I used helicopter-developed a 3D environment you can navigate the viewport of the flying objects the user. Implemented the effects are alive to the user is traveling block on the helicopter.
We propose a digital elevation model and an integrated digital data algorithm for orthophotos as the base algorithm for our approach to construct a realistic 3D terrain scene. A new technique is used with the aid of render a texture and display head to generate the navigation panel. In the simulation flight, in order to eliminate the flight "jump", the multidimensional linear interpolation method is used to dynamically and constantly adjust the camera parameters. Meanwhile, based on the principle of scanning laser scanning, we draw pseudo color figures by scanning the topography in different directions according to the real-time flight status. The results of the simulation demonstrate that the proposed algorithm is prospective for applications and the method can improve the effect and improve the dynamic interaction during the flight in real time.
