Quantized Mesh Source

A quantized-mesh source describes Cesium quantized-mesh terrain. Render it with a terrain layer. By default it is treated as geographic (EPSG:4326) with a TMS (south-origin) Y axis, matching Cesium’s convention.

Properties

Property	Type	Default	Description
type	"quantized-mesh"	(required)	Source type.
url	string	(required)	Tile URL template (contains {z}/{x}/{y}).
geographic	boolean	true	Use a geographic (EPSG:4326) tiling scheme; otherwise WebMercator.
tms	boolean	true	Whether the tile Y axis is south-origin (TMS).
requestVertexNormals	boolean	false	Request the oct-encoded per-vertex normals extension (octvertexnormals Accept header).
requestWaterMask	boolean	false	Request the watermask extension (watermask Accept header).
token	string	—	Bearer token sent as the Authorization header when fetching tiles.
minZoom	number	0	Minimum zoom level tiles are provided for.
maxZoom	number	20	Maximum zoom level new tiles are requested for.
overscaledMaxZoom	number	24	Maximum zoom overscaled tiles are used up to.

Example

import ThreeView from "@navaramap/three";

const terrain = view.addSource({
  type: "quantized-mesh",
  url: "https://example.com/terrain/{z}/{x}/{y}.terrain",
  requestVertexNormals: true,
});

view.addLayer({ type: "terrain", source: terrain });

// Style the terrain mesh with `terrain`.
view.addLayer({
  type: "terrain",
  source: terrain,
  terrain: { skirt: true, castShadow: true },
});
