sRGB to Linear Converter

sRGB


Linear


Formulas:

sRGB =
if (Linear < 0.0031308) Linear * 12.92
else (1.055 * pow(Linear, 0.41666) - 0.055)

Linear =
if (sRGB < 0.04045) sRGB * 0.0773993808
else (pow(sRGB * 0.9478672986 + 0.0521327014, 2.4))

Specular/IOR Converter

Specular


Index of Refraction


Formulas:

Specular = pow((IOR - 1) / (IOR + 1), 2) / 0.08

IOR = 1 / (2 / (sqrt(0.08 * Specular) + 1) - 1)
