A Method of Deformation Expression of Soft Tissue in Virtual Operation Based on Surface Mesh Model

Based on the surface mesh model, this paper presents a method to calculate the deformation and deformation of soft tissue in real time. Through real-time collision detection and calculation of the collision point after the collision of the displacement, it can solve the deformation position calculation of soft tissue model during virtual operation, and display the deformation result in real-time rendering. This paper applies this method to the development of virtual dental implant surgery, the results show that the real-time performance of the cutting of gums and the drilling on the surface of the teeth can reach FPS (the number of frames per second) is greater than 30, and the visual display is smooth, which can meet the requirements of virtual surgery system.
