Vladimír Vondruš	f43fa6ff95	Math: add APIs for quaternion reflection. It isn't really useful for anything in practice, but I'm putting it there for learning purposes because the topic comes up every now and then.	3 years ago
Vladimír Vondruš	be9a3c247d	Math: change all assertions to debug-only. The perf cost is just too great for these to be enabled always. The only place where the assertions are kept always is in the batch APIs -- there it's assumed the function is called on large enough data to offset this overhead, plus since it's often dealing with large blocks of data the memory safety is more important than various FP drifts which were the usual case why other assertions were firing.	3 years ago
Vladimír Vondruš	dfe37f61d1	Math: redo Matrix4::normalMatrix() as an inverse transpose. The article this API was originally based on assumes a scenario which just isn't matching usual practices here, giving wrong results. Too bad I didn't spend more time questioning the proof there and just blindly assumed it's correct because everyone said so. Won't be typing all that reasoning again in the commit message, see the changelog entry and the comment in the test for details.	3 years ago

Vladimír Vondruš	ff1b0ab307	Math: add off-center variants of 2D/3D orthographic projection as well. Was just perspective projection right now.	5 years ago
Vladimír Vondruš	3697125c7d	Math: disallow reflections in {Complex,Quaternion}::fromMatrix(). And update docs in Matrix[34]::rotation() and related functions to note this. This is a breaking change that may cause existing code to start asserting.	5 years ago
Vladimír Vondruš	3097c4c1f0	Math: class-level documentation for Matrix3 and Matrix4. Another one that was long on my TODO list.	5 years ago
Vladimír Vondruš	7072befbdb	Math: generalize slicing and expanding to arbitrarily-sized matrices. Originally was done only for square matrices, but now I need that for converting 3x3 -> 3x4 and back (UBO packing, ugh ugh), so let's generalize.	5 years ago

Vladimír Vondruš	34a52e48ed	Math: link to the corresponding classic GL/GLU functions. I was porting some PyOpenGL code and knowing how the ancient GL API maps to Magnum helped tremendously.	5 years ago
Squareys	f69f3393ec	Math: Add DualQuaternion/DualComplex::from(rotation, translation) Signed-off-by: Squareys <squareys@googlemail.com>	6 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	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
Nghia Truong	1ef813fdad	Math: add reflect() and refract() functions. Co-authored-by: Vladimír Vondruš <mosra@centrum.cz>	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	6fbedd8f52	Revert "doc: pile on more Doxygen workarounds." This reverts commit `0b7831c1ad`.	6 years ago
Vladimír Vondruš	0b7831c1ad	doc: pile on more Doxygen workarounds. Sad! https://github.com/doxygen/doxygen/issues/7472	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	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	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	fbd3dedeb3	Math: add Matrix[34]::rotationShear(), scalingSquared() and scaling(). Important: the rotation() accessor now allows non-uniform scaling but expects orthogonality (previously it allowed non-orthogonal rotation axes but disallowed non-uniform scaling). Documentation of all these accessors is further improved now as well.	8 years ago

Vladimír Vondruš	aa69bbcc19	Math: ability to create matrices with one value for all components. In order to do that with the previous API, one had to write an abomination like auto a = Matrix4x4::fromVector(Math::Vector<16, Float>{0.5f}); Ugh.	9 years ago
Vladimír Vondruš	6e10b2e205	Math: doc++ The TODOs were removed and put into GitHub projects to be a bit more visible to random strangers.	9 years ago
Vladimír Vondruš	28c31bfc96	Math: I don't see why we should have those overloads. The compiler does that for us. Probably a brain fart from 2010. On the other hand, the ConfigurationValue specializations need to be there, because the type is used explicitly as template parameter.	10 years ago
Vladimír Vondruš	5fcdd48808	Math: clarify what Matrix4::lookAt() does.	10 years ago
