Hi Richard, sorry, but this is currently not possible out of the box with the JavaScript API. It is planed, but not for this year. You would need to do some sort of workaround. In  some web scenes of geological surfaces, they convert the data to a scene service. For example in this scene: Scene Viewer. Is this what you are after? I've never done it myself, but I've asked around and the following workflow would lead you to something like that: - Use Raster to TIN to covert your DEM to a polygon based representation: http://pro.arcgis.com/en/pro-app/tool-reference/3d-analyst/raster-to-tin.htm - Use Interpolate Polygon to Multipatch: http://pro.arcgis.com/en/pro-app/tool-reference/3d-analyst/interpolate-polygon-to-multipatch.htm - for large areas, you can experiment with having a grid of polygons (rather than one big one) to create multiple multipatch features per surface for improved performance. ...

Hi James, could you post a snippet with your code? That way it's easier to debug... But on a first glance looks like you're passing a symbol layer directly to the constructor of the symbol. You should pass it to the symbolLayers property, like this:  symbol: new MeshSymbol3D({    symbolLayers: [       new FillSymbol3DLayer({         material: {            color: "#ffffff"         }      })    ] })‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

As previously mentioned, we are working on exposing more functionality in a future release, but for now we only exposed the widget and the viewmodel, which allow you to plug the widget in your app and use as is. The most that users can do at the moment is to have their own UI for it and listen for changes in the state. Currently with public API you can't programmatically activate the widget, nor deactivate it. You also cannot change the style. My question is again: can you tell us your use case? We will definitely expose the activation mechanism once we decide on the public API. But changing the style is currently not in our radar. Unless we have feedback on how this might be used. ...

nice, in 4.8 you'll have it  one more month to go with a dark universe hehe ... View more

Hi Michal,  to me it sounds like you want to create your own 3D measurement tool? Could you give us feedback on why you need to do this? We tried to design this tool so that people don't have to do all the work from scratch. Indeed, most of it is internal API and the actual calculation, the line generation and the labeling are not public and we don't really plan to make them. We use WebGL to render the 3D line and the labels are HTML elements. We considered adding options to change the color of the line. Would that help you already? Let me know what your requirements are, as I mentioned in the other post we are still working on the public API. ... View more

hmm now I wonder in which software you need to do this. If it happens to be the ArcGIS API for JavaScript, then in one month we will have this feature. So watch out for version 4.8. In the SceneViewer in ArcGIS Online we won't have that functionality yet. In any case, I'd be curious to hear about your use case for setting an image behind the scene. ... View more

Can you share a snippet to repro?  Popup shows in this sample: Add edges to a SceneLayer | ArcGIS API for JavaScript 4.7  ... View more

Did you pre-calculate the elevation in ArcGIS Pro and then published the lines? I guess you can also do that client-side by manipulating the z values in the polyline geometry, but it's probably better to save the computation for something else if they have values that never change. ... View more

The webGL report for your machine contains Major Performance Caveat set to true and it uses Software rendering: Unmasked renderer -> Google Swiftshader. It might be a problem with Chrome blacklisting your GPU. A possible solution could be to update the GPU driver on that machine. In general there might be certain GPUs that are blacklisted by browsers and when the user is exactly on such a machine the only thing you can do is to give him a warning message. In the API we catch this case and we don't create the view. I guess the safe thing to do is to catch when the view fails to create and send an error message to the user that they could try to update their driver. Practically in code you can do this: view.when(function() {    // View successfully loaded, show viewDiv }).catch(function(err) {    console.log(err);    // { message: "WebGL is required but not supported.", ...} });‍‍‍‍‍‍ Here is the whole sample where we show app developers how to catch these cases: ArcGIS API for JavaScript Sandbox  Hope that helps. ...

hmm I can't reproduce...can you open this link and send me a screenshot of the page? WebGL Report In case you don't want to post your setup here, feel free to send it to my email: rnicola@esri.com.  ... View more

ok, let me know more, that looks like we should be able to repro, but we haven't seen this behaviour so far. ... View more

Late to the party. Is this still an issue? If so, can you try with 4.7? And if it still doesn't work can you tell us what os are you using + version, which browser version? Maybe we can reproduce if we happen to have the same machine config. ... View more

Did I understand correctly that you want to visualize the buildings based on the status or type of the parcel that is used for the query?  The most performant way to achieve this would be to do a preprocessing in ArcGIS Pro: spatial join of buildings with polygons and add the corresponding attributes to the buildings. Now if your building data is "light" and you need to do this on the client side, a unique value renderer based on object ids might work too. I made a new example where I change the color of the buildings returned from the query based on the objectid. This is not optimal though, if there are thousands of unique values at some point the browser might run out of memory. SceneLayer polygon intersection with renderer  ...

Awesome, happy that it works. We'll also get it fixed to not choke on null values. Thanks for sharing. ... View more
