Description

Affine transformation of three-dimensional coordinates.

Perfoms in-place coordinate transformations.

Coordinates are first multiplied by a matrix, then translated.

Constructor & Destructor Documentation

gmx::AffineTransformation::AffineTransformation	(	Matrix3x3ConstSpan	mat,
		const RVec &	translation
	)

Construct a three-dimensional affine transformation.

Parameters

[in]	mat	to be applied to the vectors
[in]	translation	to be performed on the vectors

Matrix3x3 gmx::AffineTransformation::gradient ( ) const

Return the gradient of this affine transformation.

The gradient of an affine transformation is the transpose of the linear transformation matrix. See, eg, here https://inst.eecs.berkeley.edu/~ee127/sp21/livebook/def_gradient.html

void gmx::AffineTransformation::operator() ( ArrayRef< RVec > vectors ) const

Perform an affine transformation on input vectors.

Parameters

[in,out] vectors to be transformed in-place

void gmx::AffineTransformation::operator() ( RVec * vector ) const

Perform an affine transformation on a vector.

Parameters

[in,out] vector to be transformed in-place
