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	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
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	5819dd4bd7	Math: matrix/vector rework, part 3: conversion as explicit constructor. Also updated all dependent classes to follow the change, such as Color and Rectangle. Backwards compatibility for GCC 4.6 (with lack of support for delegating constructors) will be done as non-constexpr constructor using operator=().	13 years ago
Vladimír Vondruš	263d8351b6	Math: vector overloads for normalize() and denormalize().	13 years ago
Vladimír Vondruš	ec23a3d13c	Minor code cleanup.	13 years ago
Vladimír Vondruš	ad9a55a867	Doc++	13 years ago
Vladimír Vondruš	4d6d3fde88	Math: scalar/vector implementation of min(), max() and clamp(). This is gonna be some ugly template hell.	13 years ago
Vladimír Vondruš	bdba6b7221	Math: no need to have two versions of denormalize(), they are the same. Overlooked in `cade175304`.	13 years ago
Vladimír Vondruš	3daefd70a9	Math: simplified internal pow<n>() implementation.	13 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	7183110eee	Doc++, @todo++	14 years ago
Vladimír Vondruš	c7d7fdad28	Math: removed done TODO.	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	cdc2e5302c	Using fixed-size 32bit integer instead of size_t for log/pow. I want something like "use 32bit on x86, but 64bit on x86_64 and x86_32", but <cstdint> header has nothing like that.	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	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	d96cb96d60	Documented convenience functions on vectors and angles.	14 years ago
Vladimír Vondruš	eeca90c17c	Added @todos .	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	45d1cb1225	Anonymized unused function parameters.	14 years ago
Vladimír Vondruš	6f65dd972c	Renamed visibility configuration headers to resemble library names.	14 years ago
Vladimír Vondruš	4af08d04c1	Renamed visibility headers to distinguish them from API headers. Also added note about that to coding style documentation.	14 years ago
Vladimír Vondruš	952f8ebb27	Compiling with -fvisibility=hidden. Reusing macros MAGNUM_EXPORT and friends already used for Windows builds. For exported classes added MAGNUM_LOCAL to private members which are not referenced from any inline function. Added explicit MAGNUM_EXPORT to private members which are referenced. CMake provides its own macro <target>_EXPORTS, using that instead of set_target_properties().	14 years ago
