resize

public void resize(float worldWidth,
          float worldHeight,
          float screenScale)

Called when the screen is resized, or when the world renderer is first created. Resizes the camera to adjust to the new aspect ratio. Note that the parameters specify the new width and height that the camera should have. Third parameter specifies a screen scale. This should be the factor the view frustum had to be stretched to fit the target device. The level's line thickness is multiplied by this factor to compensate for a larger or smaller screen.
