Vladimír Vondruš	4ebd204482	Math: angle between two complex numbers. Also crosslinked the documentation with similar functions in Vector and Quaternion.	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
Vladimír Vondruš	d2af088880	Math: doc++	13 years ago
Vladimír Vondruš	1d40254676	Math: use Rad for Vector::angle().	13 years ago
Vladimír Vondruš	9cb0b77d1e	Math: added underlying type typedef for remaining types. Also updated and unified documentation.	13 years ago
Vladimír Vondruš	389e9194e0	Math: doc++	13 years ago
Vladimír Vondruš	5673cf2656	Math: better documentation for vector/quat constructors.	13 years ago
Vladimír Vondruš	0144c38a54	Math: moved lerp() from Vector to Functions.h. It does nothing special for vectors (unlike e.g. quaternion LERP) and scalar overload is useful too.	13 years ago
Vladimír Vondruš	ce2a07a09a	Math: slightly faster Vector::projectedOntoNormalized(). The assertion will still compute the dot product (but not in release builds).	13 years ago
Vladimír Vondruš	0885320603	Math: vector dot product in terms of component-wise multiply and sum. Less SIMD alternatives to implement in the future.	13 years ago
Vladimír Vondruš	f517a000ed	Math: follow Vector changes in BoolVector. Added constexpr "filling" constructor, updated tests, added constexpr test.	13 years ago
Vladimír Vondruš	bbc98746e4	Math: properly testing all constexpr methods in Vector. Fixed conversion constructor, as pointer chasings are not allowed in constexpr functions.	13 years ago
Vladimír Vondruš	0f938003df	Math: constexpr implementation for "filling" Vector constructor. Also removed constexpr alternatives to it in Vector2, Vector3 and Vector4 as they are now not needed.	13 years ago
Vladimír Vondruš	a39fa198c8	Math: removed inappropriate `constexpr` from operator!=() Method calling another method that will possibly be done via SIMD in the future cannot be constexpr.	13 years ago
Vladimír Vondruš	f7a8641081	Math: fixed one-argument Vector constructors. It is now possible to implicitly create one-element Vector and also explicitly fill more-element Vector with one value without any ambiguous overload conflicts: Vector<1, int> a1 = 1; // calls implicit constructor //Vector<3, int> a3 = 1; // error! Vector<1, int> b1(1); // still calls the implicit constructor, the // explicit is disabled for one-element vector Vector<3, int> b3(1); // calls the explicit "filling" constructor, // the implicit is disabled for only one argument The downside of this is that now specifying improper element count in constructor doesn't lead to static_assert with human readable error, but rather cryptic "no match" error.	13 years ago
Vladimír Vondruš	60f86b8ea0	Math: added Vector::{min,max}Abs().	13 years ago
Vladimír Vondruš	5b3e1a0ea0	Math: save one unneeded initialization in Vector::sum().	13 years ago
Vladimír Vondruš	799bc629eb	Math: matrix/vector rework, part 4: using BoolVector for comparisons. The comparisons have also SIMD instructions returning bool vector, this future-proofs them. Also it isn't confusing anymore (a < b is true when all are less or just one?).	13 years ago
Vladimír Vondruš	9bbc656da5	Math: creating Vector from one value is broken. Added "expect fail" test, it is not the priority now (and it is handled correctly in subclasses).	13 years ago
Vladimír Vondruš	5819dd4bd7	Math: matrix/vector rework, part 3: conversion as explicit constructor. Also updated all dependent classes to follow the change, such as Color and Rectangle. Backwards compatibility for GCC 4.6 (with lack of support for delegating constructors) will be done as non-constexpr constructor using operator=().	13 years ago
Vladimír Vondruš	baeadc9663	Math: matrix/vector rework, part 2: matrix as array of column vectors. Overall architecture is simplififed with this change and also it's not needed to use reinterpret_cast in matrix internals anymore, thus there is no need for operator() and [][] works now always as expected without any risk of GCC misoptimizations. On the other side, constructing matrix from list of elements is not possible anymore. You have to specify the elements as list of column vectors, which might be less convenient to write, but it helps to distinguish what is column and what is row: Matrix<2, int> a(1, 2, // before 3, 4); Matrix<2, int> a(Vector<2, int>(1, 2), // now Vector<2, int>(3, 4)); For some matrix specializations (i.e. Matrix3 and Matrix4) it is possible to use list-initialization instead of explicit type specification: Matrix<3, int>({1, 2, 3}, {4, 5, 6}, {7, 8, 9}); I didn't yet figure out how to properly implement the general (constexpr) constructor to also take lists, so it's a bit ugly for now. Matrix operations are now done column-wise, which should help with future SIMD implementations, documentation is also updated accordingly. I also removed forgotten remains of matrix/matrix operator*=(), which can be confusing, as the multiplication is not commutative. Why it is not present is explained in `d9c900f076`.	13 years ago
Vladimír Vondruš	4c16a767db	Math: doc++, minor code cleanup.	13 years ago
Vladimír Vondruš	b7b955289a	Math: Vector::lerp() can take `t` of arbitrary type. Usable when interpolating e.g. colors in denormalized integral form, as `t` could be only `0` or `1` in that case, which is pretty unusable.	13 years ago
Vladimír Vondruš	861e16e1f9	Doc++, @todo+-	13 years ago
Vladimír Vondruš	d175dd1054	Updated workarounds for Doxygen 1.8.2. Removed workarounds for alias templates, variadic templates and anonymous enums, but 1.8.2 has some bug with forward declarations causing classes to appear in default namespace, breaking cross-references.	13 years ago
Vladimír Vondruš	03789a5b4b	Math: got rid of MathTypeTraits::NumericType. Was workaround for printing chars with Corrade::Utility::Debug as integers, not needed anymore.	14 years ago
Vladimír Vondruš	a4da7b764a	Adapted to Corrade changes.	14 years ago

Vladimír Vondruš	538601fc06	Minor code cleanup.	14 years ago
Vladimír Vondruš	23a94b2709	Math: Quaternion has dot product too! Original lengthSquared() renamed to parameterless dot(), it is now consistent with what Vector has. Also updated related Vector documentation.	14 years ago
Vladimír Vondruš	d9c900f076	Doc++ * Added math equations to Quaternion, Vector and Matrix method documentation. * Removed confusing Quat=Quat operator overload, as it isn't exactly clear from which side the non-commutative multiplication is done: Quaternion a; a = b; // eh? a = ab; // okay! For similar reason this operator wasn't present in RectangularMatrix either. Unified documentation of expected vector/quaternion normalization state. Now it is not "assumed" but "expected", because failing to do so results in assertion failure.	14 years ago
Vladimír Vondruš	f9f848d94c	Math: ability to multiply and divide Vector with other of arbitrary type.	14 years ago
Vladimír Vondruš	7905a5e96c	Math: return proper type from Vector::projected() in subclasses.	14 years ago
Vladimír Vondruš	5de5b34c48	Math: function for projecting vector onto another.	14 years ago
Vladimír Vondruš	7e66a09461	Marking all constructors explicit, except for matrix and vector classes. It prevents unwanted implicit conversions from e.g. nullptr to Camera, Vector2 to Physics::Point etc. By making all the constructors explicit it is easier to routinely add the keyword to all new classes instead of thinking about cases when to add and when not to.	14 years ago
Vladimír Vondruš	ae013effff	Adapted to Corrade changes. Optimalizations in Corrade::TestSuite and Corrade::Utility::Debug leaded to significant reduction of compilation time - on my machine it was ~5:38 before with building of unit tests enabled, now only ~5:00.	14 years ago
Vladimír Vondruš	6dbdf58476	Component-wise comparison for Vector class.	14 years ago
Vladimír Vondruš	8e3e3ac6d3	Doc++	14 years ago
Vladimír Vondruš	1e2720eeb7	Explicit template instantiation for common matrix and vector functions. Common types used in OpenGL have now explicit template instantiation for debug operators and configuration value parsers/readers.	14 years ago
Vladimír Vondruš	9d9517c824	Vector::angle(): reflect normalization requirement in parameter names. Will be more intuitive when IDE autocompletion kicks in.	14 years ago
Vladimír Vondruš	350fb3a64c	Fixed documentation of Vector::angle().	14 years ago
Vladimír Vondruš	f28f5398d3	Added some @todos .	14 years ago
Vladimír Vondruš	0145343d59	Pedantic: using std::size_t instead of size_t from C compat headers.	14 years ago
Vladimír Vondruš	4aec678539	Have first letter of static constants uppercase, like previously. Lowecase didn't prove to be better, because Doxygen cannot implicitly link to it and it collides with non-type template parameters and private variables.	14 years ago
Vladimír Vondruš	d65b2386b2	Code cleanup.	14 years ago
Vladimír Vondruš	16382c9ba9	No need to have separate ConfigurationValue implementation for Vector.	14 years ago
Vladimír Vondruš	624f4f8531	Inlined inline functions.	14 years ago
Vladimír Vondruš	a385441c02	Moved type conversion constructor from Vector to RectangularMatrix.	14 years ago
Vladimír Vondruš	5d639095ee	Removed "wontfix" TODOs. Loop unrolling is better to leave up to the compiler, as it will do it automatically and it doesn't add any maintenance burden. Constexpr addition, multiplication etc. of Vector would be nice, but will that be really useful? Maybe once if at all?	14 years ago
