    ADAPTIVE SIMPLICIAL GRIDS FROM CROSS-SECTIONS OF MONOTONE COMPLEXES
    World Scientific Pub Co Pte Ltd ; 2000

    Abstract: We study the maintenance of a simplicial grid or complex under changing density requirements. The proposed method works in any fixed dimension and generates grids by projecting cross-sections of a monotone simplicial complex that lives in one dimension higher than the grid. The density of the grid is adapted by locally moving the cross-section up or down along the extra dimension.

    Triangulating Topological Spaces

    Abstract: Given a subspace [Formula: see text] and a finite set S⊆ℝ d , we introduce the Delaunay complex, [Formula: see text], restricted by [Formula: see text] . Its simplices are spanned by subsets T⊆S for which the common intersection of Voronoi cells meets [Formula: see text] in a non-empty set. By the nerve theorem, [Formula: see text] and [Formula: see text] are homotopy equivalent if all such sets are contractible. This paper proves a sufficient condition for [Formula: see text] and [Formula: see text] be homeomorphic.

    SINK INSERTION FOR MESH IMPROVEMENT
    World Scientific Pub Co Pte Ltd ; 2002

    In: International Journal of Foundations of Computer Science, World Scientific Pub Co Pte Ltd, Vol. 13, No. 02 ( 2002-04), p. 223-242
    Abstract: We propose sink insertion as a new technique to improve the mesh quality of Delaunay triangulations. We compare it with the conventional circumcenter insertion technique under three scheduling regimes: incremental, in blocks, and in parallel. Justification for sink insertion is given in terms of mesh quality, numerical robustness, running time, and ease of parallelization.

    FAST SOFTWARE FOR BOX INTERSECTIONS
    World Scientific Pub Co Pte Ltd ; 2002

    In: International Journal of Computational Geometry & Applications, World Scientific Pub Co Pte Ltd, Vol. 12, No. 01n02 ( 2002-02), p. 143-172
    Abstract: We present fast implementations of a hybrid algorithm for reporting box and cube intersections. Our algorithm initially takes a divide-and-conquer approach and switches to simpler algorithms for low numbers of boxes. We use our implementations as engines to solve problems about geometric primitives. We look at two such problems in the category of quality analysis of surface triangulations.
