Detailed Description

Defines an orthogonal coordindate basis in ECEF space.

EcefTangentBasis defines an orthogonal coordinate basis located at a point in ECEF (Earth-centred, Earth-fixed) space. The "up" direction is constrained to be perpendicular to the (earth-) sphere's surface - so are radial from the sphere centre. The "right" and "forward" directions lie on a plane that is tangential to the earth-sphere surface.

Constructor & Destructor Documentation

Eegeo::Space::EcefTangentBasis::EcefTangentBasis	(	const dv3 &	pointEcef,
		const v3 &	heading
	)

Construct from point and heading (forward) direction.

Parameters

pointEcef	the origin of the coordinate basis, in ECEF coordinates
heading	direction. This is projected onto the sphere-tangent plane passing through pointEcef, to become the Forward direction

Member Function Documentation

EcefTangentBasis Eegeo::Space::EcefTangentBasis::CreateFromMortonKey ( const Eegeo::Streaming::MortonKey &  key )

static

Creates an ecef tangent basis for a morton key.

Parameters

key.	The morton key for which the ecef tangent basis is to be constructed

void Eegeo::Space::EcefTangentBasis::Set	(	const dv3 &	pointEcef,
		const v3 &	heading
	)

Set from point and heading (forward) direction.

Parameters

pointEcef	the origin of the coordinate basis, in ECEF coordinates
heading	direction. This is projected onto the sphere-tangent plane passing through pointEcef, to become the Forward direction
