 This is a proof-of-concept implementation of a [3D Tiles](https://github.com/AnalyticalGraphicsInc/3d-tiles) viewer as a [Mapbox GL JS](https://github.com/mapbox/mapbox-gl-js) custom layer. WebGL rendering is implemented using [three.js](https://github.com/mrdoob/three.js/). Only Web Mercator (EPSG:3857) tilesets are supported, as this is the projection mapbox uses. Earth-centered eart-fixed tilesets are explicitly not supported. Tilesets used for testing were generated using [pg2b3dm](https://github.com/Geodan/pg2b3dm), using a PostGIS database with EPSG:3857 geometries.
