+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.
