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	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	e6b7aa12fa	Updated copyright year.	7 years ago
Borislav Stanimirov	f7f2ab8cb5	Math: added StrictWeakOrdering for math types	8 years ago
Vladimír Vondruš	5792d7f06a	Math: fun with printing NaNs :(	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	7df90af144	Math: work around MSVC 2017 15.7.2 ICEs. Reported here: https://developercommunity.visualstudio.com/content/problem/259204/1572-regression-ice-in-constexpr-code-involving-de.html	8 years ago
Vladimír Vondruš	623fa97970	Updated copyright year.	8 years ago
Vladimír Vondruš	7a16273e5d	Updated copyright year.	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	70ef473710	Math: verify that the NoInit constructors are explicit.	10 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	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	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	fbe4330298	Math: cleanup in tests.	11 years ago
Vladimír Vondruš	f30a4677eb	Math: added Matrix[34]::shearing*().	11 years ago
Vladimír Vondruš	c71dc12503	Making test declarations more compact. Yet again I experienced how insanely large this thing got over the years.	11 years ago
Vladimír Vondruš	6488fe6e75	Oh, it's 2015 already.	11 years ago
Vladimír Vondruš	05565ef4f7	Math: document some potentially non-obvious tricks.	12 years ago
Vladimír Vondruš	4a4768a12a	Use template aliases where possible. Because with GCC 4.7 we can.	12 years ago
Vladimír Vondruš	a9a5ead13d	Dropped GCC 4.6 support.	12 years ago
Vladimír Vondruš	6f0ba96cb6	Happy new year too.	12 years ago
Vladimír Vondruš	0616f24f34	Making includes absolute, part 5: absolute includes everywhere. The only places where they aren't absolute are: - when header is included from corresponding source file - when including headers which are not part of final installation (e.g. test-specific configuration, headers from Implementation/)	12 years ago
Vladimír Vondruš	8c2291aa49	Making includes absolute, part 4: using absolute includes for Corrade. Also adapted to some Corrade renames.	12 years ago
Vladimír Vondruš	45a10cefdf	Making includes absolute, part 1: moving files around. Everything what was in src/ is now in src/Corrade, everything from src/Plugins is now in src/MagnumPlugins, everything from external/ is in src/MagnumExternal. Added new CMakeLists.txt file and updated the other ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED is set, everything compiles and installs like previously except for the plugins, which are now in MagnumPlugins and not in Magnum/Plugins.	12 years ago
Vladimír Vondruš	ab651bb61c	Various minor cleanup.	13 years ago
Vladimír Vondruš	f130ce5891	Added convenience Matrix2x2, Matrix3x3 and Matrix4x4 aliases. Unlike Matrix3/Matrix4 these don't have any transformation-related functions. Deprecated the old Matrix2 typedef, which is now replaced with Matrix2x2 and will be removed in future release.	13 years ago
Vladimír Vondruš	f2840e5880	Math: assert uniform scaling in Matrix[34]::rotation(). Needed to adjust the test cases slightly, because they were firing the assert even if they shouldn't and the "expect fail" case wasn't working at all. I now badly need proper floating-point equality comparison.	13 years ago
Vladimír Vondruš	59be5e26f7	Math: added uniform scaling extraction to Matrix[34].	13 years ago
Vladimír Vondruš	bd00adc437	Math: test copy construction from base classes. Copy construction from the same class should just work.	13 years ago
Vladimír Vondruš	7427292173	Math: test "implicitness" of value constructors.	13 years ago
Vladimír Vondruš	20dcab0c88	Math: added Matrix[34]::rotationNormalized(). Useful to pass normal matrices to shader, namely with recent commit `b349ca54ad`.	13 years ago
Vladimír Vondruš	06a4e297bc	Math: deinlined heavy functions, removed redundant `inline`. Also fixed unary RectangularMatrix::operator-() and Vector::operator-() documentation (was stating that the operation is done in-place, which is impossible.	13 years ago
Vladimír Vondruš	a4a962f686	Math: fixed matrix tests (spotted by Clang). Either GCC 4.8 poorly implements C++11 or it already has support for some proposed C++14 feature, which allows to elide successive initializer braces.	13 years ago
Vladimír Vondruš	a21fd0df07	Math: ability to convert matrices from/to external representation.	13 years ago
Vladimír Vondruš	1d5e3fee7a	Math: test that implicit conversion of underlying type can't compile.	13 years ago
Vladimír Vondruš	33058aa5b0	Math: Matrix::invertedOrthogonal(), Matrix{3,4}::invertedRigid(). Renamed original invertedEuclidean() functions to invertedRigid() and simplified them using isRigidTransformation().	13 years ago
Vladimír Vondruš	dfe2571047	Math: added Matrix{3,4}::isRigidTransformation().	13 years ago
Vladimír Vondruš	c5ab86794b	Relicensing to MIT/Expat license, part 3: source files. Added license header also to shader sources. Hopefully it won't harm compilation times too much.	13 years ago
Vladimír Vondruš	231f3277ab	Adapted to Corrade changes. Allowing to instantiate Trade::AbstractImporter subclasses directly without plugin manager.	13 years ago
