abstract = "In this work we address the problem of computing point-based
surface approximations from point clouds. Our approach is based on
recently presented methods that define the approximated surface as
the set of stationary points for an operator that projects points
in the space onto the surface. We present a novel projection
operator that differs from the defined in previous work in that it
uses principal curvatures and directions approximation and an
anisotropic diffusion equation to ensure an accurate approximation
to the surface. We show how to estimate the principal curvatures
and directions for point clouds and discuss the usefulness of the
curvature information in the context of point-based surface
modeling and rendering.",
