Description

This module defines two- and three-dimensional geometrical vectors. gVectors support the usual mathematical operations ( v1, v2: gVectors, s: scalar):

v1+v2: addition
v1-v2: subtraction
v1*v2: scalar product
s*v1: multiplication with a scalar
v1/s: division by a scalar
v1.cross(v2): cross product
v1.length(): length
v1.normal(): normal vector in direction of v1
v1.angle(v2): angle between two vectors
v1.x(), v1[0]: first element
v1.y(), v1[1]: second element
v1.z(), v1[2]: third element

The module offers the following items for export:

gVector(x,y,z): the constructor for vectors

Note:

gVector elements can be arbitrary objects on which the standard mathematical operators plus the functions sqrt and arccos are defined.Mostly copied from Konrad Hinsen's (<hinsen@ibs.ibs.fr>) Vector.py by Berthold Höllmann.
