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
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	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	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	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
Vladimír Vondruš	a58121e893	Math: added div() function.	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	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	6488fe6e75	Oh, it's 2015 already.	11 years ago
Vladimír Vondruš	64a02d68db	Math: document more non-obvious tricks.	12 years ago
Vladimír Vondruš	8be3630432	Math: doc++	12 years ago
Vladimír Vondruš	81039fc2c9	Math: completed documentation review.	12 years ago
Vladimír Vondruš	2235cb76b1	Apparently Android is something like newlib.	12 years ago
Vladimír Vondruš	6f0ba96cb6	Happy new year too.	12 years ago
Vladimír Vondruš	7a68362170	Making includes absolute, part 6: better filenames for internal files. As we are now using absolute includes, there is no need to prefix everything with "magnum<Namespace>" etc. All generated configuration files are renamed to configure.h and their path is included _before_ everything else to avoid accidental collisions.	12 years ago
Vladimír Vondruš	0616f24f34	Making includes absolute, part 5: absolute includes everywhere. The only places where they aren't absolute are: - when header is included from corresponding source file - when including headers which are not part of final installation (e.g. test-specific configuration, headers from Implementation/)	12 years ago
Vladimír Vondruš	45a10cefdf	Making includes absolute, part 1: moving files around. Everything what was in src/ is now in src/Corrade, everything from src/Plugins is now in src/MagnumPlugins, everything from external/ is in src/MagnumExternal. Added new CMakeLists.txt file and updated the other ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED is set, everything compiles and installs like previously except for the plugins, which are now in MagnumPlugins and not in Magnum/Plugins.	12 years ago
Vladimír Vondruš	282ee58c62	Math: work around missing std::round() in NaCl newlib. Also test that our implementation behaves the same.	13 years ago
Vladimír Vondruš	ee045d261a	Make some type conversions explicit. Fixes a bunch of MSVC warnings.	13 years ago
Vladimír Vondruš	4059bd752f	Math: added minmax() and Vector2::minmax(). No Vector<size, T> and std::initializer_list versions yet, as the algorithm for it is pretty complicated and I'm not sure that they will be used frequently enough to deserve their existence.	13 years ago
Vladimír Vondruš	f009e5c47f	Math: added rounding functions.	13 years ago
Vladimír Vondruš	d6586fa1fc	Math: reduce code duplication in Functions.h.	13 years ago
Vladimír Vondruš	de2ca00217	Math: doc++	13 years ago
Vladimír Vondruš	186c522fe5	Math: added lerpInverted().	13 years ago
Vladimír Vondruš	06a4e297bc	Math: deinlined heavy functions, removed redundant `inline`. Also fixed unary RectangularMatrix::operator-() and Vector::operator-() documentation (was stating that the operation is done in-place, which is impossible.	13 years ago
Vladimír Vondruš	a63fea570a	Math: don't include <algorithm> in header file. `31ce072f39` was wrong, this header is harmful. This beast includes ~46k LOC, much more than <*stream> class of headers. Rewritten min() and max() manually, which surprisingly leads to shorter implementation than previously. Compilation time on my machine reduced from ~4:30 to ~4:21, not bad.	13 years ago
Vladimír Vondruš	31ce072f39	Math: added initializer list overloads for min() and max(). Hopefully including <algorithm> doesn't do much harm to compilation time.	13 years ago
Vladimír Vondruš	2447ca9fb5	Added some TODOs.	13 years ago
Vladimír Vondruš	7ef8432fbe	Doxygen: ignore specific namespaces instead of whole directories. Less maintenance burden with `#ifndef DOXYGEN_GENERATING_OUTPUT`, removed the ones which are not needed anymore.	13 years ago
Vladimír Vondruš	458e146765	Math: std::fma() is not available in NaCl's newlib.	13 years ago
Vladimír Vondruš	f6ae87376b	Math: added function fma().	13 years ago
Vladimír Vondruš	4ab3ab6534	Math: added Vector::lengthInverted(). Also because there are SIMD instructions for that.	13 years ago
Vladimír Vondruš	6124ad3c27	Math: added sqrtInverted() function. There are SIMD instructions for that, so why not have it in place.	13 years ago
Vladimír Vondruš	bf58bb3cb1	Math: rework of component-wise matrix and vector functions. First, removed functions which can be done with Vector's member functions and functions from Functions.h. More flexibility and less redundant code which leads to easier SIMD implementation later. Vector4 a; Float b = a.maxAbs(); // before Float b = Math::abs(a).max(); // now Second, removed all functions from RectangularMatrix which are implemented in Vector and added conversion from RectangularMatrix to Vector and back. Also for more flexibility and less redundant code (i.e. reusing SIMD-optimized Vector::max() instead of writing it again). Matrix4x3 a; Float b = a.max(); // before Float b = a.toVector().max(); // now	13 years ago
Vladimír Vondruš	b0883f8d6b	Doc++	13 years ago
Vladimír Vondruš	5e8606a755	Math: added sign() function.	13 years ago
Vladimír Vondruš	56139ae365	Math: no need to provide implementation just for Doxygen.	13 years ago
Vladimír Vondruš	2d71c86942	Math: make trignometric functions working with Unit base class. The test now passes again.	13 years ago
Vladimír Vondruš	83bda8bbe6	Math: fixed test for denormalize<UnsignedLong, long double>(). Amazing what single forgotten literal can do.	13 years ago
Vladimír Vondruš	6a5d75d1e4	Relicensing to MIT/Expat license, part 2: headers.	13 years ago
Vladimír Vondruš	90a60ce7e9	Math: disable denormalize() test for UnsignedLong. It works with GCC and -O3, but fails on unoptimized code.	13 years ago
Vladimír Vondruš	6a90b0231b	Math: using new aliases for builtin types in whole Math namespace.	13 years ago
Vladimír Vondruš	5ff0e29950	Math: fix warning about literal types in normalize(). C++11 changed type of character literal (i.e. '\x7F') from int to char, thus the documentation is wrong (also mistakenly used octal literal). Added test to properly test the behavior.	13 years ago
Vladimír Vondruš	c2f4359bd7	Math: added strongly-typed asin(), acos() and atan().	13 years ago
Vladimír Vondruš	c0a5e5dadd	Math: added sin(), cos() and tan() accepting either Rad or Deg.	13 years ago
Vladimír Vondruš	fec6822187	Math: added sqrt() scalar/vector overload.	13 years ago
