Your description is not very clear to me. If you described *exactly*
the plotting method that you thought about, we could help you implement
it in Mathematica.
This is one way for examining 3D scalar functions:
Manipulate[
ContourPlot3D[
x^2 + y^2 - z^2 == c, {x, -2, 2}, {y, -2, 2}, {z, -2, 2}],
{{c, 1}, 0, 3}]
(You might want to experiment with the option ContourStyle ->
Opacity[.5] too.)
Also, search for "volume visualization" or "volume rendering" on Google.
