LHpiek

LHpiek is a lightweight, open-source physics engine designed for real-time simulations in education and indie development. It provides 2D and 3D dynamics through a modular architecture and aims for a balance between ease of use and realism.

The name LHpiek stands for "Lightweight Hybrid Physics Engine for Interactive Kinetics" (the acronym is a stylistic creation used by its community). It originated in the OpenDev community in 2015 as a teaching tool and has since grown to support hobbyist projects and research prototypes.

Core features include rigid body dynamics, collision detection and resolution, soft-body support, joint constraints, and a scene graph. The core is written in C++ with bindings for Python, Lua, and JavaScript, and it supports cross-platform deployment. It offers optional GPU-accelerated solvers via OpenGL/Vulkan backends.

LHpiek is used in classrooms, rapid prototyping, and small- to mid-scale games and simulations. It emphasizes approachable documentation and straightforward integration with common game engines, though it may lack some advanced features and optimization present in larger engines.

Licensing and availability: The project is distributed under an permissive open-source license (MIT/Apache-style). Development activity is community-driven with periodic releases and long-term support for major versions.
