vector pos(float u,t){
        vector p = set(0,u,0);
        p+= u *0.2*curlnoise(p+0.1*t);
        return p;
        
    }
    
int npt = 30;
for (int i;i<npt;i++){

    float u = i/float(npt-1);
    vector p= pos(u,@Time);
    vector next_p = pos(u+0.1,@Time);

    }

int pts0[];
int pts1[];

for(int i;i<i@numpt;i++){


        vector p = point(0,"P",i);
        vector dir = point(0,"side",i);
        dir = normalize(dir);
        float u = float(i)/(@numpt-1);
        u = chramp("ramp",u);
        vector p0= p+dir*u;
        vector p1= p-dir *u;

        }
        
 for (int i;i<@numpt-1;i++){
 
 
        addprim(0,"poly",i,i+1,pts0[i+1],pts0[i]);
        addprim(0,"poly",pts1[i],pts1[i+1],i+1,i);
        }
