Squareys	f69f3393ec	Math: Add DualQuaternion/DualComplex::from(rotation, translation) Signed-off-by: Squareys <squareys@googlemail.com>	6 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	c85b537937	Revert "Math: preserve signs in the Matrix[34]::scaling() getter." Turns out this seriously broke properites that should always hold, such as that RS = M for a R and S extracted out of M. Another way to fix this would be flipping signs in the rotation() / rotationShear() / ... queries as well, but that adds extra operations to both rotation() and scaling() and at that point it's just better to do what was done the whole decade before. To ensure this doesn't happen again and doesn't cost me a whole day of debugging in an end-user app (SceneGraph TRS transformations got broken because those assume that rotation() and scaling() do* combine back, which is a reasonable thing to assume), the docs are extended to note this and there's an explicit test for both negative scale and large angle corner cases as well. This reverts commit `9aa68715db`.	6 years ago
Nghia Truong	1ef813fdad	Math: add reflect() and refract() functions. Co-authored-by: Vladimír Vondruš <mosra@centrum.cz>	6 years ago
Vladimír Vondruš	9aa68715db	Math: preserve signs in the Matrix[34]::scaling() getter. This is a breaking change, but I think it is worth doing. Because now Matrix4::scaling(vec).scaling() == vec which was true also for translation and other.	6 years ago

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	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	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
