Abstract :
We review several schemes for dividing cubical cells into simplices (tetrahedra) in 3-D for interpolating from sampled data to R 3 or for computing isosurfaces by barycentric interpolation. We present test data that reveal the geometric artifacts that these subdivision schemes generate, and discuss how these artifacts relate to the filter kernels that correspond to the subdivision schemes.
