## What it is
Lamina is a TypeScript library providing an extensible, layer-based shader material system for ThreeJS, letting developers declaratively stack and blend visual effects on 3D materials. It integrates well with React Three Fiber and was inspired by Spline's layer material approach.

## Use cases
- create layered gradient materials for 3D objects in ThreeJS
- stack and blend shader effects declaratively in react-three-fiber
- build stylized 3D web scenes without writing raw GLSL
- compose depth, noise, and color layers on meshes
- prototype complex materials for WebGL visualizations

## When to avoid
- starting a new project — the repo is archived and unmaintained since April 2023
- you need reliable, performant custom shaders — the author recommends THREE-CustomShaderMaterial (CSM) instead
- production apps requiring ongoing support or bug fixes
- use cases needing a well-maintained shader abstraction layer
