本文提出了基于B样条型代数三角多项式插值样条（简称 ATBI样条）的四元数插值的扫掠面造型设计方法。分别利用ATBI样条进行扫掠面的截线和脊线设计、四元数样条进行扫掠面的标架设计，提高了曲面生成的效率，很好地解决了曲面的朝向和旋转问题。实验结果表明，基于 ATBI样条的四元数插值的扫掠面造型设计具有良好的光滑性，设计效率高。%This paper researches a approach of skinning modeling and design by quaternion interpolation based on ATBI -Spline.Designing the Section Curve and Spine curve by ATBI-Spline, and designing the frame by quaternion interpolation, rai-ses the effects of surface modeling, and figures out the orientation on rotation of surface.By experiments the skinning modeling of quaternion interpolation Spline based on ATBI-Spline is smoothness and efficiency.
