* @param {number} [options.maximumAttenuation] Maximum attenuation in pixels. Defaults to the Cesium3DTileset's maximumScreenSpaceError.
|
|
* @param {number} [options.baseResolution] Average base resolution for the dataset in meters. Substitute for Geometric Error when not available.
|
|
* @param {boolean} [options.eyeDomeLighting=true] When true, use eye dome lighting when drawing with point attenuation.
|
|
