2D and 3D pattern iteratively,residual strain in the projected pattern can be reduced.
By this strain reduction method,resulting flat patterns can be obtained.
By considering the physical properties of the fabric material such as maximum
elastic allowance and maximum shear angle allowance during the strain reduction,
even the optimum shapes of patterns for different fabric material can assumed to be
obtained.Some examples of flat patterns are shown in Figure 9.Strain reduction is
terminated after the rate of change in total strain reached a predefined threshold value.
The distribution of residual strain is visualized on the flattened patterns to guide the
users for the better placement of darts.
However,as the number and positions of darts are determined entirely by the user
and therefore the physically optimum number and positions of darts cannot always be
obtained by this method.Of course,there are certain algorithms to determine the
optimum cutting lines for the flattening of undevelopable surfaces (McCartney et al.,
1999,2000,Wang et al.,2004).But the applicable range of those methods are usually
limited and the cutting lines suggested by those methods usually have the arbitrarily
curved shapes and it is not desirable to introduce such complicated cutting lines to
garment patterns because of the limitations not only in the design but also in the
producibility of the garment.In this study,an automatic dart generation algorithm was
developed to make approximately linear darts along the mesh structure as described in
the manual dart definition method.Assuming the rectangular topology of a pattern,
darts can be initiated from one of its four edges and can be drawn inward
perpendicular to each edge as shown in Figure 10.The principle of this automatic dart

重复第2和3D样式,可以减少残余的张力在计划的样式.
由这个张力减少方法,发生的平的样式可以得到.
在张力减少期间,通过考虑织品材料的有形资产例如最大有弹性容限和最大剪角度容限,样式甚而最宜的形状为另外织品材料能假设获得.在变化率在总张力到达了一个被预定义的阈值之后,平的样式的有些例子在表9.张力减少显示被终止.
残余的张力的发行在被铺平的样式形象化引导用户为箭的更好的安置.
然而,当箭的数量和位置完全地取决于用户并且箭的完全最宜的数量和位置不能以这个方法总是获得.当然,有确定最宜的插队的某些算法为铺平undevelopable表面(等麦卡特尼,1999年,2000年,等Wang,2004).但是那些方法的可适用的范围通常是有限的,并且那些方法建议的插队通常有任意地弯曲的形状,并且介绍这样复杂的插队给服装样式由于局限不仅在设计,而且在服装的可生产是不中意的.在这项研究,一种自动箭世代算法被开发做大约线性箭沿滤网结构正如手工箭定义方法所描述.如图10.所显示,假设样式的长方形拓扑结构,箭从它的四个边缘之一被创始,并且可以是得出的在内垂线对每个边缘.这支自动箭的原则
