Member Function Documentation

void Transform::AddChangeOfBasis	(	const V3< double > &	x,
		const V3< double > &	y
	)

Adds a change of basis to transform.

Takes two orthonormal vectors as parameters and forms an orthonormal basis. No checks are done.

Parameters:

x	First vector in new basis.
y	Second vector in new basis.

void Transform::AddChangeOfBasis	(	const V3< double > &	x,
		const V3< double > &	y,
		const V3< double > &	z
	)

Adds a change of basis to transform.

Takes three orthonormal vectors as parameters and adds this basis to transform. No checks are done.

Parameters:

x	First vector in new basis.
y	Second vector in new basis.
z	Third vector in new basis.

void Transform::AddScaling	(	double	x,
		double	y,
		double	z
	)

Adds a scaling to transform.

Takes three scaling parameters.

Parameters:

x	Scale factor for x axis.
y	Scale factor for y axis.
z	Scale factor for z axis.

(

const V3< double > &

v

)

const

Performs the inverse transform on a vector.

NB: This only works if the transform is orthonormal.

Parameters:

v	Input vector.

return V3 Transformed vector.

const V3< double > Transform::ApplyTransform

(

const V3< double > &

v

)

const

Performs the transform on a vector.

Parameters:

v	Input vector.

return V3 Transformed vector.
