Hello there. If I am understanding you correctly, you wish to know the meaning of $\rho$, $\phi$, and $\theta$, yeah? $\rho$ is the radius that extends from the origin to a particular point on the edge of the spherical volumetric surface. $\theta$ is the angle extends from the positive x-axis to the projection of that point onto the xy-plane. $\phi$ is the angle that extends from the positive z-axis to the line of the radius of a particular point. I have attached an image for visualization.
