help me to use cesium terrain server

[dizzyto]

Hello.

I’m using Cesium js. and i’m planning to use cesium-terrain-server.
Because I have fine DEM of South Korea.

so I installed Go language, and pull git in my server.
I can reach this data in website.
Here is Log

and website capture.

Terrain data was made by ctb-tiles(Cesium Terrain Builder).
But in Cesiumjs, i failed to load data.

var terrainProvider = new Cesium.CesiumTerrainProvider({
url: 'http://URL:PORT/customTileset/',
});

viewer.scene.terrainProvider = terrainProvider;
It doesn’t even import the layer.json file.
I checked Chrome dev mode in network tab.

I can reach with browser. it means server and ports are fine.
I can even check the file with the browser.

But i failed to get data in cesium js.
How can i fix it?

Please help.

Regards.

Hey there!
const viewer = new Viewer('cesiumContainer', {
terrainProvider: await CesiumTerrainProvider.fromUrl(
'http://localhost:8003/terrain',
),
});
I have built tiles using Cesium Tile Builder and using them on CesiumJS like this. I can get the tileset but this is the error I get:
"An error occurred in "CesiumTerrainProvider": Failed to obtain terrain tile X: 0 Y: 0 Level: 0. Error message: "RangeError: Invalid typed array length: 8894653434""
Because of that I was trying to use Cesium Tile Server but Docker container for that has some issues. :(
Would be happy if you write a response here in case you find a solution.
Thanks!

Hi Natalia I hope you already found a solution to your problem. I have a working example, and I followed tumgis-ctb docker document ( https://hub.docker.com/r/tumgis/ctb-quantized-mesh) and it all worked. Please try it and let me know. Kobi
