One option is several implicit plots, colored by value, i.e. something
like:
var('x,y,z')
f=cos(x)*cos(y)+cos(y)*cos(z)+cos(z)*cos(x)
imps = []
plot_range = srange(0,3,.75)
color_range = [i/N(len(plot_range)) for i in range(len(plot_range))]
for i,q in enumerate(plot_range):
red = color_range[i]
imps.append(implicit_plot3d(f-q==0, (x, -2, 2), (y, -2, 2), (z,
-2, 2), opacity = .5, rgbcolor = (red,0,1-red)))
show(sum(imps))
