Computer Animation of the human body is one of the most challenging pr
oblems. In this paper, we discuss the complexity of the musculoskeleta
l system for the purpose of human animation. As most of the human body
parts are cylindrical in nature, a Generalized Cylinder (GC) is a log
ical choice for modeling these parts. GCs are also well-suited for phy
siologic cross-sectional area analysis. The shape of a GC is modeled b
y a Non-Uniform Rational B-Spline (NURBS) surface or B-Spline curves.
Using the B-Spline curves, we have implemented an algorithm to find th
e line-of-action, and the volume centroid of the muscles and bones of
the upper arm. Based on the line-of-action and centroid calculations,
we have proposed a novel deformation algorithm which would avoid time
consuming equilibrium analysis.
