I3S works but is SLPK file supported?


CesiumJS supports I3S nowadays to but can it also support .slpk files somehow? Or does it always need ArcGis server in order to load content from .slpk packages?


I3S is supported via web APIs like ArcGIS services or servers. This is a pretty common paradigm with streaming formats. For instance, we support 3D Tiles but not loading .3dtile files directly. And we support terrain, but do not load .terraindb files directly.

But if you have more info on use cases for loading .slpk files directly, I would suggest opening a feature request on CesiumJSā€™s GitHub with more details.
