List of all members.

Public Member Functions
	Transform ()
	Construct the identity.
	Transform (const types::quat &rotation, const types::pure &translation=types::pure(), types::real scaling=types::real(1))
	Constructor. See dim3::Transform.
const types::quat &	rotation () const
	Rotation state.
void	rotation (const types::quat &a)
	Rotation state.
const types::pure &	translation () const
	Translation state.
void	translation (const types::pure &a)
	Translation state.
types::real	scaling () const
	Scaling state.
void	scaling (types::real a)
	Scaling state.
void	left_act (const Transform &a)
	*this := a * (*this)
void	right_act (const Transform &a)
	*this := (*this) * a
void	act (const Transform &action, const Transform &basis)
	General differential action.
void	assign (const Transform &a)
	*this := a
void	identity ()
	*this := 1
void	invert ()
	*this := (*this)^(-1)
void	normalize ()
	Snap to closest orthogonal transform. The translation component is retained.
bool	operator== (const Transform &a) const
	Equal by value.
bool	operator!= (const Transform &a) const
	Unequal by value.
Actions
The basis argument is similarity-conjugated: *this := basis*action*(basis)^(-1)*(*this) basis == IDENTITY means left action. basis == *this means right action.
virtual void	rotate (types::real angle, const types::pure &axis, const Transform &basis=IDENTITY)=0
	Rotate around this axis by this angle (in radians). The axis must have unit length.
virtual void	translate (const types::pure &dt, const Transform &basis=IDENTITY)=0
	*this := (*this) + dt
virtual void	scalate (types::real ds, const Transform &basis=IDENTITY)=0
	*this := (*this)*ds
Static Public Attributes
const Transform &	IDENTITY
	The group identity element.
