Computerised Muscle Modelling and Simulation for Interactive Applications

The main challenges of collision detection and handling in muscle modelling are demonstrated. Then, a collision handling technique is tested, exploiting the issue of muscle penetrating the bone in some circumstances, mainly when the movement is too rapid or the displacement of the bone is too high. Our approach also detects the problem, using Discregrid to see the immediate direction change towards the penetrated bone. Some alternatives to the described PBD (Position-Based dynamics) technique are presented: PBD with As-Rigid-As-Possible modification and radial basis function approach.
