Detailed Description

template<class T, int d>
class mathfu::VectorPacked< T, d >

Packed N-dimensional vector.

Some Vector classes are padded so that it's possible to use the data structures with SIMD instructions. This structure can be used in conjunction with unpacked Vector classes to pack data into flat arrays suitable for sending to a GPU (e.g vertex buffers).

For example, to pack (store) an unpacked to packed vector:

VectorPacked<float, 3> packed;
Vector<float, 3> vector(3, 2, 1);
vector.Pack(&packed);

or

Vector<float, 3> vector(3, 2, 1);
VectorPacked<float, 3> packed = vector;

To initialize a vector from a packed vector:

VectorPacked<float, 3> packed = { 3, 2, 1 };
Vector<float, 3> vector(packed);

Template Parameters

T	type of VectorPacked elements.
d	dimensions (number of elements) in the VectorPacked structure.

Public Member Functions
	VectorPacked ()
	Create an uninitialized VectorPacked.
	VectorPacked (const Vector< T, d > &vector)
VectorPacked &	operator= (const Vector< T, d > &vector)

Public Attributes
T	data [d]
	Elements of the packed vector one per dimension.

template<class T, int d>

mathfu::VectorPacked< T, d >::VectorPacked ( const Vector< T, d > &  vector )

inlineexplicit

Create a VectorPacked from a Vector.

Both VectorPacked and Vector must have the same number of dimensions.

Parameters

vector

Vector to create the VectorPacked from.

Member Function Documentation

template<class T, int d>

VectorPacked& mathfu::VectorPacked< T, d >::operator= ( const Vector< T, d > &  vector )

inline

Copy a Vector to a VectorPacked.

Both VectorPacked and Vector must have the same number of dimensions.

Parameters

vector

Vector to copy to the VectorPacked.

Returns

A reference to this VectorPacked.
