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
Vladimír Vondruš	6488fe6e75	Oh, it's 2015 already.	11 years ago
Vladimír Vondruš	00124f65eb	Math: return unspecified value after an assertion. The user shouldn't expect anything after assertion anyway and it only adds unnecessary noise to the implementation and tests.	12 years ago
Vladimír Vondruš	11ed4882e0	Removed some workarounds for references in documentation. Fixed in Doxygen master. Yay!	12 years ago
Vladimír Vondruš	7dd224ed21	Math: removed autolink-preventing % noise, removed unneeded HTML tags.	12 years ago
Vladimír Vondruš	664e765fd9	Doc++ Fixed Doxygen warnings, improved some workarounds. Everything now uses explicit references (except where it doesn't work).	12 years ago
Vladimír Vondruš	4a4768a12a	Use template aliases where possible. Because with GCC 4.7 we can.	12 years ago
Vladimír Vondruš	6c9066be8c	doc: removed old Doxygen workarounds. It can finally handle operators, yay! (Well, some of them...)	12 years ago
Vladimír Vondruš	81039fc2c9	Math: completed documentation review.	12 years ago
Vladimír Vondruš	2235cb76b1	Apparently Android is something like newlib.	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	759a28ef45	Math: improved documentation for *::isNormalized().	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	e147cc3992	Doc++, TODO++	13 years ago
Vladimír Vondruš	7ef8432fbe	Doxygen: ignore specific namespaces instead of whole directories. Less maintenance burden with `#ifndef DOXYGEN_GENERATING_OUTPUT`, removed the ones which are not needed anymore.	13 years ago
Vladimír Vondruš	8d5b2cae71	Math: std::hypot() is not available in NaCl newlib. Probably bug / not-yet-implemented feature.	13 years ago
Vladimír Vondruš	ce6f999904	Math: better isNormalized() implementation. Comparing squared length to 1 is not sufficient to compare within range [1 - epsilon, 1 + epsilon], as e.g. Quaternion with dot() = 1 + 1e-7 when converted to matrix has column vectors with dot() = 1 + 1e-6, which is just above 1 + epsilon. Thus it's needed to compare sqrt(dot()) in range [1 - epsilon, 1 + epsilon] or dot() in range [1 - 2epsilon + epsilon^2, 1 + 2epsilon + epsilon^2]. Because epsilon^2 is way off machine precision, it's omitted, thus dot() in all isNormalized() implementations is now compared this way: abs(dot() - 1) < 2*epsilon;	13 years ago
Vladimír Vondruš	3e0e91d7db	Math: renamed {rotationAngle, rotationAxis}() -> {rotation, angle, axis}(). DualQuaternion and DualComplex has now only rotation() which returns full rotation part, rotationAngle() and rotationAxis() on Quaternion and Complex were renamed to angle() and axis().	13 years ago
Vladimír Vondruš	1790f37295	Math: added convenience functions {Complex,DualComplex}::isNormalized().	13 years ago
Vladimír Vondruš	9128820e35	Math: ability to create Complex and DualComplex from matrix.	13 years ago
Vladimír Vondruš	408f40a908	Math: renamed MathTypeTraits to TypeTraits. As there is no Magnum::TypeTraits struct anymore, there is no need to have redundant name in it. Hopefully Doxygen will handle the difference between this and Corrade's TypeTraits.h properly.	13 years ago
Vladimír Vondruš	6a5d75d1e4	Relicensing to MIT/Expat license, part 2: headers.	13 years ago
Vladimír Vondruš	618b556381	Math: crosslinked documentation with missing type aliases.	13 years ago

Vladimír Vondruš	8913e38432	Math: documented this whole transformation thingy.	13 years ago
Vladimír Vondruš	14460cf0f4	Math: renamed *::matrix() to ::toMatrix(). It better visualizes the fact that neither (Dual)Complex nor (Dual)Quaternion contains the matrix inside them, but performs (possibly costly) conversion.	13 years ago
Vladimír Vondruš	268c07acc5	Math: converting DualComplex to matrix.	13 years ago
Vladimír Vondruš	7aac5bd70b	Math: no need for Complex::transformVectorNormalized(). Unlike quaternions it doesn't need inversion or normalization for transforming vectors.	13 years ago

Vladimír Vondruš	143783004b	Math: make Complex::invertedNormalized() consistent with Quaternion.	13 years ago
Vladimír Vondruš	d0fe15737a	Math: mark complex conjugate with asterisk, not overline. Makes it consistent with quaternion conjugate and less confusing for future DualComplex implementation (as dual conjugate is with overline too).	13 years ago
Vladimír Vondruš	c847e1551f	Math: "dot product" of Complex is real number. Brain failure #2. Also I don't know if such thing as dot product exists here :-)	13 years ago

Vladimír Vondruš	728b9a3f2e	Math: construct identity transformation by default. Square matrices already had that, (dual) quaternions too, making that the default also with complex numbers. Updated the documentation to reflect that.	13 years ago
