中文摘要: 主要研究了分形生长理论的基本模型——扩散有限凝聚(DLA)模型，分析并实现了DLA模型的计算机模拟方法，并对模型演变进行了讨论，得到了形式多样的凝聚效果。并且将DLA模型结合纱线和织物模拟相关技术和结论，用双侧线性DLA模型算法生成纱线毛羽模版，与基础纱线进行纹理合成，对纱线毛羽效果进行了较为真实的模拟。用这种方法能够较为逼真的反应出花式纱线不规则、随机多变且局部自相似的毛羽特征。
Abstract:This paper mainly studies the basic model of fractal growing theory—DLA Diffusion Limited Aggregation Model. The method of computer simulation of DLA model is analyzed and realized. And the evolvement of the model is discussed. Multiple styles of aggression effect are figured out. Combing DLA model with the techniques and conclusions of simulating yarns and fabrics, this paper also uses double-side leaner DLA algorithm to generate the fluffy template. It makes texture synthesis with basic yarn image to simulate the fluffy effect. The algorithms studied in this paper are effective to reflect the fluffy characteristics of fancy yarns: irregularity, random diversity and local self-similarity.
