GitHub - TrianglesPCT/srgb: SRGB conversion routines designed to be easy to vectorize by only using instructions trivially available with SSE/AVX(avoids pow etc). These are the C++ reference implementations. They are accurate enough to support 8 bit srgb -> 32bit float linear -> 8 bit srgb and produce the original value. The SIMD variants can also use the 11 bit rcp instructions, as we really do not need full 32 bit float precision here. //The SIMD code is not provided because it uses my own SSE/AVX library which is too large and complex for someone just wanting some srgb conversion. //THis code should be auto vectorizable on a not shitty auto vectorizer. //MSVC is shitty so don't expect it to auto vectorize this, it is too stupid to handle the conditional despite this being a trivial VBLEND
