Using saito obj loader, I made an object called 'shuttle'.

Code:

import processing.opengl.*;
import javax.media.opengl.*;

OBJModel model;
 
class Shuttle
{
  Shuttle(PApplet app, String name)
  {
    model = new OBJModel(app, name);
  }
 
  void drawShuttle(GL gl)
  {
    pushMatrix();
    translate(2016, 2016, 1200);
    scale(50);
    model.drawMode(POLYGON);
    model.draw();
    popMatrix();
  }
} 

In the main draw function:

Code:

  GL gl = pgl.beginGL();
  cameraControl(gl);
  shuttle.drawShuttle(gl);
  pgl.endGL(); 

Using the camera() function I move the camera around.

Code:

  if (keyPressed)
  {
    if ( key == 'w' )
      camY -= cameraSpeed;        
    if ( key == 's' )
      camY += cameraSpeed;        
    if ( key == 'a' )
      camX -= cameraSpeed;
    if ( key == 'd' )
      camX += cameraSpeed;
    if ( key == 'q' )
      camZ -= cameraSpeed*2.5;
    if ( key == 'e' )
      camZ += cameraSpeed*2.5;
  } 

The problem is that when I move the camera around, the object moves in the opposite direction of the camera. I have also drawn a box() which doesn't move. And if I zoom out far enough the object moves behind the box.

Why?
