Cesium labels on a polyline (similiar to a textpath)?

CesiumJS
1

I would like to recreate bent/ curved country labels spanning the area of the country.

In d3 (or SVG) I can construct a polyline and then use a textpath to have text along it. Example: https://www.w3.org/TR/SVG2/images/text/text-path-startoffset.svg

Is it possible in Cesium to do something similar?

In Leaflet it is implemented like that: http://makinacorpus.github.io/Leaflet.TextPath/

Sorry, but this is not something currently included in Cesium. We have an issue written up to add support for aligning a label with an axis here: https://github.com/AnalyticalGraphicsInc/cesium/issues/4215

Best,

Hi Hannah!

Is there any chance I could implement the TextPath manually? Is there any example of a svg pane mapped on the cesium globe which I can access and modify?

Sorry, I don’t think we have any examples that would help for implementing this.
But if you wanted to take a stab at it, you’ll need to modify the Label class: https://github.com/AnalyticalGraphicsInc/cesium/blob/master/Source/Scene/Label.js

And you can find information about cloning and building the code base here: https://github.com/AnalyticalGraphicsInc/cesium/tree/master/Documentation/Contributors/BuildGuide

If you get something working, please let me know! We would love the contribution back.

Best,

Hannah
