Table 1: Timings for single processor isosurface extraction of two data sets, using Marching Cubes, edge-hashing, and cache-ring algorithms.
Table 1 contains timing results from running the three isosurfacing methods on the smaller MRI data sets, using only a single CPU. The edge-hash and cache-ring build both a geometric and a topological surface, and so we have included timings for the ``Overhead'' of allocating and copying the topological surface. This permits a more consistent comparison between these methods and the Marching Cubes methods.
