[matplotlib-devel] Marching Squares Algorithm

[Curtis C. <cu...@hi...>]

Dear Mr. Horton:

I am investigating options for creating 2D contour plots for the freely
distributable Matplotlib package (http://matplotlib.sourceforge.net/).
The Matplotlib license requires all the software to be free for
noncommercial and commercial distribution.

I had the idea to try to implement marching squares for this package.  We
know the marching cubes algorithm is patented, but what about the 2D
marching squares?  Can my implementation be used in this freely
distributed package without obtaining a license grant?

Thanks,
Curtis
