Place markers on top of 3D Tiles model

Hi there,

I'm wondering if it's possible to place a marker / pin on top of a Cesium 3D tiles model?

Can someone please point me in the right direction?

Thanks for the help!

Check out the annotate ability in the 3D Tiles Sandcastle demo. Is that what you had in mind or something else?


That definitely looks close. How do I do this in the Sandcastle demo? I'm looking at it now and it's not obvious, also when I press "Style with info" it crashes.

This is a more self-contained example:

var viewer = new Cesium.Viewer(‘cesiumContainer’);

var scene = viewer.scene;

var canvas = viewer.canvas;

var handler = new Cesium.ScreenSpaceEventHandler(canvas);

var annotations = scene.primitives.add(new Cesium.LabelCollection());

var tileset = scene.primitives.add(new Cesium.Cesium3DTileset({

url : '../../../Specs/Data/Cesium3DTiles/Tilesets/Tileset/'


tileset.readyPromise.then(function(tileset) {

var boundingSphere = tileset.boundingSphere;, new Cesium.HeadingPitchRange(0, -2.0, 0));;


handler.setInputAction(function(movement) {

// Add annotation showing the height at the click location

var feature = scene.pick(movement.position);

if (Cesium.defined(feature) && scene.pickPositionSupported) {

    var cartesian = scene.pickPosition(movement.position);

    var cartographic = Cesium.Cartographic.fromCartesian(cartesian);

    var height = cartographic.height.toFixed(2) + ' m';


        position : cartesian,

        text : height,

        horizontalOrigin : Cesium.HorizontalOrigin.LEFT,

        verticalOrigin : Cesium.VerticalOrigin.BOTTOM,

        eyeOffset : new Cesium.Cartesian3(0.0, 0.0, -1.0)



}, Cesium.ScreenSpaceEventType.LEFT_CLICK);


We have some improvements coming to the 3D Tiles sandcastle which should fix that bug. Thanks for letting us now.
