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
Vladimír Vondruš	e75c7639e7	Math: test Matrix[34]::scalingSquared().	7 years ago
Vladimír Vondruš	2b08995c24	Math: after the pack() fix, some Android issues are no more. Yay!	7 years ago
Vladimír Vondruš	38573c7a82	Math: we're not signing here, no.	7 years ago
Vladimír Vondruš	e62ce4faa6	Math: fix pack() to correctly select the nearest integral value. Together with an assorted set of off-by-one changes to tests involving packing, in addition to the changes done in the previous test cleanup commit. Now Color3 sRGB conversion rountrips correctly.	7 years ago
Vladimír Vondruš	a87c7805f4	Math: rework sRGB, XYZ and packing tests with emphasis on rountripping. Makes them quite simpler. Doesn't pass for the sRGB roundtrip. Who would have thought.	7 years ago
Vladimír Vondruš	9c35b11521	Math: fix unused function warning on Emscripten.	7 years ago
Vladimír Vondruš	2149f7b869	Wrap all tests in unnamed namespaces. This makes the compiler warn about test cases that aren't ever used, which is a good thing.	7 years ago
Vladimír Vondruš	e6b7aa12fa	Updated copyright year.	7 years ago
Vladimír Vondruš	3e3eb21181	Math: correct order for test implementations.	8 years ago
Vladimír Vondruš	f5b90cefba	Math: whoops, forgot about StrictWeakOrdering for Frustum. Just a stretched version of the test for Matrix4. Hope that's okay.	8 years ago
