The visualization simulation technology of cloth deformation based on mass-spring model is a hot field of research currently. Firstly, a review was made of several typical models of simulation technology of cloth deformation, with focus on the mass-spring model put forward by Provot. Then, the optimization methods of mass-spring model was discussed in respect of optimizing model parameters, improving stability of modeling system and mitigating hyperelastic phenomenon, and the advantages and disadvantages of the optimized models were compared. The simulation thought of combining computer vision technology with fabric physical model is proposed. And finally, its future research direction is prospected, suggesting that further study should be made in these aspects such as setting the evaluation system of the simulated result, improving the overall performance of the model and application fields for the mass-spring model, in order to assist manufacturers and designers to select and use fabrics more reasonably.
