arbitrary 4x4 matrix

Constructor & Destructor Documentation

__init__() [1/6]

None mrmeshpy.Matrix4f.__init__ ( * args, ** kwargs )

static

__init__() [2/6]

None mrmeshpy.Matrix4f.__init__

(

self

)

__init__() [3/6]

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

initializes matrix from 4 row-vectors

__init__() [4/6]

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

construct from rotation matrix and translation vector

__init__() [5/6]

None 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__() [6/6]

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

Implicit copy constructor.

Member Function Documentation

__add__()

Matrix4f mrmeshpy.Matrix4f.__add__	(		self,
		Matrix4f	b )

NOTE: We use `std::declval()` in the operators below because libclang 18 in our binding generator is bugged and chokes on decltyping `a.x` and such. TODO fix this when we update libclang.

__call__() [1/3]

float mrmeshpy.Matrix4f.__call__	(		self,
		int	row,
		int	col )

element access

__call__() [2/3]

float mrmeshpy.Matrix4f.__call__	(		self,

__call__() [3/3]

Vector3f mrmeshpy.Matrix4f.__call__	(		self,
		Vector3f	b )

converts 3d-vector b in 4d-vector (b,1), multiplies matrix on it,
and assuming the result is in homogeneous coordinates returns it as 3d-vector

__eq__()

bool mrmeshpy.Matrix4f.__eq__	(		self,
