Detailed Description

Transformation description (API).

Introduction

Transformation objects are a combination of a translation and an orientation defined by the new enumeration Transformation::Orientation whose different values are described in table below. The orientation is done before the translation, which is to say that the orientation is applied in the coordinate system of the model.

The transformation formula is given by:

$\‍[ \Large \left \{ \begin{array}{r c l l l l l} x' & = & (a \times x) & + & (b \times y) & + & tx \\ y' & = & (c \times x) & + & (d \times y) & + & ty \end{array} \right . \‍]$

where x and y are the coordinates of any point, x' and y' the coordinates of the transformed point, tx and ty the horizontal and vertical components of the translation and where a, b, c and d are the coefficients of the matrix associated to the orientation. See Orientation for the value of a, b, c & d.

Remarks: Rotations are done counter clock wise

Constructor & Destructor Documentation

◆ Transformation() [1/4]

Hurricane::Transformation::Transformation ( )

Default constructor : The translation is null and the orientation is equal to ID.

Referenced by applyOn(), getInvert(), getTransformation(), invert(), operator!=(), operator=(), operator==(), and Transformation().

◆ Transformation() [2/4]

Hurricane::Transformation::Transformation	(	const DbU::Unit &	tx,
		const DbU::Unit &	ty,
		const Orientation &	orientation = Orientation::ID )

Builds a transformation whose translation part is defined by the arguments <xt> and <ty> and whose orientation is defined by <orientation> (<ID> by default).

◆ Transformation() [3/4]

Hurricane::Transformation::Transformation	(	const Point &	translation,
		const Orientation &	orientation = Orientation::ID )

Builds a transformation whose translation part is defined by the argument <translation> and whose default orientation is ID.

Builds a transformation whose translation part is defined by the argument <translation> and whose orientation is defined by <orientation>.
