摘要

在计算机图形学中,一维可变形物体或弹性棒被广泛用于表示线、发丝和弹性绳。这种物体具有难以处理的弯曲、拉伸和扭转行为。为了模拟可变形的物体,最近提出了一种简单的方法,称为晶格形状匹配(LSM) [Rivers and James 2007]。LSM可以处理从柔软物体到坚硬物体的可变形物体,并且具有无条件的稳定性。对于一维可变形物体,[Rungjiratananon et al. 2010]引入了一种简化的LSM模型,称为链形匹配(Chain Shape Matching, CSM),用一串由片段连接的粒子链来表示一维可变形物体。然而,LSM和CSM只能捕获弯曲和拉伸行为,而不能处理扭转行为。

Elastic rod simulation by chain shape matching with twisting effect
One-dimensional deformable objects or elastic rods are widely used to represent threads, hair strands and elastic ropes in computer graphics. Such an object has the bending, stretching and twisting behaviors which are difficult to handle. To simulate deformable objects, a simple method called Lattice Shape Matching (LSM) [Rivers and James 2007] was recently proposed. LSM can handle the deformable objects ranging from soft bodies to stiff objects with an unconditional stability. For one-dimensional deformable objects, [Rungjiratananon et al. 2010] introduced a simplified model of LSM called Chain Shape Matching (CSM), which represents the one-dimensional deformable object by a chain of particles connected by segments. However, LSM and CSM can capture only the bending and stretching behaviors, but cannot handle twisting.
