EarthCenteredEarthFixedToLongitudeLatitudeHeight()

static partial double3 CesiumForUnity.CesiumWgs84Ellipsoid.EarthCenteredEarthFixedToLongitudeLatitudeHeight ( double3 earthCenteredEarthFixed )

static

Convert Earth-Centered, Earth-Fixed (ECEF) coordinates to longitude, latitude, and height.

Parameters

earthCenteredEarthFixed

The ECEF coordinates in meters.

Returns

The longitude (X) and latitude (Y) are in degrees. The height (Z) is in meters above the ellipsoid, and should not be confused with a geoid, orthometric, or mean sea level height.

GeodeticSurfaceNormal()

static partial double3 CesiumForUnity.CesiumWgs84Ellipsoid.GeodeticSurfaceNormal ( double3 earthCenteredEarthFixed )

static

Computes the normal of the plane tangent to the surface of the ellipsoid at the provided Earth-Centered, Earth-Fixed position.

Parameters

earthCenteredEarthFixed

The ECEF position in meters.

Returns

The normal at the ECEF position

GetMaximumRadius()

static double CesiumForUnity.CesiumWgs84Ellipsoid.GetMaximumRadius ( )

inlinestatic

Gets the maximum radius of the ellipsoid in any dimension.

Returns

The maximum radius of the ellipsoid.

Definition at line 23 of file CesiumWgs84Ellipsoid.cs.

GetMinimumRadius()

static double CesiumForUnity.CesiumWgs84Ellipsoid.GetMinimumRadius ( )

inlinestatic

Gets the minimum radius of the ellipsoid in any dimension.

Returns

The minimum radius of the ellipsoid.

Definition at line 32 of file CesiumWgs84Ellipsoid.cs.

GetRadii()

static partial double3 CesiumForUnity.CesiumWgs84Ellipsoid.GetRadii ( )

static

Gets the radii of the ellipsoid in its x-, y-, and z-directions.

Returns

The radii of the ellipsoid in its x-, y-, and z-directions.

LongitudeLatitudeHeightToEarthCenteredEarthFixed()

static partial double3 CesiumForUnity.CesiumWgs84Ellipsoid.LongitudeLatitudeHeightToEarthCenteredEarthFixed ( double3 longitudeLatitudeHeight )

static

Convert longitude, latitude, and height to Earth-Centered, Earth-Fixed (ECEF) coordinates.

Parameters

longitudeLatitudeHeight

The longitude (X) and latitude (Y) are in degrees. The height (Z) is in meters above the ellipsoid, and should not be confused with a geoid, orthometric, or mean sea level height.

Returns

The ECEF coordinates in meters.

ScaleToGeodeticSurface()

static partial? double3 CesiumForUnity.CesiumWgs84Ellipsoid.ScaleToGeodeticSurface ( double3 earthCenteredEarthFixed )

static

Scale the given Earth-Centered, Earth-Fixed position along the geodetic surface normal so that it is on the surface of the ellipsoid.

If the position is at the center of the ellipsoid, the result will be null.

Parameters

earthCenteredEarthFixed

The ECEF position in meters.

Returns

The scaled position, or null if the position is at the center of the ellipsoid.
