【摘要】 能量法是一种目前被广泛采用的光顺方法，但当数据点较多时，能量法的存储量和计算量都很大。本文研究Ｂ样条曲面先顺的分片能量法。应用该法可以在保持光顺效果和能量法基本一致的前提下，大大地减少存储量和计算量。实例表明，这是一种行之有效的曲面光顺方法。更多还原

【Abstract】 The energy interproximation is a method widely used in fairing curves and surfaces. However, when there are many data points, the storage space is too much and computing speed tooslow. Apparently, it is not suitable for interactive surface fairing in CAD/CAM systems. Inthis paper a piecewise energy method of fairing is presented and the boundary constraints is discussed. Though the method needs much less storage space with a similar result as that of energy methods, its computing Ospeed is much faster. Examples experienced show that it is satisfactory for surfaces更多还原
