3d parametric spiral to 3D goldean mean spiral

Question

I know I can create a 3d parametric spiral with the formula below but How can I do the same thing with goldean spiral?
I looked at https://en.wikipedia.org/wiki/Golden_spiral but I don't see how to convert that formula on the page into a 3D parametric curve.

x=t *sin(t);
y=t *cos(t);
z=t;

Thanks to Narasimham I got it to work some what. But does anyone know why it doesn't reach the zero axis? I circled the point A which is the x,y,z coordinates in yellow and it shows up as x=1,y=0,z=1. How can I get this to be x=0, y=0, z=0. See image below in yellow.

Answer 1

Depends on sign of $b$. Choosing $ b<0, t \rightarrow \infty$, radius $ \rightarrow 0$
