def mesh_draw_vertices(mesh,
keys=None,
color=None):
"""Draw a selection of vertices of the mesh.
Parameters
----------
mesh : :class:`compas.datastructures.Mesh`
A mesh object.
keys : list (None)
A list of vertex keys identifying which vertices to draw.
Default is to draw all vertices.
color : str, tuple, dict (None)
The color specififcation for the vertices.
Colors should be specified in the form of a string (hex colors) or as a tuple of RGB components.
To apply the same color to all vertices, provide a single color specification.
Individual colors can be assigned using a dictionary of key-color pairs.
Missing keys will be assigned the default vertex color (``self.defaults['vertex.color']``).
Default is use the color of the parent layer.
Notes
-----
The vertices are named using the following template: ``"{mesh.name}.vertex.{id}"``.
This name can be used afterwards to identify vertices of the mesh in the Rhino model.
Examples
--------
