Extend Cesium.PathGraphics to ground -


what i'd achieve 'extend path ground'. have 3d moving object path definition:

entity.path = new cesium.pathgraphics({resolution : 1,                 leadtime: 600,                 trailtime: 3600,                 material : new cesium.polylineglowmaterialproperty({                     glowpower : 0.1,                     color : cesium.color.yellow                 }),                 width : 10             });

something effect can achieve google earth: flight tracki guess means adding wall linked in way current path? redrawn every x seconds? how achieved cesium.js? direction tutorial or examples helpful.
