Deformable Smooth Surface Design
A new paradigm for designing smooth surfaces is described. A finite set of points with weights specifies a closed surface in space referred to as skin. It consists of one or more components, each tangent continuous and free of self-intersections and intersections with other components. The skin varies continuously with the weights and locations of the points, and the variation includes the poss...
متن کاملApproximating Polygonal Objects by Deformable Smooth Surfaces
We propose a method to approximate a polygonal object by a deformable smooth surface, namely the t-skin defined by Edelsbrunner [5] for all 0 < t < 1. We guarantee that they are homeomorphic and their Hausdorff distance is at most > 0. This construction make it possible for fully automatic, smooth and robust deformation between two polygonal objects with different topologies. En route to our re...
متن کاملApproximating polyhedral objects with deformable smooth surfaces
We propose a method to approximate a polyhedral object with a deformable smooth surface, namely the t-skin defined by Edelsbrunner for all 0 < t < 1. We guarantee that they are homeomorphic and their Hausdorff distance is at most ε > 0. This construction makes it possible for fully automatic, smooth and robust deformation between two polyhedral objects with different topologies. En route to our...
متن کاملSLIME: A new deformable surface
Deformable surfaces have many applications in surface reconstruction, tracking and segmentation of range or volumetric data. Many existing deformable surfaces connect control points in a predefined and inflexible way. This means that the surface topology is fixed in advance, and also imposes severe limitations on how a surface can be described. For example a rectangular grid of control points c...
متن کاملDeformable Surface Matching for Statistical Shape Analysis
We propose a deformable surface model for matching anatomically homologous points for a specific region of interest (ROI), based on both surrounding intensity structures and shape characteristics. The initial estimate of the deformable mesh for the individual ROI was derived by transforming the template mesh to the individual image space using nonlinear warping. For the deformable surface model...
