I'm using ol3-cesium for creating 3D globe and cesium terrain provider to show terrain data on globe its working fine.

this.scene.terrainProvider = new Cesium.CesiumTerrainProvider({

url : "http://" + window.location.host + "/tilesets/world",

requestVertexNormals : true

});

But on click of a button i want to hide the terrain data or remove terrain provider from scene object, which ever is possible.

use the following function to toggle the terain

function toggleTerrain(){    
    var scene = ol3d.getCesiumScene();
    var terrainProvider;
    if (scene.terrainProvider._url){
        //add a simple terain so no terrain shall be preseneted
        terrainProvider = new Cesium.EllipsoidTerrainProvider({});
    }
    else {
        //enable the terain
        terrainProvider = new Cesium.CesiumTerrainProvider({
            url : '//cesiumjs.org/stk-terrain/tilesets/world/tiles',
            requestWaterMask: true
        });
    }
    scene.terrainProvider = terrainProvider;
}

your key snippet is

terrainProvider = new Cesium.EllipsoidTerrainProvider({});
scene.terrainProvider = terrainProvider;
  • Is there any way to load terrain data of two places at same time?? – vinni May 5 '16 at 8:16
  • I am not sure but it doesnt sound logic. what if first terrain sais is 100m and second 50 meters. What would be the visual effect in that case? – pavlos May 5 '16 at 8:19
  • when i'm using above code snippet sometimes its loading my globe again and again in loop. – vinni May 5 '16 at 8:44
  • can you make a fiddle to demonstrate? – pavlos May 5 '16 at 8:50
