摘　　要：为了缩短开发时间,减少织物设计开销,并在企业和客户间建立有效的沟通,提出了一种新的在二维虚拟场景中模拟显示织物真实感效果的实现方法.利用累加弦长样条曲线进行曲线拟合,在二维场景中建立曲边四边形,添加内部控制线来提高模拟精度及效果,使用双线性插值方法对它进行有限元网格划分;利用基于三角形的纹理映射技术、目标区域剪裁以及像素点颜色合成技术进行织物图案到曲面网格的纹理映射.在D e lph i7集成开发环境下进行编程.设计人员可以通过该系统在设计之初就对所设计产品的效果进行模拟.介绍了系统框架、实现原理以及核心算法,并针对纹理映射技术给出详细且行之有效的方法.通过上述方法,获得了较好的纹理映射模拟效果,具有广泛的应用前景.To shorten developing time, reduce cost of textile design and build more effective communication between enterprises and customers, a new realization method to simulate real effect of textile in 2D virtual environment is presented. By utilizing accumulative bowstring arc length curve for curve fitting, and adding inner control lines in curving quadrangle, established in 2D virtual environment, simulation effect and accuracy are improved and then finite element mesh is generated with bilinear interpolation. Finally by using the texture mapping technology based on triangle mesh, objective area trimming and color synthesis of pixel point technologies, mapping between texture and curving mesh is completed. Designers can simulate the effect of the designed products in this system, programmed in Delphi7, at the beginning of design. System architecture, implementation principle, and core algorithm are introduced and then a detailed and effective method for texture mapping is provided. Through the above method, a good simulation effect of texture mapping is gained, which demonstrates that this method has a wide application prospect.
