方法

返回值:

Throws:

• RuntimeException : Root must have content
• RuntimeException : Root tile content must have 3DTILES_content_voxels extension
• RuntimeException : Root tile must have implicit tiling
• RuntimeException : Tileset must have a metadata schema
• RuntimeException : Only box, region and 3DTILES_bounding_volume_cylinder are supported in Cesium3DTilesVoxelProvider

使用示例:

try {
  const voxelProvider = await Cesium3DTilesVoxelProvider.fromUrl(
    "http://localhost:8002/tilesets/voxel/tileset.json"
  );
  const voxelPrimitive = new VoxelPrimitive({
    provider: voxelProvider,
    customShader: customShader,
  });
  scene.primitives.add(voxelPrimitive);
} catch (error) {
  console.error(`Error creating voxel primitive: ${error}`);
}

定义的类型

属性:

属性名称	类型	可选	默认值	描述信息
className	string			The class in the tileset schema describing voxel metadata.
names	Array.<string>			The metadata names.
types	Array.<MetadataType>			The metadata types.
componentTypes	Array.<MetadataComponentType>			The metadata component types.
shape	VoxelShapeType			The VoxelShapeType.
dimensions	Cartesian3			The number of voxels per dimension of a tile. This is the same for all tiles in the dataset.
paddingBefore	Cartesian3	<可选>	Cartesian3.ZERO	The number of padding voxels before the tile. This improves rendering quality when sampling the edge of a tile, but it increases memory usage.
paddingAfter	Cartesian3	<可选>	Cartesian3.ZERO	The number of padding voxels after the tile. This improves rendering quality when sampling the edge of a tile, but it increases memory usage.
globalTransform	Matrix4	<可选>	Matrix4.IDENTITY	A transform from local space to global space.
shapeTransform	Matrix4	<可选>	Matrix4.IDENTITY	A transform from shape space to local space.
minBounds	Cartesian3	<可选>		The minimum bounds.
maxBounds	Cartesian3	<可选>		The maximum bounds.
minimumValues	Array.<Array.<number>>	<可选>		The metadata minimum values.
maximumValues	Array.<Array.<number>>	<可选>		The metadata maximum values.
maximumTileCount	number	<可选>		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.
