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	a3b754b88e	Possiblity for constructing Vector from one value, like in GLSL. Marked the constructor as explicit, because we don't want mistakes like this to happen: Matrix4::rotation(1.0f, deg(3.0f)); // oops, swapped axis and angle! Instead, when calling such constructor, the type must be said explicitly (initializer-list is forbidden, too): Matrix4::rotation(deg(3.0f), Vector3(1.0f)); // okay	14 years ago
Vladimír Vondruš	d1dd06aa0a	Ability to explicitly specify precision for floating-point equality.	14 years ago
Vladimír Vondruš	3495738fc0	Removed memcpy() from Matrix::set(), using Vector::from() in Matrix::at().	14 years ago
Vladimír Vondruš	7c857ccb16	Better implementation for Matrix::determinant() using external functor. Removes lots of unmaintained and duplicated code from Matrix<T, 2> template specialization.	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	5bfdac108c	Added some TODOs.	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	8761e1f636	Using "initializer-list" constructors for Matrix everywhere.	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	1cf69616a3	Documentation updates, "markdownization". All HTML code and Doxygen shortcuts such as @c, @b and @em are now rewritten using Markdown syntax, which makes it more readable. Also updated Doxyfile. Doxygen 1.8 at least is required to generate the documentation now.	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	1f2aa86be3	Fixed awesome bug in Vector3 constructor. Updated unit test to make sure it won't happen again.	14 years ago
Vladimír Vondruš	05107f383b	Doc: some workarounds for Doxygen C++11 support etc.	14 years ago
Vladimír Vondruš	b6ac0125dc	"Initializer-list" constructor also for Matrix.	14 years ago
Vladimír Vondruš	f8d44a19ed	Removed wrong TODO. Math types cannot be implicitly shared, because they often need to be casted to float[], for example.	14 years ago
Vladimír Vondruš	7a03e48df8	Finally "initializer-list" constructor for Vector. It's not actually initializer list, because it is only for variable-length types, which is unusable here. Variadic templates do better job here.	14 years ago
Vladimír Vondruš	7911c22eff	Removed convenience functions with "unwrapped" Vector parameters. With C++11, objects can be passed nearly as easy as without these convenience functions, for example: Matrix4::scaling({0.5f, 1.0f, 0.5f}); which is nearly the same as the following, using convenience function: Matrix4::scaling(0.5f, 1.0f, 0.5f); Convenience functions can also be pretty confusing, for example: Matrix4::rotation(1.0f, -1.0f, 2.0f, 2.0f); // wtf? Matrix4::rotation(1.0f, {-1.0f, 2.0f, 2.0f}); // ah, okay! There are also a few neat tricks, which cannot be done using convenience functions, for example: Matrix4::translate(Vector3::xAxis(3.0f)); // {3.0f, 0.0f, 0.0f} Camera::setClearColor({0.1f, 0.1f, 0.1f}); // default 1.0f for alpha	14 years ago
Vladimír Vondruš	28adf2c98b	Added length parameter to Vector3::[xyz]Axis(). Now you can write e.g. Matrix4::translation(Vector3::xAxis(5.0f)); instead of these: Matrix4::translation(Vector3::xAxis()*5.0f); // slow! Matrix4::translation({5.0f, 0.0f, 0.0f}); // boring!	14 years ago
Vladimír Vondruš	aedc90e712	Doc++ Fixed mainly unwanted Doxygen autolinks.	14 years ago
Vladimír Vondruš	9e81d4b6c3	Fixed awesome mistake in Math::TypeTraits. Epsilon value for integral types should be 1, not 0. Updated documentation and test to reflect the change.	14 years ago
Vladimír Vondruš	c1374155b0	Math: function to compute product of all values in the vector. Is this mathematic operation at all?	14 years ago
Vladimír Vondruš	8efb5a1e42	Added dllimport/dllexport macros for Windows builds.	14 years ago
Vladimír Vondruš	8d525be511	Using TypeTraits::epsilon and TypeTraits::equals instead of EPSILON. Improves comparison performance on integral Matrix and Vector, fixes NaN comparison bug (but infinity bug is still present).	14 years ago
Vladimír Vondruš	f585d39146	Added Math::TypeTraits, implementing fuzzy comparison based on type. Fuzzy comparison is implemented only on floating-point types with type-specific epsilon, on integral types classic operator== is used. TypeTraits class is now extension of Math::TypeTraits (where it makes sense).	14 years ago
Vladimír Vondruš	e0b4fca4fe	Doc++ Removed doc/namespaces.dox, moved namespace documentation to main files of given namespace.	15 years ago
Vladimír Vondruš	b945f5f68b	Happy New Year.	15 years ago
Vladimír Vondruš	9f8bb86dbb	Preserve space before and after printing Matrix/Vector to Debug output. Modified unit tests to check that.	15 years ago
Vladimír Vondruš	7f24696021	Don't return reference to temporary object in Debug output.	15 years ago
Vladimír Vondruš	cb0efb5d47	Vector3 constructor from Vector2 and optional Z/B value (default 0).	15 years ago
Vladimír Vondruš	31c70f2c08	Doc++	15 years ago
Vladimír Vondruš	eaf7232943	Don't compile Math as static library, as unused symbols are discarded. Currently the files are compiled directly into Magnum library, static library is used only for testing purposes.	15 years ago
Vladimír Vondruš	e536c892c4	Added Math::pow() and Math::log() functions. Math::pow() is templated on exponent, so it should be as fast as possible (without recursion).	15 years ago
Vladimír Vondruš	e74168bb88	Added test for Math::deg() and Math::rad().	15 years ago
Vladimír Vondruš	be3dd97d0a	Renamed Math/{constants.h => Math.h}.	15 years ago

Vladimír Vondruš	03289b18ac	Doc++	15 years ago
Vladimír Vondruš	3c1f5392e8	Useful functions for making angle entering less error-prone. Both functions convert the value to radians at compile time. For example deg(180.0f) is converted to 3.14f. Less intuitive than user-defined literals (C++11 feature), but works everywhere.	15 years ago
Vladimír Vondruš	58ace7d678	Fixed errors with template two-phase lookup, discovered with GCC 4.7.	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	614373e1af	Magnum now depends on Corrade. Corrade will provide necessary things like plugin management and many other useful utilities.	15 years ago

Vladimír Vondruš	b27d5efc04	Propagated dot product operator to Vector specializations. Otherwise GCC doesn't see the operator.	15 years ago
Vladimír Vondruš	79aabfc0cc	Store template parameters in Vector class for later retrieving.	15 years ago
Vladimír Vondruš	c7b331d100	(Ahem...) Happy New Year!	15 years ago
