Detailed Description

Generated from:  MR::PointToPointAligningTransform

This class and its main method can be used to solve the problem well-known as the absolute orientation problem.
It means computing the transformation that aligns two sets of points for which correspondence is known.

findBestRigidScaleXf()

AffineXf3d meshlib.mrmeshpy.PointToPointAligningTransform.findBestRigidScaleXf

(

self

)

this version searches for best rigid body transformation with uniform scaling

findBestRigidXf()

this version searches for best rigid body transformation

findBestRigidXfFixedRotationAxis()

AffineXf3d meshlib.mrmeshpy.PointToPointAligningTransform.findBestRigidXfFixedRotationAxis	(		self,
		Vector3d	axis )

this version searches for best transformation where rotation is allowed only around given axis and with arbitrary translation

findBestRigidXfOrthogonalRotationAxis()

AffineXf3d meshlib.mrmeshpy.PointToPointAligningTransform.findBestRigidXfOrthogonalRotationAxis	(		self,
		Vector3d	ort )

(

self

)

Simplified solution for translational part only

totalWeight()

float meshlib.mrmeshpy.PointToPointAligningTransform.totalWeight

(

self

)

returns summed weight of points accumulated so far
