Constructor & Destructor Documentation

__init__() [1/5]

None meshlib.mrmeshpy.Matrix4f.__init__

(

self

)

__init__() [2/5]

None meshlib.mrmeshpy.Matrix4f.__init__	(		self,
		Vector4f	x,
		Vector4f	y,
		Vector4f	z,
		Vector4f	w )

initializes matrix from 4 row-vectors

__init__() [3/5]

None meshlib.mrmeshpy.Matrix4f.__init__	(		self,
		Matrix3f	r,
		Vector3f	t )

construct from rotation matrix and translation vector

__init__() [4/5]

None meshlib.mrmeshpy.Matrix4f.__init__	(		self,
		AffineXf3f	xf )

Currently `AffineXf3<long long>` doesn't seem to compile, so we disable this constructor for `Matrix4<long long>`, because otherwise
mrbind instantiates the entire `AffineXf3<long long>` and chokes on it.

__init__() [5/5]

None meshlib.mrmeshpy.Matrix4f.__init__	(		self,
		Matrix4f	arg0 )

Implicit copy constructor.

Member Function Documentation

__call__() [1/3]

element access

__call__() [2/3]

__call__() [3/3]

Vector3f meshlib.mrmeshpy.Matrix4f.__call__	(		self,
