Isosurface evaluation without introducing any smoothing

Hi to everybody,
I've noticed with some simple tutorial example that the isosurface function introduces some kind of smoothing in my matrix before starting the calculation of the isosurface. For my purposes this is very problematic, I rather prefer to see a surface divided in several disconnected pieces than a compact and smooth one. Is there one different algorithm that evaluates isosurfaces without introducing any kind of smoothing? Do anyone knows how may i solve my problem?
Thanks in advance to anyone answering,
Fabio

An isosurface has to interpolate by nature in order to calculate triangles.
What are you trying to do? You might be able to call patch directly if you are just looking for a visualization.

Then perhaps the simplest method would be to come up with a better "isovalue" development algorithm. I.e. rather than fighting with isosurface work on making the values of your 3d matrix more distinct so that the isovalue threshold has more meaning...
