CZML Ellipse
- "ellipse":
{ "semiMajorAxis": <number>, "semiMinorAxis": <number>, "material": { "solidColor": { "color": { "rgba": [r,g,b,a] } } }, "height": <number>, "extrudedHeight": <number>, "rotation": <radians>, "fill": true|false, "outline": true|false, "outlineColor": { "rgba": [r,g,b,a] }, "show": true|false } — a closed curve centered on the
entity's "position". "semiMajorAxis"/"semiMinorAxis" are in meters, measured from center to edge.
- A circle is an ellipse with equal "semiMajorAxis" and "semiMinorAxis".
- "rotation" is the angle from north, counter-clockwise, in radians.
- Set "extrudedHeight" (with "height" as the base) to give the ellipse volume above the ground.
Example: a circle, an outlined ellipse, and a rotated extruded ellipse
