摘　　要：为提升机织物仿真的真实感效果,降低因反复试织打样产生的资源损耗,针对仿真过程中织物建模复杂、模拟效率较低等问题,提出了一种基于带状纱线模型的织物建模方法,结合真实纱线图像的纹理映射,实现机织物真实感快速仿真。通过将传统管状纱线模型简化为带状,利用Catmull-Rom曲线拟合纱线路径,根据纱线排列模型、织物组织模型对织物几何模型进行构建,同时通过参数化调整完善整体织物形态;通过采集纱线真实图像及图像预处理等步骤,配合纱线表面光照模型及阴影调整,利用PBR技术对纱线纹理进行真实感渲染。结果表明,该方法在简化机织物仿真流程的同时能够实时准确地预览纱线在织物中的呈现效果,提高机织物的设计效率。To enhance the realism of woven fabric simulation and reduce resource consumption caused by repeated trial weaving and sampling,a fabric modeling method based on a ribbon yarn model is proposed to address issues such as the complexity of fabric modeling and low simulation efficiency during the simulation process.By combining texture mapping of real yarn images,this method achieves rapid and realistic simulation of woven fabrics.The traditional tubular yarn model is simplified into a ribbon shape,and Catmull-Rom curves are used to fit the yarn paths.The geometric model of the fabric is constructed based on the yarn arrangement model and the fabric weave pattern,while parametric adjustments are applied to refine the overall fabric morphology.Through steps such as capturing real yarn images and image preprocessing,along with the yarn surface lighting models and shadow adjustments,physically based rendering(PBR)technology is employed to achieve realistic rendering of yarn textures.The results demonstrate that this method simplifies the woven fabric simulation process while enabling real-time and accurate previews of yarn appearance within the fabric,thereby improving the design efficiency of woven fabrics.
