Vladimír Vondruš	fede9f3f8d	Math: fix test compilation on XCode. See file comment for details. Yet another instance of the problem described in #37.	10 years ago
Vladimír Vondruš	b777135116	MSVC 2015 Update 1: in-class constexpr initialization works now.	11 years ago
Vladimír Vondruš	6e8c16c960	MSVC 2015 Update 1: fixed nearly all constexpr bugs.	11 years ago
Vladimír Vondruš	40a12441c0	Math: haha, pushed without test. Kill me.	11 years ago
Vladimír Vondruš	6e73dee096	Math: avoid dependency on Functions.h in DualQuaternion.h. Is it still justifiable to do things like this or am I too paranoid about compilation times now?	11 years ago
Squareys	0e05c7289e	Math: Fix sclerp of dual quaternions with equal rotation and add test. When rotation is identical, the rotation of the first dual quaternion is returned instead, together with the linearly interpolated translation of both (lerp of the vectors of the dual part). The additional include is needed for `Math::lerp(Vector<3, T>, Vector<3, T>, T)`. Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Vladimír Vondruš	9ebd6ad46d	Math: added pow(), log() and exp(). Just wrappers around std::pow(), std::log() and std::exp() to have the complete toolbox consistent.	11 years ago
Vladimír Vondruš	ab35741221	Math: minor cleanup, reordering and test renaming.	11 years ago
Vladimír Vondruš	d91cb8f9e8	Disallow default construction of tag types. Caused ambiguous overload problems when using {} in function calls. The tags should be always specified explicitly.	11 years ago
Vladimír Vondruš	2d44f46f14	Math: fix compiler warning.	11 years ago
Vladimír Vondruš	247d8dba6f	Math: added lerp(T, T, BoolVector). In GLSL this is called mix() and I thought this is there for a long time, but apparently it got included only in GL 4.5 / ES 3.1.	11 years ago
Vladimír Vondruš	e6567af364	Math: don't depend on char signedness in test. Hopefully that was only in the test.	11 years ago
Vladimír Vondruš	7bb8bb271b	Math: test Quaternion SLERP division by zero with non-trivial data. So that we test it returns the first argument and not default-constructed value or something. Also updated the documentation.	11 years ago
Squareys	998f63bcb2	Math: Fix slerp interpolation of equal quaternions and add test. If and only if the quaternions to interpolate are equal, the angle between them is 0.0 and we therefore cannot safely divide by the sin of that angle. Credits to @wivlaro for finding this one. Fixes #117. Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Vladimír Vondruš	58f16ccdb5	Math: proper fuzzy-compare for std::pair<float, float>. I should update TestSuite to handle this automagically.	11 years ago
Vladimír Vondruš	06a1734b86	MSVC 2015 compatibility: {}-related issues.	11 years ago
Vladimír Vondruš	35d2e2c370	Math: simplified DualQuaternion ScLERP. Making use of sincos() for Dual numbers, constructing DualQuaternion from dual vector and scalar parts and using DualQuaternion::isNormalized(). Also updated the math equation to be consistent with conventions elsewhere.	11 years ago
Vladimír Vondruš	0f14be471e	Math: ability to construct DualQuaternion from dual vector and scalar. As opposed to real and dual quaternion.	11 years ago
Vladimír Vondruš	609df779f5	Math: added sincos() for Dual numbers. Calculating sin of Dual number involves also calculating the cos value, thus a helper function is in order.	11 years ago
Vladimír Vondruš	ce9be12708	Math: ability to multiply and divide dual and real number.	11 years ago
Vladimír Vondruš	34df5a0aaa	Math: explicit conversion constructors for Dual, Complex and Quaternion. Similarly to what's already in all Vector and Matrix classes. Not sure why this wasn't there already.	11 years ago
Vladimír Vondruš	e7cae67e9f	Math: added sincos(). Mainly a convenience function in case you want to compute sin and cos of the same, potentially longer expression, and you don't want to have repeated code or temporary variables. On some architectures might use faster instruction that computes both values in one shot.	11 years ago
Vladimír Vondruš	5160779e5e	Math: doc++	11 years ago
Vladimír Vondruš	fb1cbd416d	Math: document implementation reasons.	11 years ago
Squareys	cbcb18ddc3	Math: Use a more readable notation for inline comments. This should be alot easier to read than the TeX code before. Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Squareys	ae07f15676	Math: Super minor formatting fix. Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Squareys	ff593b1faf	Math: Cleanup ScLERP implementation. - Use explicit conversion to `T` - Use `std::` for `acos, cos, sin` to avoid use of double only functions - Do not mutate variables in math code to avoid confusion Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Squareys	4d077c878e	Math: Add inline comments to reference the TeX formula from code. Should help people understand the code and counteracts the unreadability caused by the optimization commit at least a bit. Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Squareys	22f2c38132	Math: Optimize ScLERP implementation. Optimized with simple code tricks, some very complex math (like `2*0.5=1`), and principal of locality. Things the compiler would probably do for me anyway. Was able to remove about 6 useless float multiplications. Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Squareys	7d78c7b30e	Math: Implement DualQuaternion screw interpolation (ScLERP). Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Squareys	9c055d0348	Math: Add test for DualQuaternion screw interpolation (ScLERP). A test driven approach to this abstract math stuff. Signed-off-by: Squareys <Squareys@googlemail.com>	11 years ago
Vladimír Vondruš	b87917a1e1	Math: fix build on Clang and GCC < 5.2. MSVC 2015 worked flawlessly. I don't know what error is a compiler bug and what's okay anymore.	11 years ago
Vladimír Vondruš	62203ae891	Math: proper multiplication/division of Duals with different types. Now works both ways. The base class works with virtually any combination that is supported by the underlying types, so e.g. Dual<Matrix3<T>> could be multiplied/divided with Vector3<T> (result is Vector3<T>), with Matrix3<T> (result is Matrix3<T>) or with T (result is Matrix3<T>). The macros, on the other hand, because they are there only to help with implementation of my subclasses, restrict that to the two only cases I need (i.e. multiplication with Dual<T> and Dual<T::Type> and nothing else). Could be extended in the future if it needs to be.	11 years ago
Vladimír Vondruš	d3f528093e	Math: avoid copypaste code in DualComplex. Ugh this class is ugly (but works!).	11 years ago
Vladimír Vondruš	1becbae4ec	Math: test Dual subclass implementation macro. Not sure why I did not do this already.	11 years ago
Vladimír Vondruš	d5359a2c36	Math: update and document subclass implementation macro tests.	11 years ago
Vladimír Vondruš	2c34110aa9	Math: better qualification of types in Dual subclass implementation macro.	11 years ago
Vladimír Vondruš	82b40944ac	Math: test multiplication/division of Dual numbers with different type. Only one multiplication order works currently, which is wrong.	11 years ago
Vladimír Vondruš	a535f7ab47	Math: ability to access Dual members via reference. Not sure why that was omitted.	11 years ago
Vladimír Vondruš	670c9d0763	Adapted to Corrade::Utility::Debug changes.	11 years ago
Vladimír Vondruš	0aa16595eb	Use new-style debug operators everywhere.	11 years ago
Vladimír Vondruš	f2e20ba5c0	Math: default alpha parameter also for Color4::fromHSV(). Not sure why this was omitted.	11 years ago
Vladimír Vondruš	127f34b657	Math: fix typedef shadowing.	11 years ago
Vladimír Vondruš	5391ab247e	Math/Algorithms: fix variable shadowing.	11 years ago
Vladimír Vondruš	86c8fdef8d	Fix linking of tests on MinGW-w64 GCC 5.1. It worked flawlessly when crosscompiled from Linux, but compiling that natively causes the linker to loudly complain about undefined references to ConfigurationValue structs. I think it worked well under 4.9.2 (but that mess had a slew of other ugly problems, such as complete inability to produce non-crashing C++11 code under x64). The linker error is caused only because I tried to reduce binary bloat, so I'm just disabling that for MinGW and screw that. No problem under MSVC.	11 years ago
Vladimír Vondruš	54fc071d2b	MSVC 2015 compatibility: NaN is not constexpr. It probably complains only because one of them (the float one) is constexpr and the other is not. Whatever.	11 years ago
Vladimír Vondruš	eac01167f5	MSVC 2015 compatibility: except long double (de)normalization to fail. I'm giving up on this one also for 2015. Cherry-picked from compatibility branch (6ee931b7b492c12cd6674c93564617c7139cea84).	11 years ago
Vladimír Vondruš	bfbacaa7c9	MSVC 2015 compatibility: random stuff that's causing compiler crashes. Random indeed. In particular, it's causing crashes for Vector2 and Vector3, but not for the exact same code in Vector4!	11 years ago
Vladimír Vondruš	b2604bb903	MSVC 2015 compatibility: issues with delegating constexpr tag constructors. Fixed-size constructors were worked around, the rest is now impossible to have constexpr.	11 years ago
Vladimír Vondruš	9136007371	MSVC 2015 compatibility: apparently dereferencing pointer is verboten.	11 years ago
