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	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	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	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	37565d5414	Math: print 8-bit colors as hex in Debug. So #ffffff00 instead of Vector(255, 255, 255, 0). Much shorter with the same information value.	10 years ago

Vladimír Vondruš	4a395ac490	Math: enlarge epsilon value for long doubles on MSVC. They are internally treated as 64-bit doubles, so there's no difference.	10 years ago
Vladimír Vondruš	cadd28276a	Math: conditionally include <algorithm> for std::max() in MSVC. Don't want to include it for every platform, as it is pretty huge...	10 years ago
Vladimír Vondruš	aef580ec62	Math: test iterative normalization of Complex/Quaternion transformations. If the values are renormalized after every step, it shouldn't happen that the value is denormalized even after calling `normalized()`. The test fails for DualQuaternion with large values, as expected. Will be fixed in the next commit.	10 years ago
Vladimír Vondruš	1dc1fc79b0	Math: better test cases for {*Complex,Quaternion}::isNormalized(). The expectation is that the values are considered normalized only if the difference is small enough. This should have been tested since the beginning, but instead this was waved away with a dumb test case testing obviously denormalized value and obviously normalized value. The test fails for DualQuaternion with large translation values (as expected). Will be fixed in following commits.	10 years ago
