Cesium3DTileContent

Members

readonlybatchTableByteLength : Number

Gets the amount of memory used by the batch table textures, in bytes.

readonlyfeaturesLength : Number

Gets the number of features in the tile.

readonlygeometryByteLength : Number

Gets the tile's geometry memory in bytes.

readonlyinnerContents : Array

Gets the array of Cesium3DTileContent objects that represent the content a composite's inner tiles, which can also be composites.

See:

• https://github.com/AnalyticalGraphicsInc/3d-tiles/blob/master/TileFormats/Composite/README.md

readonlypointsLength : Number

Gets the number of points in the tile.

Only applicable for tiles with Point Cloud content. This is different than Cesium3DTileContent#featuresLength which equals the number of groups of points as distinguished by the BATCH_ID feature table semantic.

See:

• https://github.com/AnalyticalGraphicsInc/3d-tiles/blob/master/TileFormats/PointCloud/README.md#batched-points

readonlyreadyPromise : Promise.<Cesium3DTileContent>

Gets the promise that will be resolved when the tile's content is ready to render.

readonlytexturesByteLength : Number

Gets the tile's texture memory in bytes.

readonlytrianglesLength : Number

Gets the number of triangles in the tile.

readonlyurl : String

Gets the url of the tile's content.

Methods

getFeature(batchId) → Cesium3DTileFeature

Returns the Cesium3DTileFeature object for the feature with the given batchId. This object is used to get and modify the feature's properties.

Features in a tile are ordered by batchId, an index used to retrieve their metadata from the batch table.

Name	Type	Description
batchId	Number	The batchId for the feature.

Returns:

The corresponding Cesium3DTileFeature object.

Throws:

• DeveloperError : batchId must be between zero and Cesium3DTileContent#featuresLength - 1.

See:

• https://github.com/AnalyticalGraphicsInc/3d-tiles/tree/master/TileFormats/BatchTable.

hasProperty(batchId, name) → Boolean

Determines if the tile's batch table has a property. If it does, each feature in the tile will have the property.

Name	Type	Description
batchId	Number	The batchId for the feature.
name	String	The case-sensitive name of the property.

Returns:

true if the property exists; otherwise, false.
