DtVector3D Class Reference

DtVector3D is a vector in earth-relative coordinates, e.g. east-north or heading-range. Its direction in space depends on where on the earth it is attached (like topocentric coordinates).

Constructor & Destructor Documentation

DtVector3D::DtVector3D

(

)

Constructor etc. intended for the script interface, not scripts themselves.

The constructor assumes that the vect holds north-east-down values.

DtVector3D::DtVector3D

(

const DtVector &

vect

)

DtVector3D::DtVector3D

(

const DtVector3D &

vect

)

DtVector3D::~DtVector3D

(

)

DtVector3D::DtVector3D	(	const double	north,
		const double	east,
		const double	down
	)

Constructor that is visible to scripts. Values in meters.

Member Function Documentation

DtVector3D& DtVector3D::operator=

(

const DtVector3D &

orig

)

DtVector DtVector3D::nedVector

(

)

const

void DtVector3D::setFromGeocentricVector	(	const DtVector &	geocVec,
		DtLocation3D &	origin
	)

This function sets the vector from a Geocentric vector. It uses the location3D to get an origin and the orientation of the NED coordinate system at that origin.

DtVector3D DtVector3D::makeCopy

(

)

const

The assignment operator and copy constructor above, are useful in the expected way for C++ code, but Lua just copies the references to objects, so a special copy function is needed.

DtString DtVector3D::objectType ( ) const

virtual

Inherited from DtAsciiSerializable.

Returns "DtVector3D"

Implements DtAsciiSerializable.

Reimplemented in DtVector2D.

DtString DtVector3D::serialize ( )

virtual

Returns a string serialized version of this class.

Implements DtAsciiSerializable.

bool DtVector3D::deserialize ( const DtString &  data )

virtual

Returns true if it could fill its members with the data contained in the string. False otherwise.

Implements DtAsciiSerializable.

static DtAsciiSerializable* DtVector3D::creator ( )

static

Returns a new object of this type with default values.

void DtVector3D::setNorthEastDown	(	const double	north,
		const double	east,
		const double	down
	)

Reset the vector from north, east, and down (in meters).

void DtVector3D::setBearingInclRange	(	const double	bearing,
		const double	inclination,
		const double	range
	)

Reset the vector from bearing, inclination (both in radians), and range in meters. Bearing is compass angle, i.e. clockwise from north. Note that the absolute value of the passed range is used.

double DtVector3D::getBearing

(

void

)

const

Set and get functions for different representations. Angles are in radians; all other parameters are in meters. All set functions set one dimension only, leaving the others unchanged.

double DtVector3D::getInclination

(

void

)

const

void setBearing(const double bearing);

double DtVector3D::getRange

(

void

)

const

void setInclination(const double inclination);

double DtVector3D::getNorth

(

void

)

const

void setRange(const double range);

double DtVector3D::getEast

(

void

)

const

void setNorth(double const north);

double DtVector3D::getDown

(

void

)

const

void setEast(double const east);

DtVector3D DtVector3D::getScaled

(

const double

scale

)

const

Vector modification functions. Return a new vector.

DtVector3D DtVector3D::getNegated

(

void

)

const

Components are north-east-down.

DtVector3D DtVector3D::getUnit

(

void

)

const

Components are north-east-down.

DtVector3D DtVector3D::addVector3D

(

const DtVector3D &

vec

)

const

Adds another vector3D.

DtVector3D DtVector3D::crossVector3D

(

const DtVector3D &

vec

)

const

Takes the cross product of given vector with this one.

double DtVector3D::dotVector3D

(

const DtVector3D &

vec

)

const

Takes the dot product of the given vector with this one.

DtVector3D DtVector3D::addOffset

(

const DtVectorOffset3D &

offset

)

const

Adds an offset to this vector. The (right, forward, up) offset is transformed to the direction of this vector (assuming no roll) before being added.

double DtVector3D::headingDiff

(

const DtVector3D &

vec

)

const

Determines the difference in headings from this vector to the given vector, in radians. Note that this is just in the horizontal plane.

DtVectorGeoc3D DtVector3D::makeVectorGeoc3DAtLoc

(

const DtLocation3D &

loc

)

const

Makes a geocentric vector equivalent to this vector at the given location on the earth.

bool DtVector3D::operator==

(

const DtVector3D &

)

const

Components are north-east-down.

bool DtVector3D::operator!= ( const DtVector3D &  orig ) const

inline

Components are north-east-down.
