No no...
Make a fully procedural wood texture is interesting to me. It is keep my
attention these days.

I solved color-map cycling by creating main part of pigment (using function) ,
such function change its value from 0~1~0 every year. It has been done, so I
don't concern it anymore.

"The domain of user generated function" means I needs provide something flexible
for user to apply their own function. Before that time I can offer the standard
function which I developed.

How do you get such black spalting?

I will add knots in my output pigment pattern when I prepare enough code. But
they are just pattern, not a 3D shape.
