Members

color : Color

Get or Set the color
Example:
var skyline= new SuperMap3D.Skyline(scene);
var color = new SuperMap3D.Color(0, 1, 0);
 //Set color
 skyline.color = color;
 //Get color
 var value= skyline.color ;

direction : Number

Get or set the angle between the camera and true north. Unit: degree, value range 0-360.
Example:
var skyline= new SuperMap3D.Skyline(scene);
            // set direction
            skyline.direction = 1.0;
            //get direction
var value= skyline.direction ;

displayMode : Number

Get or set the display mode of lines and areas. When the value is 0, it is displayed as a line; when the value is 1, it is displayed as a surface. The default is line.
Default Value: 0

displayStyle : Number

Gets or sets the display mode of the skyline. DisplayMode.LINE indicates the line mode of the skyline, and DisplayMode.FACE indicates the face mode of the skyline.
Example:
var skyline= new SuperMap3D.Skyline(scene);
        //Set the display mode
        skyline.displayStyle = SuperMap3D.Skyline.displayMode.LINE;
        // get display mode
var value= skyline.displayStyle ;

ignoreGlobe : Boolean

Whether the earth's surface participates in the skyline analysis, the default value is false, which means participating, and when set to true, it means not participating.

lineWidth : Number

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

pitch : Number

Get or set 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 SuperMap3D.Skyline(scene);
        //Set pitch angle
        skyline. pitch = 1.0;
        //Get pitch angle
var value= skyline.pitch;

radius : Number

Get or set the skyline analysis radius, unit: meter. The default is -1.0, which means infinity.
Default Value: -1.0

viewPosition : Array

Get or Set the viewPosition
Example:
var skyline= new SuperMap3D.Skyline(scene);
        //Set the position of the observer
        skyline. viewPosition = [120, 40, 100];
        // Get the position of the observer
var value= skyline.viewPosition;
