ofxOpenNI drawMask() and drawPointCloud don't work

#1

I’m using OpenNI version 1.5.4.0 and NITE version 1.5.2.21 and I’m on Ubuntu 12.04.
Still using OF 0.8.x
gameoverhack master branch

Most of the parts work, except for one: I can’t see the user masks.
The native OpenNI examples work: I can see user outlines in them. But from OpenFrameworks, I can’t seem to get a user mask.

For each user in my OpenFrameworks code, I can do this:

// "user" is an object returned from ofxOpenNI::getTrackedUser

// This actually displays a skeleton:
user.drawSkeleton();
// These two do nothing:
user.drawMask();
user.drawPointCloud();

I tryed this also, but same result:

void testApp::setup() {
    //ofBackground(0,0,0);
    ofSetLogLevel(OF_LOG_VERBOSE);
    openNIDevice.setup();

    openNIDevice.addDepthGenerator();
    openNIDevice.addUserGenerator();
    ofSetFrameRate(15);
   
    openNIDevice.addImageGenerator();

    openNIDevice.setRegister(true);
    openNIDevice.setMirror(true);
    openNIDevice.setMaxUsers(2);
    openNIDevice.setMaxNumUsers(2);
    openNIDevice.setMaxUsersVis(2);

    //openNIDevice.setSkeletonProfile(XN_SKEL_PROFILE_NONE);
    user = new ofxOpenNIUser();

    (*user).setUseMaskTexture(true);
    (*user).setUseMaskPixels(true);
    (*user).setMaskPixelFormat(OF_PIXELS_RGB);
    (*user).setUsePointCloud(true);
    (*user).setPointCloudDrawSize(2);
    (*user).setPointCloudResolution(2);
    openNIDevice.setBaseUserClass(*user);

where user is defined in the .h file as ofxOpenNI *user;

In the update I do the following

void testApp::update()
{
   openNIDevice.update();


   openNIDevice.setMaxUsersVis(2);
   .....//nothing special
}

draw:

void testApp::draw(){

// use a blend mode so we can see 'through' the mask(s)
ofEnableBlendMode(OF_BLENDMODE_ALPHA);



//openNIDevice.drawDepth(0, 0);
//openNIDevice.drawImage(640, 0);


int numUsers = openNIDevice.getNumTrackedUsers();

for (int i = 0; i < numUsers; i++){

    // get a reference to this user

    ofxOpenNIUser & user2 = openNIDevice.getTrackedUser(i);
    user = static_cast<ofxOpenNIUser*>(&user2);

    // draw the mask texture for this user
    user->drawMask();
}

 ofDisableBlendMode();

}

Thanks so much in advance

#2

I tryed the UserandCloudSimple example, it works like a charm, but if I run the UserAndCloudMedium it freezes like my example. The last example use the drawMask() method.

The error is as follows:

[error]: ofxOpenNIDevice[0]: g_DepthMD.XRes() 640 g_ImageD.XRes() 640

I handle to avoid the error by doing the following within draw(), however, nothing is displayed.

        ofxOpenNIUser & user2 = openNIDevice.getTrackedUser(i);
        user2.setMaskPixelFormat(OF_PIXELS_MONO);
        
        // draw the mask texture for this user
        user2.drawMask();

I am clueless at all, any hint? Thanks
