Polypropylene (PP) based hernia mesh often shows multiple post-surgery complications due to lack of biocompatibility, poor cell attachment, and unwanted tissue adhesion. These limitations can be addressed by material designing surface modification a with side-specific properties such as the visceral side (facing intestine) low protein attachment parietal incision) improved for normal healing. H...

In this research work, cut mesh design optimization for the induction bonding process using genetic algorithms (GAs) is investigated to solve the problem of nonuniform heating, which leads to nonuniform temperature fields and temperature gradients exceeding the process window required for bonding. Cut patterns in the metal mesh can redirect the magnetically induced electric currents generated t...

A polar configuration is a triangle fan in a quad-dominant mesh; it allows for many mesh lines to join at a single polar vertex. This paper shows how a single tensor-product spline of degree (3, 6) can cap a polar configuration with a C surface. By design, this C polar spline joins C with surrounding bi-3 tensor-product splines and thereby complements algorithms that smoothly cap star-like, mul...

Surface models containing billions of polygons are becoming more frequent in computer graphics. Mesh simplification is necessary for displaying such surfaces at interactive rates. We describe a novel method for simplifying polyhedral meshes while producing multiple levels of detail for progressive transmission and interactive exploration. Unlike previous work on mesh simplification, our method ...

We present an algorithm that computes the exact Hausdorff distance between two arbitrary triangular meshes. Our method computes squared distances for each point on each triangle of one mesh to all relevant triangles of the other mesh yielding a continuous, piecewise convex quadratic polynomial over domains bounded by conics. The maximum of this polynomial is the one-sided Hausdorff distance fro...

This paper presents a parallel programming environment for mesh generation. Our approach is based on overdecomposition. The programming environment supports: low-latency one-sided communication, global address space in the context of data/object mobility, automatic message forwarding and dynamic load balancing. These are the minimum requirements for developing efficient adaptive parallel mesh g...

The constructionof quadraticC 1 surfacesfrom B-spline control points is generalized to a wider class of control meshes capable of outlining arbitrary free-form surfaces in space. Irregular meshes with non quadrilateral cells and more or fewer than four cells meeting at a point are allowed so that arbitrary free-form surfaces with or without boundary can be modeled in the same conceptual frame w...
