I use the ''GeoserverTerrainProvider.js''(which is to cesium b28) like this(which is reedit on cesium demo and the demo 'terrain' run successfully on my machine ) :
require(['Cesium','GeoserverTerrainProvider'], function(Cesium,GeoserverTerrainProvider) {
"use strict";
function createTerrainMenu(terrainProviders) {
var terrainProviderOptions = terrainProviders.map(function(terrainProvider) {
return {
text : terrainProvider.name
};
});
Sandcastle.addToolbarMenu(terrainProviderOptions, function() {
scene.terrainProvider = terrainProviders[this.selectedIndex].provider;
}, 'terrainMenu');

});

But it can't run,press F12 and find some infomation like this :

always error tips "Cesium is not defined GeoserverTerrainProvider.js:536 "
Can someone help me!

[kaktus40]

Hello,the plugin GeoserverTerrainProvider was written to work with builded Cesium (Cesium.js) which means that GeoserverTerrainProvider use functions with namespace "Cesium" like in line 536 (Cesium.Ellipsoid.WGS84). To use GeoserverTerrainProvider in sandCastle, you should adapt the plugin (write a require command which defines all imorts; remove all namespace Cesium...)
Good luck

thanks for your guidance,I solve it.
