## What it is
Oryol is a small, portable, extensible C++ 3D coding framework that renders through GL, GLES2, WebGL, Metal, and D3D11 from the same source. It runs on desktop, mobile, and web (emscripten) platforms and is built with the fips build system.

## Use cases
- build a small cross-platform 3d demo in c++
- compile a c++ graphics app to webgl with emscripten
- render the same scene with opengl, metal, and d3d11
- prototype 3d graphics experiments on raspberry pi
- create tiny webgl executables from c++

## When to choose
- you want a lightweight Orthodox C++ 3D framework for multi-platform demos
- you need WebGL/wasm output from C++ with very small binaries
- you want to study a well-documented minimal graphics framework design

## When to avoid
- you need an actively maintained framework with recent fixes
- you are starting a new production project - the author recommends Sokol headers instead
- you need a full-featured game engine with editor and tooling

## Facets
- artifact type: framework
- maturity: abandoned
- function: game-engine, graphics, animation
- domain: graphics, cross-platform
- platform: cross-platform, windows, wasm
- tags: cpp, 3d-graphics, opengl, metal, d3d11, webgl, emscripten, unmaintained, game-development, macos, linux, ios, android
