This module provides two Python classes that represent the
principal modeled objects: points and transforms. See
Section 3.1, “The
Pt class: A Cartesian
point” and Section 3.2, “The
Xform class: Coordinate
In addition to importing the
homcoord module, you will
probably also want to import the
package. For documentation on this package, see the SciPy homepage.
This version of the package is designed for 2-dimensional coordinates. To handle 3-dimensional coordinates, there are two possible approaches:
Provide two completely separate packages, and call
the second one something like “
Provide one package that determines the dimensionality of the coordinates everywhere they are accepted as arguments. In this approach, it will be necessary to check that users do not mix 2- and 3-dimensional coordinates and transforms.
