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	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	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	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	15e5bfa09e	Update credits and changelog, minor cleanup.	7 years ago
Marco Melorio	097289850a	Add toEuler() to Quaternion	7 years ago
Vladimír Vondruš	515637c76a	Math: implement a robust and faster Matrix4::normalMatrix(). This change makes the operations split into a bunch of separate functions, making the parts easier to document, however with a slight negative effect on debug performance: Starting Magnum::Math::Test::MatrixBenchmark with 16 test cases...

Vladimír Vondruš	e3a820f468	Math: benchmark basic Matrix operations. So I'm sure the next additions don't make things worse -- in the debug build, in particular.

Vladimír Vondruš	7f70dc7385	Math: XFAIL most (all?) NoInit tests in Release builds.	7 years ago
Vladimír Vondruš	17b3c8fac5	Math: support numeric indexing in gather() / scatter() as well.	7 years ago
Vladimír Vondruš	acc8d8994b	Math: added scatter(), renamed swizzle() to gather(). The swizzle() function is still present, only marked as deprecated and scheduled to be removed in some future release.	7 years ago
Vladimír Vondruš	4bc84f6815	Math: expand UnderlyingTypeOf to support vectors and matrices. This allows getting underlying type of those without needing to include them. Yay.	7 years ago
Vladimír Vondruš	1887fe0ab9	Math: added a scalar equal() / notEqual() variant.	7 years ago
Vladimír Vondruš	13b4bf8461	Math: use __builtin_sincos for sincos() on GCC. Makes this thing faster on Debug. But I'm not sure whether it's due to less function calls or this intrinsic being actually faster, heh. Probably a combination of both.	7 years ago
Vladimír Vondruš	a28e14491c	Math: verify that TypeTraits work correctly for signed infinities.	7 years ago
Vladimír Vondruš	3cf9dbf409	Math: added component-wise equal()/notEqual() for vectors.	7 years ago
Vladimír Vondruš	3d5f50ac49	Test: use the new setTestCaseTemplateName().	7 years ago
Vladimír Vondruš	a1cc0cb62d	Math: off-center Matrix4::perspectiveProjection().	7 years ago
Vladimír Vondruš	8e5ecfacac	Math: ignore NaNs also in Vector::min(), max() and minmax(). To have the API consistent.	7 years ago
Vladimír Vondruš	46fdb38cd2	Math: make batch min() / max() / minmax() ignore NaNs.	7 years ago
Vladimír Vondruš	d38303505d	Math: added batch isInf() and isNan().	7 years ago
Vladimír Vondruš	da43af403e	Math: minor cleanup and code simplification.	7 years ago
Vladimír Vondruš	28f12f9a5e	Math: improve the NaN propagation tests even more.	7 years ago
Vladimír Vondruš	75ffd39fe0	Math: make it possible to use Deg/Rad in all functions. This should have been here ages ago, haha.	7 years ago
Vladimír Vondruš	7941a769cd	Math: added IsUnitless type trait.	7 years ago
Vladimír Vondruš	19844352ff	Math: added UnderlyingTypeOf.	7 years ago
Vladimír Vondruš	aa2adb7222	Math: add IsScalar, IsVector, IsIntegral and IsFloatingPoint type traits. The standard ones are not good enough, so let's roll out my own.	7 years ago
Vladimír Vondruš	442d5576d0	Math: change the way BoolVector is printed to Debug. Found while working on the Python bindings --- BoolVector4(0b1010) got printed as BoolVector(0101), which is totally confusing. Now it prints it in a way that looks exactly the same as when constructing the vector with binary literals.	7 years ago
Vladimír Vondruš	4b6fabb004	Math: ability to Debug colors as actual colored squares.	7 years ago
Vladimír Vondruš	36ba5f4333	Math: ensure ZeroInit and IdentityInit constructors are explicit. Like NoInit ones. Not sure what I was doing there.	7 years ago
Vladimír Vondruš	3626562e1d	Adapted to Corrade changes. Mostly missing includes now.	7 years ago
Vladimír Vondruš	f8b9c69b16	Don't use std::tie() on std::pair(). It's nice and all, but including the whole <tuple> just for that is not worth it.	7 years ago
Vladimír Vondruš	8c1d62d97c	Math: use CORRADE_TARGET_EMSCRIPTEN instead of MAGNUM_TARGET_WEBGL. When WebGPU is here, what would we gonna do?	7 years ago
Vladimír Vondruš	754c84525e	The <cmath> header is not allowed anymore.	7 years ago
Vladimír Vondruš	0dd763fe9d	Math: fix deprecated build.	7 years ago
Vladimír Vondruš	53c1549e69	Math: deprecate Frustum::planes() in favor of begin()/end(). This allows us to get rid of the StaticArrayView, which is the last roadblock on the way to a single-header math. The planes() are now deprecated, along with the include, and will get removed in a future release.	7 years ago
Vladimír Vondruš	8079cda8aa	Math: check for OOB access in Frustum::operator[]().	7 years ago
Vladimír Vondruš	3a1713d549	Math: no need to include <tuple> just for std::tie() in tests. Unpack the pairs manually instead.	7 years ago
Vladimír Vondruš	c12680ec38	Math: move batch functionality to FunctionsBatch.h. Avoids including a (relatively) large ArrayView in Functions.h. Yes, we are now at a point where 500 lines matter.	7 years ago
Vladimír Vondruš	547a3f3cea	Math: use a dedicated type for HSV colors instead of a tuple. Pros: * faster compile times (#include <tuple> is 13k lines, ugh) * ability to have NoInit and ZeroInit constructors * ability to do fuzzy compare * named members, so we don't have to use mutable std::tie() Cons: * ... none? The old Color[34]::Hsv is still a tuple and the new ColorHsv is convertible to/from it (and even std::tie() works). These are all deprecated (along with the <tuple> include).	7 years ago
Vladimír Vondruš	e7af6bf07b	Math: minor cleanup and code shuffling.	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
Vladimír Vondruš	b24ffa4a3e	Use min() / max() / minmax() from Math instead of std::. First step to avoid the <algorithm> header.	7 years ago
Vladimír Vondruš	71c90e6024	Math: fix MSVC integer conversion warnings in a test.	7 years ago
Vladimír Vondruš	9a8e874eb4	Math: minor cleanup.	7 years ago
Vladimír Vondruš	5a010269bd	Math: implement component-wise bool operations on BoolVector.	7 years ago
