.. py:module:: polygon

The class Polygon
=================
	       

The class :py:class:`Polygon`  represents a polygon as its topologically sorted sequence of vertices.

.. py:class::  Polygon(color, vertices)
	      
   .. rubric:: Class methods:

   .. py:method:: from_dict(dic)

      returns a Polygon from a :py:class:`dict`
   
   .. rubric:: Attributes:   
   	    
   .. py:attribute:: color
		  
      the color of the polygon, an (R, G, B) tuple 

   .. rubric:: Methods:
      
   .. py:method:: to_dict()

      Returns a :py:class:`dict` 

   .. py:method:: add(p)

      Adds the given :py:class:`Point` to the polygon
      
   .. py:method:: bounding_box()

      To be implemented. Returns the bounding box of the polygon (:py:class:`Rectangle`)

   .. py:method:: rasterization(mtx)

      To be implemented. Returns a list of pixels  :py:class:`~point.Point`  corresponding to the polygon's rasterization
      with the given window-to -viewport transformations mtx
