> 中文摘要: 传统布料和服装动态仿真主要通过网格模型进行模拟,并通过光照、材质和颜色设置进行渲染,布料与服装质感效果通常无法体现.提出一种新的基于纤维的质感布料建模与服装仿真算法.首先使用集合球约束粒子扰动的方法模拟纤维轮廓,然后根据纱线加捻的动力学和运动学原理模拟基于纤维的纱线构造方法,之后将纱线经纬编织组织结构与弹簧-质点模型结合起来,构造基于纤维块的织物布料模型,最后通过建立人体混合层次包围盒进行快速碰撞检测,实现由质感布料生成的服装动态仿真.实验结果表明,该方法可靠、有效,生成的布料能够体现出织物外观纤维级别的细节,对应的服装几何纹理和质感效果得到增强.

Abstract:Traditional cloth and garment simulation is normally based on the mesh model where cloth and garment are generally rendered according to the lighting, texture and color setting, which cannot fully reflect their photorealistic appearance. This paper proposes a novel fiber-based cloth and garment simulation algorithm that facilitates photorealistic appearance. The algorithm first uses the sphere set constraining the particle perturbation to express the contour of fiber, and then simulates the fiber-based yarn reconstruction helped by the dynamics and kinematics principle of yarn twisting process. Next, it combines the organization structure of the yarn warp knitting with the mass spring model to construct the cloth model based on the fiber blocks. Finally, it builds up the hybrid bounding volume hierarchy of the human body model to speed up the collision detection between the body model and the garment composed of the fiber based cloth, which helps achieving satisfactory dynamic simulation. Experimental results show that the presented method is valid and effective, as it can reflect the detail in the fiber level of the cloth models and express the geometric texture and the photorealistic appearance of garments.
