Numerical Calculation and Optimization Algorithm Based on Unity Physics Engine

In this paper, the physics engine of Unity is used to simulate the construction of physical models in the real world. Based on numerical calculation and optimization algorithms, the fast multipole algorithmm and hierarchical collision detection algorithm are used to improve the calculation methods and algorithms. In combination with the API of related physics engines, the real physical system is quickly realized, thus improving the development efficiency. Optimize the operation logic of model data to make the operation effect more stable and smooth.
