Synthesizing Virtual Night Scene on OpenStreetMap

As modern game development technologies are emerging rapidly, virtual content synthesis for immersive gaming experiences became a popular research topic recently. Especially, as the game genres driven by modern life experiences within realistic virtual urban environments are gaining popularity, efficient and effective modeling approaches for synthesizing realistic urban environments are necessary. As a procedural modeling approach, synthesizing realistic urban scenes using OpenStreetMap (OSM) can result in satisfying results without demanding heavy manual efforts from game content designers. However, existing works that synthesize realistic virtual urban environments using OSM have not proposed the technical approach and experiment results that present realistic night scenes of virtual urban environments. Therefore, in this paper, we propose a novel procedural modeling approach to automatically synthesize realistic virtual night scenes on OpenStreetMap. The experiment results of synthesized urban night scenes validate the efficacy of our proposed technical approach.
