3D Model Reconstruction,Deformation,and Cutting Simulation of Human Abdominal Organs
By converting traditional surface models into body models,deformation,cutting,and collision simulation of human abdominal structures including multiple organs such as the liver,stomach,colon,and gallbladder were achieved.Firstly,based on the anatomical structure of the physiological abdominal cavity,3D model of various organs within the abdominal cavity were reconstructed.Then,based on the physiological positions and suspension methods of various organs in the abdominal cavity,determine the relative positions between the 3D model,and set reasonable boundary constraints on the 3D model.Next,converted the 3D model into a voxel based voxel model.Finally,the body model was endowed with biome-chanical properties and simulated.The experimental results show that this method can generate realistic and reasonable deformation,cutting,and collision simulation effects while ensuring stable simulation frame rates,and can still meet the requirements of visual real-time performance even in the presence of multiple organs.
