CesiumGeospatial::SimplePlanarEllipsoidCurve Class Referencefinal

Produces points on an ellipse that lies on a plane that intersects the center of the earth and each of the input coordinates. The height above the surface at each point along the curve will be a linear interpolation between the source and destination heights. More...

◆ fromEarthCenteredEarthFixedCoordinates()

static std::optional< SimplePlanarEllipsoidCurve > CesiumGeospatial::SimplePlanarEllipsoidCurve::fromEarthCenteredEarthFixedCoordinates ( const Ellipsoid & ellipsoid,
const glm::dvec3 & sourceEcef,
const glm::dvec3 & destinationEcef )
static

Creates a new instance of SimplePlanarEllipsoidCurve from a source and destination specified in Earth-Centered, Earth-Fixed coordinates.

Parameters
ellipsoidThe ellipsoid that the source and destination positions are relative to.
sourceEcefThe position that the path will begin at in ECEF coordinates.
destinationEcefThe position that the path will end at in ECEF coordinates.
Returns
An optional type containing a SimplePlanarEllipsoidCurve object representing the generated path, if possible. If it wasn't possible to scale the input coordinates to geodetic surface coordinates on a WGS84 ellipsoid, this will return std::nullopt instead.

◆ fromLongitudeLatitudeHeight()

static std::optional< SimplePlanarEllipsoidCurve > CesiumGeospatial::SimplePlanarEllipsoidCurve::fromLongitudeLatitudeHeight ( const Ellipsoid & ellipsoid,
const Cartographic & source,
const Cartographic & destination )
static

Creates a new instance of SimplePlanarEllipsoidCurve from a source and destination specified in cartographic coordinates (Longitude, Latitude, and Height).

Parameters
ellipsoidThe ellipsoid that these cartographic coordinates are from.
sourceThe position that the path will begin at in Longitude, Latitude, and Height.
destinationThe position that the path will end at in Longitude, Latitude, and Height.
Returns
An optional type containing a SimplePlanarEllipsoidCurve object representing the generated path, if possible. If it wasn't possible to scale the input coordinates to geodetic surface coordinates on a WGS84 ellipsoid, this will return std::nullopt instead.

◆ getPosition()

glm::dvec3 CesiumGeospatial::SimplePlanarEllipsoidCurve::getPosition ( double percentage,
double additionalHeight = 0.0 ) const

Samples the curve at the given percentage of its length.

Parameters
percentageThe percentage of the curve's length to sample at, where 0 is the beginning and 1 is the end. This value will be clamped to the range [0..1].
additionalHeightThe height above the earth at this position will be calculated by interpolating between the height at the beginning and end of the curve based on the value of percentage. This parameter specifies an additional offset to add to the height.
Returns
The position of the given point on this curve in Earth-Centered Earth-Fixed coordinates.
