In this paper we present a point based potential field mechanics model for suture interaction. We study extended models to represent suture behaviors such as bending, stretching, twisting, which can be used in haptic rendering of knotting and unknotting tasks. In this paper, one-dimensional single point-samples and adaptive point-samples are studied and compared. In the adaptive model description, we develop a novel LOD(Level of detail) and resampling method using fluid particle flow model. A multi-resolution suture model is constructed based on the proposed LOD. Experimental studies demonstrate the feasibility of our proposed model for knotting and unknotting of the suture and can offer an adaptive and stable modeling environment for both graphic and haptic rendering. In addition, through the tuning of several key parameters, different material behavior such as elasticity can be obtained.
