White paper introduction

In this whitepaper, Schuyler Greenawalt reviews fundamental problems inherent in non-uniform rational B-splines (NURBS), the underlying technology used in nearly all commercial CAD programs. He then introduces the T-Splines technology and discusses how T-Splines addresses these shortcomings. Finally, Schuyler shares a case study of how he used T-Splines to accurately model an entire experimental aircraft and how the T-Splines model saved him 75% of his iterating time.
