arbitrary 3x3 matrix

Constructor & Destructor Documentation

__init__()

mrmeshpy.ConstMatrix3f.__init__	(		self,
		*	args,
		**	kwargs )

__init__(*args, **kwargs)
Overloaded function.

1. __init__(self: meshlib.mrmeshpy.ConstMatrix3f, arg0: meshlib.mrmeshpy.ConstQuaternionf) -> None

converts this into 3x3 rotation matrix

2. __init__(self: meshlib.mrmeshpy.ConstMatrix3f) -> None

3. __init__(self: meshlib.mrmeshpy.ConstMatrix3f, x: meshlib.mrmeshpy.ConstVector3f, y: meshlib.mrmeshpy.ConstVector3f, z: meshlib.mrmeshpy.ConstVector3f) -> None

initializes matrix from its 3 rows

4. __init__(self: meshlib.mrmeshpy.ConstMatrix3f, m: meshlib.mrmeshpy.ConstMatrix3d) -> None

Here `T == U` doesn't seem to cause any issues in the C++ code, but we're still disabling it because it somehow gets emitted
  when generating the bindings, and results in duplicate functions in C#.

5. __init__(self: meshlib.mrmeshpy.ConstMatrix3f, arg0: meshlib.mrmeshpy.Matrix3f) -> None

Implicit copy constructor.

6. __init__(self: meshlib.mrmeshpy.ConstMatrix3f, : meshlib.mrmeshpy.Matrix3f) -> None

Member Function Documentation

__add__()

Matrix3f mrmeshpy.ConstMatrix3f.__add__	(		self,
		ConstMatrix3f	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.
