@ortho-earth/core

The rendering core of ortho-earth: vector tiles, terrain, rasters and labels drawn on a sphere (orthographic/perspective are one continuum — a slider, not a wall), with a WebGPU backend and a WebGL2 fallback.

This is the low-level layer. If you want a map you can put on a page, use @ortho-earth/globe — it hosts this core.

npm i @ortho-earth/core

What is inside

| Entry | What it gives | |---|---| | @ortho-earth/core | tile decode/build, draw lists, camera, flight, labels, GeoJSON overlays, buildings, gint layers | | ./gpu · ./gl | the two backends (WebGPU / WebGL2) | | ./camera · ./viewurl | cameraState/project/unproject, the #z/lat/lon hash grammar | | ./terrain · ./raster · ./raster-src | elevation atlases, XYZ/WMS/WMTS/PMTiles raster layers | | ./decode · ./tileformat · ./geodesic · ./geojson | MVT decode and the tile-format registry (MLT via @ortho-earth/tile-formats), Vincenty distance/area, GeoJSON → overlay | | ./worldstyle · ./worldpal | the map-face palettes (mono / dark / topo / sepia) | | ./workers/* | worker entries (tile, scene, gint, gint bake) |

The core knows no region. Country-specific knowledge (basemaps, elevation, buildings, search) is a declaration passed in from outside — see @ortho-earth/globe and its region packs.
