Reaction: Marching cubes: A high resolution 3D surface construction algorithm

Nice diagram about the flow for medical algorithms and the comparison among CT, MRI, and SPECT. Cutting the model using boolean operations is a nice and easy way to manipulate the visual object.
The result says that execution time depend on the number of surfaces and resolution. It took 30 minutes for a 260x260x93 CT data. Just out of curiosity, how long would marching cube take with the current hardware environment?
Is there advantage (or disadvantage) looking up the precalculated table in this algorithm? For example, if the viewpoint changes, it needs to recalculate the table which may negatively affect when user interaction is involved. Even if the object rotates, the table needs to be modified, right?
