I don't get the question. What does the orientation has to do with the game's logic?

rephrase.

I want to rotate the orientation of scene from portrait to landscape. how can i do this?

Hi,

I want to rotate the orientation of scene from portrait to landscape without the logic of game to be affected.

How can i do this?

Hi!
I have the same problem. I want to rotate a car from the old position to the next.
I have the following code:

SimpleVector carOldPosition = car.getTransformedCenter();   
SimpleVector tr = new SimpleVector(-locO.x + loc.x,  -locO.y + loc.y, -3.059705E-7f);
car.translate(tr);
SimpleVector directionVector = new SimpleVector(
                  carOldPosition.x - car.getTransformedCenter().x
              ,   carOldPosition.y -  car.getTransformedCenter().y
              ,   carOldPosition.z -  car.getTransformedCenter().z);

Matrix rotationMatrix = directionVector.getRotationMatrix();
car.setRotationMatrix(rotationMatrix);
car.rotateX((float) Math.PI/2f);
car.rotateMesh();


Is not the desired behavior

Thanks!
This code with some adjustment at some values  works perfectly.

private void moveCamera() {
      SimpleVector oldCamPos=camera.getPosition();
      SimpleVector oldestCamPos=new SimpleVector(oldCamPos);
      oldCamPos.scalarMul(9f);

      SimpleVector carCenter=car.getTransformedCenter();
      SimpleVector camPos=new SimpleVector(carCenter);
      SimpleVector zOffset=car.getZAxis();
      SimpleVector yOffset=new SimpleVector(0, -100, 0);
      zOffset.scalarMul(-250f);

      camPos.add(zOffset);
      camPos.add(yOffset);

      camPos.add(oldCamPos);
      camPos.scalarMul(0.1f);

      SimpleVector delta=camPos.calcSub(oldestCamPos);
      float len=delta.length();

      if (len!=0) {
         /**
          * Do a collision detection between the camera and the ground to prevent the camera from
          * moving into the ground.
          */
         theWorld.checkCameraCollisionEllipsoid(delta.normalize(), new SimpleVector(20, 20, 20), len, 3);
      }

      /**
       * And finally: Look at the car
       */
      camera.lookAt(car.getTransformedCenter());
   }

Hi!

I want to create a track race and i don't know how to set my camera to follow the position of car.
