Modeling and Simulation of Skeletal Muscle for Computer Graphics: A Survey

AbstractMuscles provide physiological functions to drive body movement and anatomically characterize body shape, making them a crucial component of modeling animated human figures. Substantial efforts have been expended on developing computational models of muscles for the purpose of increasing realism and accuracy in a broad range of applications, including computer graphics and biomechanics. We survey various approaches that have been employed to model and simulate muscles both morphologically and functionally. Modeling the realistic morphology of muscle requires that muscle deformations be accurately depicted. To this end, several methodologies have been presented, including geometrically-based, physically-based, and data-driven approaches. On the other hand, the simulation of physiological muscle functions aims to identify the biomechanical controls responsible for realistic human motion. Estimating these muscle controls has been pursued through static and dynamic simulations. We review and discuss all these approaches, and conclude with suggestions for future research.PDF
