The code at the bottom of the example Kevin pointed you to is responsible for adding the terrain. Add the code in whatever file you’re creating the cesium viewer in.
var scene = viewer.scene;
var centralBody = scene.getPrimitives().getCentralBody();
centralBody.depthTestAgainstTerrain = true;
var terrainProvider = … /* whatever terrain provider you want to use*/
centralBody.terrainProvider = terrainProvider;
