animated polyline with image material -> Cesium Error

CesiumJS
1

Hi

I tried this:

var viewer = new Cesium.Viewer(‘cesiumContainer’);

var lon = -120;

var lat = 35;

function getPositions(){

lon += 0.05;

return Cesium.Cartesian3.fromDegreesArray([lon, 35, -125, 35]);

}

var redLine = viewer.entities.add({

polyline : {

positions : new Cesium.CallbackProperty(getPositions, false),

width : 5,

material : ‘…/images/Cesium_Logo_Color.jpg’

}

});

Can you help me - or is it a bug ?

Hello,

The Polyline doesn’t support an image material. You can see the supported material types in this example: http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Polyline.html&label=Geometries
