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.

Gets or sets the ClassificationType Property specifying whether this ellipse will classify terrain, 3D Tiles, or both when on the ground.
默认值: ClassificationType.BOTH
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.
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.
默认值: HeightReference.NONE
Gets or sets the boolean Property specifying whether the ellipse is filled with the provided material.
默认值: true
Gets or sets the numeric Property specifying the angular distance between points on the ellipse.
默认值: {CesiumMath.RADIANS_PER_DEGREE}
Gets or sets the numeric Property specifying the altitude of the ellipse.
默认值: 0.0
Gets or sets the Property specifying the HeightReference.
默认值: HeightReference.NONE
Gets or sets the Property specifying the material used to fill the ellipse.
默认值: Color.WHITE
Gets or sets the numeric Property specifying the number of vertical lines to draw along the perimeter for the outline.
默认值: 16
Gets or sets the Property specifying whether the ellipse is outlined.
默认值: false
Gets or sets the Property specifying the Color of the outline.
默认值: Color.BLACK
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}.

默认值: 1.0
Gets or sets the numeric property specifying the rotation of the ellipse counter-clockwise from north.
默认值: 0
Gets or sets the numeric Property specifying the semi-major axis.
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.
默认值: ShadowMode.DISABLED
Gets or sets the boolean Property specifying the visibility of the ellipse.
默认值: true
Gets or sets the numeric property specifying the rotation of the ellipse texture counter-clockwise from north.
默认值: 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
默认值: 0
