## What it is
SEGI is a fully-dynamic voxel-based global illumination system for the Unity game engine, distributed as a Unity package of C# scripts and shaders. It provides real-time, dynamic GI lighting without baked lightmaps.

## Use cases
- add real-time global illumination to a Unity scene
- light dynamically changing environments without baking lightmaps
- achieve voxel-based GI in Unity games
- improve indoor and outdoor lighting realism in Unity
- replace baked lighting with fully dynamic indirect lighting

## When to choose
- you need fully dynamic global illumination in Unity
- your scenes change at runtime so baked lightmaps are not viable
- you want an MIT-licensed GI solution you can modify

## When to avoid
- you need a maintained solution - the last release was in 2018
- you target low-end mobile hardware where voxel GI is too expensive
- you use a Unity render pipeline incompatible with SEGI's shaders

## Facets
- artifact type: plugin
- maturity: abandoned
- function: graphics, simulation, game-engine
- domain: graphics, simulation
- platform: game-engine, cross-platform
- tags: unity, global-illumination, voxel-gi, shaders, rendering, real-time-lighting, game-development
