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	1967179a40	Math: slight improvement of Gram-Schmidt orthonormalization algorithm. Using Vector::projectOntoNormalized(), as it is slightly faster, renamed the functions to properly mention that this is orthonormalization.	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	11544813a2	Math: don't needlessly include Matrix in GaussJordanTest. Should save another bit of recompilation time in addition to previous commit.	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	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	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	2d0aad34b2	Math: SVD algorithm implementation.	13 years ago
Vladimír Vondruš	0f547d7e8e	Math: added RectangularMatrix::sum(),product(),{min,max}(),{min,max}Abs().	13 years ago

Vladimír Vondruš	ac9dca0781	Math: access RectangularMatrix's own data directly.	13 years ago
Vladimír Vondruš	08312ae335	Math: minor code reorganization. Place "alias" methods after "implementation" methods.	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	e24207f620	Doc++	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	4c16a767db	Math: doc++, minor code cleanup.	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	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
