VoxelProvider
查阅Mars3D API

Provides voxel data. Intended to be used with VoxelPrimitive. This type describes an interface and is not intended to be instantiated directly.

new Cesium.VoxelProvider()
engine/Source/Scene/VoxelProvider.js 23

Experimental

This feature is not final and is subject to change without Cesium's standard deprecation policy.

成员(属性)

constant availableLevels : number|undefined
engine/Source/Scene/VoxelProvider.js 184

The number of levels of detail containing available tiles in the tileset.

constant componentTypes : Array.<MetadataComponentType>
engine/Source/Scene/VoxelProvider.js 146

Gets the metadata component types.

constant dimensions : Cartesian3
engine/Source/Scene/VoxelProvider.js 99

Gets the number of voxels per dimension of a tile. This is the same for all tiles in the dataset.

constant globalTransform : Matrix4
engine/Source/Scene/VoxelProvider.js 51

A transform from local space to global space.
默认值: Matrix4.IDENTITY

constant maxBounds : Cartesian3|undefined
engine/Source/Scene/VoxelProvider.js 90

Gets the maximum bounds. If undefined, the shape's default maximum bounds will be used instead.

constant maximumTileCount : number|undefined
engine/Source/Scene/VoxelProvider.js 175

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.

constant maximumValues : Array.<Array.<number>>|undefined
engine/Source/Scene/VoxelProvider.js 164

Gets the metadata maximum values.

constant minBounds : Cartesian3|undefined
engine/Source/Scene/VoxelProvider.js 80

Gets the minimum bounds. If undefined, the shape's default minimum bounds will be used instead.

constant minimumValues : Array.<Array.<number>>|undefined
engine/Source/Scene/VoxelProvider.js 155

Gets the metadata minimum values.

constant names : Array.<string>
engine/Source/Scene/VoxelProvider.js 128

Gets the metadata names.

constant paddingAfter : Cartesian3
engine/Source/Scene/VoxelProvider.js 119

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.
默认值: Cartesian3.ZERO

constant paddingBefore : Cartesian3
engine/Source/Scene/VoxelProvider.js 109

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.
默认值: Cartesian3.ZERO

constant shape : VoxelShapeType
engine/Source/Scene/VoxelProvider.js 70

Gets the VoxelShapeType

constant shapeTransform : Matrix4
engine/Source/Scene/VoxelProvider.js 61

A transform from shape space to local space.
默认值: Matrix4.IDENTITY

constant types : Array.<MetadataType>
engine/Source/Scene/VoxelProvider.js 137

Gets the metadata types.

方法

requestData(options) → Promise.<VoxelContent>|undefined
engine/Source/Scene/VoxelProvider.js 39

Requests the data for a given tile.
参数名称 类型 描述信息
options object 可选 Object with the following properties:
参数名称 类型 默认值 描述信息
tileLevel number 0 可选 The tile's level.
tileX number 0 可选 The tile's X coordinate.
tileY number 0 可选 The tile's Y coordinate.
tileZ number 0 可选 The tile's Z coordinate.
返回值:
A promise resolving to a VoxelContent containing the data for the tile, or undefined if the request could not be scheduled this frame.
