Welcome to Python-flavored Magnum! Please note that, while already being rather stable, this functionality is still considered experimental and some APIs might get changed without preserving full backwards compatibility.

magnum.math module

Math library

In the C++ API, math types are commonly used via typedefs in the root namespace, only library-level generic code uses things like Math::Vector<size, T>. Since Python doesn’t have templates or generics, there are no generic variants in the magnum.math module, all the concrete types are in the root module with the same names as in the C++ variant.

All math structures are instantiated for the most common sizes and types and so they all share a very similar API. As in C++, main differences are between floating-point types and integral types (one having normalization and projection while the other having bitwise operations) and extra convenience methods added for vectors of particular size.

using namespace Magnum;
Vector4i b{3, 4, 5, 6};
b.b() *= 3;
b.xy() += {1, -1};
Debug{} << b;
// Vector(4, 3, 15, 6)

C++

>>> from magnum import *
>>> b = Vector4i(3, 4, 5, 6)
>>> b.b *= 3
>>> b.xy += (1, -1)
>>> b
Vector(4, 3, 15, 6)

Python

As shown above, all math types are constructible from a (nested) tuple of matching type, matching the convenience of C++11 uniform initializers. As another example, a function accepting a Quaternion will accept a ((x, y, z), w) tuple as well, but not (x, y, z, w), as that is not convertible to a pair of a three-component vector and a scalar.

Magnum math vs Python math

Subject to change

Currently, doing from magnum import math will bring in the Magnum’s math module which at the moment does not contain the well-known Python APIs and constants. In particular, calling magnum.math.sin() expects an explicit Deg / Rad type, while Python’s math.sin() doesn’t. This will get resolved either by making all Python overloads present in the same module or giving the user an option whether to use Magnum math or Python math. For now, to avoid confusion, do for example this:

>>> import math
>>> import magnum.math as mmath
>>> mmath.sin(Deg(45.0))
0.7071067811865475
>>> math.sin(45.0*math.pi/180)
0.7071067811865475

Float vs double overloads

Since Python doesn’t really differentiate between 32bit and 64bit doubles, all scalar functions taking or returning a floating-point type (such as the Deg / Rad types, math.pi or math.sin) use the double variant of the underlying C++ API — the extra arithmetic cost is negligible to the Python-to-C++ function call overhead.

On the other hand, matrix and vector types are exposed in both the float and double variants.

Implicit conversions; NumPy compatibility

All vector classes are implicitly convertible from a tuple of correct size and type as well as from/to type implementing the buffer protocol, and these can be also converted back to lists using list comprehensions. This makes them fully compatible with numpy.ndarray, so the following expressions are completely valid:

>>> Matrix4.translation(np.array([1.5, 0.7, 3.3]))
Matrix(1, 0, 0, 1.5,
       0, 1, 0, 0.7,
       0, 0, 1, 3.3,
       0, 0, 0, 1)

>>> m = Matrix4.scaling((0.5, 0.5, 1.0))
>>> np.array(m.diagonal())
array([0.5, 0.5, 1. , 1. ], dtype=float32)

For matrices it’s a bit more complicated, since Magnum is using column-major layout while numpy defaults to row-major (but can do column-major as well). To ensure proper conversions, the buffer protocol implementation for matrix types handles the layout conversion as well. While the matrix are implicitly convertible from/to types implementing a buffer protocol, they are not implicitly convertible from/to plain tuples like vectors are.

To simplify the implementation, Magnum matrices are convertible only from 32-bit and 64-bit floating-point types ('f' and 'd' numpy dtype). In the other direction, unless overridden using dtype or order, the created numpy array matches Magnum data type and layout:

>>> a = Matrix3(np.array(
...     [[1.0, 2.0, 3.0],
...      [4.0, 5.0, 6.0],
...      [7.0, 8.0, 9.0]]))
>>> a[0] # first column
Vector(1, 4, 7)

>>> b = np.array(Matrix3.rotation(Deg(45.0)))
>>> b.strides[0] # column-major storage
4
>>> b[0] # first column, 32-bit floats
array([ 0.70711, -0.70711,  0.     ], dtype=float32)

>>> c = np.array(Matrix3.rotation(Deg(45.0)), order='C', dtype='d')
>>> c.strides[0] # row-major storage (overridden)
24
>>> c[0] # first column, 64-bit floats (overridden)
array([ 0.7071068, -0.7071068,  0.       ])

Major differences to the C++ API

All vector and matrix classes implement len(), which is used instead of e.g. Math::Vector::Size. Works on both classes and instances.
Math::Matrix3::from() / Math::Matrix4::from() are named Matrix3.from_() / Matrix4.from_() because from is a Python keyword and thus can’t be used as a name.
Math::isInf() and Math::isNan() are named math.isinf() and math.isnan() for consistency with the Python math module

Math::gather() and Math::scatter() operations are implemented as real swizzles:

>>> a = Vector4(1.5, 0.3, -1.0, 1.0)
>>> b = Vector4(7.2, 2.3, 1.1, 0.0)
>>> a.wxy = b.xwz
>>> a
Vector(0, 1.1, -1, 7.2)

mat[a][b] = c on matrices doesn’t do the expected thing, use mat[a, b] = c instead
Math::BitVector::set() doesn’t exist, use [] instead
While both boolean and bitwise operations on Math::BitVector behave the same to ensure consistency in generic code, this is not possible to do in Python. Here the boolean operations behave like if any() was applied before doing the operation.

Static constructors and instance method / property overloads

While not common in Python, the Matrix4.scaling() / Matrix4.rotation() methods mimic the C++ equivalent — calling Matrix4.scaling(vec) will return a scaling matrix, while mat.scaling() returns the 3x3 scaling part of the matrix. With Matrix4.translation, it’s a bit more involved — calling Matrix4.translation(vec) will return a translation matrix, while mat.translation is a read-write property accessing the fourth column of the matrix. Similarly for the Matrix3 class.
