Detailed Description

template<typename T, int Size>
class vtkVector< T, Size >

templated base type for storage of vectors.

This class is a templated data type for storing and manipulating fixed size vectors, which can be used to represent two and three dimensional points. The memory layout is a contiguous array of the specified type, such that a float[2] can be cast to a vtkVector2f and manipulated. Also a float[6] could be cast and used as a vtkVector2f[3].

Constructor & Destructor Documentation

vtkVector() [1/3]

template<typename T , int Size>

vtkVector< T, Size >::vtkVector ( )

default

vtkVector() [2/3]

template<typename T , int Size>

vtkVector< T, Size >::vtkVector ( const T &  scalar )

inlineexplicit

Initialize all of the vector's elements with the supplied scalar.

Definition at line 104 of file vtkVector.h.

vtkVector() [3/3]

template<typename T , int Size>

vtkVector< T, Size >::vtkVector ( const T *  init )

inlineexplicit

Initialize the vector's elements with the elements of the supplied array.

Note that the supplied pointer must contain at least as many elements as the vector, or it will result in access to out of bounds memory.

Definition at line 114 of file vtkVector.h.

Member Function Documentation

SquaredNorm()

template<typename T , int Size>

T vtkVector< T, Size >::SquaredNorm ( ) const

inline

Get the squared norm of the vector.

Definition at line 123 of file vtkVector.h.

Norm()

template<typename T , int Size>

double vtkVector< T, Size >::Norm ( ) const

inline

Get the norm of the vector, i.e.

its length.

Definition at line 137 of file vtkVector.h.

Normalize()

template<typename T , int Size>

double vtkVector< T, Size >::Normalize ( )

inline

Normalize the vector in place.

Returns

The length of the vector.

Definition at line 144 of file vtkVector.h.

Normalized()

template<typename T , int Size>

vtkVector< T, Size > vtkVector< T, Size >::Normalized ( ) const

inline

Return the normalized form of this vector.

Returns

The normalized form of this vector.

Definition at line 165 of file vtkVector.h.

Dot()

Definition at line 177 of file vtkVector.h.

Cast()

template<typename T , int Size>

template<typename TR >

vtkVector< TR, Size > vtkVector< T, Size >::Cast ( ) const

inline

Cast the vector to the specified type, returning the result.
