LOD control when uploading to Cesium Ion

Hello. When uploading data to Cesium Ion, is there any way to modify the tiling parameters. For example, the LOD thresholds? We want to ensure models of different sizes display correctly alongside each other. Thanks in advance!

Hi,

While you can’t specify LOD thresholds while tiling, our tilers default to creating tilesets with the highest LOD possible. If you are seeing an issue where you think this may not be the case please let us know.

However, it is possible to tweak the amount of tiles being loaded on the client. Which client are you using to load your data?

Thanks,
Ankit

Hi Ankit,

Many thanks for clarifying the first point. We are using CesiumJS - we are only interested in a limited area of the globe, is it possible to only load the terrain and imagery we need?

Thanks in advance

Hi,

Do you have terrain and imagery assets that you are trying to display and turn off all other imagery/terrain? Or are you trying to view only a subsection of larger datasets like Cesium World Terrain?

Thanks,
Ankit

Hi Ankit, we are using Cesium Ion’s built-in imagery and terrain. Does Cesium only load what is necessary or should we be declaring somewhere in the code which region of the globe to render for efficiency? Thanks!

Hi,

Yes the default behavior is for Cesium to only load the necessary tiles based on where your viewer is, you shouldn’t need to declare in your code for this kind of efficiency. CesiumJs loads tiles based on the position of your viewer and level of detail so as you start zooming in/moving to a location inside the viewer, it will start loading more detailed tiles only for that location.

Thanks,
Ankit

Great, thanks Ankit.
