public double encode (double val)
Convert val to its gamma encoded value.
For a linear value L in the range [0..1], conversion to the non-linear (gamma encoded) L' is in general performed with a power function like:
L' = L ^ (1 / gamma)Depending on func, different formulas might be applied. Some formulas encode a linear segment in the lower range.
