WebNote that 'linear' in this sense is that a certain 'x' value is mapped to the same 'y' value. It means it forms a "straight line graph." That 'linear' has no relation to the data type used to represent the colour value -- whether it's represented by a normalised floating point value (0.0 ~ 1.0) or by an unsigned byte value (0 ~ 255).

WebIt’s apparent that the sRGB inventors selected the second of these points, and rounded its value to 4 significant digits to get 0.04045. They then used that rounded sRGB value to recalculate the Linear value, and got 0.00313080. I don’t know why their Linear value has more significant digits (5 or 6) than their sRGB value (4). WebExample 24-1. Manually Converting Color Values to a Linear Space. Texture lookups can apply inverse gamma correction so that the rest of your shader is working with linear values. However, using an sRGB texture is faster, allows proper linear texture filtering (GeForce 8 and later), and requires no extra shader code.
