Matter-js is a 2D rigid body physics engine written in JavaScript for simulating realistic physical interactions, collisions, and dynamics in web browsers. It functions as a web physics simulation library that calculates motion, gravity, and constraints for objects rendered on a web canvas. The library includes a built-in canvas physics visualizer to draw physical bodies, joints, and constraints for debugging and gameplay. It distinguishes itself through a plugin system that supports recursive dependency resolution and internal method patching to inject custom logic into the engine's executio

Rapier 是一个跨平台的物理引擎和刚体动力学求解器，专为 2D 和 3D 模拟而设计。它作为一个碰撞检测系统和机器人模拟框架，为计算不同环境下的物理交互提供了统一的 API。 该引擎凭借专业的机器人功能脱颖而出，包括用于导入 URDF 和 STL 模型以控制多体链的工具包。它通过逆运动学计算支持精确的机械运动，并应用 PID 控制器进行动态物体控制。 模拟范围涵盖了广泛的物理功能，包括用于地形遍历的运动学角色控制器和用于车辆动力学的射线投射模型。它具有带连续碰撞检测的多阶段碰撞流水线以防止物体穿透，以及用于使用旋转、棱柱和球形关节进行关节运动约束的系统。 该框架包含用于通过 STL、URDF 和 XML 格式导入外部几何定义的实用程序，并提供了一个后端无关的调试界面，用于可视化内部物理状态和 3D 场景。

Space Station 14 is a C# multiplayer game and roleplay simulation framework. It is built upon an Entity-Component-System (ECS) game engine that separates logic into systems and data into components to manage complex entity interactions. The project functions as a grid-based physics simulator with a YAML data-driven prototype system for defining game objects. The project features a specialized 2D sprite rendering engine that maps server-side appearance data to client-side shaders. It implements a networking model with client-side prediction and dirty-flagged state synchronization to reduce inp

mujoco_menagerie is a curated library of physical robot specifications and XML model definitions designed for standardized dynamics and contact simulation. It provides a collection of high-quality robot model files for humanoids, quadrupeds, and manipulators, alongside detailed kinematic and inertial parameters used to reproduce real-world robot behavior in virtual environments. The project serves as a repository of robotics simulation assets and MJCF model definitions optimized for accuracy. It includes standardized model libraries specifically for bipedal, quadrupedal, and humanoid hardware
