## What it is
LYGIA is a granular, multi-language shader library of reusable functions supporting GLSL, HLSL, Metal, WGSL, WESL, and CUDA. It is designed for performance and flexibility, with integrations for major engines and frameworks like Unity, Unreal, Three.js, and openFrameworks.

## Use cases
- reuse shader functions across glsl and hlsl projects
- add procedural drawing functions to webgl shaders
- port shaders between opengl, vulkan, and webgpu
- resolve shader #include dependencies online
- prototype fragment shaders for creative coding
- use a common shader library across unity and unreal

## When to choose
- you need battle-tested, granular shader functions in multiple shading languages
- you want to ship shaders across many engines and platforms from one codebase
- you want to include shader files via #include or an online resolver

## When to avoid
- you need a full shader engine or material system rather than reusable functions
- your environment cannot resolve #include directives and you cannot bundle files
- you need a permissively licensed library with a standard OSI license

## Facets
- artifact type: library
- maturity: active
- function: graphics, image-processing, math, sdk
- domain: graphics, web-development, cross-platform
- platform: cross-platform, cpp, rust, python
- tags: shader-library, glsl, hlsl, wgsl, metal, cuda, webgpu, opengl, vulkan, directx, creative-coding, game-development, gpu, web
