Provides voxel data. Intended to be used with
VoxelPrimitive.
This type describes an interface and is not intended to be instantiated directly.
Experimental
This feature is not final and is subject to change without Cesium's standard deprecation policy.

成员(属性)
readonly componentTypes : Array.<MetadataComponentType>
Gets the metadata component types.
This should not be called before
VoxelProvider#ready returns true.
readonly dimensions : Cartesian3
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.
readonly globalTransform : Matrix4|undefined
A transform from local space to global space. If undefined, the identity matrix will be used instead.
readonly maxBounds : Cartesian3|undefined
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.
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.
Gets the metadata maximum values.
This should not be called before
VoxelProvider#ready returns true.
readonly minBounds : Cartesian3|undefined
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.
Gets the metadata minimum values.
This should not be called before
VoxelProvider#ready returns true.
Gets the metadata names.
This should not be called before
VoxelProvider#ready returns true.
readonly paddingAfter : Cartesian3|undefined
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.
readonly paddingBefore : Cartesian3|undefined
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.
readonly shape : VoxelShapeType
Gets the
VoxelShapeType
This should not be called before VoxelProvider#ready returns true.
readonly shapeTransform : Matrix4|undefined
A transform from shape space to local space. If undefined, the identity matrix will be used instead.
readonly types : Array.<MetadataType>
Gets the metadata types.
This should not be called before
VoxelProvider#ready returns true.
方法
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.
