Detailed Description

template<unsigned D, unsigned D_>
class Projector< D, D_ >

A functor class to project a D -dimensional object to D-1 dimensions.

Template Parameters:

D	Original dimension of the object
D_	Dimension to project onto

Todo:

make scrW and camW vectors for consecutive operations

add possibility to transform before projecting - or make a process separate from projection

template<unsigned D, unsigned D_>

void Projector< D, D_ >::checkConsistency	(	double	scrW,
		double	camW
	)		[inline, private]

Check if a projection makes sense, throw if it doesn't.

Parameters:

scrW	Distance of the "screen" to be projected onto from the origin
camW	Distance of the camera/eye onto from the origin

Referenced by Projector< D, D_ >::operator()().

		double	scrW,
		double	camW
	)		[inline, private]

Perform the projection from dimension D to dimension D-1.

Parameters:

x	The array of vertices to be projected
scrW	Distance of the "screen" to be projected onto from the origin
camW	Distance of the camera/eye onto from the origin

Returns:

x projected one dimension down

		double	scrW,
		double	camW
	)		[inline]

Project an array of vertices of dimension D to dimension D_ < D.

Parameters:

x	The array of vertices to be projected
scrW	Distance of the "screen" to be projected onto from the origin
camW	Distance of the camera/eye onto from the origin

Returns:

x projected to D_

template<unsigned D, unsigned D_>

std::vector<VecMath::Vector<D_> > Projector< D, D_ >::operator()	(	const std::vector< VecMath::Vector< D > > &	x,
		const std::vector< double > &	scrW,
		const std::vector< double > &	camW
	)		[inline]

Project an array of vertices of dimension D to dimension D_ < D.

Parameters:

x	The array of vertices to be projected
scrW	Distances of the "screen" to be projected onto from the origin, one for every projection operation
camW	Distances of the camera/eye onto from the origin, one for every projection operation

Returns:

x projected to D_
