    Hello, I am trying to recreate a shape shown in the attached photo, from the attached article
    I have tried to create this shape in MATLAB as shown in the code bellow ,
    from this formula i get a 2D shape and not the shown 3D shape , how to create this 3D shape?
    Thanks


    theta_0=15;
    alpha=60;
    delta=90;
    r0=2.3;
    D=15.2;
    a=sin(theta_0)/(tan(alpha));
    r1=r0*exp(a*phi);

    r1=r0*exp(a*phi-pi)
