| Abstract | This report summarizes the ndings and recommendations of the authors concerning the usefulness of subdivision surfaces for geometric modeling, and in particular for engineering applications. The work described is a result of a three-month collaboration of the authors during the visit of the second author to Boeing in the Summer of 2001. Executive Summary The objective of this project was to investigate the usefulness of subdivision surfaces for geometric modeling, and in particular for engineering applications. Subdivision surfaces are a new type of surface representation that has several advantages over traditional surface representations, most notably the ability to model surfaces of an arbitrary topo-logical structure. As a result of researching the subject, and implementing, extending and experimenting with a particular subdivision algorithm, we arrived at the following two conclusions. First, subdivision surfaces, in their current state of development, are not ripe for a major utilization in Boeing geometric modeling systems. We base this conclusion on the following observations There are currently no subdivision algorithms that generate suuciently smooth surfaces. There are too many unanswered questions related to critical requirements for engineering applications. See Section 7 for more details. A thorough comparison has not been made between subdivision surfaces and traditional surface representations. 1 Our second conclusion is that subdivision surfaces have enough potential to warrant further investigation. To that eeect, we make the following recommendations: Investigate ways to overcome the more severe shortcomings related to engineering applications. Conduct a thorough comparison between subdivision surfaces and traditional surface representations. Incorporate a limited subdivision capability into a Boeing geometric modeling system. The purpose of this would be to allow users to experiment with subdivision surfaces in order to provide feedback for further evaluation. |
