Properties

Property	Type	Description
basisTranscoderPath?	string	(Optional) A path to that contains the basis universal library. e.g: https://unpkg.com/three@0.129.0/examples/js/libs/basis - Default: undefined
cesiumIONToken?	string	(Optional) A Cesium ION access token when loading tilesets from Cesium ION.
computeNormals?	boolean	(Optional) When viewing b3dm (mesh) tiles, compute the vertex normals - Default: false.
debug?	boolean	(Optional) Debug mode: Show tile bounding boxes. Make sure to add the boxes to the scene from Runtime.getTileBoxes() - Default: false
dracoDecoderPath?	string	(Optional) A path to that contains the draco library. e.g: https://unpkg.com/three@0.129.0/examples/js/libs/draco - Default: undefined
geoTransform?	GeoTransform	(Optional) How to handle geo transformations: Reset any geo location and place the model at (0,0,0), Apply Mercator projection (for use with ccommon 2D mapping applications, or convert WGS84 long/lat to 3D cartesian coordinates)- Default: Reset
material?	Material	(Optional) Apply a custom material, supports both b3dm (mesh) tiles and Point Cloud tiles - Default: undefined *
maxConcurrency?	number	(Optional) Maximum worker thread concurrency when processing DRACO-compressed tiles - Default: 1 worker.
maximumMemoryUsage?	number	(Optional) Maximum GPU memory (MB) to use for displaying tiles. May go over the limit if tiles within the camera viewport exceed that ammount - Default: 32.
maximumScreenSpaceError?	number	(Optional) determines the distance from tiles in which they are refined, depending on their geometrical size. increase the value to load lower lod tiles from the same view distance (increases performnace) - default: 16.
maxRequests?	number	(Optional) When thorttling requests, how many requests can launch simultaneously - Default: 64
pointCloudColoring?	PointCloudColoring	(Optional) When viewing Point Cloud tiles, how should the points be colored (PointCloudColoring) - Default: PointCloudColoring.White
pointSize?	number	(Optional) Point size for Point Cloud tiles - Default: 1.0
preloadTilesCount?	number	(Optional) When using a three.js loading manager, do not call onLoad until this number of tiles were loaded - Default: undefined
shaderCallback?	(shader: Shader, renderer: WebGLRenderer) => void	(Optional) When viewing b3dm (mesh) tiles, a callback to update shader uniforms - Default: undefined
shading?	Shading	(Optional) When viewing b3dm (mesh) tiles, which type of Shading is used - Default: Shading.FlatTexture
skipLevelOfDetail?	boolean	(Optional) _EXPERIMENTAL_: Skip traversal mechanism, not yet supported. Default: false
throttleRequests?	boolean	(Optional) Whether to throttle network requests so that tiles got out of the frame before the request launched, would not be requested - Default: true
transparent?	boolean	(Optional) Whether to set the material as transparent - Default: false
updateInterval?	number	(Optional) Interval in seconds for the traverser to check in an update is needed - Default: 0.1.
updateTransforms?	boolean	(Optional) Whether to check if the tileset was transformed, set to true if the model is changes position in runtime. Default: true
viewDistanceScale?	number	(Optional) 0-1 scale for the LOD quality. A lower value loads tiles from lower LODs (increases performance).
wireframe?	boolean	(Optional) When viewing b3dm (mesh) tiles, show meshes as wireframe - Default: false.
worker?	boolean	(Optional) Whether to use workers when processing DRACO-compressed tiles - Default: true.
