Detailed Description

Manages a similarity transformation (translation, rotation, uniform scale)

Constructor & Destructor Documentation

Similarity::Similarity ( )

creates an identity transformation

Similarity::Similarity	(	QVector3D	translation,
		QQuaternion	rotation,
		float	scale = `1.0f`
	)

creates a similarity from translation, rotation and scale

Similarity::Similarity ( QMatrix4x4 rigidTransformation)

creates a similarity from a transformation matrix.

Parameters

rigidTransformation must only contain rigid transformations!

Similarity::~Similarity ( void )

Member Function Documentation

Similarity Similarity::bezier	(	QList< Similarity >	controlPoints,
		float	t
	)

static

returns a point on a bezier curve of Similarities, defined by controlPoints and parameter t

QList< Similarity > Similarity::bezierRecursion	(	QList< Similarity >	input,
		float	t
	)

staticprotected

must only be called by bezier(QList<Similarity> controlPoints, float t)

QVector3D Similarity::distance	(	Similarity	a,
		Similarity	b
	)

static

returns a distance measure for two Similarities

Similarity Similarity::interpolate	(	Similarity	a,
		Similarity	b,
		float	t
	)

static

interpolates between two Similarities

Parameters

t	t=0 ==> returns a; t=1 ==> returns b. can be anything.

Similarity Similarity::interpolate	(	Similarity	a,
		Similarity	b,
		float	tTrans,
