Shape Recovery Using Dynamic Subdivision Surfaces
نویسندگان
چکیده
A new dynamic subdivision surface model is pro posed for shape recovery from D data sets The model inherits the attractive properties of the Catmull Clark subdivision scheme and is set in a physics based mod eling paradigm Unlike other existing methods our model does not require a parameterized input mesh to recover shapes of arbitrary topology allows direct ma nipulation of the limit surface via application of forces and provides a fast robust and hierarchical approach to recover complex shapes from D data with very few degrees of freedom control vertices We provide an analytic formulation and introduce the physical quan tities required to develop the dynamic subdivision sur face model which can be deformed by applying forces synthesized from the data Our experiments demon strate that this new dynamic model has a promising future in shape recovery from volume and range data sets

Procedural Shape Synthesis on Subdivision Surfaces
We present methods for synthesizing 3D shape features on subdivision surfaces using multiscale procedural techniques. Multiscale synthesis is a powerful approach for creating surfaces with different levels of detail. Our methods can also blend multiple example multiresolution surfaces, including procedurally-defined surfaces as well as captured models.
متن کاملDynamic Catmull-Clark Subdivision Surfaces
Recursive subdivision schemes have been extensively used in computer graphics, computer-aided geometric design, and scientific visualization for modeling smooth surfaces of arbitrary topology. Recursive subdivision generates a visually pleasing smooth surface in the limit from an initial user-specified polygonal mesh through the repeated application of a fixed set of subdivision rules. In this ...

متن کاملFlexible Adaptive Tesselation of Subdivision Surfaces
Subdivision surfaces are a popular representation for the freeform shape in geometric modeling. While the subdivision process rapidly converges to a smooth shape, computing and rendering all the vertices is too expensive in the sense of the memory consumption and run time, and also superfluous. Our work was inspired by a demand for a rendering of dynamic scenes and an interactive rendering of t...
