View dependent isosurface extraction

: We present a dynamic view-dependent isosurface extraction method. Our approach is based on the 3-stage approach we first suggested in WISE [15], i.e., front-to-back traversal, software pruning based on visibility and final rendering using the graphics hardware. In this work we re-examine the WISE method and similar view-dependent extraction methods, and propose modifications that accelerate the extraction time by a factor of 5 to 10. In particular we suggest using a bottom-up approach for rendering occluding triangles, replacing the traditional marching cubes triangulation with triangle fans and using point-based rendering for sub-pixel sections of the isosurface.
