EllipseGraphics

new Cesium.EllipseGraphics(options)

Describes an ellipse defined by a center point and semi-major and semi-minor axes. The ellipse conforms to the curvature of the globe and can be placed on the surface or at altitude and can optionally be extruded into a volume. The center point is determined by the containing Entity.

Members

classificationType : Property|undefined

Gets or sets the ClassificationType Property specifying whether this ellipse will classify terrain, 3D Tiles, or both when on the ground.
Default Value: ClassificationType.BOTH

readonly definitionChanged : Event

Gets the event that is raised whenever a property or sub-property is changed or modified.

distanceDisplayCondition : Property|undefined

Gets or sets the DistanceDisplayCondition Property specifying at what distance from the camera that this ellipse will be displayed.

extrudedHeight : Property|undefined

Gets or sets the numeric Property specifying the altitude of the ellipse extrusion. Setting this property creates volume starting at height and ending at this altitude.

extrudedHeightReference : Property|undefined

Gets or sets the Property specifying the extruded HeightReference.
Default Value: HeightReference.NONE
Gets or sets the boolean Property specifying whether the ellipse is filled with the provided material.
Default Value: true
Gets or sets the numeric Property specifying the angular distance between points on the ellipse.
Default Value: {CesiumMath.RADIANS_PER_DEGREE}
Gets or sets the numeric Property specifying the altitude of the ellipse.
Default Value: 0.0

heightReference : Property|undefined

Gets or sets the Property specifying the HeightReference.
Default Value: HeightReference.NONE
Gets or sets the Property specifying the material used to fill the ellipse.
Default Value: Color.WHITE

numberOfVerticalLines : Property|undefined

Gets or sets the numeric Property specifying the number of vertical lines to draw along the perimeter for the outline.
Default Value: 16
Gets or sets the Property specifying whether the ellipse is outlined.
Default Value: false

outlineColor : Property|undefined

Gets or sets the Property specifying the Color of the outline.
Default Value: Color.BLACK

outlineWidth : Property|undefined

Gets or sets the numeric Property specifying the width of the outline.

Note: This property will be ignored on all major browsers on Windows platforms. For details, see (@link https://github.com/CesiumGS/cesium/issues/40}.

Default Value: 1.0
Gets or sets the numeric property specifying the rotation of the ellipse counter-clockwise from north.
Default Value: 0

semiMajorAxis : Property|undefined

Gets or sets the numeric Property specifying the semi-major axis.

semiMinorAxis : Property|undefined

Gets or sets the numeric Property specifying the semi-minor axis.
Get or sets the enum Property specifying whether the ellipse casts or receives shadows from light sources.
Default Value: ShadowMode.DISABLED
Gets or sets the boolean Property specifying the visibility of the ellipse.
Default Value: true
Gets or sets the numeric property specifying the rotation of the ellipse texture counter-clockwise from north.
Default Value: 0
Gets or sets the zIndex Property specifying the ellipse ordering. Only has an effect if the ellipse is constant and neither height or extrudedHeight are specified
Default Value: 0
