      Loading parameters.

      • Optionalcenter?: boolean

        Whether to center the points. Default is false.

      • OptionalcolorDepth?: string | number

        Option to oad every n points. Default is 1.

      • Optionaltransform?: FloatArrayParam

        Optional flattened 4x4 matrix to transform the points. Applied after centering, if specified.

    Returns Promise<void>

    Resolves when LAS has been loaded.

    Throws
