摘　　要：提出了基于3D晶格的毛发机械模型和机械变形方法,表现毛发串的体行为,晶格被作为粒子系统采用数学计算变形。毛发机械模型被作为与晶格模型中的各单独头发串片段弹性相关的一系列线性黏弹性晶格弹簧定义。发型足以快速实时表现,同时保留了毛发的特定行为,获得足够的多样性模拟各种复杂发型。用多项式元球模型处理毛发和身体表面之间碰撞。毛发模型具有很高的实时性能和通用性,可达到准确性和计算速度之间的最佳折中。An efficient 3D lattice mechanical model of the hair and mechanical deformation approach which represents the volume behavior of the hair strands is introduced. The lattice is deformed as particle system using advanced numerical methods. The mechanical model of the hair is defined as a sum of linear viscoelastic lattice springs relating the elasticity of each individual hair strand segment in the lattice model. Hairstyle which is sufficiently fast for real-time performance while preserving the particular behavior of the hair and maintaining sufficient versatility for simulating any kind of complex hairstyles. The collisions between the hair and the body surface with polynomial metaball model are dealt. The model of the hairstyle which can simulate any kind of complex hairstyles is sufficiently fast for real-time performance and sufficient versatility. The model can consider any compromises between accuracy and computation speed.
