纺织CAD系统中基于B样条的撇丝的算法研究

THE RESEARCH OF ALGORITHM OF STROKE BASED ON B-SPLINE IN FABRIC CAD SYSTEM

在实现面向绍兴轻纺行业的纺织CAD系统的过程中,为了更好更高效地模拟撇丝这种特色工艺的计算机实现,描述了用户指定的过控制点的B样条插值算法,然后提出了用这种插值算法来生成撇丝图案的详尽的原理和算法,再提出了一组撇丝的生成算法,最后通过效果图展示了算法的效果。这种算法已经成功地运用到了面向绍兴轻纺行业的CAD系统中。

During the implementation of the fabric CAD system which faces to textile corporations in Shaoxing, in order to simulate the stroke, which is a characteristic technic, impressively and effectively, this paper first brings forward an algorithm of interpolation that uses B - spline curves which pass the setting points ,then describes the theory and algorithm used to produce images of stroke in detail ,next describes the algorithm of a group of strokes. At last two effect images show the effect of the algorithms. This kind of algorithms has already been used by fabric CAD system which faces to textile corporations in Shaoxing successfully.
