This paper presents a novel method on muscular modeling for a digital human. The unique feature is in that it models a muscle at the muscle fascicle level. By modeling a muscle from the internal structure, we aim at improving the visual reality and the efficiency in generating various kinds of muscles, compared with the conventional muscular modeling methods. We applied this method to twenty-five muscles of a human arm. Locating the generated muscles on a bone model and adding the skin model, we simulated the contraction of the muscles. As a result, we confirmed that the visual effect is very satisfactory. Moreover, we applied our GFFD (Generalized Free-Form Deformation) method to the muscular modeling. By automatically transforming the standard muscular model to the individual ones, the time to generate a model has greatly been reduced.
