Abstract:

This thesis focuses on modelling intermuscular interactions in the context of muscle deformation using the Position Based Dynamics (PBD) method. The deformation method was extended to improve its consistency during simulation. Passive intermuscular interaction was introduced and implemented through a general deformable collision handling system. Additionally, a system for active muscle interaction was developed for the model, enabling physiologically accurate, motion-based, and synchronous muscle contractions during arbitrary movements. The results were rigorously verified against a similar method and evaluated for physiological accuracy, preservation of shape and volume, and muscle collision avoidance. The physiologically advanced model seems to hold a real-world application potential.
