Progressive IsoContouring
نویسندگان
چکیده
We describe a hierarchical volumetric representation of input meshes yielding isocontour output progressively and with decreasing geometric error. The maximum tolerable error bound can be prespeci ed, or incrementally reduced receiving the extra detail in the isosurface with minimal redundancy. We use a hierarchical tetrahedral representation generated via recursive edge-bisections and approximating the input mesh. The recursive edge-bisection is coupled to the output isocontour improvement by local edge splits (connectivity change), local deformation (new vertex locations) and connectivity ips (change in topological type) yielding progressively better approximations to the isocontour approximation of the nest level mesh.

Interactive Isocontouring of High-Order Surfaces
Scientists and engineers are making increasingly use of hp-adaptive discretization methods to compute simulations. While techniques for isocontouring the high-order data generated by these methods have started to appear, they typically do not facilitate interactive data exploration. This work presents a novel interactive approach for approximate isocontouring of high-order data. The method is b...
متن کاملA Fast GPU Particle System Approach for Isocontouring on hp-Adaptive Finite Element Meshes
The hp-adaptive finite element (FE) method is a discretization scheme which is increasingly finding application in numerical solvers. Most existent visualization tools, however, are based on linear graphic primitives and corresponding low order interpolation schemes. Consequently, pragmatic approaches in such a setting follow a resampling strategy that may introduce a loss of information, prohi...
متن کاملFast Isocontouring For Improved Interactivity1
We present an isocontouring algorithm which is near-optimal for real-time interaction and modification of isovalues in large datasets. A preprocessing step selects a subset S of the cells which are considered as seed cells. Given a particular isovalue, all cells in S which intersect the given isocontour are extracted using a highperformance range search. Each connected component is swept out us...
متن کاملSharp Feature Preservation in Octree-Based Hexahedral Mesh Generation for CAD Assembly Models
This paper describes an automatic and robust approach to convert 3D CAD assembly models into unstructured hexahedral meshes that are conformal to the given B-Reps (boundary-representations) with sharp feature preservation. In previous works, we developed an octree-based isocontouring method to construct unstructured hexahedral meshes for manifold and non-manifold domains. However, sharp feature...
متن کاملA New Approach of Seed-Set Finding for Iso-Surface Extraction
Iso-surface extraction is one of the most important approaches for volume rendering, and iso-contouring is one of the most effective methods for iso-surface extraction. Unlike most other methods having their search domain to be the whole dataset, iso-contouring does its search only on a relatively small subset of the original data-set. This subset, called a seed-set, has the property that every...
