Vladimír Vondruš	7c81755152	Math: slightly reorganize Quaternion test.	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	8a63939134	Math: added vector/scalar abs() function.	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	bbea562a6c	Math: properly testing all constexpr methods in RectangularMatrix. Fixed data() method, it doesn't need to use reinterpret_cast.	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	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	0f547d7e8e	Math: added RectangularMatrix::sum(),product(),{min,max}(),{min,max}Abs().	13 years ago
Vladimír Vondruš	60f86b8ea0	Math: added Vector::{min,max}Abs().	13 years ago
Vladimír Vondruš	7b507d0485	Math: improve Vector::min()/max() tests.	13 years ago
Vladimír Vondruš	e58962dc43	Don't use fully qualified Corrade::Utility::Debug when not needed.	13 years ago
Vladimír Vondruš	37955c468f	Math: creating matrix from diagonal, retrieving values on diagonal.	13 years ago
Vladimír Vondruš	0274ad7d56	Math: explicit one-parameter PointD constructor. Was causing improper implicit conversions, such as here (example directly from unit tests, where it was unintentionally used): Vector3 normal; Matrix4 transformation; auto transformedNormal = transformationnormal; Not only that it was possible to multiply 4x4 matrix with 3-component vector, but the resulting type was Point3D which was absolutely confusing. Currently it must be explicitly converted: transformedNormal = transformation*Point3D(normal);	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	dcb4595e6e	Math: new class BoolVector. Will handle output from various comparison operators in Vector.	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	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	263d8351b6	Math: vector overloads for normalize() and denormalize().	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	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	7dc0fc4a4c	Math: Renamed Math.h to Functions.h Math.h is reserved for forward declaration header.	14 years ago
Vladimír Vondruš	7d0a523618	Moved projection matrix computation to Math namespace.	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	f06b53724c	Math: spherical linear Quaternion interpolation.	14 years ago
Vladimír Vondruš	b9f21d1430	Removed unnecessary prefix from test filename. My brain is lagging behind my keyboard.	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	3b57d530a4	Math: test also properties of normalized Quaternion.	14 years ago
Vladimír Vondruš	fcb8a7b768	Got rid of header files in tests. They have no practical use and they only bloat codebase size and add maintenance burden.	14 years ago
Vladimír Vondruš	89c2bf913c	Math: initial implementation of Quaternion class. Still practically unusable.	14 years ago
Vladimír Vondruš	5de5b34c48	Math: function for projecting vector onto another.	14 years ago
Vladimír Vondruš	d981090e86	Functions for inverting Euclidean transformation matrices.	14 years ago
Vladimír Vondruš	e9e0de70d7	Implemented reflection matrices. Long-standing TODO, can be used for in-game mirrors etc. I give up with shearing, as I think that it makes sense only in 2D and I can't find any reasonable use case for that yet.	14 years ago
Vladimír Vondruš	6ae94bffd7	Ability to construct Matrix from rotation/scaling and translation parts.	14 years ago
Vladimír Vondruš	ef779e50b2	Split out lightweight base of swizzle() function to Math namespace. Will make use of SIMD instructions and can be used elsewhere in Math.	14 years ago
Vladimír Vondruš	47c0a7456c	Adapted to Corrade changes. Removing of another <*stream> #include leads to more compilation time saving, now from ~5:12 to ~4:55. Another compilation time improvements will now be possible only by using Clang's modules, I don't know where to optimize further (except for getting rid of <sstream> in tests).	14 years ago
Vladimír Vondruš	0f889369f4	No `using namespace std` anywhere. Also added missing std:: prefix to remaining cases of std::size_t, std::[u]int[0-9]+_t, std::sin() etc., std::exit().	14 years ago
