add_vertex

Mesh.add_vertex(point, *args, **kwargs)[source]

Create and add new vertex.

The first point added to a mesh determines the dimensionality of all mesh vertices.

Parameters:

point (array_like or float) – Vertex coordinates.
*args – Variable number of scalars.
**kwargs – Attribute name and value pairs.

Raises:

ValueError – If point has the wrong shape.

Returns:

The newly created Vertex instance.

Return type:

Vertex

Note

When adding a new vertex all vertex data blocks are extended by a correponding value:

either by using the default value specified when the data block was added,

or by using a value provided as keyword argument.

Values specified as keyword arguments that don’t fit this pattern are added as Vertex instance attributes and only availabe as attributes of this particular instance.
