EllipseGraphics

new Cesium.EllipseGraphics(options)
DataSources/EllipseGraphics.js 52

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.
Name Type Description
options Object optional Object with the following properties:
Name Type Default Description
show Property true optional A boolean Property specifying the visibility of the ellipse.
semiMajorAxis Property optional The numeric Property specifying the semi-major axis.
semiMinorAxis Property optional The numeric Property specifying the semi-minor axis.
height Property 0 optional A numeric Property specifying the altitude of the ellipse relative to the ellipsoid surface.
heightReference Property optional A Property specifying what the height is relative to.
extrudedHeight Property optional A numeric Property specifying the altitude of the ellipse's extruded face relative to the ellipsoid surface.
extrudedHeightReference Property optional A Property specifying what the extrudedHeight is relative to.
rotation Property 0.0 optional A numeric property specifying the rotation of the ellipse counter-clockwise from north.
stRotation Property 0.0 optional A numeric property specifying the rotation of the ellipse texture counter-clockwise from north.
granularity Property Cesium.Math.RADIANS_PER_DEGREE optional A numeric Property specifying the angular distance between points on the ellipse.
fill Property true optional A boolean Property specifying whether the ellipse is filled with the provided material.
material MaterialProperty Color.WHITE optional A Property specifying the material used to fill the ellipse.
outline Property false optional A boolean Property specifying whether the ellipse is outlined.
outlineColor Property Color.BLACK optional A Property specifying the Color of the outline.
outlineWidth Property 1.0 optional A numeric Property specifying the width of the outline.
numberOfVerticalLines Property 16 optional A numeric Property specifying the number of vertical lines to draw along the perimeter for the outline.
shadows Property ShadowMode.DISABLED optional An enum Property specifying whether the ellipse casts or receives shadows from each light source.
distanceDisplayCondition Property optional A Property specifying at what distance from the camera that this ellipse will be displayed.
classificationType Property ClassificationType.BOTH optional An enum Property specifying whether this ellipse will classify terrain, 3D Tiles, or both when on the ground.
zIndex ConstantProperty 0 optional A property specifying the zIndex of the Ellipse. Used for ordering ground geometry. Only has an effect if the ellipse is constant and neither height or exturdedHeight are specified.
