Note that both the Material and the Mesh created in the example should be Destroyed as they are native objects and will otherwise only be cleaned up when Resources.UnloadUnusedAssets runs.
Also, a common mistake when using the Mesh API that is worth mentioning: the properties vertices, triangles, normals, and so on, all return copies of their underlying data. So do not directly call these properties in a for loop, as every iteration will allocate an entire new array.
