An Automatic Hole-Filling Algorithm for Polygon Meshes

Concerns about the environmental impacts of used and discarded products have recently led to enactment of laws that regulate the amounts of hazardous substances and recyclable content in products.The laws also make the Original Equipment Manufacturers (OEMs) responsible for recovery and proper treatment of these end-of-life products.In this two part paper, we present methodologies for OEMs to use the Product Lifecycle Management (PLM) framework to effectively meet the challenges posed by these regulations.In this second part, we outline a methodology that can enable case-by-case selection of the treatment strategy for incoming end-of-life products.To extract product information required for this selection, we develop rule-based heuristics for identification of joints directly from CAD assembly models, along with their type, size, location and orientation.
