Vladimír Vondruš	50e21015eb	Math: make it possible to construct Half from a double. A lot of generic code uses T(1.0) and right now that caused an ambiguity between the Float and UnsignedShort constructors.	6 years ago
Vladimír Vondruš	10dd468eca	Math: minimal support for Half in TypeTraits.	6 years ago
Vladimír Vondruš	3734568cdf	Math: switch to our type traits in Color internals. In preparation for having the Half type usable in Color.	6 years ago
Vladimír Vondruš	f5a5e10c50	Math: batch table-based half-float packing/unpacking. It's a lot of code, but it still seems to be the fastest option of all we have. This was the original idea when implementing half-float support in 2016 but then I shelved it in favor of a simpler (but slower) code, keeping the table only for the benchmark, calculated at runtime. But now we need a batch version of this, so this comes handy.	6 years ago
Vladimír Vondruš	69e370c4c7	GCC 4.8, happy to see you're still around, causing problems.	6 years ago
Vladimír Vondruš	88fabb1ef6	Math: reduce header dependencies a bit.	6 years ago
Vladimír Vondruš	daf471381e	Math: add batch integer packing/unpacking and casting functions. To be used for conversion of the upcoming mesh attribute types.	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	c85b537937	Revert "Math: preserve signs in the Matrix[34]::scaling() getter." Turns out this seriously broke properites that should always hold, such as that RS = M for a R and S extracted out of M. Another way to fix this would be flipping signs in the rotation() / rotationShear() / ... queries as well, but that adds extra operations to both rotation() and scaling() and at that point it's just better to do what was done the whole decade before. To ensure this doesn't happen again and doesn't cost me a whole day of debugging in an end-user app (SceneGraph TRS transformations got broken because those assume that rotation() and scaling() do* combine back, which is a reasonable thing to assume), the docs are extended to note this and there's an explicit test for both negative scale and large angle corner cases as well. This reverts commit `9aa68715db`.	6 years ago
Vladimír Vondruš	a2118730a3	Math: fix a warning on 32bit MSVC.	6 years ago
Nghia Truong	1ef813fdad	Math: add reflect() and refract() functions. Co-authored-by: Vladimír Vondruš <mosra@centrum.cz>	6 years ago
Vladimír Vondruš	b2328f57cd	Math: fall back to lerp when slerp'd quaternions are too close. Returning just the first argument had several issues, one of them was causing iterative interpolations to get stuck at the initial position forever.	6 years ago
Vladimír Vondruš	c4a3b273e6	Math: provide transformVector() also on the DualThing classes. To make them more consistent with Matrix3/4, making switching from one to the other easier.	6 years ago
Vladimír Vondruš	ea92c5b36f	Math: clarify that implicit conversion of Foo to a DualFoo is rotation. Had to remind myself about that.	6 years ago
Vladimír Vondruš	4490dfd68f	Math: use a degree symbol for hue ranges.	6 years ago
Vladimír Vondruš	bc99e6fa57	Math: improve docs for color (un)packing and sRGB conversion.	6 years ago
Vladimír Vondruš	73f776193d	Math: constexpr is inline.	6 years ago
Vladimír Vondruš	43f5f06956	Math: avoid warnings when calling length() on an integer Vector. Also update the docs to hint the result may be imprecise on integer types, and suggest Manhattan length as well.	6 years ago
Vladimír Vondruš	92b1cdf6b7	Math: pass strided array views by const&. It has the size of three pointers, which is more than a little. Unfortunately doing just that causes infinite recursion, so be a little more specific when delegating from the overloads.	6 years ago
Vladimír Vondruš	a6dd63af0f	Math: make batch functions actually usable. No longer it's needed to add ugly explicit template types or casts.	6 years ago
Vladimír Vondruš	742dc406fd	Math: don't include FunctionsBatch.h from Functions.h anymore. These two got split in 2019.10 but one included the other for backwards compat. It makes everything suffer from worse compile times, so not doing that anymore.	6 years ago
Vladimír Vondruš	d69b6f8c40	Math: test and fix array-taking isInf()/isNan() also with vectors. Next time I need to test properly.	6 years ago
Vladimír Vondruš	71b775aeb1	Math: minor test cleanup.	6 years ago
Vladimír Vondruš	d4f7c853ae	Math: make Constants::inf() work with clang-cl 8. Using a similar workaround as for nan(). It works with version 9 tho.	6 years ago
Vladimír Vondruš	3b940f2509	doc: avoid referencing the deprecated Math::swizzle() function.	6 years ago
Vladimír Vondruš	9aa68715db	Math: preserve signs in the Matrix[34]::scaling() getter. This is a breaking change, but I think it is worth doing. Because now Matrix4::scaling(vec).scaling() == vec which was true also for translation and other.	6 years ago

Vladimír Vondruš	a920722839	doc: label deprecated APIs and stuff new since 2019.10 with version info. Should make new things more discoverable, avoid confusion when a documented API isn't there and reduce the need for maintaining multiple separate versions of the docs.	7 years ago
Vladimír Vondruš	de3f8858f0	Math: now that we have a standalone cofactor(), inline its internals. Apparently this gives a nearly three-times speed up compared to before. Didn't expect that.
