Lines vs. Curves

Filed under: Uncategorized — Jeremy White @ 2:13 pm

Building off of the gradient line segment post from last week, I took the straight line segments and placed them over an unprojected base map.  The resulting flipbook of images was  then mapped onto a polygonal sphere which curved the lines according to their direction and length.

It’s unclear to me whether or not the lines are actually great circles.  The original path for the lines were not based on a spherical calculation, but the resulting paths would indicate otherwise.

  1. Attractive work.
    My concern — and I’ll bring this up during seminar, is that I’m having trouble coming away with anything coherent I can say about this. I learned that there are a lot of tweets going around between different places…but overall patterns are harder to pick out without watching many times.
