Adaptive and Quality Quadrilateral/Hexahedral Meshing from Volumetric Data.
This paper describes an algorithm to extract adaptive and quality quadrilateral/hexahedral meshes directly from volumetric data. First, a bottom-up surface topology preserving octree-based algorithm is applied to select a starting octree level. Then the dual contouring method is used to extract a preliminary uniform quad/hex mesh, which is decomposed into finer quads/hexes adaptively without in...

متن کاملAdaptive Multiresolution and Quality 3D Meshing from Imaging Data
This paper presents an algorithm to extract adaptive and quality 3D meshes directly from volumetric imaging data primarily Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). The extracted tetrahedral and hexahedral meshes are extensively used in the Finite Element Method (FEM). Our comprehensive approach combines bilateral and anisotropic (feature specific) diffusion filtering, with...
