Vladimír Vondruš	0b7831c1ad	doc: pile on more Doxygen workarounds. Sad! https://github.com/doxygen/doxygen/issues/7472	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	515637c76a	Math: implement a robust and faster Matrix4::normalMatrix(). This change makes the operations split into a bunch of separate functions, making the parts easier to document, however with a slight negative effect on debug performance: Starting Magnum::Math::Test::MatrixBenchmark with 16 test cases...

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	64bc7f9c8e	Math: moved configuration value parsers to a dedicated header. There's a lot of string operations and that's nothing good to have included everywhere. Should speed up the compilation quite a bit.	7 years ago
Vladimír Vondruš	e6b7aa12fa	Updated copyright year.	7 years ago
Vladimír Vondruš	f5e30bb5d3	Math: minor coding style cleanup.	8 years ago
Borislav Stanimirov	f7f2ab8cb5	Math: added StrictWeakOrdering for math types	8 years ago
Vladimír Vondruš	0cf65741ae	Math: helpfully print the offending values in all assertions.	8 years ago
Vladimír Vondruš	8d5454b8ff	Math: ability to slice or expand square matrices.	8 years ago
Vladimír Vondruš	4b7dab10e1	Math: improve docs of Matrix4::perspectiveProjection().	8 years ago
Vladimír Vondruš	fbd3dedeb3	Math: add Matrix[34]::rotationShear(), scalingSquared() and scaling(). Important: the rotation() accessor now allows non-uniform scaling but expects orthogonality (previously it allowed non-orthogonal rotation axes but disallowed non-uniform scaling). Documentation of all these accessors is further improved now as well.	8 years ago

Vladimír Vondruš	025ef780b2	Workaround for that one damn Doxygen bug.	9 years ago
Vladimír Vondruš	aa69bbcc19	Math: ability to create matrices with one value for all components. In order to do that with the previous API, one had to write an abomination like auto a = Matrix4x4::fromVector(Math::Vector<16, Float>{0.5f}); Ugh.	9 years ago
Vladimír Vondruš	6e10b2e205	Math: doc++ The TODOs were removed and put into GitHub projects to be a bit more visible to random strangers.	9 years ago
Vladimír Vondruš	28c31bfc96	Math: I don't see why we should have those overloads. The compiler does that for us. Probably a brain fart from 2010. On the other hand, the ConfigurationValue specializations need to be there, because the type is used explicitly as template parameter.	10 years ago

Vladimír Vondruš	b2604bb903	MSVC 2015 compatibility: issues with delegating constexpr tag constructors. Fixed-size constructors were worked around, the rest is now impossible to have constexpr.	11 years ago
Vladimír Vondruš	371adc63f9	MSVC 2015 compatibility: the issues with {} are eternal. Aargh.	11 years ago
Vladimír Vondruš	c4bf8d6eda	Doxygen workarounds. I LOVE this, do you hear me? Especially at 2:40 AM.	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
Vladimír Vondruš	64bc2393d1	Math: made dot(), angle(), *lerp() and cross() free functions. It is often annoying to write e.g. this, especially in generic code: T dot = Math::Vector<size, T>::dot(a, b); When this is more than enough and the compiler can infer the rest from the context: T dot = Math::dot(a, b); There are more downsides and confusing cases (you can call Math::Vector<3, T>::dot(), Math::Vector3<T>::dot() and Color3::dot() and it is still the same function), so I made these as free functions in Math namespace. You can now also abuse ADL for the calls, but I would advise against that for better readability: T d = dot(a, b); // dot?! what on earth is dot? and what is a? The only downside found when porting is that you need to specify the type somehow when having both parameters as initializer lists: T d = dot({2.0f, -1.5f}, {1.0f, 2.5f}); // error T d = dot(Complex{2.0f, -1.5f}, {1.0f, 2.5f}); // okay But that's probably reasonable (and it's also highly corner case, the functions were used this way only in tests). The original static member functions are of course still present, but marked as deprecated and will be removed at some point in future.	11 years ago
