This article briefly describes some technologies applied to current real-time simulation training systems. It focuses on nowadays and future trends both in hardware and software architectures. The most important open source and commercially available physics engines are briefly described along with some scene graph management libraries. Additionally, cluster-based simulator issues are also discussed, including the main problems that arise from using distributed GPU programming. An analysis of current state of the art regarding web browser-based simulators is also done. Finally new trends and cutting-edge research that is done in the real-time simulation field are discussed.
