Vladimír Vondruš	e5844b23b7	Math: use a more common integer rounding calculation in BitVector. The (size - 1)/8 + 1 expression is the same as (size - 1)/8 + 8/8 which is the same as the following in all cases except when size == 0, for which it underflows: (size - 1 + 8)/8 == (size + 7)/8 To avoid needless surprises, I'm changing to what's used everywhere else, including the BitArray, and also reusing the already-calculated value for the _data array size.	3 years ago

Vladimír Vondruš	5312a016f4	Math: rename BoolVector to BitVector. Because it somewhat confusingly may have implied that it's really composed of 8-bit bools, and not bits. The same reasoning was used to pick the name for Corrade's Containers::BitArray. Backwards compatibility aliases are in place as usual, however the internal BoolVectorConverter is now BitVectorConverter and there unfortunately cannot be any backwards compatibility. This breaks only GLM and Eigen integration in the magnum-integration repo, which I'm fixing immediately. I don't expect any user code to use this internal helper. For regular vectors maybe, for this one definitely not.	4 years ago
Vladimír Vondruš	d474f9d176	Math: return an array reference instead of a pointer from data(). This makes it possible to conveniently do things like Containers::StridedArrayView1D<Float> array = …; Vector4 vector{NoInit}; Utility::copy(array, vector); // or the other way around which is especially useful together with the new JSON classes. In some cases this means the function is no longer constexpr, but those weren't constexpr because it was useful for anything, they were only because it was possible. So this breakage shouldn't do any harm I think.	4 years ago

Vladimír Vondruš	3cf4573c0e	Math: drop explicitly defaulted copy constructors. These shouldn't be needed (the newer classes such as Half or CubicHermite don't have them and work fine), moreover Clang 12 is now emitting the following warning for them: Definition of implicit copy assignment operator for 'Foo' is deprecated because it has a user-declared copy constructor [-Wdeprecated-copy]	5 years ago

Vladimír Vondruš	5a1f43f20b	Switch to the new & optimized GenerateSequence from Corrade. This should help slightly with compiler memory usage, on GCC 10 the huge Trade::MaterialData test used "only" 309 instead of 318 MB after this change.	5 years ago
Vladimír Vondruš	1026aee80e	Moved the NoInit tag from Math to the root namespace. The old one is deprecated, and will be removed in a future release. Unfortunately, to avoid deprecation warnings, all use of NoInit in the Math library temporarily have to be Magnum::NoInit This will be cleaned up when the deprecated alias is removed.	6 years ago

Vladimír Vondruš	a920722839	doc: label deprecated APIs and stuff new since 2019.10 with version info. Should make new things more discoverable, avoid confusion when a documented API isn't there and reduce the need for maintaining multiple separate versions of the docs.	7 years ago
Vladimír Vondruš	4b4b8efc1b	Math: doc++ Fixing Engrish while doing the Python bindings.	7 years ago
Vladimír Vondruš	442d5576d0	Math: change the way BoolVector is printed to Debug. Found while working on the Python bindings --- BoolVector4(0b1010) got printed as BoolVector(0101), which is totally confusing. Now it prints it in a way that looks exactly the same as when constructing the vector with binary literals.	7 years ago
Vladimír Vondruš	988a33c000	Added convenience BoolVector2, BoolVector3 and BoolVector4 typedefs.	7 years ago
Vladimír Vondruš	36ba5f4333	Math: ensure ZeroInit and IdentityInit constructors are explicit. Like NoInit ones. Not sure what I was doing there.	7 years ago

Vladimír Vondruš	6e8c16c960	MSVC 2015 Update 1: fixed nearly all constexpr bugs.	11 years ago

Vladimír Vondruš	8984904693	MSVC 2015 compatibility: single value Math constructor constexpr issues. Some could be worked around, but the rest is prevented by inability to delegate constexpr constructors.	11 years ago
Vladimír Vondruš	1d9e6210d8	Use anonymous typed enum instead of static const member variable. The reason behind this is that it's not possible to take address of the enum value -- the generated code can be simpler and no symbol is exported.	11 years ago
Vladimír Vondruš	d0baab2bfe	I hate GCC. Why the hell it does not have std::is_trivially_constructible until version 5?!	11 years ago
Vladimír Vondruš	1b0da5b2df	Math: ability to construct all types without initializing the contents. Useful for squeezing out last bits of performance, e.g. in this case: Vector3 a; a[0] = something++; a[1] = something++; a[2] = something++; In the code all elements are first zeroed out and then overwritten later, thus it might be good to avoid the zero-initialization: Vector3 a{Math::NoInit}; a[0] = something++; a[1] = something++; a[2] = something++; This will of course be more useful in far larger data types and arrays of these.	11 years ago
Vladimír Vondruš	3a8ac02909	Math: more explicit default zero/identity constructors. Some classes are by default constructed zero-filled while other are set to identity and the only way to to check this is to look into the documentation. This changes the default constructor of all classes to take an optional "tag" which acts as documentation about how the type is constructed. Note that this result in no behavioral changes, just ability to be more explicit when writing the code. Example: // These two are equivalent Quaternion q1; Quaternion q2{Math::IdentityInit}; // These two are equivalent Vector4 vec1; Vector4 vec2{Math::ZeroInit}; Matrix4 a{Math::IdentityInit, 2}; // 2 on diagonal Matrix4 b{Math::ZeroInit}; // all zero This functionality was already present in some ugly form in Matrix, Matrix3 and Matrix4 classes. It was long and ugly to write, so it is now generalized into the new Math::IdentityInit and Math::ZeroInit tags, the original Matrix::IdentityType, Matrix::Identity, Matrix::ZeroType and Matrix::Zero are deprecated and will be removed in the future release. Math::Matrix<7, Int> m{Math::Matrix<7, Int>::Identity}; // before Math::Matrix<7, Int> m{Math::IdentityInit}; // now	11 years ago
