ABSTRACT
Computer games provide a virtual environment, which is usually expected to simulate the real world. Physics-based simulation in games (or simply game physics) serves the purpose by adopting the physics models, which include the physics entities such as mass, velocity, acceleration, force, etc. In games, physics-based simulation is becoming an indispensable component, and many physics engines are available, ranging from high-price commercial engines to open-source engines. Game physics includes a wide spectrum of topics, and we can find many books devoted to it [37, 38].
