Detailed Description

Generated from:  MR::MultiwayAligningTransform

This class can be used to solve the problem of multiple 3D objects alignment,
by first collecting weighted links between pairs of points from different objects,
and then solving for transformations minimizing weighted average of link penalties

Constructor & Destructor Documentation

__init__()

None meshlib.mrmeshpy.MultiwayAligningTransform.__init__	(		self,
		int	numObjs = 0 )

initializes internal data to start registering given number of objects

Member Function Documentation

add() [1/5]

None meshlib.mrmeshpy.MultiwayAligningTransform.add	(		self,
		int	objA,
		Vector3d	pA,
		int	objB,
		Vector3d	pB,
		float	w = 1 )

appends a 3D link into consideration: one point (pA) from (objA), and the other point (pB) from (objB)
with link penalty equal to weight (w) times squared distance between two points

add() [2/5]

None meshlib.mrmeshpy.MultiwayAligningTransform.add	(		self,
		int	objA,
		Vector3d	pA,
		int	objB,
		Vector3d	pB,
		Vector3d	n,
		float	w = 1 )

appends a 1D link into consideration: one point (pA) from (objA), and the other point (pB) from (objB)
with link penalty equal to weight (w) times squared distance between their projections on given direction (n);
for a point on last fixed object, it is equivalent to point-to-plane link with the plane through that fixed point with normal (n)

add() [3/5]

None meshlib.mrmeshpy.MultiwayAligningTransform.add	(		self,
		int	objA,
		Vector3f	pA,
		int	objB,
		Vector3f	pB,
		float	w = 1 )

appends a 3D link into consideration: one point (pA) from (objA), and the other point (pB) from (objB)
with link penalty equal to weight (w) times squared distance between two points

add() [4/5]

None meshlib.mrmeshpy.MultiwayAligningTransform.add	(		self,
		int	objA,
		Vector3f	pA,
		int	objB,
		Vector3f	pB,
		Vector3f	n,
		float	w = 1 )

appends a 1D link into consideration: one point (pA) from (objA), and the other point (pB) from (objB)
with link penalty equal to weight (w) times squared distance between their projections on given direction (n);
for a point on last fixed object, it is equivalent to point-to-plane link with the plane through that fixed point with normal (n)

add() [5/5]

None meshlib.mrmeshpy.MultiwayAligningTransform.add	(		self,
		MultiwayAligningTransform	r )

appends links accumulated in (r) into this

reset()

None meshlib.mrmeshpy.MultiwayAligningTransform.reset	(		self,
		int	numObjs )

reinitializes internal data to start registering given number of objects

solve() [1/2]

std_vector_RigidXf3_double meshlib.mrmeshpy.MultiwayAligningTransform.solve

(

self

)

solve() [2/2]

std_vector_RigidXf3_double meshlib.mrmeshpy.MultiwayAligningTransform.solve	(		self,
		MultiwayAligningTransform.Stabilizer	stab )

finds the solution consisting of all objects transformations (numObj),
that minimizes the summed weighted squared distance among accumulated links;
the transform of the last object is always identity (it is fixed)
