Physics simulation is an active research topic in games, because without realistic physics, even the most beautiful game feels static and lifeless. Although cloth simulation is not new in computer graphics, high level of details of cloth in video games is rare and mostly coarse due to complex and nonlinear physical properties of cloth, which requires substantial computing power necessary to simulate it in real-time. This paper presents a robust and scalable real-time cloth simulation framework by exploring a variety of modern simulation techniques to produce realistic cloth simulation for games. The framework integrates with OpenCL GPGPU library to leverage parallelism. The final result is an API for games development with enriched interactive environments.
