If you have a dense enough sampling you could use the scatteredInterpolant to get interpolated values at a regular grid and then you could use slice to display selected cuts through your volume. This is what you'd do if you have some "intensity"-data sampled at x,y,z if you want to display surfaces for sub-sets of x,y,z-data you might look at trisurf. So have a look at the help and documentation of those functions.
