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.
