I want to create a billboard to identify E and W directions of the building as shown below.
I have tried with the following code but the billboard doesn’t not parallel with the map and when I zoom out the billboard size is still the same as shown below.
Here is the code. Could anyone advise on this matter?
position: Cesium.Cartesian3.fromDegrees(longitude, latitude, parseInt(polylineHeight - 30)),
orientation: new Cesium.HeadingPitchRoll(0, 0, 0),
eyeOffset: new Cesium.Cartesian3(0.0, 0.0, 0.0)
