                         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.",
