However, the success of graphics in these arenas depends greatly on the efficiency of model creation and the realism of the animation or 3D image.;A common method for figure animation is skeletal animation using linear blend skinning (LBS). In this method, vertices are deformed based on a ...

线性混合蒙皮最开始是在工业界广泛使用,并没有发表论文,后来才被学术界研究。 形象意义。刚体运动时,每个顶点都可以根据关节移动计算出确定的新位置。但是如果除了刚体外,还有非刚体部位呢? 例如人体、人脸等,除了刚性骨骼,还有柔软的肌肉、皮肤。那这些肌肉、皮肤的顶点位移该怎么计算呢?blend skinning就是常用的方法...
1.2Linear Blend Skinning 图1:LBS流程示意图 为了讲清楚SMPL,必须先简单介绍一下什么是LBS(线性混合蒙皮),在人体建模领域,一般使用N=6890个顶点组成的Mesh来表示人体。再使用K=24个关节表示人体的关节,用字母J表示。对于不同高矮胖瘦的人,使用10维的参数β∈R10表示人的外形参数,也有论文叫identical信息,毕竟外形...
