A wireframe, Augmented Reality globe, using coastline lat. / lon. values pulled from this site: http://rimmer.ngdc.noaa.gov/
Learning how to move from lat./lon pairs to 3D points was interesting. Extracting these from a CVS file and then into processing was another interesting point. Thankfully most of this work I did plotting stuff for work.
I'm planning on using this to plot genuine lat/lon pairs onto an Augmented Reality globe - possibly plotting Flickr photographs or twitter posts.
A quick play with the Augmented Reality library for Processing. Couldn't think of anything in particular I wanted to use it for so I threw in the fireflies. Nice little library, though access to some of the more complex functionality is missing. The frame rate on the video seems a bit off.
