Infinite animation

[plazadelmar]

I would like to use sin, cos, or tan to create infinite animation looking like 8. Does someone know how to set it up in expressions or VOP or vex?

int prim = addprim(0,"polyline");
float u;
int npt = chi("npt");
    for (int i;i<npt;i++){
    u = 6.28*float(i)/(npt-1);
    
    vector pos = set(cos(@Time+u),sin(@Time+u),
    sin((u+@Time)*2));
    addvertex(0,prim,addpoint(0,pos));
    
    }
