摘要
A shape blending algorithm of 2-D curved shapes is presented in this paper. A curvedshape is represented by a closed Non-Uniform Rational B-Spline(NURBS). We determine the inter-mediate shapes by interpolating the intrinsic definitions of the initial and final control polygons. Thisalgorithm can avoid shrinkage resulted from linear vertex interpolation and produce smcoth intermedi-ate shapes. Aliasing problems can also be easily eliminated.
