Can I draw a completely blue glowing polyline?

1. A concise explanation of the problem you’re experiencing.

I was trying to draw a glowing polyline using PolylineGlow, and I hope the whole polyline is all blue.

But I found that I can only change the color of the glowing edge while color of the middle part of polyline is still white.

Is there anyway to make a completely blue glowing polyline?

I have attached a picture for what I want to draw.

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

var czml = [

“path” : {

“material” : {

“polylineGlow” : {

“color” : {

“rgba” : [1, 228, 255, 255]


“glowPower”: 0.2



“width” : 30,

“leadTime” : 10,

“trailTime” : 1000,

“resolution” : 5

I was trying in the demo online:



Not out of the box with PolylineGlowMaterial, but you can try playing around with Fabric to create a custom material.
