Member Function Documentation

__call__()

Vector3d mrmeshpy.AffineXf3d.__call__	(		self,
		Vector3d	x )

application of the transformation to a point

__eq__()

bool mrmeshpy.AffineXf3d.__eq__	(		self,
		AffineXf3d	b )

__mul__()

AffineXf3d mrmeshpy.AffineXf3d.__mul__	(		self,
		AffineXf3d	v )

composition of two transformations:
\\f( y = (u * v) ( x ) = u( v( x ) ) = ( u.A * ( v.A * x + v.b ) + u.b ) = ( u.A * v.A ) * x + ( u.A * v.b + u.b ) \\f)

__ne__()

bool mrmeshpy.AffineXf3d.__ne__	(		self,
		AffineXf3d	b )

__repr__()

str mrmeshpy.AffineXf3d.__repr__

(

self

)

inverse()

AffineXf3d mrmeshpy.AffineXf3d.inverse

(

self

)

computes inverse transformation

linear()

AffineXf3d mrmeshpy.AffineXf3d.linear ( Matrix3d A )

static

creates linear-only transformation (without translation)

linearOnly()

Vector3d mrmeshpy.AffineXf3d.linearOnly	(		self,
		Vector3d	x )

applies only linear part of the transformation to given vector (e.g. to normal) skipping adding shift (b)
for example if this is a rigid transformation, then only rotates input vector

operator() [1/2]

AffineXf3d mrmeshpy.AffineXf3d.operator ( * args, ** kwargs )

static

operator() [2/2]

AffineXf3d mrmeshpy.AffineXf3d.operator ( * args, ** kwargs )

static

translation()

AffineXf3d mrmeshpy.AffineXf3d.translation ( Vector3d b )

static

creates translation-only transformation (with identity linear component)

xfAround()

AffineXf3d mrmeshpy.AffineXf3d.xfAround ( Matrix3d A, Vector3d stable )

static

creates transformation with given linear part with given stable point
