Better Pasting via Quasi-Interpolation

Abstract

Surface pasting is a hierarchical modeling technique that places feature surface atop base surface with approximate continuity. In this paper, we describe using quasi-interpolation to set the boundary control points of the pasted feature. To achieve interactive performance for surface pasting, we modified the coefficients and weights of quasi-interpolation, and devised an efficient sampling scheme. The new surface pasting technique is actually faster than the original surface pasting method when using the same number of feature control points, with a much lower discontinuity between the feature and base surface.
