Abstract: |

In
this paper we propose a new modeling paradigm for local and global
editing on point set surfaces. The proposed technique unifies
the topological advantage of implicitly defined surfaces, the
strength of physics-based modeling techniques, and the simplicity
of point-sampled surfaces. The implicit representation not only
affords powerful local surface sculpting and global freeform deformation,
but also enables users to modify the topology of the sculpted
point-set easily. We have developed a variety of editing toolkits
that can dynamically manipulate the implicitly defined point-set
surface and perform global and local free-form deformations, interactive
sketching, embossing, and smoothing easily. Our experiments demonstrate
that the proposed methodology augments the current point set based
modeling techniques with the new and powerful editing scheme. |
