Reproduce noise pattern via manipulating UVs

[akirasun]

Hey guys
I'm trying to reproduce same noise pattern which originally created by blender.

In original video(@00:01:40), author used Mapping node to manipulate UVs.

 

 

In houdini, I tried UV Position VOP node but unfortunately can't get reasonable result.

Thanks for any help

Cheers

Grid, Noise ,bbox(0, D_XSIZE),Copy Sop, than

//on prim
vector min, max;
getbbox(min, max);
v@min = min;
v@max = max;

 

vector min = prim(geoself(), "min", 0);
 vector max = prim(geoself(), "max", 0);
 
 float height = chf("height");
 float radius = chf("radius");
 float rMin = radius;
 float rMax = radius + height;
 float r = fit(@P.y, min.y, max.y, rMin, rMax);
 

 float radianMin = 0.0;
 float radianMax = 2.0 * $PI;
 float radian = fit(@P.x, max.x, min.x, radianMin, radianMax);
 

 float x = r * cos(radian);
 float y = r * sin(radian);
 float z = 0;
 @P = set(x, y, z);
