How to plot a function of 3 variables and show a slice in the same plot?

Hi I have a function f dependent on 3 variables x,y,z. I want to plot f and also show a slice of f for a particular value of x,y,z in the same plot of f. For example let

x = -10:0.1:10; 
y = -10:0.1:10; 
z = -10:0.1:10; 
f = x^2 + 3y^2 + exp(z);

How can i do this? Please help me out.

Hi

Thank You, Is there a direct function to plot f? What I want is a surface plot. But how do I use it for f?

Thanks
