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	186c522fe5	Math: added lerpInverted().	13 years ago
Vladimír Vondruš	5787d66d45	Math: test also vector as interpolation phase in Math::lerp().	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	f6ae87376b	Math: added function fma().	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	5e8606a755	Math: added sign() function.	13 years ago
Vladimír Vondruš	f91f464ec8	GCC 4.4 compatibility: better solution for explicit conversion of Unit. Having implicit conversion on Unit class causes much more harm than doing the conversion some other way -- mainly for multiplication and division, which is done with builtin operators and thus the result is unitless. Also it is possible to do wrong "retyping" between degrees and radians: Rad a = Constants::pi(); Deg b(a*2); On GCC >4.5 b is `180`, but on GCC 4.4 it is `2pi`, which is obviously wrong and not wanted. The conversion is done using Unit::toUnderlyingType() which is now used everywhere instead of conversion operator. The conversion operator is made available only for GCC 4.5, where it can be marked as explicit. This might cause incompatibilites with `master` branch, where no Unit::toUnderlyingType() exists, but users should have no need to convert it to underlying type anyway as all required functions are available through the library. This reverts commit `36ac4de5c4` and partially also `0db3a183ae` (UnitTest.cpp).	13 years ago
Vladimír Vondruš	0db3a183ae	GCC 4.4 compatibility: issues with lack of explicit conversion operators.	13 years ago
Vladimír Vondruš	d95c44fcc8	Math: test that trigonometric functions work with Unit base class. The test fails.	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	35eb876303	Various other compilation fixes for OpenGL ES target.	13 years ago
Vladimír Vondruš	4744b631bb	Math: test pow() constexpr.	13 years ago
Vladimír Vondruš	c5ab86794b	Relicensing to MIT/Expat license, part 3: source files. Added license header also to shader sources. Hopefully it won't harm compilation times too much.	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	231f3277ab	Adapted to Corrade changes. Allowing to instantiate Trade::AbstractImporter subclasses directly without plugin manager.	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
Vladimír Vondruš	0144c38a54	Math: moved lerp() from Vector to Functions.h. It does nothing special for vectors (unlike e.g. quaternion LERP) and scalar overload is useful too.	13 years ago
Vladimír Vondruš	8a63939134	Math: added vector/scalar abs() function.	13 years ago
Vladimír Vondruš	263d8351b6	Math: vector overloads for normalize() and denormalize().	14 years ago
Vladimír Vondruš	4d6d3fde88	Math: scalar/vector implementation of min(), max() and clamp(). This is gonna be some ugly template hell.	14 years ago
Vladimír Vondruš	cade175304	Math: finally implemented precise signed/unsigned normalization. (De)normalization from/to [0, 1] for unsigned types and from/to [-1, 1] for signed types. -1.0 is always denormalized to min+1. Also updated some tests for Color, as they depended on previous imprecise implementation.	14 years ago
Vladimír Vondruš	7dc0fc4a4c	Math: Renamed Math.h to Functions.h Math.h is reserved for forward declaration header.	14 years ago
Vladimír Vondruš	52300cf402	Math: function for base-2 logarithm. Verbatim copy from Corrade, might be better to have it here too (possibly some SIMD optimizations?).	14 years ago
Vladimír Vondruš	fcb8a7b768	Got rid of header files in tests. They have no practical use and they only bloat codebase size and add maintenance burden.	14 years ago
Vladimír Vondruš	0f889369f4	No `using namespace std` anywhere. Also added missing std:: prefix to remaining cases of std::size_t, std::[u]int[0-9]+_t, std::sin() etc., std::exit().	14 years ago
Vladimír Vondruš	c1cf94fb46	Using fixed-size integer types also everywhere else. It solves issues with int/long int/long long int ambiguity, which is good.	14 years ago
Vladimír Vondruš	eb803200d6	Disabled denormalization test for long double altogether. Fails in Debug, but passes in Release mode on my GCC 4.7 @ x86_64. Not sure what to do about it.	14 years ago
Vladimír Vondruš	3d77885555	Revert "Overflow test for large types in Math::normalize() started working." It was working because of some weird state of my build dir, expecting fail again. This reverts commit `75d0505a60`.	14 years ago
Vladimír Vondruš	75d0505a60	Overflow test for large types in Math::normalize() started working. I don't know what caused that... :-)	14 years ago
Vladimír Vondruš	fe62f547de	Reduced #includes in headers. Magnum.h now doesn't include anything except OpenGL headers, thus changes in Math library don't trigger recompilation of everything, but only of things really depending on it. Math constants moved to separate file for similar reasons, de-inlined some functions to remove the need for some #includes.	14 years ago
Vladimír Vondruš	3558859cc6	Utility function for clamping value in given limits.	14 years ago
Vladimír Vondruš	51f2478b1e	More precise double Math constants. Double has 15-17 significant decimal digits precision, extended the constant to have 15 decimal digits. On the other hand, float has only 6-9 digits, so there is no need to have more than 9. Added just-to-be-sure test for sqrt* constants.	14 years ago
Vladimír Vondruš	3bcaed6322	Using round() in denormalization. Gives more precise results for smaller types, but creates overflow for large types.	14 years ago
Vladimír Vondruš	2553e50444	Functions for normalizing and denormalizing numeric values.	14 years ago
Vladimír Vondruš	27e1dce533	Got rid of Qt's QtTest in favor of Corrade's TestSuite. Now we can use CORRADE_COMPARE() almost exclusively for comparing Vector, Matrix instances and all containers from STL. Tests running time for all 31 tests is now around 0.1 sec instead of two seconds like before. Disabled compilation of all benchmarks, because TestSuite cannot handle them yet. PKGBUILD from AUR now can shamelessly use check() function without unnecessary dependencies.	14 years ago
Vladimír Vondruš	7f6f81afc7	Math::Constants are now inline functions instead of static variables. Static variables were compiled into the library and then linked on every use, which was not good for performance.	14 years ago
Vladimír Vondruš	925cc3d2ff	Make Math::pow() templated on type.	14 years ago
Vladimír Vondruš	f0d88fbf9f	Added templated Math::Constants structure to replace PI #define. And added sqrt(2) and sqrt(3) constants while we are at it.	14 years ago
Vladimír Vondruš	c14715962d	Use T() instead of static_cast<T>() for numeric types.	14 years ago
Vladimír Vondruš	b945f5f68b	Happy New Year.	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	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
