Cloth simulation method based on grid convolution

The invention discloses a cloth simulation method based on grid convolution, and the method comprises the steps: enumerating adjacent neighbors at each vertex of a low-resolution cloth grid in an anticlockwise order to form a single ring, and carrying out the uniform sampling of the single ring according to the length; creating uniform sampling points along a piecewise linear curve at an interval of 1/(L-1); a priority queue of edges is formed based on the quadratic error, when the vertexes of the two end points are replaced by the midpoint, the edge with the lowest quadratic error is selected to be folded, and then the edge sharing the vertexes with the folded edge is marked as an unfoldable edge until the number of the vertexes is smaller than a preset proportion of the number of the vertexes at the beginning; pooling the region with rich wrinkles, copying the value of one input vertex to one or two output vertexes, and outputting a cloth simulation result. And ring-based convolution is designed, virtual ve
