Stanislaw Halik	c1578c0d79	Math: workaround MSVC2022 bug with constexpr conversions and C++20 Upstream bugreport at https://developercommunity.visualstudio.com/t/MSVC-1933-fails-to-compile-valid-code-u/10185268	4 years ago
Vladimír Vondruš	6bdffb2796	Test: make use of CORRADE_SKIP_IF_NO_ASSERT().	4 years ago
Vladimír Vondruš	9874c44262	Don't rely on __GNUC__ being always 4 on Clang. Certain Clang-based IDEs (CLion) "emulate" a compiler by inheriting all its defines, which means one gets __clang__ defined but also __GNUC__ set to 11 or whatever, breaking all these assumptions.	4 years ago

Vladimír Vondruš	5c6b98391d	Math,DebugTools: adapt tests for Android differences in NaN printing. What a waste of energy. I need my own float printing code already.	4 years ago
Vladimír Vondruš	ff1b0ab307	Math: add off-center variants of 2D/3D orthographic projection as well. Was just perspective projection right now.	5 years ago
Vladimír Vondruš	dd3ce93888	Math: MSVC 2015, you ICEd.	5 years ago
Vladimír Vondruš	08a6e7d957	Math: explicit test that all types are trivially copyable. I saw some copy constructors here and there and wasn't sure.	5 years ago
Vladimír Vondruš	7072befbdb	Math: generalize slicing and expanding to arbitrarily-sized matrices. Originally was done only for square matrices, but now I need that for converting 3x3 -> 3x4 and back (UBO packing, ugh ugh), so let's generalize.	5 years ago
Vladimír Vondruš	ed9deff432	Test: adapt to a less shitty CORRADE_COMPARE().	5 years ago
Vladimír Vondruš	3d136503d8	Updated copyright year.	5 years ago
Vladimír Vondruš	e6322dcfd1	Math: use angle literals in all test code. It was originally done using the Deg() / Rad() constructors in order to be compatible with GCC 4.6, but fortunately those days are long gone. Co-authored-by: Squareys <squareys@googlemail.com>	6 years ago
Vladimír Vondruš	ca8172311d	Math: FFS, GCC.	6 years ago
Vladimír Vondruš	12577ce07f	Math: verify normal matrix calculation against the ground truth code. It gives the same result, nevertheless something is not right when it comes to negatively scaled meshes. Postponing the rest of the investigation to later.	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	65a2ced2a7	Make this compile and test cleanly with CORRADE_NO_ASSERT defined.	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
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	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	a1cc0cb62d	Math: off-center Matrix4::perspectiveProjection().	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	3626562e1d	Adapted to Corrade changes. Mostly missing includes now.	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	e75c7639e7	Math: test Matrix[34]::scalingSquared().	7 years ago
Vladimír Vondruš	2149f7b869	Wrap all tests in unnamed namespaces. This makes the compiler warn about test cases that aren't ever used, which is a good thing.	7 years ago

Vladimír Vondruš	3e3eb21181	Math: correct order for test implementations.	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	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	e9a2623e02	Math: expect NoInit test failures on GCC 6.1+ with optimizations enabled. It's nothing harmful, just inefficient.	10 years ago

Vladimír Vondruš	40d60f6a3f	Math: make all constructor noexcept and test their behavior.	10 years ago
Vladimír Vondruš	288a1f265c	Math: this shouldn't have been here. Fixes test failures on all platforms. Ha!	10 years ago
Vladimír Vondruš	c2d2737ca6	Math: test and document Matrix4::*projection() harder.	10 years ago
Vladimír Vondruš	41253de1d5	Math: make Matrix4::transformPoint() work with projection matrices. Dividing by w instead of ignoring it.	10 years ago
Vladimír Vondruš	23646e6690	Hell, this project is big.	10 years ago
Vladimír Vondruš	30fc1411bb	Adapted to Corrade changes.	10 years ago
Vladimír Vondruš	d7e507a2a7	MSVC 2015 compatibility: Math copy/conversion constexpr issues. I don't know why, but marking the output of copy constructor of any subclass or output of conversion operator of any class as constexpr causes MSVC to complain about non-constant expression. Probably just another bug.	11 years ago
Vladimír Vondruš	350d820823	Math: cleanup.	11 years ago
