Study on simulation of flexible fabric bend surface based on four-point interpolation method

In order to further improve the simulation of flexible fabric, it proposes a method for simulation of flexible fabric surface based on four-point interpolation in this paper. The specific research process is as follows. Firstly, the analysis of the fabric surface model based on four point interpolation method, then, using four-point interpolation method to subdivide the curves and surfaces of flexible fabric, finally, surface splicing and local modification are taken by four-point interpolation method, and using the comparative and experimental to verify the feasibility of four-point interpolation method. The result shows that the method based on four-point interpolation to simulate true flexible fabric is proposed in this paper, simulation accuracy can reach above 95%, which verifies the feasibility of the method.
