# Using Manipulate to make a 3D plot of a function of three variables [closed]

I have a function $S = S(\alpha,\tau,q)$. I am interested in plotting a 3DPlot of $S(q,\tau)$ for a given value of $\alpha$. However, I would like to visualize this by manipulating $\alpha$ with the Manipulate command in Mathematica.

I can't really figure out how to paste the Mathematica code that I am currently trying but one thing I should note is that the range of values for plotting also depends on the variable being manipulated.

Can anyone point me in the right direction?
