Vladimír Vondruš	56a3aebf73	Math: fix swizzle support for Vector3 and Vector4 in singles. The macro, which is enabled when preprocessing the headers for single-header libs, excluded the TypeForSize specializations, making these two not work with Math::gather() and Math::scatter(). It's done correctly in Vector2 and Color, not sure why not here.	4 months ago

Vladimír Vondruš	f297d593bf	Math: make all trivial mutable getters constexpr under C++14. Technically speaking there are many more opportunities to mark things as C++14 constexpr, such as various operators, but doing so would make them impossible to optimize with various (SIMD) intrisnics unless basically providing two separate implementations for them, one scalar, slow and constexpr and the other fast but not compile time, and dispatching with std::is_constant_evaluated() or some such from C++20. In other words, such functions cannot and will not be marked as constexpr in C++17 or older anyway, because the preference is and still should be runtime perf rather than doing excessive work at compile time, where it's hard to debug or reasonably test etc etc., and the more you rebuild the more you'll hate the cost of extra compile time caused by that.

Vladimír Vondruš	7eb520f77a	Underscore private MAGNUM_* macros to not leak into autocompletion. The MAGNUM_GL_ABSTRACTSHADERPROGRAM_SUBCLASS_DRAW_IMPLEMENTATION() and MAGNUM_GL_ABSTRACTSHADERPROGRAM_SUBCLASS_DISPATCH_IMPLEMENTATION() is documented so that one stays not underscored.	1 year ago

Vladimír Vondruš	60631459d9	Math: cross-link dot product and cross product docs.	2 years ago
Vladimír Vondruš	d5b5158869	Math: make const vector x/y/z/w and r/g/b/a accessors return const&. So they can be used in StridedArrayView member function slicing the same way as the mutable overloads. Pointer, Triple and other low-level containers do the same thing and this is one of the prime use cases for the slicing functionality, so it's silly it didn't actually work.	2 years ago
Vladimír Vondruš	22b846e2e8	Math: ability to construct vectors and matrices from sized arrays. Same as done for Containers::StaticArray some time ago. Since it's not a potentially dangerous operation, it's not made as an overload of the from() function, but instead a regular constructor. It's however kept explicit for now, even though it eventually might not need to be -- I'm not sure about potential consequences yet.	2 years ago
Vladimír Vondruš	70778ac307	Math: add typedefs for single-row matrices. May be useful for left-hand-side multiplication, as a counterpart for multiplying with (column) vectors from the right hand side.	2 years ago
Vladimír Vondruš	0aff2ec600	Math: make the external conversion SFINAE template arguments unnamed. It's like this in Corrade::Containers already, the reason it was still named here is probably just historical.	2 years ago
Vladimír Vondruš	279856f239	Math: allow creating a Vector from a BitVector. And document the more flexible alternative using lerp().	2 years ago
Vladimír Vondruš	2619dc33f1	doc: drop the redundant Magnum prefix from snippet files. I accidentally did that at first, and then "for consistency" continued with that for a decade.	2 years ago
Vladimír Vondruš	9cb623eaf9	Math: make MSVC 2015 correctly pick up the float*VectorNi operator. This complier is making my hair gray. Fortunately the out-of-class operator doesn't conflict with the in-class one, so it's purely an additive workaround. Adding extra checks to all subclasses to be sure this works correctly in all cases and not just in the base class.	2 years ago
Vladimír Vondruš	8b1026d457	Math: make all matrix and vector operators either member or friend. Except for a vector and a row matrix multiplication operator, which doesn't make sense to be a member. These are all now significantly shorter thanks to not having to repeat that many template parameters, and they can make use of direct access into the _data array for better debug perf.	2 years ago
Vladimír Vondruš	5e097681cb	Math: be reasonable, <utility> is not needed for std::declval. Despite what the standard tries to say. I bet a large portion of <type_traits> is impossible to implement without it, which is why all STL implementations define it there already.	3 years ago

Vladimír Vondruš	862c48517f	Math: add Vector2::{r,g}() and Vector3::rg(). For consistency with X/Y accessors. No reason to not have them.	3 years ago
Vladimír Vondruš	73c881f5ae	Math: mention that cross product can be used to calculate triangle area.	3 years ago
Vladimír Vondruš	9e796a9664	Math: clarify relation of distances and cross products. I spent a significant amount of time reinventing the wheel, i.e. figuring out how to use a cross product to calculate distance of a point to a line. Only to subseqently have a breakthrough discovery of Distance::linePoint() that actually does the same. The distance APIs and 2D and 3D cross-products are now linked together the math snippet is clarified, and both the 2D and 3D distance use the same equation, saving one unnecessary vector subtraction. The equivalence of the two equations is listed directly on that Wolfram link.	4 years ago

Vladimír Vondruš	1026aee80e	Moved the NoInit tag from Math to the root namespace. The old one is deprecated, and will be removed in a future release. Unfortunately, to avoid deprecation warnings, all use of NoInit in the Math library temporarily have to be Magnum::NoInit This will be cleaned up when the deprecated alias is removed.	6 years ago

Vladimír Vondruš	573125d0a9	Math: make cross() 10x faster in Debug. And the Vector3 version 5% slower in Release, on GCC at least. FFS, what was I thinking with the gather() things. Nice in user code, extremely bad in library code.	6 years ago
Vladimír Vondruš	73c37a8339	Add Vector[324][u][hsb] convenience typedefs for small types. And also Color variants, to make it complete. No half types for matrices right now, those might come later.	6 years ago

Vladimír Vondruš	05b1cefda5	Math: avoid operator[] calls where possible (and not too verbose). In debug builds (where nothing is inlined), this makes matrix multiplication run in 33% of the time and matrix inversion roughly twice as fast.	7 years ago
Vladimír Vondruš	64bc7f9c8e	Math: moved configuration value parsers to a dedicated header. There's a lot of string operations and that's nothing good to have included everywhere. Should speed up the compilation quite a bit.	7 years ago
