Member Function Documentation

__call__()

Vector3f meshlib.mrmeshpy.AffineXf3f.__call__	(		self,
		Vector3f	x )

application of the transformation to a point

__eq__()

bool meshlib.mrmeshpy.AffineXf3f.__eq__	(		self,
		AffineXf3f	b )

__mul__()

AffineXf3f meshlib.mrmeshpy.AffineXf3f.__mul__	(		self,
		AffineXf3f	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 meshlib.mrmeshpy.AffineXf3f.__ne__	(		self,
		AffineXf3f	b )

inverse()

AffineXf3f meshlib.mrmeshpy.AffineXf3f.inverse

(

self

)

computes inverse transformation

linear()

AffineXf3f meshlib.mrmeshpy.AffineXf3f.linear ( Matrix3f A )

static

creates linear-only transformation (without translation)

linearOnly()

Vector3f meshlib.mrmeshpy.AffineXf3f.linearOnly	(		self,
		Vector3f	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

translation()

AffineXf3f meshlib.mrmeshpy.AffineXf3f.translation ( Vector3f b )

static

creates translation-only transformation (with identity linear component)

xfAround()

AffineXf3f meshlib.mrmeshpy.AffineXf3f.xfAround ( Matrix3f A, Vector3f stable )

static

creates transformation with given linear part with given stable point
