Vertex

class m3sh.hds.Vertex(index, parent=None)[source]

Vertex base class.

Vertices are considered as abstract topological entities. Vertex coordinates are assigned when a vertex becomes part of a mesh. Its coordinates can then be accessed via the point property .

Parameters:

index (int) – Vertex index.
parent (Mesh, optional) – The parent mesh object.

Note

In addition to index, implementations of the special functions __int__() and __index__() are provided. The latter makes it possible to use vertex instances as list indices.

Attributes

`boundary`	Topological state.
`degree`	Vertex degree.
`deleted`	Internal state.
`flags`	Vertex flags.
`halfedge`	Outward pointing halfedge.
`index`	Vertex index.
`isolated`	Topological state.
`point`	Vertex coordinates.

Special methods

`__index__`()	Vertex index.
`__int__`()	Vertex index.
