Members

color : Color

Get or Set the color
Example:
var skyline= new Cesium.Skyline(scene);
var color = new Cesium.Color(0, 1, 0);
 //Set color
 skyline.color = color;
 //Get color
 var value= skyline.color ;

direction : Number

Gets or sets the angle between the camera and true north. Unit: degrees, the value range is 0-360.
Example:
var skyline= new Cesium.Skyline(scene);
//Set direction
skyline.direction = 1.0;
//Get directions
var value= skyline.direction ;

displayMode : Number

Gets or sets the display mode of the line and area. When the value is 0, it is displayed as a line; when the value is 1, it is displayed as a surface. The default value is line.
Default Value: 0

displayStyle : Number

Gets or sets the display mode of the skyline. DisplayMode.LINE represents the line mode of the skyline, and DisplayMode.FACE represents the surface mode of the skyline.
Example:
var skyline= new Cesium.Skyline(scene);
//Set the display mode
skyline.displayStyle = Cesium.Skyline.displayMode.LINE;
//Get display mode
var value= skyline.displayStyle ;

ignoreGlobe : Boolean

Whether the surface of the earth participates in the skyline analysis, the default value is false to indicate participation, when set to true, it means not to participate.

lineWidth : Number

Set the width of the skyline, the default is 1 pixel.
Default Value: 1

pitch : Number

Gets or sets the pitch angle of the camera, which is the angle between the camera direction and the water surface direction. Unit: Degree, the value range is 0-90.
Example:
var skyline= new Cesium.Skyline(scene);
//Set the pitch angle
skyline.pitch = 1.0;
//Get the pitch angle
var value= skyline.pitch;

radius : Number

Gets or sets the analysis radius of the skyline, in meters. The default value is -1.0, which means infinity.
Default Value: -1.0

viewPosition : Array

Get or Set the viewPosition
Example:
var skyline= new Cesium.Skyline(scene);
//Set the position of the observer
skyline.viewPosition   = [120, 40, 100];
//Get the position of the observer
var value= skyline.viewPosition;
