An efficient mesh deformation method for mass-spring muscle models

Abstract

This paper will consider a framework for simulation of musculoskeletal system via mass-spring system as the target application. The framework uses a mass-spring systems to simulate the muscle fibres of each muscle and an additional triangle model to visually represent the surface of the muscles. This requires establishing some relationship between the two models so that when some nodes of the mass-spring model move, i.e. the object deforms, this deformation is correctly carried over to the visualization. Mean Value Coordinates are often used for this purpose. In this paper, we will present a simpler method that produces deformation that is visually similar to that by the Mean Value Coordinates while consuming less memory and time.
