This example shows a simple interactive map of New York City, with buildings, roads, water, and landuse rendered in 3D perspective using Tangram’s WebGL engine. The map uses Leaflet for panning and zooming, and Tangram’s leafletLayer to load a TopoJSON scene from Mapzen vector tiles. A scene file defines camera, lighting, and draw rules, including extruded building polygons that appear when zoomed in past level 15.
