Abstract

Freeform rational parametric curves and surfaces have been playing a major role in computer aided design for several decades. The ability to analyze local (differential) properties of parametric curves is well established and extensively exploited. In this work, we explore a different lifting approach to global analysis of freeform geometry, mostly curves, in IR 2 and IR 3. In this lifting scheme, we promote the problem into a higher dimension, where we find that in the higher dimension, the solution is simplified.
