Detailed Description

template<typename T>
class DtVectorT< T >

DtVectors represent vectors in 3-d space, X, Y, Z.

A DtVector is not a point. This class has no virtual functions, because we want the size of a DtVector to 3 * 8 (or 3*4 for DtVector32) bytes - so that you can make the same assumptions about it that we used to make about its size and layout. This is especially important in DtDcm, where we use an array of 3 DtVectors as the myRep. If DtVector had any virtual functions, there would be 4 bytes between vector reps.

Member Function Documentation

template<typename T>

void DtVectorT< T >::get	(	T &	x,
		T &	y,
		T &	z
	)		const

inline

get the x,y,z component of a Vector (faster than x(), y(), z() calls made separately)

template<typename T>

bool DtVectorT< T >::isNormalized ( ) const

inline

Returns true of the vector is Normalized.

template<typename T>

bool DtVectorT< T >::magnitudeIsZero ( ) const

inline

check if the magnitude of this vector is zero

template<typename T>

bool DtVectorT< T >::magnitudeIsZero ( double tolerance ) const

inline

check if the magnitude of this vector is zero, within the tolerance passed.

This tolerance is compared against each component of the vector, not the magnitude.

template<typename T>

double DtVectorT< T >::magnitudeSquared ( ) const

inline

Get the magnitude of the vector squared, i.e.

x^2 + y^2 + z^2

template<typename T>

void DtVectorT< T >::normalize ( )

inline

Normalize the vector; i.e., magnitude = 1.

inline

template<typename T>

DtVectorT< T >::operator T * ( )

inline

template<typename T>

int DtVectorT< T >::operator!= ( const DtVectorT< T > & vec ) const

inline

Get whether another vector does not equal this vector.

Warning: this operation calls operator== which tests floats for exact equality

inline

assignment operator

template<typename T>

int DtVectorT< T >::operator== ( const DtVectorT< T > & vec ) const
