Ellipse
This page describes the possible content of a CZML document or stream. Please read CZML Structure for an explanation of how a CZML document is put together.
An ellipse, which is a closed curve on or above the surface of the Earth.
Interpolatable: no
show - Boolean
Whether or not the ellipse is shown.
Default: true
semiMajorAxis - Double - Required
The length of the ellipse's semi-major axis in meters.
semiMinorAxis - Double - Required
The length of the ellipse's semi-minor axis in meters.
height - Double
The altitude of the ellipse relative to the surface.
Default: 0.0
heightReference - HeightReference
The height reference of the ellipse, which indicates if height
is relative to terrain or not.
Default: NONE
extrudedHeight - Double
The altitude of the ellipse's extruded face relative to the surface.
extrudedHeightReference - HeightReference
The extruded height reference of the ellipse, which indicates if extrudedHeight
is relative to terrain or not.
Default: NONE
rotation - Double
The angle from north (counter-clockwise) in radians.
Default: 0.0
stRotation - Double
The rotation of any applied texture coordinates.
Default: 0.0
granularity - Double
The sampling distance, in radians.
Default: π / 180.0
fill - Boolean
Whether or not the ellipse is filled.
Default: true
material - Material
The material to use to fill the ellipse.
Default: solid white
outline - Boolean
Whether or not the ellipse is outlined.
Default: false
outlineColor - Color
The color of the ellipse outline.
Default: black
outlineWidth - Double
The width of the ellipse outline.
Default: 1.0
numberOfVerticalLines - Integer
The number of vertical lines to use when outlining an extruded ellipse.
Default: 16
shadows - ShadowMode
Whether or not the ellipse casts or receives shadows.
Default: DISABLED
distanceDisplayCondition - DistanceDisplayCondition
The display condition specifying at what distance from the camera this ellipse will be displayed.
classificationType - ClassificationType
Whether a classification affects terrain, 3D Tiles, or both.
Default: BOTH
zIndex - Integer
The z-index of the ellipse, used for ordering ground geometry. Only has an effect if the ellipse is constant, and height
and extrudedHeight
are not specified.
Default: 0
