The authors have presented the simulation of cables, hoses and wiring harnesses in an interactive environment in real-time. Modeling of cables and hoses is based on their physical properties, which can either be found in tables or be obtained by measurement. The simulation itself is designed to be accurate, precise and fast by applying a combination of well-chosen algorithms and methods from computational mathematics. Especially, fast contact detection and accurate resolution in real-time are novel and show that a physically based approach to the simulation of contact between cables/hoses and a rigid environment are viable and practical. The accuracy of the authors' contact resolution has been demonstrated by means of an elaborate comparison with other results in literature. Robustness is achieved for a large variety of custom contact situations. Nevertheless, ambiguous physical situations cannot yet be solved. This issue will be addressed in future releases of the authors' software. The cables, wiring harnesses and hoses have been evaluated together with several automotive companies. The results of experimental validation show that their calculations coincide at high accuracy with the experimentally measured shapes and are more accurate than other methods. The authors achieve a precision of less than 1 % relative to the length of the cable/hose with an update rate of more than 20 frames per second on a P4 3GHz PC.
