## What it is
A collection of GLSL shaders for Unity that emulate the PlayStation 1 rendering style, including unlit, vertex lit, transparent, and reflective variants plus a posterize image effect. It reproduces retro features like affine texture mapping, fog, polygon cutout, and vertex distortion.

## Use cases
- make my unity game look like a ps1 game
- retro ps1 style shaders for unity
- emulate affine texture mapping in modern engine
- low poly retro aesthetic rendering
- ps1 style fog and vertex snapping effect

## When to choose
- you are building a Unity game with a PS1/retro low-poly aesthetic
- you want authentic affine texture warping and fog-based polygon cutout

## When to avoid
- you are not using Unity, since the shaders are Unity-specific
- you need modern PBR rendering or engines other than Unity

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, simulation
- domain: graphics
- platform: game-engine, cross-platform
- tags: shader, glsl, unity, retro, ps1, retro-shader, affine-texture-mapping, low-poly, game-development
