Vladimír Vondruš	3b5e650af5	Math: fix compilation of tests under libc++. std::forward() is not constexpr in C++11.	11 years ago
Vladimír Vondruš	911ed52413	Math: test constexpr-ness of subclass types. Fails with libc++ because std::forward() is not constexpr in C++11 (yes, I'm adding the test solely because of that).	11 years ago
Vladimír Vondruš	1d9e6210d8	Use anonymous typed enum instead of static const member variable. The reason behind this is that it's not possible to take address of the enum value -- the generated code can be simpler and no symbol is exported.	11 years ago
Vladimír Vondruš	d0baab2bfe	I hate GCC. Why the hell it does not have std::is_trivially_constructible until version 5?!	11 years ago
Vladimír Vondruš	838eb180fc	Fix compilation on Clang.	11 years ago
Vladimír Vondruš	c4bf8d6eda	Doxygen workarounds. I LOVE this, do you hear me? Especially at 2:40 AM.	11 years ago
Vladimír Vondruš	350d820823	Math: cleanup.	11 years ago
Vladimír Vondruš	413e2e6735	Math: properly test that these constructors are indeed implicit.	11 years ago
Vladimír Vondruš	1b0da5b2df	Math: ability to construct all types without initializing the contents. Useful for squeezing out last bits of performance, e.g. in this case: Vector3 a; a[0] = something++; a[1] = something++; a[2] = something++; In the code all elements are first zeroed out and then overwritten later, thus it might be good to avoid the zero-initialization: Vector3 a{Math::NoInit}; a[0] = something++; a[1] = something++; a[2] = something++; This will of course be more useful in far larger data types and arrays of these.	11 years ago
Vladimír Vondruš	702c9db6b4	Math: ability to zero-initialize all classes. Previously only matrices allowed to be created either as an identity or zero-initialized. Now all Math classes support that, including (dual) complex numbers and quaternions.	11 years ago
Vladimír Vondruš	3a8ac02909	Math: more explicit default zero/identity constructors. Some classes are by default constructed zero-filled while other are set to identity and the only way to to check this is to look into the documentation. This changes the default constructor of all classes to take an optional "tag" which acts as documentation about how the type is constructed. Note that this result in no behavioral changes, just ability to be more explicit when writing the code. Example: // These two are equivalent Quaternion q1; Quaternion q2{Math::IdentityInit}; // These two are equivalent Vector4 vec1; Vector4 vec2{Math::ZeroInit}; Matrix4 a{Math::IdentityInit, 2}; // 2 on diagonal Matrix4 b{Math::ZeroInit}; // all zero This functionality was already present in some ugly form in Matrix, Matrix3 and Matrix4 classes. It was long and ugly to write, so it is now generalized into the new Math::IdentityInit and Math::ZeroInit tags, the original Matrix::IdentityType, Matrix::Identity, Matrix::ZeroType and Matrix::Zero are deprecated and will be removed in the future release. Math::Matrix<7, Int> m{Math::Matrix<7, Int>::Identity}; // before Math::Matrix<7, Int> m{Math::IdentityInit}; // now	11 years ago
Vladimír Vondruš	5bc87addab	Math: added header with tags. Will be used to distinguish various kinds of construction.	11 years ago
Vladimír Vondruš	25486a7ac4	Math: properly prefix private variables.	11 years ago
Vladimír Vondruš	2ecbef1355	Math: yet another Doxygen workaround. I now have at least fifty Doxygen bugs waiting to be reported and I'm laaazy to do thaat.	11 years ago
Vladimír Vondruš	562d71dbe6	Math: ability to convert ranges from/to external representation.	11 years ago

Vladimír Vondruš	1a389f7a00	Math: work around bug in GCC 5.1 which broke the tests. Reported here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66450 .	11 years ago
Vladimír Vondruš	52434fb55c	Math: ability to convert dual quaternions from/to external representation. Still undocumented feature.	11 years ago

Vladimír Vondruš	fa3ec12dba	Math: actually test the conversion and not some random copy constructor.	11 years ago
Vladimír Vondruš	4027874b8d	Math: cleanup.	11 years ago
Vladimír Vondruš	f8e2ebed00	Math: test NaN comparison behavior of Unit class. Passes, obviously. What was I thinking.	11 years ago
Vladimír Vondruš	4f90760598	First-class WebGL support, part 1: initial infrastructure.	11 years ago
Vladimír Vondruš	b2d7f4ecc7	Revert "Math: use Vector::max() instead of custom ugly solution." This reverts commit `71db38cb2f`. The test passes again.	11 years ago
Vladimír Vondruš	dd2fde5ae0	Math: improve QuaternionTest to verify all quaternion-from-matrix cases. The test fails. I was able to craft inputs so that all cases were passing even with the obviously wrong algorithm. Huh.	11 years ago

Vladimír Vondruš	6e177780b0	Math: fixed test compilation with libc++. Apparently std::forward() is constexpr only in C++14. Heh.	11 years ago
Vladimír Vondruš	2e068e233b	Math: fixed Clang build. Caused by careless change in previous commit.	11 years ago
Vladimír Vondruš	64bc2393d1	Math: made dot(), angle(), *lerp() and cross() free functions. It is often annoying to write e.g. this, especially in generic code: T dot = Math::Vector<size, T>::dot(a, b); When this is more than enough and the compiler can infer the rest from the context: T dot = Math::dot(a, b); There are more downsides and confusing cases (you can call Math::Vector<3, T>::dot(), Math::Vector3<T>::dot() and Color3::dot() and it is still the same function), so I made these as free functions in Math namespace. You can now also abuse ADL for the calls, but I would advise against that for better readability: T d = dot(a, b); // dot?! what on earth is dot? and what is a? The only downside found when porting is that you need to specify the type somehow when having both parameters as initializer lists: T d = dot({2.0f, -1.5f}, {1.0f, 2.5f}); // error T d = dot(Complex{2.0f, -1.5f}, {1.0f, 2.5f}); // okay But that's probably reasonable (and it's also highly corner case, the functions were used this way only in tests). The original static member functions are of course still present, but marked as deprecated and will be removed at some point in future.	11 years ago
Vladimír Vondruš	7be1239adf	Math: improve docs for vector cross/dot product. Comes handy. In my case to prevent more embarassing mistakes in the future.	11 years ago
Vladimír Vondruš	65a2e5677a	Properly use the "Std Swap Two Step". I hate this. Why it isn't intuitive like proposed in here? http://ericniebler.com/2014/10/21/customization-point-design-in-c11-and-beyond/	11 years ago
Vladimír Vondruš	b121e8758a	Math: added Vector::pad().	11 years ago
Vladimír Vondruš	6372711260	Math: save one swizzle in Vector3::cross(). There was also an error in the original equation (docs only, though).	11 years ago
Bill Robinson	80e01ae18d	Math: added Matrix4::lookAt().	11 years ago
Vladimír Vondruš	90b519c4d2	Math: improve Constants test, fix Clang compilation.	11 years ago
Vladimír Vondruš	f30a4677eb	Math: added Matrix[34]::shearing*().	11 years ago
Vladimír Vondruš	c71dc12503	Making test declarations more compact. Yet again I experienced how insanely large this thing got over the years.	11 years ago
Vladimír Vondruš	6488fe6e75	Oh, it's 2015 already.	11 years ago

Vladimír Vondruš	c56940993b	Use the new math constants throughout the code.	12 years ago
Vladimír Vondruš	00124f65eb	Math: return unspecified value after an assertion. The user shouldn't expect anything after assertion anyway and it only adds unnecessary noise to the implementation and tests.	12 years ago
Vladimír Vondruš	75c3e00844	Math: added NaN and infinity to constants. Using std::numeric_limits for the Double variants looks like an overkill to me, but there apparently isn't any other way, except for crafting the value manually using the exact binary representation (and hoping it will be portable) or producing the value as result of division by zero or something like that (and then working around the warnings and also hoping it will be portable).	12 years ago
Vladimír Vondruš	076144886a	Math: added half pi and Euler's number to constants. Constants::piHalf() is not longer to write than doing the division manually and it has significantly smaller mental overhead. Also I chose piHalf() instead of halfPi() to make it more discoverable through autocompletion. Float a = Constants::pi()0.5f; Float a = Constants::piHalf(); Float b = Constants::pi()/(2countOfSomething); Float b = Constants::piHalf()/countOfSomething;	12 years ago
