Vladimír Vondruš	54af4015f2	Allow to specify value on diagonal in identity matrix constructor.	14 years ago
Vladimír Vondruš	4f1c7ccfa0	Better (hopefully) way to distinguish between Matrix constructors. Before it was one constructor using bool parameter, which is massive antipattern: Matrix4 m(false); // Huh? No Matrix4 then or what? Iẗ́'s now separated into two distinct constructors, of them one can be already declared as constexpr (hooray). The usage is as follows: Matrix4 a; // Default (identity matrix) Matrix4 b(Matrix4::Identity); // Explicitly identity matrix Matrix4 c(Matrix4::Zero); // Zero-filled matrix Also deleted constructor from one parameter, so following mistakes now cannot compile: Matrix4 d(true); // Both would set element at [0][0] to 1, Matrix4 e(Matrix3::Zero); // and other to 0	14 years ago
Vladimír Vondruš	a23661a171	Doc++ Missed some leftover && from `7e1a260286`, documented Matrix Implementation::SequenceGenerator a bit, added constexpr todos.	14 years ago
Vladimír Vondruš	5293429f31	Ability to construct Matrix from column vectors.	14 years ago
Vladimír Vondruš	e8c76b7d96	Forced exclusive use of bracket operators in Matrix and Vector. Removed functions at(), set() and add(), everything (and more) can be now done using operator[]. Accessing matrix elements is now done through column vectors, e.g.: Matrix4 a; a.at(row, col); // before a[col][row]; // now Note that because operator[] on Matrix returns column vector (there is nothing like row vector), the parameter "order" is now swapped.	14 years ago
Vladimír Vondruš	7e1a260286	Removed && and std::forward from Matrix and Vector constructors. Types saved inside Matrix and Vector will be at most time smaller than or the same size as references to them, so no move semantic and forwarding is necessary.	14 years ago
Vladimír Vondruš	8b69969fbf	Explicit default Matrix constructor. Nothing like this should ever happen: 1*Vector3::yAxis() // 1 converted to true, converted to Matrix3.	14 years ago
Vladimír Vondruš	cceda11957	Fixed all Doxygen C++11 incompatibilities.	14 years ago
Vladimír Vondruš	cbedb9fe61	Fixed more Doxygen C++11 incompatibilities.	14 years ago
Vladimír Vondruš	c8e33a74cc	"constexpr"-ized Matrix and Vector classes. It should improve performance, because what can be computed at compile time is now computed at compile time. In addition these things have been changed or improved: * Removed constructors from T, as they cannot be AFAIK written using constexpr functions only and they only do unnecessary data copying most of the time. The functionality is now provided using static functions Matrix::from() and Vector::from() which returns either const or non-const reference to original data, so no copy is performed. These functions also have explicit warning about unsafe operations. Defaulted copy constructors and assignment operators, using "default initialization" for arrays instead of memsetting it with zeros. It should behave the same and this way we don't need any memcpy(), memset() etc. from <cstring>, which is good.	14 years ago
Vladimír Vondruš	b8f09a0616	Added arithmetic assign operators to Matrix and Vector. Multiplication, division, addition and substraction is now done primarily in assigning operators, as they do the computations in-place, so they are more memory efficient than implementing them using e.g. `this = this+other;`. Updated unit test only for matrix multiplication, as vector unit tests test arithmetic asssign operators too.	14 years ago
Vladimír Vondruš	83150f003e	Using noun instead of verb for inverse matrix function. Mainly to be consistent with Matrix::transposed() function name, furthermore calling Matrix::inverse() could look like the original matrix is being inversed, while calling Matrix::inversed() implies that the function doesn't change the original matrix, but returns the result instead.	14 years ago
Vladimír Vondruš	05107f383b	Doc: some workarounds for Doxygen C++11 support etc.	14 years ago

Vladimír Vondruš	7f24696021	Don't return reference to temporary object in Debug output.	15 years ago
Vladimír Vondruš	31c70f2c08	Doc++	15 years ago
Vladimír Vondruš	0d2f2c966f	Doc++ Updated and simplified Main page of documentation, finally fixed doxygen warnings with @copydoc in Math namespace.	15 years ago
Vladimír Vondruš	8555475807	Support for printing Matrix and Vector to debug output. Added tests for Matrix3, Vector2 just to be sure that debug output works also there.	15 years ago
Vladimír Vondruš	c7b331d100	(Ahem...) Happy New Year!	15 years ago
Vladimír Vondruš	6720bc19f0	Specialization should return also specialized class.	16 years ago
Vladimír Vondruš	e597ad489f	Added Matrix3 specialization (will be needed for normals, lighting etc.).	16 years ago
Vladimír Vondruš	e746fc88c0	Lowered fuzzy compare precision even more Reason for that was that Matrix(m)*Matrix(m).inverse() == Matrix() shouldn't fail with overprecision.	16 years ago
Vladimír Vondruš	dc420e69fc	Even smaller precision for floating point comparison.	16 years ago
Vladimír Vondruš	c41d6ad582	New namespace Magnum::Math.	16 years ago
