Abstract :
Two new approaches for approximating normals for volume visualization by marching cubes isosurfacing are introduced. The approaches utilize higher order approximations than the standard approach of simple central differencing gradients. The impact of the new approximation approaches on isosurface renderings are also considered by quantitative pixel-level comparisons on scenes for which optimal renderings are known.
