Abstract

We review schemes for dividing cubic cells into simplices (tetrahedra) for interpolating from sampled data to R³, present visual and geometric artifacts generated in isosurfaces and volume renderings, and discuss how these artifacts relate to the filter kernels corresponding to the subdivision schemes.
