◆ computeDistanceSquaredToPosition() [1/3]

double CesiumGeospatial::BoundingRegion::computeDistanceSquaredToPosition	(	const Cartographic &	cartographicPosition,
		const glm::dvec3 &	cartesianPosition
	)		const

noexcept

Computes the distance-squared from a position to the closest point in this bounding region, when the longitude-latitude-height and ellipsoid-centered Cartesian coordinates of the position are both already known.

Parameters

cartographicPosition	The position as a longitude-latitude-height.
cartesianPosition	The position as ellipsoid-centered Cartesian coordinates.

Returns: The distance-squared from the position to the closest point in the bounding region.

◆ computeDistanceSquaredToPosition() [2/3]

double CesiumGeospatial::BoundingRegion::computeDistanceSquaredToPosition	(	const Cartographic &	position,
		const Ellipsoid &ellipsoid	CESIUM_DEFAULT_ELLIPSOID
	)		const

noexcept

Computes the distance-squared from a longitude-latitude-height position to the closest point in this bounding region.

Parameters

position	The position.
ellipsoid	The ellipsoid on which this region is defined.

Returns: The distance-squared from the position to the closest point in the bounding region.

◆ computeDistanceSquaredToPosition() [3/3]

double CesiumGeospatial::BoundingRegion::computeDistanceSquaredToPosition	(	const glm::dvec3 &	position,
		const Ellipsoid &ellipsoid	CESIUM_DEFAULT_ELLIPSOID
	)		const

noexcept

Computes the distance-squared from a position in ellipsoid-centered Cartesian coordinates to the closest point in this bounding region.

If the position cannot be converted into cartograpic coordinates for the given ellipsoid (because it is close to the center of the ellipsoid), then this function will return the squared distance between the given position and the closest point of the bounding box that is enclosed in this region.

Parameters

position	The position.
ellipsoid	The ellipsoid on which this region is defined.

Returns: The distance-squared from the position to the closest point in the bounding region.

◆ computeUnion()

BoundingRegion CesiumGeospatial::BoundingRegion::computeUnion	(	const BoundingRegion &	other,
		const CesiumGeospatial::Ellipsoid &ellipsoid	CESIUM_DEFAULT_ELLIPSOID
	)		const

noexcept

Computes the union of this bounding region with another.

Parameters

other The other bounding region.

Returns: The union.

◆ intersectPlane()

CesiumGeometry::CullingResult CesiumGeospatial::BoundingRegion::intersectPlane ( const CesiumGeometry::Plane & plane ) const

noexcept

Determines on which side of a plane the bounding region is located.

Parameters

plane The plane to test against.

Returns

The CesiumGeometry::CullingResult

Inside if the entire region is on the side of the plane the normal is pointing.
Outside if the entire region is on the opposite side.
Intersecting if the region intersects the plane.
