"context.enableScene() does not exist" -- Troubles with SimpleOpenNi and Processing

[Arnaud Perrillat]

Hello, im' trying to make an app with processing using kinect, and SimpleOpenNi. I tried to follow this tutorial http://www.creativeapplications.net/processing/kinect-physics-tutorial-for-processing/ , but i'm stuck at the very beginning : when i launch the first script processing returns me this error : "The function enableScene() does not exist" Also, the function sceneImage() doen't work.

I installed KinectSDK, OpenNi, NiTe, SimpleOpenNi lib, tried on 3 differents versions of processing (1.5.1, 2.0.1 x86, 2.0.2 x64) with win7&win8. I really can't find any solution on the web, if someone have some any clue, i'd be glad ! Thanks !

in the new version the method enableScene() was changed in enableUser()

[Arnaud Perrillat]

Ok, so userImage();

But i only want get user depth image, not background ! Because if userImage draw, the background also draw...

Have any solution for get exact user depth ?

Thank you

[Matteo Lupetti]

Try to use userMap()

[bsq]

Thank you so much ! 

I will try this ! :3

[bsq]

So userMap() is array ! NOT PImage !!! Can not draw this with userMap();

[Matteo Lupetti]

it is the map of the user image, you can copy the information of the array in a PImage of the same size.
for reference look here http://processing.org/reference/pixels.html

[bsq]

Thank you ! My mistake ! Easy to get this picture !

Hi so I changed userImage to userMap and now i get "cannot convert from int to PImage". Do you know how to solve this? What code to enter?

[Ewelina Bakała]

try this, the code draws detected users in red and the background in black

import SimpleOpenNI.*;

SimpleOpenNI  context;

PImage img;

int irW,irH;

void setup()

{

  context = new SimpleOpenNI(this);

  context.enableDepth();

  context.enableUser();

  if(context.isInit() == false)

  {

     println("Can't init SimpleOpenNI, maybe the camera is not connected!"); 

     exit();

     return;  

  }

  size(640, 480);

  img = new PImage(irW,irH); 

  img.loadPixels();

}

void draw()

{

  context.update();

  int[] u = context.userMap();

  for(int i =0;i<u.length;i++){

    if(u[i]==0){

      img.pixels[i] = color(0);

    }

    else  {

      img.pixels[i] = color(255,0,0);

    }

  }

   

  img.updatePixels(); 

  image(img, 0, 0);
