CesiumJS
1

I need to render 3d objects into osm imagery view. But in my country i dont have access to ion assets (assets.ion.cesium.com) without vpn. So i s there way to use cesium in general in this case with other providers?

This will create a void globe that does not use Cesium Ion.
```

const viewer = new Cesium.Viewer("cesiumContainer", {
    imageryProvider: false,
    baseLayerPicker: false
});

Then add your custom provider.

You could also use the Terrain from offline mode
