polyline and material in 3d + sensor projection in 2d

in 3D view, is it possible to cover a polyline with material (like polygon)?

In 2D view, is it possible to display a sensor projection on Earth?

Best regards

Materials for polylines was recently added to Cesium master and will be in the next release on May 1st.

We will eventually support sensor projects in 2D and Columbus view, but currently they are 3D only.

Hi there,

Any updates on sensor projection in 2D? I'd like to use it to show radio coverage of satellites with ground tracks - unless there's another way?
