A companion sample codebase for a Zhihu article series on hand-building a next-generation game engine from scratch in C++. It implements a cross-platform engine with multiple graphics backends (OpenGL, Metal, DirectX 12, Vulkan), Bullet physics, and OpenGEX scene loading.

Use cases

• learn how a game engine works internally
• study graphics backend abstraction across OpenGL Metal Vulkan and DirectX 12
• follow a tutorial series building a game engine from scratch
• see how to integrate Bullet physics and OpenGEX scene graphs in C++
• example of cross-platform C++ engine builds with CMake including WebAssembly

When to choose

• you want educational, article-backed source code explaining engine architecture step by step
• you want to see multi-API rendering abstraction (OpenGL, Metal, DX12, Vulkan) in one codebase
• you prefer learning by reading and modifying a small engine rather than using a production engine

When to avoid

• you need a production-ready engine for shipping a game
• you need a permissive license - the license is non-standard/unspecified
• you need actively maintained platform support for Android, WebAssembly, or consoles
