Using agi_vector to draw line from position to the ground

CesiumJS
1

I need to draw a line from a plane flying over the ground, vertically to the ground. I'm trying to use agi_vertor but I can't see the line. This is the code:

"agi_vector":{
    "color":{
      "rgba":[
        255,255,0,255
      ]
    },
    "direction":{
      "spherical":[
        1,1,10
      ]
    },
    "minimumLengthInPixels":500,
    "show":true
  },

Thanks in advanced:

agi_vector is an extension to CZML and not implemented in Cesium. As far as I know, all of the agi_ extensions are only implemented in AGI’s commercial version of Cesium for aerospace and defense, https://cesium.agi.com/. That being said, there’s nothing stopping anyone from adding support for vectors and this extension in the open source version or any other fork of Cesium for that matter.

Disclaimer, I and many of the other Cesium committers work for AGI.

O.K, thanks for the answer. I can do it with PolyLine, with two references to original position and duplicated position with height modified to zero.
