GaussianSplat3DTileContent

new Cesium.GaussianSplat3DTileContent()
engine/Source/Scene/GaussianSplat3DTileContent.js 21

Represents the contents of a glTF or glb using the KHR_gaussian_splatting and KHR_gaussian_splatting_compression_spz_2 extensions.

Implements the Cesium3DTileContent interface.

Members

readonly batchTableByteLength : number
engine/Source/Scene/GaussianSplat3DTileContent.js 225

Gets the amount of memory used by the batch table textures and any binary metadata properties not accounted for in geometryByteLength or texturesByteLength

readonly featuresLength : number
engine/Source/Scene/GaussianSplat3DTileContent.js 150

Gets the number of features in the tile. Currently this is always zero.

readonly geometryByteLength : number
engine/Source/Scene/GaussianSplat3DTileContent.js 190

The number of bytes used by the geometry attributes of this content.

readonly innerContents : Array
engine/Source/Scene/GaussianSplat3DTileContent.js 240

Gets the array of Cesium3DTileContent objects for contents that contain other contents, such as composite tiles. The inner contents may in turn have inner contents, such as a composite tile that contains a composite tile.
See:

readonly pointsLength : number
engine/Source/Scene/GaussianSplat3DTileContent.js 165

Equal to the number of Gaussian splats in the tile. Each splat is represented by a median point and a set of attributes, so we can treat this as the number of points in the tile.

readonly ready : boolean
engine/Source/Scene/GaussianSplat3DTileContent.js 254

Returns true when the tile's content is ready to render; otherwise false

readonly texturesByteLength : number
engine/Source/Scene/GaussianSplat3DTileContent.js 204

The number of bytes used by the textures of this content.

readonly tile : Cesium3DTile
engine/Source/Scene/GaussianSplat3DTileContent.js 292

The tile that this content belongs to.

readonly tileset : Cesium3DTileset
engine/Source/Scene/GaussianSplat3DTileContent.js 280

The tileset that this content belongs to.

readonly transformed : boolean
engine/Source/Scene/GaussianSplat3DTileContent.js 267

Returns true when the tile's content is transformed to world coordinates; otherwise false

readonly trianglesLength : number
engine/Source/Scene/GaussianSplat3DTileContent.js 178

Gets the number of triangles in the tile. Currently this is always zero because Gaussian splats are not represented as triangles in the tile content.

readonly url : Resource
engine/Source/Scene/GaussianSplat3DTileContent.js 304

The resource that this content was loaded from.

Methods

static Cesium.GaussianSplat3DTileContent.tilesetRequiresGaussianSplattingExt(tileset) → boolean
engine/Source/Scene/GaussianSplat3DTileContent.js 111

Performs checks to ensure that the provided tileset has the Gaussian Splatting extensions.
Name Type Description
tileset Cesium3DTileset The tileset to check for the extensions.
Returns:
Returns true if the necessary extensions are included in the tileset.

getFeature(batchId) → Cesium3DTileFeature
engine/Source/Scene/GaussianSplat3DTileContent.js 689

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:
See:

hasProperty(batchId, name) → boolean
engine/Source/Scene/GaussianSplat3DTileContent.js 670

Returns whether the feature has this property.
Name Type Description
batchId number The batchId for the feature.
name string The case-sensitive name of the property.
Returns:
true if the feature has this property; otherwise, false.
