Vladimír Vondruš	b4a33d15c3	Math: improve integer/float Vector multiplication and division. Operators that are part of Vector are operating only with the same type as Vector itself, operators for multiplying/dividing integral vectors with floating-point numbers and vectors are now out-of-class and enabled only for integer vectors. It allows better control (e.g. multiplying integer and floating-point vector will _always_ result in floating-point one). Thoroughly tested integer/FP operations and also reworked and tested operator and funciton reimplementations in subclasses, both for value correctness and result type correctness.	13 years ago
Vladimír Vondruš	5ff1020dcd	Math: added Vector::isZero().	13 years ago
Vladimír Vondruš	ac3fe7cdf5	Removed Doxygen workarounds for forward declarations.	13 years ago
Vladimír Vondruš	8debb996a1	Blame the right Windows header for these insane defines. Everyone is fired.	13 years ago
Vladimír Vondruš	0f1142e5ed	Math: added also Matrix[34]::uniformScalingSquared(). Usable to avoid square root and then squaring the value again in spheroid collision detection algorithms.	13 years ago
Vladimír Vondruš	f2840e5880	Math: assert uniform scaling in Matrix[34]::rotation(). Needed to adjust the test cases slightly, because they were firing the assert even if they shouldn't and the "expect fail" case wasn't working at all. I now badly need proper floating-point equality comparison.	13 years ago
Vladimír Vondruš	59be5e26f7	Math: added uniform scaling extraction to Matrix[34].	13 years ago
Vladimír Vondruš	33653a3469	Math: hardened checks for proper size of primitive types.	13 years ago
Vladimír Vondruš	59808c364e	Math: minor test code reorganization.	13 years ago
Vladimír Vondruš	bd00adc437	Math: test copy construction from base classes. Copy construction from the same class should just work.	13 years ago
Vladimír Vondruš	7427292173	Math: test "implicitness" of value constructors.	13 years ago
Vladimír Vondruš	8669907346	Math: merge constexpr test of BoolVector into other test cases.	13 years ago
Vladimír Vondruš	845b8982e5	Reducing pointer chasings, part 2: don't use `this->` so often. It clarifies some things (e.g. from what base given member is). Not changed where it would be too long to write.	13 years ago
Vladimír Vondruš	20dcab0c88	Math: added Matrix[34]::rotationNormalized(). Useful to pass normal matrices to shader, namely with recent commit `b349ca54ad`.	13 years ago
Vladimír Vondruš	56bb116305	Fix loud linker error on mingw32. Mingw for some reasons instantiates depending template before dependent one, causing the dependent one to be instantiated twice.	13 years ago
Vladimír Vondruš	759a28ef45	Math: improved documentation for *::isNormalized().	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	5bbe3df0ef	Math: use both const and constexpr. Spotted by Clang.	13 years ago
Vladimír Vondruš	9ccc63b4aa	Math: fixed strict aliasing warning. Is there _any_ use case of reinterpret_cast where GCC won't loudly complain?	13 years ago
Vladimír Vondruš	5a368c4fba	Math: ability to read and write Rectangle to configuration.	13 years ago
Vladimír Vondruš	3f9d449f58	Math: fix compilation with Clang. It seems that with Clang you cannot split declaration and definition of `constexpr` function. These should be as short as possible anyway, thus it is non-issue.	13 years ago
Vladimír Vondruš	330794d710	Documentation fixes.	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	db05553e65	Math: another C++14 todo :-)	13 years ago
Vladimír Vondruš	316a2d1c37	Math: removed superfluous instantiation sources. Moved all instantiation into instantiation.cpp and removed the rest (~200 lines of mainly license headers). Saves another ~3 seconds (4:06 before, 4:03 now). I'm done with these micro-optimizations for now.	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	fc58631aa5	Math: added convenience function Vector::resized().	13 years ago
Vladimír Vondruš	09ec2006be	Use `\bot` instead of `\perp` in math formulas. `\perp` is for relations, `\bot` is usable as "name". Thanks @JanDupal for hints :-)	13 years ago
Vladimír Vondruš	1f675cae25	Math::Geometry: cleaned up Distance, removed use of Matrix. The same functionality is now provided in Vector2::cross() which is also more meaningful.	13 years ago
Vladimír Vondruš	bf09b037da	Math::Geometry: cleaned up Distance test. Everything is working as expected, which is ahem... unexpected.	13 years ago
Vladimír Vondruš	a4a962f686	Math: fixed matrix tests (spotted by Clang). Either GCC 4.8 poorly implements C++11 or it already has support for some proposed C++14 feature, which allows to elide successive initializer braces.	13 years ago
Vladimír Vondruš	446b108bde	Added TODOs.	13 years ago
Vladimír Vondruš	a21fd0df07	Math: ability to convert matrices from/to external representation.	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	e147cc3992	Doc++, TODO++	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	1402833553	Math: added TODO.	13 years ago
Vladimír Vondruš	3f696533ff	Math: algorithm for computing intersection of two lines in 2D.	13 years ago
Vladimír Vondruš	6385ae1478	Math: more Intersection test cleanup.	13 years ago
Vladimír Vondruš	fd531b5101	Math: cleaned up plane/line intersection. The function now accepts starting point and direction of the line (not starting and ending point). Also improved the documentation and test a bit.	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	7c3cb652bd	Math: doc++	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	a80b4b146d	Math: write Vector2::cross() in terms of perpendicular() and dot().	13 years ago
Vladimír Vondruš	49154f30c4	Math: added Vector2::perpendicular(). Also updated and crosslinked related documentation.	13 years ago
