Geometry-based Muscle Modeling for Facial Animation
We present a muscle model and methods for muscle construction that allow to easily create animatable facial models from given face geometry. Using our editing tool, one can interactively specify coarse outlines of the muscles, which are then automatically created to fit the face geometry. Our muscle model incorporates different types of muscles and the effects of bulging and intertwining muscle...
متن کاملThree-Dimensional Muscle-Tendon Geometry after Rectus Femoris Transfer
Introduction Rectus femoris transfer surgery is performed to improve knee flexion in persons with cerebral palsy who walk with a stiff-knee gait (Gage et al., 1987; Perry, 1987). In this surgery, the rectus femoris muscle is separated from the quadriceps tendon, tunneled through the subcutaneous tissue on the medial aspect of the thigh and sutured to one of the knee flexors – such as sartorius ...
متن کاملThree-dimensional muscle-tendon geometry after rectus femoris tendon transfer.
BACKGROUND Rectus femoris tendon transfer is performed in patients with cerebral palsy to improve knee flexion during walking. This procedure involves detachment of the muscle from its insertion into the quadriceps tendon and reattachment to one of the knee flexor muscles. The purpose of the present study was to evaluate the muscle-tendon geometry and to assess the formation of scar tissue betw...
متن کاملSarcomere Lattice Geometry Influences Cooperative Myosin Binding in Muscle
In muscle, force emerges from myosin binding with actin (forming a cross-bridge). This actomyosin binding depends upon myofilament geometry, kinetics of thin-filament Ca(2+) activation, and kinetics of cross-bridge cycling. Binding occurs within a compliant network of protein filaments where there is mechanical coupling between myosins along the thick-filament backbone and between actin monomer...
متن کاملRepeated contractions alter the geometry of human skeletal muscle.
The aim of this study was to investigate the effect of repeated contractions on the geometry of human skeletal muscle. Six men performed two sets (sets A and B) of 10 repeated isometric plantarflexion contractions at 80% of the moment generated during plantarflexion maximal voluntary contraction (MVC), with a rest interval of 15 min between sets. By use of ultrasound, the geometry of the medial...
