onoise on copied lines

[logix1390]

Hello,

I have a bunch of lines copied to points.

I make a ramp based on the curveu then apply the onoise function after I copied the lines

It works fine, just that when i increase my noise really high, it seems like the geometry travels in a particular direction and not truly randomized.

 

I apply this wrangle after i copy the lines

int turb=chi("Turb");
float rough=ch("rough");
float atten= ch("atten");

@P+= onoise(@P,turb,rough,atten)*@Cd.x;

 

I looked up the onoise function in the help files, and i have followed it directly. Maybe I am missing somthing else?

I will attach my file for anyone that wants to take a look

Thank you

*@Cd.x is the problem, it converts your 3D noise into 1D noise
you can add an explicit vector casting: *vector(@Cd.x)
// I also added some parameters for: frequency/offset/amplitude 

@P+= vector(onoise(@P*chf("freq")+chv("offset"),chi("turb"),ch("rough"),ch("atten")))*vector(@Cd.x)*chf("amp");

Ahh makes sense.. Thank you bunker!
