Abstract This paper presents a novel approximating method to construct highprecision single-patch representation of B-spline surface from a multi-patch representation for isogeometric applications. In isogeometric analysis, multi-patch structure
is not easy to achieve high continuity between neighboring patches which will reduce
the advantage of isogeometric analysis in a sense. The proposed method can achieve
high continuity at surface stitching region with low geometric error, and this technique exploits constructing the approximate surface with several control points are
from original surfaces, which guarantees the local feature of the surface can be
well-preserved with high precision. With the More >
