摘要
This paper describes some of the major challenges encountered by Physna Inc.in developing an internet-scale search engine for three-dimensional (3D)models. The discussion focuses on the most significant data management issuesin this domain, including model acquisition, diversity of file formats, shaperetrieval, intellectual property, the legality of web crawling, and trustworthycomputing. The paper gives an overview of these topics, as well as some of thegeneral design choices that were made in the course of building the Thangssearch engine. While numerous works have been published on the topic ofalgorithms for 3D similarity search, this paper is the first to discuss thereal-world challenges that arise in building a practical, internet-scale, 3Dsearch engine.
