Member Function Documentation

§ Zero()

void Zero ( )
inherited

Sets the coordinates as zero.

§ Get()

void Get ( double *  p) const
inherited

Puts the coordinate values into the array.

§ Set() [1/3]

void Set ( const double *  p)
inherited

Sets the coordinates using the values in the given array.

§ Set() [2/3]

void Set ( const double &  v)
inherited

Sets all coordinates using the given value.

§ Set() [3/3]

void Set ( const double &  _x,
const double &  _y 
)
inherited

Sets the coordinates using the given values.

§ LengthSquared()

double LengthSquared ( ) const
inherited

Returns the square of the length. Effectively, this is the dot product of the vector with itself.

§ Length()

double Length ( ) const
inherited

Returns the length of the vector.

§ Normalize()

void Normalize ( )
inherited

Normalizes the vector, such that its length becomes 1.

§ GetNormalized()

Point2 GetNormalized ( ) const
inherited

Returns a normalized copy of the vector.

§ Sum()

double Sum ( ) const
inherited

Returns the sum of its components.

§ IsZero()

bool IsZero ( ) const
inherited

Returns true if all components are exactly zero.

§ Min()

double Min ( ) const
inherited

Returns the square of the length. Effectively, this is the dot product of the vector with itself.

§ Max()

double Max ( ) const
inherited

Returns the square of the length. Effectively, this is the dot product of the vector with itself.

§ MinID()

int MinID ( ) const
inherited

Returns the square of the length. Effectively, this is the dot product of the vector with itself.

§ MaxID()

int MaxID ( ) const
inherited

Returns the square of the length. Effectively, this is the dot product of the vector with itself.

§ Clamp()

void Clamp ( const double &  minValue,
const double &  maxValue 
)
inherited

Converts all negative components to positive values.

§ ClampMin()

void ClampMin ( const double &  v)
inherited

Converts all negative components to positive values.

§ ClampMax()

void ClampMax ( const double &  v)
inherited

Converts all negative components to positive values.

§ Abs()

void Abs ( )
inherited

Converts all negative components to positive values.

§ Cross()

double Cross ( const Point2< double > &  p) const
inherited

Cross product.

§ operator^()

double operator^ ( const Point2< double > &  p) const
inherited

Cross product operator.

§ Dot()

double Dot ( const Point2< double > &  p) const
inherited

Dot product.

§ operator%()

double operator% ( const Point2< double > &  p) const
inherited

Dot product operator.
