abstract = "We introduce a new mesh refinement method for subdivision
surfaces. It generates a semiregular 3-direction hierarchical
structure from control meshes representing 2D manifolds of
arbitrary topology. The main advantage of this structure is that
it allows the extraction of conforming variable-resolution meshes
based on spatially varying adaptation functions. We also present a
smoothing method designed to work in conjunction with our
semi-regular refinement. It produces generalized four direction
box spline surfaces of class C/sup 1/. Together the refinement and
smoothing operators result in a subdivision scheme that is very
effective in multiresolution applications.",
