Adaptive Curvature-Sensitive Meshing of the Medial Axis
نویسندگان
چکیده
The medial axis transform provides an alternative r epresentation of geometric models that has many use ful properties for analysis modelling. Applications include decomposition of ge neral solids into sub regions for mapped meshing, i dentification of slender regions for dimensional reduction and recognition o f small features for suppression. In order to serve these purposes effectively, it is important to approximate the medial axis so that the curvatur e has been respected. This paper describes a genera l idea, which is based on equal distance criteria, for adaptive, curvature-sensitive mesh refinement on the medial a xis, after its topology has been defined. The completed set of theories and exa mples for 2-D planar objects and 3-D solid objects are presented.

LayTracks: a new approach to automated geometry adaptive quadrilateral mesh generation using medial axis transform
A new mesh generation algorithm called ‘LayTracks’, to automatically generate an all quad mesh that is adapted to the variation of geometric feature size in the domain is described. LayTracks combines the merits of two popular direct techniques for quadrilateral mesh generation—quad meshing by decomposition and advancing front quad meshing. While the MAT has been used for the domain decompositi...

متن کاملConformal multi-material mesh generation from labelled medical volumes
Generating accurate volume meshes from segmented image volumes is important in certain medical applications. One application is finite element analysis (FEA) for orthopaedic pre-operative planning. The resulting FEA models can be used in patient-specific, bio-mechanical simulations and implants positioning. Currently available software packages for volume meshing of segmented data can generate ...
متن کاملbounded subset of R n has the same homotopy type as its medial axis
Medial axis Transform is sometimes used as an intermediate representation in algorithms for meshing or recognition of shapes from digitized data. This raises the question whether the Medial Axis captures fundamental topological invariants of the object. The (positive) answer has been known already in the case of smooth objects. The main result presented here is the homotopy equivalence of any b...
متن کاملSemi-Structured Mesh Generation Based on Medial Axis
A three-dimensional, medial-axis-based mesh generator is described. First the medial axis of the geometry to be meshed is constructed, then quad-dominant meshes on the medial surface are generated and extruded to the boundary at both sides of the medial surface. The resulting single cell layer is subdivided in direction normal to the boundary, yielding columns of hexahedral and three-sided pris...
