MDI is my 3D graphics experiment. The idea is to take datasets that have several attributes, and define multiple mappings of their attributes into various forms of 3D spatial coordinate systems. Once the mappings are defined, the user can switch and transition among them and observe how relationships among data items change.
2015-11-27: The basic framework works for two mappings.
2016-01-31: The primary functions have been completed: multiple maps, saving & loading maps, saving & loading apps, attaching one background image to a map (with transparency). Remaining functions include picking objects, centering a picked object, displaying data for a picked object, editing data for a picked object.
2016-03-18: Susan demonstrated it on part of the turtle-tracking database at Jug Bay. Apparently it made a good impression.
