“…Using as an example a latitudinal dimension of six with four segments for the muscle compartment, the number of tetrahedrons would be 72, which is around 1% of the total number of tetrahedrons used in the demonstration of Berranen et al . that had a performance result of 45 Hz.…”

Physics-based simulation of systems such as virtual humans has benefited from recent advances in muscle actuation. However, to be manageable for motion controllers, muscles are usually solely represented by their action line, a polyline that does not include data on the tridimensional geometry of the muscle. This paper focuses on combining, by a controllable enhancement process, a functional and biomechanical model of musculotendon units with its high resolution geometrical counterpart. The method was developed in order to be invariant to spatial and polygonal configurations and to be scalable in both longitudinal and latitudinal directions. Results with 48 musculotendon units for the lower body show a drop of 84% with respect to the number of vertices when compared with the high resolution model, while maintaining the functional information. A real-time simulation experiment resulted in a runtime of 135 Hz. that use biomechanical models, such as wound or musculoskeletal injuries simulation, orthopedic training, and validation of musculoskeletal pathologies for animated characters, can benefit from our method. The main contribution of this paper is a novel method to enhance the scalable geometry of anatomical meshes that we demonstrate for the purpose of MTU modeling. A scalable geometrical model for musculotendon units results and we give concluding remarks with hints at future applications and improvements in section 6.

“…Berraren et al . used volumetric meshes with a modified Hill's model for real‐time deformation analysis where contractile muscle forces operate between adjacent nodes of the mesh. This is one of the few recent works that shows promising real‐time performance, although the result included a single muscle.…”

“…Lee et al [LGK*12] review visual approaches, which often use 3D surface models, for modeling muscle deformation and simulation of skeletal muscle functions at this scale. Experts are chiefly interested in understanding the shape deformation that skeletal muscle undergoes during contraction and relaxation [BHGG12]. Visualizations represent muscles at different degrees of abstraction to serve different objectives in a simulation, e.g., a single action line to show the axis of movement [NT98] or reconstructing and simulating a subset of muscle fibers that capture the overall shape of the muscle as it deforms [KK14; KČ20; RMS20].…”

Combining elements of biology, chemistry, physics, and medicine, the science of human physiology is complex and multifaceted. In this report, we offer a broad and multiscale perspective on key developments and challenges in visualization for physiology. Our literature search process combined standard methods with a state-of-the-art visual analysis search tool to identify surveys and representative individual approaches for physiology. Our resulting taxonomy sorts literature on two levels. The first level categorizes literature according to organizational complexity and ranges from molecule to organ. A second level identifies any of three high-level visualization tasks within a given work: exploration, analysis, and communication. The findings of this report may be used by visualization researchers to understand the overarching trends, challenges, and opportunities in visualization for physiology and to provide a foundation for discussion and future research directions in this area.
