Angus originally suggest matplotlib. The other proposed solutions are overkill, unless it turns out that performance is a problem Thanks Mathew Pierre GM wrote: > Mathew, > Have you tried the solution that was suggested by Angus yesterday on the > numpy > mailing list ? > > http://projects.sci

Mathew, Have you tried the solution that was suggested by Angus yesterday on the numpy mailing list ? http://projects.scipy.org/pipermail/scipy-user/2008-February/015418.html >>> import numpy as np >>> import matplotlib.nxutils as nxutils >>> polygon=np.array([(0,0),(0,1),(1,1),(1,0)]) >>> point

Re: [Matplotlib-users] how to tell if a point is inside a polygon

If you can convert your polygon to a path, you can use the "contains_point" method: >>> from matplotlib import path >>> p = path.Path([[0,0], [42, 3], [45, 23], [1, 32]]) >>> p.contains_point([5,5]) 1 >>> p.contains_point([72, 3]) 0 Mike Mathew Yeates wrote: > Is there a routine in matplotl

[Matplotlib-users] how to tell if a point is inside a polygon

Is there a routine in matplotlib for telling whether a point is inside a convex 4 sided polygon? Mathew - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applicat
