class pydy_viz.light.PointLight(*args, **kwargs)

Creates a PointLight for the visualization The PointLight is inherited from VisualizationFrame,

It can also be attached to dynamics objects, hence we can get a moving Light. All the transformation matrix generation methods are applicable to a PointLight. Like VisualizationFrame, It can also be initialized using: 1)Rigidbody 2)ReferenceFrame, Point 3)ReferenceFrame, Particle Either one of these must be supplied during initialization

Unlike VisualizationFrame, It doesnt require a Shape argument.
