The polyline object aims at representing the line of visibility between a ground station and a satellite, but it has a builder that allows other usages if needed.

Example :

"polyline":{
      "width":1,
      "material":{
        "solidColor":{
          "color":{
            "rgba":[
              0,255,255,255
            ]
          }
        }
      }

Properties

availability - TimeInterval : Time interval when the polyline is displayed.

show - boolean : Whether or not the polyline is shown. default : false.

width - double : the width of the polyline, default : 1.0.

color - Color : The RGBA color of the cylinder. default : red = 0, green = 255, blue = 255, alpha = 255.

cesiumArctype - CesiumArcType : Defines the type of arc of the polyline, it can take several values :

• NONE - The arc is a straight line that does not conform to the surface of an ellipsoid.
• GEODESIC - The arc is a geodesic, which is the shortest path conforming to the surface of an ellipsoid.
• RHUMB - The arc is a rhumb line, or loxodrome, which is the path of constant heading conforming to the surface of an ellipsoid.
• default : NONE .

Build

The polyline object can be build with :

• An availability, a width, a color, a show :

Polyline polyline = new Polyline(availability, width, color, show);

• No arguments : (this method build a polyline with no availability)

Polyline polyline = new polyline();
