Abstract: Method for constructing N-sided patches with B-spline on
the basis of Gregory N-sided surface theory is presented. The attributes
make the N-sided patches be able to interpolate the boundaries and
derivatives over the boundaries which are represented with 3-ordered B-spline.
Firstly Gregory method is used to construct a N-sided patch, and then,
according to the patch’s data , an N-sided surface can be generated with
n rectangular surface patches satisfying G1 continuity between those
patches.
Key words: Computational geometry Non-four-sided patch NURBS Surface
fitting Autobody design
