A novel technique for designing curves on surfaces is presented. The design specifications for this technique derive from other works on curvature continuous surface fairing. Briefly stated, the technique must provide a computationally efficient method for the design of surface curves that is applicable to a very general class of surface formulations. It(More)
Geometrical Criteria to Guarantee Curvature Continuity of Blend Surfaces Computer Aided Geometric Design (CAGD) of surfaces sometimes presents problems that were not envisioned in classical differential geometry. This paper presents mathematical results that pertain to the design of curvature continuous blending surfaces. Curvature continuity across normal(More)
The linearized perturbation method for fringe pattern analysis and its extension to multifringe analysis have been recently introduced [Hilaire, Ph.D. dissertation (Rensselaer Polytechnic Institute, Troy, N.Y., 1993)]. For isolating the error component that is due to information processing-as opposed to image-acquisition errors-experimental calibration(More)
