## What it is
Procedural GL JS is a JavaScript/WebGL library for embedding 3D map and terrain experiences in web pages, built on THREE.js. It is mobile-first, streaming raster map tiles and elevation data with a GPU-powered level-of-detail system.

## Use cases
- embed interactive 3D terrain maps in a website
- display outdoor landscapes with elevation data on mobile
- render 3D maps from MapTiler or other raster tile providers
- add markers and lines as overlays on a 3D map
- build a hike or route visualizer with 3D terrain

## When to choose
- you need smooth 3D terrain rendering optimized for mobile devices
- you want a simple API for 3D maps without dealing with 3D concepts directly
- you want a lightweight alternative to full 3D engines for map experiences

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, data-visualization, web-framework
- domain: web-development, frontend, graphics
- platform: browser
- tags: 3d-maps, webgl, threejs, terrain, mobile-first, mapping-engine, maps, javascript, web
