=============== geometry-simple

3D geometry library for python. The goal is to make geometric operations simple without a deep knowledge of linear algebra.

Installation

Download the latest version of the package from https://raw.github.com/sbliven/geometry-simple/master/dist/geometry-simple-0.2.tar.gz

In the resulting package, run

sudo python setup.py install

This will install the package for all users.

Dependencies

The library requires numpy (http://www.numpy.org) for the underlying linear algebra.

Examples

Import the library::

from geo import *

Create some geometric objects::

origin = Point(0,0,0)
xline = Line( origin, Point(10,0,0) )
yzplane = Plane( origin, Point(0,1,0), Point(0,0,1) )

Calculate distances and angles::

dist = Point(5,5,5).distance_to(yzplane)
use_degrees()
ang = xline.angle_to( yzplane )

Use linear regression to fit lines and planes::

from random import gauss
line_points = [ Point( gauss(x,.1), gauss(2*x,.1), 0) for x in xrange(10) ] #points around y=2x
line = Line(line_points)

plane_points = [ Point( gauss(0,10), gauss(0,10), gauss(0,.1)) for x in xrange(20) ] #points in the xy plane
plane = Plane(plane_points)

Easily apply affine transforms::

translation = Movement(origin, Point(5,-5,1))
Point(1,1,1).moved(translation)

rot90 = Movement(xline, Line(origin, Point(0,1,0)) )
Point(1,5,0).moved(rot90)

History

This library was created by uekstrom in 2008. The original code can be found at http://code.google.com/p/geometry-simple/

The code was expanded and moved to github by Spencer Bliven in 2013.
