Abstract
Systems and methods involving surface fitting are provided. In this regard, a representative method includes: receiving information corresponding to discrete data points of a portion of a surface; determining curvature estimates associated with the data points prior to performing curve fitting with respect to the data points; identifying curvature shock based on the curvature estimates, the curvature shock being defined as a curvature threshold corresponding to an absolute value of curvature between adjacent data points; breaking C2 continuity between adjacent data points exhibiting curvature shock; and performing surface fitting with respect to the data points to generate Non-Uniform Rational B-Splines (NURBS) data such that breaks in the C2 continuity associated with curvature shock are maintained in the NURBS data.
