Examples of com.ardor3d.renderer.Camera.lookAt()

com.ardor3d.renderer.Camera.lookAt()
A convenience method for auto-setting the frame based on a world position the user desires the camera to look at. It points the camera towards the given position using the difference between that position and the current camera location as a direction vector and the general worldUpVector to compute up and left camera vectors. @param pos where to look at in terms of world coordinates @param worldUpVector a normalized vector indicating the up direction of the world. (often {@link Vector3#UNIT_Y} or{@link Vector3#UNIT_Z})
