How to Set the rotation info on the stream service using the renderer

[kishorekumar1]

Hi,

     I have a stream service which has a particular field which represents the angle(heading) of the feature. Now, I want to use that field values as the rotation angle for all the stream service features using the renderer. In 3.15 javascript version there is a method setRotationInfo() in Class SimpleRederer but this method is missing in 4.0 JavaScript beta. So, how can I set the rotation info for the renderer so that it can be levied on the stream service.

Regards,

Kishore Kumar

I believe this isn't available yet in the 4.0 API beta. By digging around the objects, the Rotation Info object is still present in the renderer as it was before, but isn't documented and probably isn't implemented or ready for prime-time. It should show up in one of the future releases, keep an eye on our blog for when it does.

(Disclaimer, I don't work for the API team)

The rotation visual variable will be available in 4.0 final so you should be able to do something like this:

var rotRenderer = new SimpleRenderer({
  symbol: picSym,
  visualVariables: [{
    type: "rotation",
    field: "heading",
    rotationType: "geographic"
  }]
});

var streamLayer = new StreamLayer({
  url: svcUrl,
  renderer: rotRenderer,
});

Hi Kristian,

                    Now, I am using latest release of ArcGIS api for javascript 4.0.Using the above rotation code I have achieved the rotation of the features of the stream service in 2D view.But I failed to achieve this on the scene view.Please guide me in this regard.

Rotation is not supported in SceneView for 4.0. We're discussing plans for support in a future release.

[KrishV]

is this supported in current version. If yes, please help me with code snippet how to achieve rotation in Scene View for Stream Service.

I'm trying to rotate picture marker symbol for Stream Service.

Thanks,

Krish

SceneView supports rotation if a symbol contains an ObjectSymbol3DLayer is used, so PictureMarkerSymbols aren't supported. The documentation states the following limitations:

In a SceneView rotation visual variables are not supported with marker symbols, text symbols, 3D icon symbol layers and 3D text symbol layers.
