はOpenMaya.MFnMesh.split（）を使用し、私のMaya PythonのAPIです。 MFnMesh.split、必要な情報：
[in] placements array that contains elements of the SplitPlacement enumeration. They represent where to place the new vertices for the split.
[in] edgeList array of edge IDs to be split, in order of their appearance in the split. There must be as many elements in this array as there are SplitPlacement::kOnEdge elements in the placements array.
[in] edgeFactors array of factors in the range [0,1] that represent how far along each edge must the split be done. This array must have the same number of elements as the edgeList array.
[in] internalPoints array of positions for the vertices that will be added inside existing faces. There must be as many elements in this array as there are SplitPlacement::kInternalPoint elements in the placements array. This array can be empty. Internal points should be specified on the face between the previous edge id and the next edge id.
