Polyline materials in CZML

CesiumJS
1

Hello all,

i was trying to get some of the polyline materials added through CZML but with no luck.

I would like to add PolylineArrow material to a polyline.

I could't find anything on it in the CZML polyline description (https://github.com/AnalyticalGraphicsInc/cesium/wiki/CZML-Content)

but seeing that PolylineGlow and PolylineOutline are there (2 out of 3 from here https://github.com/AnalyticalGraphicsInc/cesium/wiki/Fabric#polyline-materials) i hoped maybe the documentation is not up to date and it was possible.

Still i tried to add a glow to a polyline and couldn't get it to work either. Here is my approach:

...
"polyline": {
    "width": 2,
    "material": {
          "solidColor": {
              "color": {
                "rgba": [255, 255, 255, 200]
              }
          },
          "polylineGlow":{
            "glowPower": 1.0,
              "color": {
                "rgba": [255, 0, 0, 200]
              }
          }
        },
        "positions": {
          "cartesian": [...]
...

additionaly tried to add:
"polylineArrow":{
              "color": {
                "rgba": [255, 0, 0, 200]
              }
          }
to the material, or just using the arrow as material.

Any information to if this even is implemented for CZML or what i am doing wrong would be greatly appreciated.

Kind regards,
Daniel

Unfortunately arrows aren’t supported yet in Cesium, but they should be trivial to add. Expect them in 1.7 on March 2nd, but I’ll update this message with details as soon as the feature goes into master.
