vertex -package:algebraic-graphs

Abstract representation of vertices.
Specify the (x, y, z, w) coordinates of a four-dimensional vertex. This must only be done during renderPrimitive, otherwise the behaviour is unspecified. The current values of the auxiliary vertex attributes are associated with the vertex. Note that there is no such thing as a "current vertex" which could be retrieved.

A vertex represents a 2D point in the image. NOTE: the vertex coordinates are in the same scale as the original image. See: newVertex smart constructor.
