## What it is
Lumix Engine is an open-source 3D game engine written in C++ with a built-in editor and entity-component-system architecture. It uses data-oriented design and ships with showcase sample projects and MIT licensing.

## Use cases
- build a 3D game with an open-source engine
- create a platformer or tower defense game
- prototype 3D scenes in a visual editor
- learn how a C++ game engine works internally
- develop games on Windows or Linux

## When to choose
- you want a lightweight, fully open-source C++ 3D engine with an editor
- you prefer data-oriented design and ECS architecture
- you need MIT licensing for commercial or hobby projects

## When to avoid
- you need a large ecosystem, asset store, and extensive tutorials
- you require console or mobile platform support out of the box
- you prefer engines with visual scripting or blueprint systems

## Facets
- artifact type: framework
- maturity: active
- function: game-engine, gui, graphics, simulation
- domain: graphics, cross-platform
- platform: windows, cpp
- tags: 3d, entity-component-system, data-oriented-design, editor, open-source-engine, game-development, linux
