Cesium3DTile

new Cesium.Cesium3DTile(tileset, baseResource, header, parent)

A tile in a Cesium3DTileset. When a tile is first created, its content is not loaded; the content is loaded on-demand when needed based on the view.

Do not construct this directly, instead access tiles through Cesium3DTileset#tileVisible.

参数名称 类型 描述信息
tileset Cesium3DTileset The tileset
baseResource Resource The base resource for the tileset
header object The JSON header for the tile
parent Cesium3DTile The parent tile of the new tile
