Interactive modelling of volumetric musculoskeletal anatomy

We present a new approach for modelling musculoskeletal anatomy. Unlike previous methods, we do not model individual muscle shapes as geometric primitives (polygonal meshes, NURBS etc.). Instead, adopt volumetric segmentation where every point in our volume is assigned to muscle, fat, or bone tissue. provide an interactive tool the user controls via curves and visualize using rendering. Muscle enable intuitive yet powerful control over shapes. This representation allows us automatically handle intersections between different tissues (muscle-muscle, muscle-bone, muscle-skin) during automates computation of fiber fields. further introduce novel algorithm converting into tetrahedral surface geometry use downstream tasks. Additionally, skeleton authoring that users create skeletal anatomy starting from only skin mesh library parts.
