Abstract: In traditional 3d fabric simulation, because of the randomness effect of fabric movement state,fabric simulated 3d coordinate in athletic process will occur dislocation, and motion state mutations increase movement process of the pa- rameters of the fabric of 3d dynamic randomicity,making the fabric 3d coordinate produces small neighborhood mutation and 3d photo-realistic fabric simulation result is not quite clear. In order to solve this problem, this paper proposed a small neighborhood 3d movement constraint estimate fabric simulation algorithm, which uses markov movement model and the collision of the movement of the randomness to constraint fabric range limited area, and realize the real 3d fabric of computer simulation. Experiment results show that this method can achieve real 3d simulation fabric, real degrees higher.
