thanks sorted that now but now I’m having a problem with undefined references

#226

Hmm not sure but it looks like you might have gone from including them twice to not including them at all.

I’m not used to the compiler output (is it Codeblocks?) but it looks like a linker error meaning that the compiler has found the .h files to ofxOpenNI but during its compile process it didn’t work its way through all of ofxOpenNI’s .cpp files. Are these included in the project (once)?

#227

Im such a dumbass. Amazing thanks so much man. owe you big time :smiley:

#228

Hi guys somethings happened now wherein codeblocks now freezes every time the example is initialized

Problems with installing ofxOpenNI
#230

@oceanmachine89,
you’re not linking the libraries correctly.

Problems with installing ofxOpenNI
#231

Yeah I got that thanks again

#232

Hi guys working on a project and just wondering what the best way would be to control an obj file within a virtual environment using the Kinect. I was thinking about using the kinect as possibly using the mouse cursor? Does anyone have any experience with this sort of thing?

#233

oceanmachine89,
you can use an ofEasyCam and bind the kinect skeleton data to the camera movement parameters. and use hand gestures to switch between the different camera modes.
goodluck

#234

Is that not just rotating the camera around the 3D object though, I’m looking to move the objects along the x,y and z axis parameters

#235

you can make your own custom class that inherits from ofNode and loads and draws the 3d object. the ofNode class has all the necessary functions to move and rotate over 3d space. in terms of picking the object, take a look to the example 3d/pointPickingExample.

On the other hand, I think that there might be an addon for what you need. take a look at ofxaddons.com

good luck.

#236

been playing around with this code

  
glTranslatef(ofGetWidth()/2,ofGetHeight()/1.15,0);  
       glRotatef(-qMouseY,1,0,0);  
        glRotatef(qMouseX,0,1,0);  
      teaModel.setRotation(0, 90, 1, 0, 0);  
    teaModel.setRotation(1, 270, 0, 0, 1);  
        glTranslatef(-ofGetWidth()/2,-ofGetHeight()/1.15,0);  
        teaModel.draw();  
         glPopMatrix();  
         glPushMatrix();  
        glTranslatef(ofGetWidth()/2,ofGetHeight()/1.25,0);  
        glRotatef(-pMouseY,1,0,0);  
        glRotatef(pMouseX,0,1,0);  
      teapotModel.setRotation(0, 90, 1, 0, 0);  
    teapotModel.setRotation(1, 270, 0, 0, 1);  
        glTranslatef(-ofGetWidth()/2,-ofGetHeight()/1.25,0);  
        teapotModel.draw();  
         glPopMatrix();  
         glPushMatrix();  
        glTranslatef(ofGetWidth()/2,ofGetHeight()/1.25,0);  
        glRotatef(-rMouseY,1,0,0);  
        glRotatef(rMouseX,0,1,0);  
      plateModel.setRotation(0, 90, 1, 0, 0);  
    plateModel.setRotation(1, 270, 0, 0, 1);  
        glTranslatef(-ofGetWidth()/2,-ofGetHeight()/1.25,0);  
        plateModel.draw();  
         glPopMatrix();  
         glPushMatrix();  
        glTranslatef(ofGetWidth()/2,ofGetHeight()/1.25,0);  
        //tumble according to mouse  
        glRotatef(-sMouseY,1,0,0);  
        glRotatef(sMouseX,0,1,0);  
      spoonModel.setRotation(0, 90, 1, 0, 0);  
    spoonModel.setRotation(1, 270, 0, 0, 1);  
        glTranslatef(-ofGetWidth()/2,-ofGetHeight()/1.25,0);  
        spoonModel.draw();  
         glPopMatrix();  
    glPopMatrix();

, it seems to work in terms of mouse control , would I need to modify it much for skeleton control

#237

though this is more stable by the looks of it and saves space with reduced code

  
cam.begin();  
	ofRotateX(ofRadToDeg(.5));  
	ofRotateY(ofRadToDeg(-.5));  
  
  
  
  
  
	ofPushMatrix();  
	ofTranslate(0,0,20);  
	ofFill();  
	ofNoFill();  
	ofSetColor(0);  
    teapotModel.draw();  
	ofPopMatrix();  
	cam.end();
#238

@oceanmachine89
in the last code chunk, the cam is an ofCamera or an easyCam? the difference between both is that easyCam inherits from ofCamera, and easyCam adds mouse control over ofCam.

You could also make some ofNode objects, one for each 3d model you have and apply each ofNode transformation to the 3d model quite easily. This way you can transform each model independently later.
also, it might be simpler to have the models and ofNodes stored in vectors, so you just use a for loop to draw them all, as the transformations all seemed to be the same.

  
  
on testApp.h  
vector<whateverclass are the models>models;  
vector<ofNode>modelTrans;  
void testApp::setup(){    
//add the models to the vectors. repeat for each model to add.  
modelclass tempModel;  
tempModel.load(...);  
models.push_back(tempModel);  
ofNode tempNode;  
tempNode.setRotation(....);//o whichever initial transformation  
modelTrans(tempNode);  
  
//here you set the transformatios as you want, but have the ability to change later programatically or interactively.  
   for(int i = 0; i<models.size(); i++){// here I'm considering that models and modelTrans are the same size  
modelTrans[i].setRotation(0, 90, 1, 0, 0);    
modelTrans[i].setRotation(1, 270, 0, 0, 1);    
}  
}  
void testApp::draw(){      
cam.begin();    
        ofPushMatrix();  
      ofTranslate(0,0,20);    
      ofNoFill();    
        ofSetColor(0);    
        for(int i = 0; i<models.size(); i++){// here I'm considering that models and modelTrans are the same size  
modelTrans[i].transformGL();  
        models[i].draw();  
modelTrans[i].restoreTransformGL();  
}  
      ofPopMatrix();    
      cam.end();    
}

hope it helps
best!

not sure if this is correct

modelTrans[i].setRotation(0, 90, 1, 0, 0);  
modelTrans[i].setRotation(1, 270, 0, 0, 1);  
}
#240

would ofNode include ofeasycam? is modeltrans a generic naming convention?

#241

im not sure if line 28 is correct for initializing the vector. If it is then it looks fine.

  
modelTrans(tempNode);

no, ofNode doesn’t include easyCam. Its the other way round, easycam inherits from ofNode.
I was discussing some time ago with elliotwoods about having an interactive ofNode, yet we were having trouble about inherintace stuff. I don’t know if he solved it, he might. take a look at his github as he has some really nice 3d related addons and stuff.

to interact with the models that I have created ?

#244

for the modelTrans vector initialize like this

  
  
  for(int i = 0; i<models.size(); i++){// here I'm considering that models and modelTrans are the same size    
ofNode  tempNode;    
modelTrans.push_back(tempNode);    
  
modelTrans.back().setRotation(0, 90, 1, 0, 0);    
modelTrans.back().setRotation(1, 270, 0, 0, 1);    
}

to use the code yo posted, first, replace the part that you posted before.
then to make the models interact with the openni data you first need to get the openNI data that you want to use. I guess that hands. use the code below to get hands.

  
  
ofVec3f l, r;  
for(int i = 0; i < openNIDevice.getNumTrackedUsers(); i++){  
            ofxOpenNIUser & usr = openNIDevice.getTrackedUser(i);          
            ofxOpenNIJoint left = usr.getJoint(JOINT_LEFT_HAND);  
            ofxOpenNIJoint right = usr.getJoint(JOINT_RIGHT_HAND);  
            if (left.isFound()) {  
                l.set(left.getProjectivePosition());//this will give the hand position in the projected image.  
                //l.set(left.getWorldPosition());//this will give you the position in 3dspace  
            }  
            if (right.isFound()) {  
                r.set(right.getProjectivePosition());  
            }

if you use the hands projective position you can interpret that data just like it was a mouse.
once you have hands you must have some sort of way to select the object you want to interact with. Maybe using a push gesture. Also check to point selection example to sort out whether the hand is over the object.
to interact with the object use the ofnode method, like rotate, translate or whaterver you like.

best!
