How to create any location 3D tile layers in Cesium map


I want to create my location 3D tile layers for cesium map. but how to create i have no idea because i am beginner in cesium. So anyone know how to create 3D tile layers for any specific location give your response.

I have this location 3D tile map

I want to create this location 3D tile data source. near San Francisco location

Solution

  • Here is San Francisco area 3d tile map with ArcGISTiledElevationTerrainProvider()

    Example code copied from Cesium demo link And replace url of Indexed 3D Scene (I3S) layer

    From

    https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/SanFrancisco_3DObjects_1_7/SceneServer/layers/0
    

    To

    https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/SanFrancisco_Bldgs/SceneServer?cacheKey=90e21aeb68997279
    

    I got from arcgis San Francisco 3D Buildings service in here

    And arcgis map (Scene Service Viewer)

    https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/SanFrancisco_Bldgs/SceneServer?view=sceneview&f=html&cacheKey=90e21aeb68997279

            // Center camera on I3S once it's loaded
            i3sProvider.readyPromise.then(function () {
                const center = Cesium.Rectangle.center(i3sProvider.extent);
                center.height = 10000.0;
                viewer.camera.setView({
                    destination: Cesium.Ellipsoid.WGS84.cartographicToCartesian(center),
                });

            // Add the i3s layer provider as a primitive data type
