Members with descriptions

float x, y, z, w

Description:

CL_Vector(

float x = 0.0,
float y = 0.0,
float z = 0.0,
float w = 1.0)

Description:

Constructor that initializes a vector

CL_Vector(

const CL_Vector &other)

Parameters:
other - vector to copy

Description:

Copy Constructor

float norm()

Description:

Returns the (euclid) norm of the vector. It only uses the x,y,z ordinates! not using w component

Return value:

the euclid norm of the vector (in R^3)

void normalize()

Description:

Normalizes the vector (not taking into account the w ordinate!) not using w component

float dot(

const CL_Vector& v)

Parameters:
v - other vector 

Description:

Returns the dot product of the current vector and v

Return value:

the dot product of the two vectors

float angle(

const CL_Vector& v)

Parameters:
v - other vector 

Description:

Returns the angle between the current vector and v

Return value:

the angle between the two vectors

CL_Vector cross(

const CL_Vector& v)

Parameters:
v - other vector 

Description:

Returns the cross product of the current vector and v

Return value:

the cross product of the two vectors

CL_Vector rotate(

float angle,
const CL_Vector& a)

Parameters:
angle - angle to rotate
a - rotation axis

Description:

Returns the current vector rotated around vector a and angle angle

Return value:

the rotated vector

void round()

Description:

rounds all components

CL_Vector operator * (

float s)

Description:

Scalar product (vector * scalar)

Return value:

the scalar product

void operator +=(

const CL_Vector& v)

Description:

+= operator

void operator -=(

const CL_Vector& v)

Description:

-= operator

void operator *=(

float s)

Description:

*= operator (scalar multiplication)

CL_Vector operator + (

const CL_Vector& v)

Description:

+ operator

CL_Vector operator - (

const CL_Vector& v)

Description:

- operator

CL_Vector operator - ()

Description:

unary - operator

CL_Vector& operator = (

const CL_Vector& v)

Description:

assignment operator

int operator ==(

CL_Vector& v)

Parameters:
v - other vector

Description:

Returns true if current vector equals v

Return value:

true if v equals the current vector, false otherwise

int operator !=(

CL_Vector& v)

Parameters:
v - other vector

Description:

Returns false if current vector equals v

Return value:

false if v equals the current vector, true otherwise

float& operator [](

int n)

Parameters:
n - number of ordinate (starting with 0)

Description:

Returns reference to n-th ordinate (0. == x, 1. == y, ...)

Return value:

reference to the n-th ordinate
