OptionalanchorAbsolute altitude override (m, WGS84). Defaults to auto-grounding.
OptionalattenuationGeometric-error point attenuation (Cesium PointCloudShading): size points by their node's geometric error so coarse/far points draw bigger and the cloud stays dense at distance instead of going sparse. Default false. Toggle live with I3sPointCloudLayer.setAttenuation.
OptionalattributionOptionalauthRequest authorizer for all fetches (layer doc, node pages, geometry,
attributes, statistics). For a secured ArcGIS I3S service, pass an ESRI
authorizer (e.g. getEsriAuthorizer()), or configure one globally with
configureEsriAuth() and omit this. Public services need neither.
OptionalbudgetResident-memory budget (maxPoints / maxBytes).
OptionalclassPer-code LAS colour overrides applied over the ASPRS palette. Change live with
setClassColor; restore one code by passing undefined. Default: the stock palette.
OptionalclippingClipping planes (geographic; see ClippingPlanesOptions) applied to this layer's points (whole-point cull in the color, pick, and shadow-cast passes). Change at runtime via I3sPointCloudLayer.setClippingPlanes. Default none.
OptionalcolorInitial color mode. Default: 'rgb' when the service publishes an RGB attribute, else
'intensity'. RGB requires an RGB attribute.
OptionalcolorColour ramp for intensity and height modes. Change live with setColorRamp.
Default: the built-in Turbo ramp.
OptionaldatumVertical datum for auto-placement (I3S heights are orthometric, vcsWkid 5773):
'basemap' drops the ground on the map; 'ellipsoid'/'orthometric' place it at its
absolute height. Default: inherited from the service's declared vertical CRS (vcsWkid)
when a geoid is available, else 'basemap'. Switch live with
I3sPointCloudLayer.setDatum.
OptionaldebugOptionaldecoderDecoder: 'lepcc' (default, native Esri) | 'bvc' (pending) | a custom impl.
OptionaledlOptionaledlEDL darkening strength (default 80) + neighbour ring radius in px (default 1.4).
OptionalerrorDensity→geometricError scale (refine aggressiveness). Default 1.
OptionaleyeEye-dome lighting: a screen-space pass that shades depth gaps so a sparse cloud reads as a solid surface (Cesium/Potree EDL). Default false. Toggle live with I3sPointCloudLayer.setEyeDomeLighting.
OptionalfixedOptionalflyOptionalgeoidOptional — you should not normally need this.* The geoid undulation N (m) at the dataset, used to place absolutely-georeferenced data on mean-sea-level terrain. The SDK resolves it automatically (it fetches the EGM96 grid on demand and samples it at the dataset), so pass this only to override that — e.g. for a dataset referenced to a local vertical datum EGM96 does not model.
An override shifts placement by the DIFFERENCE between your value and the EGM96 undulation at the dataset — so passing the conventional EGM96 value for your area is a no-op rather than a ~30 m jump.
OptionalgeometricScale on the geometric error before projection (Cesium geometricErrorScale). Default 1.
OptionalgridRequantization grid (m) for the i32 position buffer. Default 0.001 (1 mm).
OptionalgroundMeasure + ground the dataset (default true).
OptionalhiddenLAS class ids to hide initially. Toggle live with I3sPointCloudLayer.setHiddenClasses / I3sPointCloudLayer.setClassVisible; discover which codes a scene contains with I3sPointCloudLayer.getClassifications.
OptionalintensityOptionalintensityOptionallodLOD distance-falloff exponent for the refine cusp. <1 keeps higher LOD further out
(more far detail, more data); 1 = standard SSE — the cusp matches Cesium/Esri at the same
maxScreenSpaceError (leanest far field). Default: the engine value (0.6). Pairs with
attenuation to load lean yet stay dense. Tune live with I3sPointCloudLayer.setLodFalloffPow.
OptionalmaximumAttenuation point-size ceiling, CSS px (Cesium maximumAttenuation). Default 16.
OptionalmaxOptionalmaxTarget on-screen point spacing (px). Lower = denser/more tiles. Default 1.5.
OptionalminOptionalonFired (with the current code/label/count list) when the set of LAS classification codes present in the streamed scene changes — wire it to (re)populate a class show/hide checklist without polling I3sPointCloudLayer.getClassifications.
OptionalonOptionalonOptionalonOptionalopacityOptionalpointOptionalreprojectProjected-CRS reprojection hook: (x,y,z) in the layer CRS → [lng°,lat°,h_m]. REQUIRED for non-geographic services; ignored for wkid 4326/4979.
OptionalrequestStatic auth/headers for all fetches — the escape hatch; superseded by auth.
OptionalroundOptionalshadowsCast + receive cascaded sun shadows (default false). When on, the cloud casts depth footprints into the shared ShadowCoordinator atlas (so it shadows meshes/terrain) and self-shadows by sampling it. Requires an active geo-sun (sun above the horizon). Toggle live with I3sPointCloudLayer.setShadows.
URL of the I3S SceneServer or its …/layers/{id}.
OptionalvisibleOptionalworkersDecode off the main thread in a Web Worker pool (default true).
Configuration for I3sPointCloudLayer. Only
idandurlare required; a public, geographic lidar service needs nothing else.The fields worth deciding up front: colorMode (left unset, the layer opens in
'rgb'when the service publishes an RGB attribute and'intensity'otherwise), datum (how the cloud is seated vertically), and maxScreenSpaceError with budget (how densely it streams and how much stays resident). A secured ArcGIS service needs auth; a projected service in a CRS the SDK's registry does not know needs reproject, or opening it throws.
