Hand Simulation Models in Computer Graphics

Abstract

the finger motions of a character playing a guitar by first building a motion capture database of hand configurations, and then, given a (sometimes partially specified) desired hand configuration, running the K-Nearest-Neighbors algorithm to search for the closest physically attainable configuration.Simply interpolating the data cannot produce highly detailed motion of the skin, such as buckling, and also suffers from some well-known artifacts, such as the collapse of volume around joints.The two approaches below remedy these problems.Abstract：This is a short survey of musculoskeletal hand models in computer graphics. We review a number of simulation models under six categories: example-based, passive muscles, joint torques, moment arms, dynamic strands, and volumetric.
