Detailed Description

mathematical 3d-vector.

This class is directly written to and read from files.

It may only contain the three coordinates, and nothing more that requires storage memory, like virtual functions.

Constructor & Destructor Documentation

Vector::Vector ( )

Vector::Vector ( const Vector & p )

ctor: copy from other vector

Vector::Vector ( Vector & v1, Vector & v2 )

ctor: be the normal vector to those

Vector::Vector ( rvfloat x, rvfloat y, rvfloat z )

ctor: spec. x,y,z

---

Member Function Documentation

bool Vector::isnull ( ) const [inline]

rvfloat Vector::length ( void ) const

rvfloat Vector::lengthXZ ( void ) const

bool Vector::normalize ( void )

tries to rescale a vector to have length 1.0 Returns: true if successfull false if vector is too small for rescaling

bool Vector::normalizeXZ ( void )

Vector Vector::operator * ( Vector & p )

cross product (result is a (not the) normal vector to this and the argument vector)

Vector Vector::operator * ( rvfloat scalefac )

scales a vector by scalefac

bool Vector::operator!= ( const Vector & p ) const

Vector Vector::operator+ ( Vector & p )

Vector Vector::operator- ( Vector & p )

Vector Vector::operator/ ( rvfloat scalediv )

scales a vector by scalediv

bool Vector::operator<= ( const Vector & p ) const

Is a x1<x2 && y1<y2 && z1<z2

bool Vector::operator== ( const Vector & p ) const

equal op. Does return true for close vectors, too

rvfloat & Vector::operator[] ( int i ) [inline]

bool Vector::perp ( const Vector & v ) const [inline]

true if perpendicular to other vector (nullvector is always!)

bool Vector::right_perp_triplet ( Vector & v1, Vector & v2, Vector & v3 ) [static]

true if v1,v2 and v3 (in this order) form a right-handed perpendicular triplet

void Vector::rotate_right_xz ( void )

rotates the vector by 90 degrees in the X-Z-plane

rvfloat Vector::scalarprod ( const Vector & v ) const

scalar product

rvfloat Vector::scalarprod_xz ( const Vector & v ) const

scalar product ignoring Y

bool Vector::unidir ( const Vector & v ) const

true if parallel and unidirectional to other vector (never to nullvector)

rvfloat Vector::x ( rvfloat f )

rvfloat Vector::x ( void ) const

rvfloat & Vector::x ( void )

rvfloat Vector::y ( rvfloat f )

rvfloat Vector::y ( void ) const

rvfloat & Vector::y ( void )

rvfloat Vector::z ( rvfloat f )

rvfloat Vector::z ( void ) const

rvfloat & Vector::z ( void )
