Real-time simulation of thread and knot-tying with visual and force feedback is an essential part of virtual reality (VR) laparoscopic training. This paper presents a physicsbased thread simulator that enables realistic knot tying at haptic rendering rate. The virtual thread follows Newton's law and behaves naturally. The model considers main mechanical properties of the real thread such as stretching, compressing, bending and twisting, as well as contact forces due to selfcollision and
