rgb <-> oklab to/from convert, color blend through oklab space
// This gist contains JavaScript functions and tests for:
// - conversion from gamma-corrected (or gamma-compressed) sRGB to linear RGB, to Oklab
// - interpolation through Oklab
// - conversion back to linear RGB, then sRGB
// To use these tests, install nodejs, save this file locally, and run with:
// node OklabExperiments.js
// No other dependencies are required to use this.
// Thanks to some helpful folks in the generative art community for helping me better understand what's happening with this.

One way to solve the glibc compatibility problem. In my case, when building a program with libthrift.a on linux with glibc version 2.15, ld always links memcpy@GLIBC_2.14 which cannot be found on systems with glibc version < 2.14. So, use this file to define a symbol __wrap_memcpy and use -Wl,--wrap=memcpy to tell ld using this symbol when meeti…
#include <string.h>
void *__memcpy_glibc_2_2_5(void *, const void *, size_t);
asm(".symver __memcpy_glibc_2_2_5, memcpy@GLIBC_2.2.5");
void *__wrap_memcpy(void *dest, const void *src, size_t n)
{
return __memcpy_glibc_2_2_5(dest, src, n);
}
