Ellipse

AltitudeMode used by movable object

Indicates the shape's normal (non-highlight) attributes.

Base altitude level of shape sides. Is dependent on altitudeMode. Ground level by default.

The ellipse's geographic center position.

The ellipse's heading clockwise from North. When ellipse's heading is 0.0, the semi-major axis points East and the semi-minor axis points North. Headings other than 0.0 rotate the axes about the ellipse's center position, while retaining the axes relative relationship to one another.

Indicates the shape's highlight attributes.

Determines whether surface shape should be batched to terrain textures cache or single color attachment. Set this flag to true when shape editing is intended and to false when editing is finished.

Draw sides of the shape which extend from the defined position and altitude to baseAltitude level.

Determines whether this shape's geometry follows the terrain surface or is fixed at a constant altitude.

Indicates whether the shape is highlighted.

true when this shape's referencePosition coincides with where the user actually sees the shape (Placemark, Label, sightlines — the reference is the rendered location). false for shapes whose reference is computed from extended geometry and may sit far from where the user grabbed (Polygon centroid, Path centroid, Mesh).

Optional lambda to control current shape visibility based on its attributes and frame render context

The ellipse's radius perpendicular to it's heading, in meters. When the ellipse's heading is 0.0, the semi-major axis points East.

Sets the maximum number of angular intervals that may be used to approximate this ellipse's on screen.
Ellipse may use a minimum number of intervals to ensure that its appearance on screen at least roughly approximates the ellipse's shape. When the specified number of intervals is too small, it is clamped to an implementation-defined minimum number of intervals.
Ellipse may require that the number of intervals is an even multiple of some integer. When the specified number of intervals does not meet this criteria, the next smallest integer that meets ellipse's criteria is used instead.

Maximum number of intermediate edge intervals across a half-equator (PI radians) of arc. Per-edge subdivision count is scaled by edge length: steps = round(maximumNumEdgeIntervals * distanceRadians / PI), then further adjusted by polarThrottle near the poles for surface shapes. 3D shapes use the unthrottled count. A value of 0 disables intermediate vertex generation.

The maximum pixels a single edge interval will span before the number of intervals is increased. Increasing this value will make ellipses appear coarser.

The ellipse's radius parallel to it's heading, in meters. When the ellipse's heading is 0.0, the semi-minor axis points North.

Pole-throttle factor: higher values shrink the subdivision step near ±90° latitude so the straight 2D lon/lat segments between samples more closely follow the true great-circle path. A value of 0 disables throttling (uniform step).

A position associated with the object that indicates its aggregate geographic position. The chosen position varies among implementers of this interface. For objects defined by a list of positions, the reference position is typically the first position in the list. For symmetric objects the reference position is often the center of the object. In many cases the object's reference position may be explicitly specified by the application.

Azimuth of the first arc vertex of a partial ellipse (sector / pie slice), measured clockwise from North in the ellipse's local frame. Combined with sweepAngle, it defines the angular extent of the visualized sector. Default is ZERO.

Clockwise angular sweep of a partial ellipse (sector / pie slice), starting at startAzimuth. When 0° or 360° the ellipse renders as a closed shape (default behavior). Otherwise the geometry becomes a wedge: the perimeter spans `startAzimuth`, `startAzimuth + sweepAngle` and is closed through the ellipse center, producing a pie-slice fill plus two radial outline edges from the center to the arc endpoints.

Apply simplestyle stroke / fill / stroke-width to a Path or Polygon's attributes. Writes outline / interior color only when there's an explicit value to apply — either the feature's stroke / fill property OR a non-null defaultLineColor / defaultFillColor. With both null (the default), an absent property leaves the renderable's existing color alone — important when the layer's shapeAttributes supplied an intentional template colour at construction time (e.g. Shapefile's translucent blue) that would otherwise be clobbered by auto-style.

Move the shape over the globe's surface while maintaining its original azimuth, its orientation relative to North.
