Cesium3DTilesVoxelProvider

new Cesium.Cesium3DTilesVoxelProvider(options)
engine/Source/Scene/Cesium3DTilesVoxelProvider.js 45

A VoxelProvider that fetches voxel data from a 3D Tiles tileset.

Implements the VoxelProvider interface.

Name Type Description
options object Object with the following properties:
Name Type Description
url Resource | string | Promise.<Resource> | Promise.<string> The URL to a tileset JSON file.

Members

readonly componentTypes : Array.<MetadataComponentType>
engine/Source/Scene/VoxelProvider.js 171

Gets the metadata component types. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly dimensions : Cartesian3
engine/Source/Scene/VoxelProvider.js 111

Gets the number of voxels per dimension of a tile. This is the same for all tiles in the dataset. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly globalTransform : Matrix4|undefined
engine/Source/Scene/VoxelProvider.js 50

A transform from local space to global space. If undefined, the identity matrix will be used instead.
Inherited From:

readonly maxBounds : Cartesian3|undefined
engine/Source/Scene/VoxelProvider.js 99

Gets the maximum bounds. If undefined, the shape's default maximum bounds will be used instead. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly maximumTileCount : number|undefined
engine/Source/Scene/VoxelProvider.js 207

The maximum number of tiles that exist for this provider. This value is used as a hint to the voxel renderer to allocate an appropriate amount of GPU memory. If this value is not known it can be undefined. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly maximumValues : Array.<Array.<number>>|undefined
engine/Source/Scene/VoxelProvider.js 195

Gets the metadata maximum values. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly minBounds : Cartesian3|undefined
engine/Source/Scene/VoxelProvider.js 86

Gets the minimum bounds. If undefined, the shape's default minimum bounds will be used instead. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly minimumValues : Array.<Array.<number>>|undefined
engine/Source/Scene/VoxelProvider.js 183

Gets the metadata minimum values. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly names : Array.<string>
engine/Source/Scene/VoxelProvider.js 147

Gets the metadata names. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly paddingAfter : Cartesian3|undefined
engine/Source/Scene/VoxelProvider.js 135

Gets the number of padding voxels after the tile. This improves rendering quality when sampling the edge of a tile, but it increases memory usage. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly paddingBefore : Cartesian3|undefined
engine/Source/Scene/VoxelProvider.js 123

Gets the number of padding voxels before the tile. This improves rendering quality when sampling the edge of a tile, but it increases memory usage. This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly ready : boolean
engine/Source/Scene/VoxelProvider.js 28

Gets a value indicating whether or not the provider is ready for use.
Inherited From:

readonly readyPromise : Promise.<VoxelProvider>
engine/Source/Scene/VoxelProvider.js 39

Gets the promise that will be resolved when the provider is ready for use.
Inherited From:

readonly shape : VoxelShapeType
engine/Source/Scene/VoxelProvider.js 73

Gets the VoxelShapeType This should not be called before VoxelProvider#ready returns true.
Inherited From:

readonly shapeTransform : Matrix4|undefined
engine/Source/Scene/VoxelProvider.js 61

A transform from shape space to local space. If undefined, the identity matrix will be used instead.
Inherited From:

readonly types : Array.<MetadataType>
engine/Source/Scene/VoxelProvider.js 159

Gets the metadata types. This should not be called before VoxelProvider#ready returns true.

Methods

requestData(options) → Promise.<Array.<Array>>|undefined
engine/Source/Scene/VoxelProvider.js 253

Requests the data for a given tile. The data is a flattened 3D array ordered by X, then Y, then Z. This function should not be called before VoxelProvider#ready returns true.
Name Type Description
options object optional Object with the following properties:
Name Type Default Description
tileLevel number 0 optional The tile's level.
tileX number 0 optional The tile's X coordinate.
tileY number 0 optional The tile's Y coordinate.
tileZ number 0 optional The tile's Z coordinate.
Returns:
A promise to an array of typed arrays containing the requested voxel data or undefined if there was a problem loading the data.
Throws:
