Title: Two Modeling Primitives for Computer Aided Geometric Design

Abstarct: Computer Aided Geometric Design concerns development of algorithms and accompanying software, towards design of parts and structures with a high degree of numerical precision. Target application domains include design of automobiles, aircrafts and buildings, among others. In this talk we discuss two kernel level modeling primitives. First, we propose a comprehensive algorithmic framework for computation of solid sweeps. This involves computing the boundary of the swept volume generated by moving the input solid along the input one-parameter-family of rigid motions in three dimensional space. In particular, we discuss local issues such as the parametrization of the boundary surface, detection and elimination of self-intersections, as well as global issues such as body-check and the topological data associated with the swept volume. Several examples from a prototype implementation in the ACIS modeling kernel will be shown. Applications include CNC machining verification, product handling and collision detection. Second, we demonstrate a robust computational interface for precise modeling of microstructures towards 3D printing. This is achieved through functional composition of B-spline functions and allows separate design of the micro and the macro structures of an object. In particular, we demonstrate construction of recursive, fractal-like microstructures which are composed of trivariate tiles with C0-discontinuities. Applications include design of porous and composite materials. This is joint work with Milind Sohoni, Bharat Adsul and Gershon Elber.

Speaker Bio: Jinesh is a researcher in the field of computer aided geometric design. His areas of interest include solid modeling and shape analysis. He obtained his PhD from IIT Bombay and thereafter was a post doctoral fellow at Technion - Israel Institute of Technology.
