Maya API从现有网格中添加/删除顶点/边
[英]Maya API add/remove vertices/edges from existing mesh
问题描述
Is there a way to add/remove vertices, edges and faces from existing meshes with Python API? 
有没有一种方法可以使用Python API从现有的网格中添加/删除顶点，边和面？ I found a few question around the web about this, but all without answer. 我在网上发现了一些与此有关的问题，但都没有答案。

In OpenMaya.MFnMesh there are some methods for this: 在OpenMaya.MFnMesh中 ，可以使用一些方法：
- To delete: 删除：
- deleteEdge(edgeId, modifier=None) -> self deleteEdge（edgeId，修饰符=无）->自
- deleteFace(faceId, modifier=None) -> self deleteFace（faceId，修饰符=无）->自我
- deleteVertex(vertexId, modifier=None) -> self deleteVertex（vertexId，修饰符=无）->自我
- deleteEdge(edgeId, modifier=None) -> self
- To add: 加上：
- addPolygon(vertices, mergeVertices=True, pointTolerance=kPointTolerance, loopCounts=None) -> faceId; addPolygon（vertices，mergeVertices = True，pointTolerance = kPointTolerance，loopCounts = None）-> faceId; Which merges vertices within a certain range (pointTolerance). 合并一定范围内的顶点（pointTolerance）。
- addPolygon(vertices, mergeVertices=True, pointTolerance=kPointTolerance, loopCounts=None) -> faceId;
So it seems like you cannot just create single vertices and then properly connect them with edges and faces, but you have to define a complete polygon. 因此，似乎不能只创建单个顶点，然后将它们与边和面正确连接，但是您必须定义一个完整的多边形。
If there are other solutions I would be happy to know! 如果有其他解决方案，我将很高兴知道！
