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 the use of quasi-interpolation to set the boundary control points of the pasted feature. To achieve interactive performance for surface pasting, we modify the coefficients and weights of quasi-interpolation and devise 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.
