = 0.001; // rotation speed step
float sl = .9; // slow down rate

float bcg_color = 0;

Cell[] all = new Cell[n];

public class Cell {

  float x, y;
  float x_start, y_start;
  float s = 0; // spin velocity
  float c = 0; // current angle

  Cell(float x, float y) {
    this.x=x;
    this.y=y;
    this.x_start = x;
    this.y_start = y;
  }

  void sense() {
    if (pmouseX != 0 || pmouseY != 0)
      s += log(sp * .5 * abs(det(x, y, pmouseX, pmouseY, mouseX, mouseY)) / (dist(x, y, mouseX, mouseY) + 1) + 1);
    s *= sl + 0.01;
    c += s;
    float d = bd * s + .001;
    stroke((50 + abs(d)*5));
    line(x, y, x + d * cos(c), y + d * sin(c));
    x = (x + (.5 * d * cos(c)));
    y = (y + (.5 * d * sin(c)));
  }

  void reset() {
    x = x_start;
    y = y_start;

  int h = min(height - 300, 400);
  for (int i = 0; i < n; i++) {
    // float xx = random(w) + (width - w)/2;
    // float yy = random(h) + (height - h)/2);
    all[i] = new Cell(random(w) + (width - w)/2, random(h) + (height - h)/2);

  bcg_color = map(sl, .85, .99, 40, 0);

    all[i].sense();
}

  float c = random(0, 2*PI);
  if (mouseButton == LEFT) {
    for (int i=0; i<n; i++)
      all[i].c = c;

      all[i].reset();

My code ` class Cell {

  float det(float x1, float y1, float x2, float y2, float x3, float y3) {
