OSM Buildings is a JavaScript library for showing building geometry on interactive maps.
Example: https://osmbuildings.org/
The standalone WebGL version odf OSM Buildings is located here: https://github.com/OSMBuildings/OSMBuildings
There is also documentation of OSM Buildings Server side: https://github.com/kekscom/osmbuildings/blob/master/docs/server.md
Example https://osmbuildings.org/
It's safe use the master branch for production.

{ attribution: 'Map tiles © <a href="https://mapbox.com">Mapbox</a>', maxZoom: 17 }).addTo(map);Add the buildings layer.
new OSMBuildings(map).load();As a popular alternative, you could pass a GeoJSON FeatureCollection object.
Geometry types Polygon, Multipolygon and GeometryCollection are supported.
Make sure the building coordinates are projected in EPSG:4326.
Height units m, ft, yd, mi are accepted, no given unit defaults to meters.

new OSMBuildings(map).load();| Constructor | Description |
|---|---|
| new OSMBuildings(map) | Initializes the buildings layer for a given map engine. Currently Leaflet and OpenLayers are supported. |
Constants
| Option | Type | Description |
|---|---|---|
| ATTRIBUTION | String | Holds OSM Buildings copyright information. |
| VERSION | String | Holds current version information. |
Methods
| Method | Description |
|---|---|
| style({Object}) | Set default styles. See below for details. |
| date(new Date(2017, 15, 1, 10, 30))) | Set date/time for shadow projection. |
| each({Function}) | A callback wrapper to override each feature's properties on read. Return false in order to skip a particular feature. Callback receives a feature object as argument. |
| click({Function}) | A callback wrapper to handle click events on features. Callback receives an object { featureId{number,string}, lat{float}, lon{float} } as argument. |
| set({GeoJSON FeatureCollection}) | Just add GeoJSON data to your map. |
| load({Provider}) | Without parameter, it loads OpenStreetMap data tiles via an OSM Buildings proxy. This proxy enables transparent data filtering and caching. Interface of such provider is to be published. |
