This paper presents a real-time simulation approach for deformable cables and its application for the simulation of assembly tasks in a virtual environment. Based on our experiences from the design department with assembly simulations involving rigid objects we motivate the need for deformable objects, especially cables, by practical examples and explain our physically based simulation approach. The physical behaviour of a cable is simulated as a mass-spring model with generalized springs. The main objective is a physically plausible real-time simulation for cables of moderate complexity. In comparison to research done in the field of cloth simulation for computer animation, cables show a very stiff bending behaviour, which is modeled by the use of torsion springs. Special attention is given to the integration into the virtual environment for assembly simulation. Collision detection and response are necessary for the interaction with rigid bodies and with input devices used by the engineer.
