Member Function Documentation

angle()

double GKVector::angle

(

const GKVector &

v2

)

const

It returns the smallest angle between "this" and "v2" vectors in radians

angleWithTheHorizontal()

double GKVector::angleWithTheHorizontal

(

)

const

It returns the angle this vector makes with the horizontal in radians between - GKPI and GKPI. Note: The horizontal is interpreted as the vector (1.0, 0.0)

crossProduct()

GKVector GKVector::crossProduct

(

const GKVector &

v2

)

const

Returns the resulting vector of calculating the vectorial product between this vector and v2

dotProduct()

double GKVector::dotProduct

(

const GKVector &

v2

)

const

Returns the scalar product between to vectors

fullAngle()

double GKVector::fullAngle

(

const GKVector &

v2

)

const

It returns the angle between "this" and "v2" vectors in radians (0 - 2PI)

getLength()

double GKVector::getLength

(

)

const

Gets the vector length calculated using the points or coordinates defined for the vector.

getX()

GKCoord GKVector::getX

(

)

const

Gets the x coordinate of this vector.

getY()

GKCoord GKVector::getY

(

)

const

Gets the y coordinate of this vector.

getZ()

GKCoord GKVector::getZ

(

)

const

Gets the z coordinate of this vector.

normalize()

void GKVector::normalize

(

)

Normalizes this vector changing its length to 1.0 meter and normalizing the x,y and z coordinates
