HOLE PATCHING IN 3D UNSTRUCTURED SURFACE MESH AMITESH KUMAR

By Roy Koomullil

Abstract

A three-dimensional object of interest in a volumetric data can be visualized using direct surface rendering methods or volume rendering approaches. Volume rendering is a visualization technique without providing the geometry information at all. However, an engineering analysis requires watertight surface geometry information of the object. Thus a three-dimensional object representation for the visualization using direct surface rendering may not necessarily be valid for engineering analysis, as such models are not necessarily watertight. Obtaining watertight surfaces has been a challenging task in the field of computational engineering due to presence of deficiencies such as gaps and holes in the surfaces. The focus of this thesis is to address the need to patch holes in the surfaces to obtain a watertight geometry. Most of the methods available for hole patching today are limited in their utility, in most cases, by the method with which the geometric model has been originally obtained. This research work provides an innovative and original method of creating surface patches for topologically simple holes in unstructured discrete geometry using parametric NURBS (Non-Unifor
