polylines in 3d from czml, or polygon outline control


after much searching i’m gonna concede.

we have a workflow that simulates the draping of polygons and points over the terrain using Cesium.sampleTerrain()… it reads features coming in from czml and modifies the positions’ z values before adding them to the map.

This works fine for polygons and points, but the polylines never seem to respect the z-component of their posisitions.

in the sandbox there’s an eample of a polyline being 3d, so i’m sure we’re doing something wrong.

alternatively, if there was a way to style the outline of a polygon, this wouldn’t be neccessary.

are there any examples of CZML where a polyine is shown in 3D?
