Abstract It is very important to build a soft tissue cutting model for virtual surgery simulation system. Meshbased soft tissue cutting models take tissue cutting process as a mesh division between surgical tools and geometry mesh of soft tissue. As the soft tissue cutting process involves complex biomechanical problems, it is not easy to realize real-time interaction, which seriously affects virtual surgery simulation. In contrast, meshless soft tissue cutting models, breaking the limitations of meshbased model, have a great advantage in tactile/visual fidelity and realtime interaction. In this paper, we provide an overview of meshless soft tissue cutting models from the rendering quality and speed of force and visual feedback. Challenges in current studies are also discussed and summarized, and concerns that require further investigations are also included.
