Although implicit functions are extremely powerful in graphics, geometric design, and shape modeling, the full potential of implicit functions is yet to be fully realized due to the lack of flexible and interactive design techniques. In order to broaden the accessibility of implicit functions in geometric modeling, we marry the implicit solids, which are semi-algebraic sets of volumetric implicit functions, with the principle of physics-based models and formulate dynamic implicit solids. By using \"density springs\" to connect the scalar values of implicit functions, we offer a viable solution to introduce the elasticity into implicit representations. As a result, our dynamic implicit solids respond to sculpting forces in a natural and predictive manner. The geometric and physical behaviors are tightly coupled in our modeling system. The flexibility of our modeling technique allows users to easily modify the geometry and topology of sculpted objects, while the inherent physical properties can provide a natural interface for direct, force-based free-form deformation. The additional constraints provide users more control on the dynamic implicit solids. We have developed a sculpting system equipped with a large variety of physics-based toolkits and an intuitive haptic interface to facilitate the direct, natural editing of implicit functions in real-time. Our experiments demonstrate many attractive advantages of our dynamic approach for implicit modeling such as intuitive control, direct manipulation, real-time haptic feedback, and capability to model complicated geometry and arbitrary topology.","PeriodicalId":267347,"journal":{"name":"Proceedings SMI.

To develop the system we introduce new topological entities for effectively manipulating 2-manifold mesh structures. We identify a minimal set of fundamental operators, which is necessary and sufficient for performing all homeomorphic and topological operations on 2-manifold mesh structures. Extremely efficient algorithms are developed for the implementation of these operators. We also developed a set of powerful, user-friendly, and effective operators at the level of user interface. Users of our system can perform a large set of homeomorphic and topological changes with these user interface level operators. Our system is topologically robust in the sense that users will never create invalid 2-manifold mesh structure with these operators. In our system, the homeomorphic and topological surgery operations can be applied alternatively on 2-manifold meshes. With our system, users can blend surfaces, construct crusts and open holes on these crusts. With our system, the shapes that look like solid, non-manifold, or 2-manifold with boundary can be manipulated. The system also provides automatic texture mapping during topology changes.","PeriodicalId":267347,"journal":{"name":"Proceedings SMI.
