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	4cf9459110	Math: return default-constructed value for min()/max() on empty range.	9 years ago
Vladimír Vondruš	bfa259fb18	Math: min() and max() for pointer ranges. The test is for the initializer list version, so it covers these as well.	9 years ago
Vladimír Vondruš	9e796b76c8	Math: added clamp(Vector, Vector, Vector), {min,max}(Vector, T) In order to provide consistent API with GLSL. Pretty annoying omission.	9 years ago
Vladimír Vondruš	59f69d2a4f	Math: assert that the (un)packed vector type has the same size.	9 years ago
Vladimír Vondruš	8637cbdc31	Math: Color4::{xyz,rgb}() should return Color3, not Vector3.	9 years ago

Vladimír Vondruš	9de8fb9a67	Math: expect minor sRGB monotonicity test failure on Emscripten -O3 build. The debug output isn't even able to print the difference as it is differing very little.	9 years ago
Vladimír Vondruš	5a0be1dfee	Math: document the test repeats to avoid confusion.	9 years ago

Vladimír Vondruš	bdb6daec82	Math: new Half literal class.	9 years ago
Vladimír Vondruš	16ef1ae0b6	Math: functions for half-float (un)packing. Most of the code is in the actual test where I'm comparing and benchmarking three different implementations (a naive/straightforward/ground-truth one, the chosen one and a fast though cache-spilling table-based one) to ensure the behavior is consistent across all of them and that the performance is within reasonable bounds. The Corrade::TestSuite benchmarking stuff needs serious improvements, though.	9 years ago
Vladimír Vondruš	c8cc1dc88e	Math: expect failure in SVD test only on non-optimized Emscripten builds. Emscripten 1.37.1 with -O3 doesn't fail there.	9 years ago
Vladimír Vondruš	9ebc1068cb	Math: missing include after updates in Corrade::TestSuite.	9 years ago
Vladimír Vondruš	502d59c2a8	Math: ability to specify number of integer bits for {un,}pack(). This also allowed me to get rid of the <limits> header.	9 years ago
Vladimír Vondruš	996c707cbc	Math: reduced code duplication in vector packing functions. This should also improve debug performance as there is less code to inline.	9 years ago
Vladimír Vondruš	54c7b8d775	Math: document why unpacking is done this way.	9 years ago
Vladimír Vondruš	e5fe46949e	Math: got rid of <limits> dependency in Constants.h. The tests still pass, so why not.	9 years ago
Vladimír Vondruš	6944818cc6	Math: improved packing test with in-range values to verify rounding.	9 years ago
Vladimír Vondruš	dd2058cee3	Math: renamed {de,}normalize() to {,un}pack() in a new Packing.h header. To be more consistent with GLSL naming. Also, the original naming was quite misleading, as normalize() is used in GLSL for something completely different. If building with deprecated APIs, the Functions.h header includes the new Packing.h header and the {de,}normalize() functions are defined as deprecated aliases to the new functions. This will be removed at some point in the future.	9 years ago
Vladimír Vondruš	543782d78b	Math: added Algorithms::kahanSum(). The test is running pretty slow on debug builds, though (sorry). I see no way how to make it faster while still exposing the issues with std::accumulate().	9 years ago
Vladimír Vondruš	ce050888fd	Math: function to convert RGB to XYZ color space. Building blocks for supporting other colorspaces such as Lab. I was not happy with matrices from Wikipedia because they don't round-trip perfectly so I have slightly different / more precise versions that do round-trip.	10 years ago
Vladimír Vondruš	2b97e53360	Math: sRGB support in Color classes. At first I designed a hugely disrupting change that basically deprecated everything related to 8-bit linear RGB colors, but then I took a step back and reconsidered 8-bit linear RGB as a valid use case. The documentation of Color classes, typedefs and literals was clarified to mention that these classes should always represent linear RGB and that 8-bit colors are commonly treated as not linear and one should be aware of it. There is now a new Color3::fromSrgb() and Color3::toSrgb() that converts from sRGB representation to a linear RGB usable for calculations and then back. For four-component colors, there is now Color4::fromSrgbAlpha() and Color4::toSrgbAlpha(). Similarly to what OpenGL sRGB behavior is regarding to alpha, the alpha channel is kept linear, that's why I'm also calling it sRGB + alpha instead of sRGBA. Besides that, there are four new literals _srgb, _srgba, _srgbf and _srgbaf that have different semantics to support the sRGB workflow. The 8-bit versions are equivalent to _rgb and _rgba, though they don't return Color3 but a non-color Vector3 to hint that the result is not a linear RGB color. Main purpose of these is documentation. The float versions apply an inverse sRGB curve to the input, returning a linear RGB color.	10 years ago

Vladimír Vondruš	41aaf1321f	Math: construct fully-overwritten outputs in functions with NoInit. Slightly faster on non-optimized builds (I would assume the optimizer does this anyway).	10 years ago
Vladimír Vondruš	8e576d9c73	Math: improved HSV color tests. Testing both RGB and RGBA implementation for both floating-point and integral types.	10 years ago

Vladimír Vondruš	ccb85ec65b	Math: pass largish things as const references instead of a copy.	10 years ago
Vladimír Vondruš	c27a12bb30	Math: renamed Color[34]::HSV types and functions to Color[34]::Hsv. For consistency with naming scheme for other color spaces (upcoming Srgb, Xyz, Lab etc.). The old uppercase names are now marked as deprecated and will be removed in some future release.	10 years ago

Vladimír Vondruš	d2eae35966	Math: these functions are not constexpr.	10 years ago
Vladimír Vondruš	a8d1fc4d84	Math: work around constexpr issues on old GCCs in Frustum test. Travis CI GCC 4.7 and Android NDK GCC 4.9 fail to compile that. GCC 6 works, not sure about GCC 5.	10 years ago
Vladimír Vondruš	e75bef1d53	Math: MSVC 2015 workarounds for constexpr in Frustum tests.	10 years ago
Vladimír Vondruš	7f89105a51	Math: converted Geometry::Distance and Intersection to namespaces. No need for them to be classes, less indentation, less keywords and boilerplate, more space for documentation, better `using` usage. Also revised and fixed various issues in the documentation.	10 years ago

Vladimír Vondruš	421218c2d1	Math: return const& from Frustum::operator[]. So constexpr access on Vector elements is possible as well.	10 years ago
Vladimír Vondruš	20b3adbc55	Math: ability to convert Bezier from/to external representation.	10 years ago
