【摘要】 推广了基于内在形状插值的多边形渐变算法,提出了具有边界约束的多重形状变形方法。通过在约束方程中引进边界控制条件得到适合一般曲线形状的插值算法,并利用具有指定边界约束的变换和形状插值器的构造,使该算法适合具有任意指定边界的多重曲线形状的混合变形,并给出了3D曲线形状边界约束的最优方程。通过2D形状渐变实验表明该算法的视觉效果良好。更多还原

【Abstract】 A scheme of multi-shape blending with constrained boundary by extending intrinsic shape interpolation is presented.A general curve shape interpolation algorithm is obtained by introducing boundary control conditions into restricted equation.The algorithm is applied to multiple curve-shape blending with given boundaries at all,by using transformation of restricted boundary and structuring shape-interpolator.The optimal equation of 3D curve-shape with constrained boundary is given.Experimental results of 2D-shape blending indicate that our scheme can generate visual-pleasing blending sequences.更多还原
