示例1: setupFirstPersonView
import gov.nasa.worldwind.view.orbit.OrbitView; //导入方法依赖的package包/类
/**
* Setup the view to a first person mode (zoom = 0)
*
* @param view the orbit view to set into a first person view.
*/

// Center pos at eye pos
Position centerPosition = wwd.getModel().getGlobe().computePositionFromPoint(eyePoint);
// Compute pitch and heading relative to center position
