    We present a fast algorithm for converting quad meshes on the GPU to smooth surfaces. Meshes with 12,000 input quads, of which 60% have one or more non-4-valent vertices, are converted, evaluated and rendered with 9times9 resolution per quad at 50 frames per second. The conversion reproduces bi-cubic splines wherever possible and closely mimics the shape of the Catmull-Clark subdivision surface by... View full abstract»

    In this paper, we propose a manifold smoothing method based on the heat diffusion process. We start from the global equation of heat conservation and we decompose it into basic laws. The numerical scheme is derived in a straightforward way from the discretization of the basic heat transfer laws using computation algebraic topological tools CAT, thus providing a physical and topological explanation...

    In this paper, we introduce a parallel numerical scheme, the Lattice Boltzmann method, to shape modeling applications. The motivation of using this originally-designed fluid dynamics solver in surface modeling is its simplicity, locality, parallelism from the cellular-automata-originated updating rules, which can directly be mapped onto modern graphics hardware. A surface is implicitly represented... View full abstract»

  • Fairing wireframes in industrial surface design

    Publication Year: 2008, Page(s):29 - 35
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (907 KB) | HTML iconHTML

    Wireframe is a modeling tool widely used in industrial geometric design. The term wireframe refers to two sets of curves, with the property that each curve from one set intersects with each curve from the other set. Akin to the mu-, v-isocurves in a tensor-product surface, the two sets of curves in a wireframe span an underlying surface. In many industrial design activities, wireframes are usually...

  • Noise in 3D laser range scanner data

    This paper discusses noise in range data measured by a Konica Minolta Vivid 910 scanner. Previous papers considering denoising 3D mesh data have often used artificial data comprising Gaussian noise, which is independently distributed at each mesh point. Measurements of an accurately machined, almost planar test surface indicate that real scanner data does not have such properties. An initial chara... View full abstract»

    We present a fast deformation-based method for building time-varying surface models of dynamic objects from multiview video streams. Starting from an initial mesh representation, the surface of a dynamic object is tracked over time, both in geometry and connectivity, based on multiview silhouette information via a mesh-based deformation technique. The resulting smooth time-varying surface is then ... View full abstract»

  • Example based skeletonization using harmonic one-forms

    This paper presents a method to extract skeletons using examples. Our method is based on the observation that many deformations in real world applications are isometric or near isometric. By taking advantage of the intrinsic property of harmonic 1-form, i.e., it is determined by the metric and independent of the resolution and embedding, our method can easily find a consistent mapping between the ...

    Medical imaging has produced a large number of volumetric images capturing biological structures in 3D. Computer-based understanding of these structures can often benefit from the knowledge of shape components, particularly rod-like and plate-like parts, in such volumes. Previously, skeletons have been a common tool for identifying these shape components in a solid object. However, obtaining skele... View full abstract»
