3D Tiles Source

A 3d-tiles source points at a 3D Tiles tileset (a tileset.json hierarchy). Render it with a 3d-tiles layer.

Properties

Property	Type	Default	Description
`type`	`"3d-tiles"`	(required)	Source type.
`url`	`string`	(required)	URL of the `tileset.json`.
`crs`	`string`	—	Coordinate reference system of the content.

Supported Specifications

3D Tiles 1.0

Tile Format	Description
b3dm (Batched 3D Model)	Batched 3D models such as buildings.
pnts (Point Cloud)	Point cloud data. See PNTS attributes.
Google Photorealistic 3D Tiles	Photorealistic tiles provided by Google Maps Platform.

PNTS attributes

Navara reads only part of the pnts feature table. Point colors are interpreted as sRGB. A tile that stores its positions only as POSITION_QUANTIZED is not rendered.

Semantic	Support
`POSITION`	✅
`POSITION_QUANTIZED`	❌
`RTC_CENTER`	✅
`RGB`	⚠️ Draco-compressed tiles only
`RGBA`	⚠️ Draco-compressed tiles only
`RGB565`	❌
`CONSTANT_RGBA`	❌
`NORMAL` / `NORMAL_OCT16P`	❌
`BATCH_ID` and the batch table	❌
`3DTILES_draco_point_compression`	⚠️ `POSITION`, `RGB`, and `RGBA` only

3D Tiles 1.1

Feature	Description
GLB content	Tiles using GLB (binary glTF) as the content format.
GLB POINTS primitive	Point cloud rendering for glTF meshes with `mode: POINTS` (3D Tiles 1.1 point cloud).
`EXT_mesh_features`	Feature identification via FeatureId sets in glTF meshes.
`EXT_structural_metadata`	Access to per-feature metadata via property tables embedded in glTF assets.
`KHR_draco_mesh_compression`	Decoding of Draco-compressed mesh data.
`KHR_mesh_quantization`	Quantized vertex attributes for compact glTF assets.
`EXT_meshopt_compression`	Decoding of meshopt-compressed buffers.

Example

import ThreeView from "@navaramap/three";

const tileset = view.addSource({
  type: "3d-tiles",
  url: "https://example.com/tileset.json",
});
view.addLayer({ type: "3d-tiles", source: tileset, model: { opacity: 1.0 } });
