I am trying to make a digital asset which can generate a realistic wood grain texture.
For this, my first step was to make a irregular wave pattern which I can control with some parameters.
I thought I made it with the following codes:
f@leng = length(@P);
f@ang = acos(@P);
int seed = ch("seed");
f@deform = 1 + sin(@ang) * noise(@ang * seed);
@Cd = cos(@deform * @leng * $PI * chf("frequency"));
Then I found that my wave pattern is irregular but not perfectly irregular as they are symetrical to x axis.
I don't know what I did wrong.
Can anyone help me?
