Geometry Module
===============

The geometry module is used to obtain information about the points and vertices of a ployhedra.

.. py:class:: Points

This class represents points in space.

    .. py:method:: isorigin(self)
    
        Return true is given point is the origin.
        
    .. py:method:: 
        
.. py:class:: Vector

This class represents displacements in space.        

    .. py:method:: angle(self, other)
    
        Retrieve the angle required to rotate the vector into the vector passed
        in argument. The result is an angle in radians, ranging between -pi and
        pi.

    .. py:method:: cross(self, other)
    
        Calculate the cross product of two Vector3D structures. 

    .. py:method:: dot(self, other)
    
        Calculate the dot product of two vectors. 
        
    .. py:method:: __trudiv__(self, other)
    
       Divide the vector by the specified scalar and returns the result as a
       vector.
