  Returns SceneNode | null

factoryDeps

• factoryDeps(): LoaderFactoryDeps

  Per-call dependency snapshot for the loader factory (incl. sliceCache).

  Returns LoaderFactoryDeps

  • [key: string]: unknown

    Any additional attributes

  • Optionaltransform?: readonly number[]

    Transformation matrix (16 elements for a column-major 4x4 matrix). Typed as readonly number[] because zarr metadata is parsed dynamically; see import('../types/zarr').Matrix4x4 for the narrowed 16-tuple shape.

  • Optionalnd_transform?: NdTransformMap

    Per-dimension transforms for non-displayed dimensions

  • Optionalopacity?: number

    Rendering attributes

  • Optionalabsorption?: number

  • Optionalgamma?: number

  • Optionalintensity?: number

  • Optionaloffset?: number

  • Optionalblending_mode?: string

  • Optionaljoin?: string

    Lines-only join style at degree-2 polyline joints: 'none' | 'miter' (#790).

  • Optionalmax_radius?: number

  • Optionaln_points?: number

  • Optionallayer?: boolean

    Whether this node is exposed as a layer in the Layers panel

  • Optionalvisible?: boolean

    Initial visibility when the scene loads (default: true). Authoring-time only.

  • Optionalcolor_data_range?: [number, number]

    Min/max of color data, computed at encoding time

  • Optionalamplitude_data_range?: [number, number]

    Min/max of amplitude data (GSplats), computed at encoding time

  • Optionalscalar_data_range?: [number, number]

    Min/max of scalar data (Points/Lines), computed at encoding time

  • Optionalcolormap?: string

    Colormap name for scalar-to-color mapping (e.g., "viridis", "green", "custom")

  • Optionalhas_scalars?: boolean

    Whether this node has scalar values for colormap lookup

  • Optionalextend_to_all?: string[]

    Dimensions to extend visibility across (points visible at all values)

resolveObject

• resolveObject(path: string): Object3D<Object3DEventMap> | null | undefined

  Resolve the live rendered object for a loader path.

  Parameters

  • path: string

  Returns Object3D<Object3DEventMap> | null | undefined
