Generation of crowded realistic scenes that include thousands of 3D objects for low altitude flights is not a widely covered topic. In this study we tried to generate immersive and dynamic realistic scenes for low altitude flights by using low cost PC configuration. At the end of the study encouraging results were obtained. Some features offered by high-end image generators regarding out-the-window scene were transported into our implementation. Hundreds of moving human beings, vehicles with realistic motion and very dense forests are rendered at interactive frame rates resulting in a low cost/high performance application. Limited number of pilots reviewed the scenes generated by our application and were satisfied.
