I'd like to display polygons which are not 'level', but which follow the
terrain with a specified offset. for example, it would be a polygon, but
not at say 1500ft above mean sea level, but at 1500ft above ground level.
as Cesium already have a terrain / elevation map feature built in, I
wonder if there is a simple or not-so-simple way to achieve this?
basically I'd need the same, but with no textures but a simple
see-through color, and vertically offset.
