> 中文摘要: 发型的真实感和交互性之间的有效折衷是发型建模面临的一个重要问题.提出了一种交互式发型建模方法,使得用户可以通过交互操作处理发型的整体和局部特性.利用基于矢量场的发型建模方法来生成发型的整体形状.用户可通过三类不同的发型曲线所生成的约束来交互控制发型生成.利用发束模型表示发型并定义了若干基于发束的编辑操作使得用户可以交互控制发型的局部细节.实验结果表明,该方法在保证发型真实感的基础上提高了交互性和实时性.
Abstract:To support hairstyling effectively, it’s crucial for hairstyling tools to find a tradeoff between realism and interaction. This paper presents an interactive hairstyling method which can handle both global and local details of the hairstyle. Vector field based hairstyling method is used to generate the global shape of the hairstyle. This paper defines three different kinds of hairstyle curves which indicate the boundary constraints of vector field so that the user can control the hairstyle generation interactively. Hair wisp model is also used to represent hairstyles and several wisp based editing operations are defined, such that users can control the local details of the hairstyle. Experimental results prove that the proposed method provides more interaction and computation efficiencies without lost of hair realism.
