It seems there isn't a function in sagemath which can plot contours of a function $f(x, y, z)$ as transparent layers in 3d space like in mayavi.

Is there an alternate way to achieve the same effect in sage?

You might be able to get implicit_plot3d to do it. Maybe something like the following would work for you.

var('x,y,z')
f(x,y,z)=x^2+y^2+z^2/4
p=Graphics()
for k in [1,2,3,4]:
    p+=implicit_plot3d(f(x,y,z)==k,(x,-2,2),(y,-2,2),(z,-5,5),opacity=0.4)
p

I usually use something similar for level surfaces. Note that with the upcoming Jmol upgrade you can plot them first, and adjust their color and opacity to your liking interactively later.
