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	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	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	90c5001673	Math: remove dead frustum/box intersection code. The additional corner checks are not implemented now, thus the code is more complex than it needs to be.	10 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	cfc622c92c	Math: explicitly instantiate commonly used Range debug operators. Might save some executable bloat. Not sure why this wasn't done already.	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
