Development of Key Functions for Flight Simulator

Abstract

© 2016 SERSC. A flight simulator is usually developed to verify the operations of aircraft and train the pilot through it. For this goal, it is necessary to include a variety of functions that work in real-time way. However, due to a huge volume of terrain data, graphic rendering speed becomes slow whenever additional computing processing is demanded. To address this problem, in this paper, we propose two techniques to speed up rendering speed for new flight simulator under our software architecture and module. Both hybrid cloud effect and adaptive culling scheme are proposed and implemented by OpenSceneGraph(OSG) library on Windows. Through diverse experimental results to verify their suitability, we demonstrate that acceptable rendering speed is maintained or enhanced without regard to additional computing overhead.
