Unified skinning of rigid and deformable models for anatomical simulations

Abstract: Figure 1: Our unified geometric skinning method for rigid and deformable bodies with two-way force coupling (left), is well suited for anatomical models that have a mix of hard and soft tissues, such as dynamic simulations of the tongue, jaw, skull, and vocal tract (right). AbstractWe propose a novel geometric skinning approach that unifies geometric blending for rigid-body models with embedded surfaces for finite-element models. The resulting skinning method provides flexibility for modelers and animators to … Show more

“…The classical (computer graphics) approach to modeling human avatars requires explicit physically-plausible modeling of human skin, hair, sclera, clothing surface, as well as motion under pose changes. Despite considerable progress in reflectivity modeling [2,18,38,70,72] and better skinning/dynamic surface modeling [23,44,60], the computer graphics approach still requires considerable "manual" effort of designers to achieve high realism [2] and to pass the so-called uncanny valley [46], especially if real-time rendering of avatars is required.…”

“…For example, for modeling the human airway, a disparate set of models describing the tongue, jaw, palate and pharynx can be connected together with a surface skin to form a seamless airtight mesh (Fig. 13), as described in [21]. This then provides a uniform boundary for handling air or fluid interactions associated with tasks such as speech or swallowing.…”

“…Later on, simultaneous multislice imaging made it possible to measure the area function directly using 3D images and also to develop 3D biomechanical models that are more realistic regarding the anatomy (eg, fiber direction of the muscles) and mechanical properties (eg, muscular hydrostat) of the structures. Despite the progress in biomechanical modeling, little attention yet has been paid to reconstructing the complex vocal tract geometry in 3D, and the area function is still the most common representation.…”
