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	0ed0f261b4	Math: matrix/vector rework, part 1: synchronized unit tests. They now test the same functionality in two places, but the functionality will be implemented differently for matrix and vector.	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	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	4d6d3fde88	Math: scalar/vector implementation of min(), max() and clamp(). This is gonna be some ugly template hell.	13 years ago

Vladimír Vondruš	bdba6b7221	Math: no need to have two versions of denormalize(), they are the same. Overlooked in `cade175304`.	13 years ago
Vladimír Vondruš	3daefd70a9	Math: simplified internal pow<n>() implementation.	14 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	5ca096512e	Forward declaration header for Math namespace.	14 years ago
Vladimír Vondruš	cade175304	Math: finally implemented precise signed/unsigned normalization. (De)normalization from/to [0, 1] for unsigned types and from/to [-1, 1] for signed types. -1.0 is always denormalized to min+1. Also updated some tests for Color, as they depended on previous imprecise implementation.	14 years ago

Vladimír Vondruš	52300cf402	Math: function for base-2 logarithm. Verbatim copy from Corrade, might be better to have it here too (possibly some SIMD optimizations?).	14 years ago

Vladimír Vondruš	53a95b6296	Math: test also parameterless Quaternion::dot(). Just to be sure (and to be consistent with Vector test).	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	eeed955154	Minor code cleanup.	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
