Fan, SensorConic, Vector&PolylineVolume in CZML

CesiumJS
1

Hi,
I wanna to know whether the PolylineVolume geometry will be included in the CZML specification in the future?

And I am little curious about the Fan, SensorConic, Vector geometries. I want to know how to draw them with CZML, could someone provide me some relevant demo?

And I’ve tried to draw a Fan geometry, just like this.

This is my code snippet and I have no idea what’s wrong with it… It just shows nothing on Cesium.

Could someone help me to fix it out?Thanks very much!

Hello,

I don’t think the polyline volume geometry will be added to CZML any time soon. There are some improvements I would like to make for that geometry first.

Regarding the other types you listed below, those are only available in “Cesium Pro”, a library AGI built on top of Cesium to include those specialized features.

You can learn more about that package on this page: https://cesium.agi.com/products/cesium-pro/default.aspx

Best,

Hannah

Also note that because they are non-standard, fan, vector, etc. are all vendor-prefixed in CZML. These properties are listed at the bottom of the list in the CZML documentation: https://github.com/AnalyticalGraphicsInc/czml-writer/wiki/Packet

Thanks for the advice.
I’ll look into the documentation once again.
