Detailed Description

template<unsigned D, typename N = double>
class VecMath::Vector< D, N >

Vector<D, N>: a D-dimensional vector of numbers of type N.

Template Parameters:

D	dimension of the vector
N	numerical type of the vector elements

Constructor & Destructor Documentation

template<unsigned D, typename N>

VecMath::Vector< D, N >::Vector

(

const N &

x

)

Make all elements have the same size.

Parameters:

x	The number all Vector components are set to.

References VecMath::Vector< D, N >::_x.

template<unsigned D, typename N>

VecMath::Vector< D, N >::Vector	(	N	x0,
		N	x1,
			...
	)

Constructor with variable argument list.

To avoid using variable arglists, for D up to 10 you can use makeVector().

Parameters:

x0	the vector's first element.
x1	the vector's second element.
...	the vector's other elements.

Returns:

dimension of the Vector (the template parameter D)

const

Convert the Vector into an array of arbitrary objects.

Array of floats is needed by glLightfv(). Any other type can be a target type as long as a conversion exists from N to T.

Template Parameters:

T	The type of objects the vector elements are converted to. A cast operator to T objects must exist for type N.

Parameters:

s	scalar type

Returns:

Parameters:

Y	other Vector

Returns:

*this-Y

i

)

const

Returns component i by value.

Parameters:

i	index of the element

Returns:

non-const reference to the accessed element

template<unsigned D, typename N >

N & VecMath::Vector< D, N >::operator[]

(

unsigned

i

)

Returns a reference to component i.

Parameters:

i	index of the element

Returns:

non-const reference to the accessed element
