## What it is
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

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: game-engine, graphics, simulation
- domain: graphics, tutorials
- platform: windows, wasm, cpp
- tags: game-engine-from-scratch, tutorial-series, opengex, vulkan, directx12, metal, opengl, bullet-physics, ispc, educational-project, game-development, macos, linux, android
