Camera topdown view

Troubleshooting General Help
1

I wonder how to set up a topdown view.

I've tried:


cam.setFrustumPerspective(45.0f, (float) settings.getWidth() / (float) settings.getHeight(), 1, 1000);
      Vector3f location = new Vector3f(0.0f, 150.0f, 200.0f);
      Quaternion rot = new Quaternion();
      rot.fromAngleAxis(FastMath.DEG_TO_RAD*180, Vector3f.UNIT_Y);
      cam.setFrame(location,rot);
      cam.update();


Doesn't matter how high the first parameter is set. The angle of the camera will not change. I also tried "fromAngleNormalAxis" doesn't help anyhow.

Next thing I've tried is :


cam.setFrustumPerspective(45.0f, (float) settings.getWidth() / (float) settings.getHeight(), 1, 1000);
      Vector3f location = new Vector3f(0.0f, 150.0f, 200.0f);
      Vector3f left = new Vector3f(-1.0f, 0.0f, 0.0f);
      Vector3f up = new Vector3f(0.0f, 1.0f, 0.0f);
      Vector3f direction = new Vector3f(0.0f, -2.0f, -1.0f);
      cam.setFrame(location, left, up, direction);
      cam.update();


The direction vector sould be the value which affects the angle of the camera, right? If I change the y value of the direction vector, the only thing what happens is, the whole display deforms a bit but the cameras angle is unaffected.

Could somebody help me?

Thanks and regards

Perhaps you could try creating a cam node and setting the camera on that?

Then you could rotate the cam node.

Oh crap, I've forgotten that. Thanks for the help. :slight_smile:
