trip-let

A simple command-line application to build Trip-lets.

A trip-let is a three-dimensional solid that, when projected along three perpendicular axes, produces three letters of the alphabet (or, in general, any other shape). They were popularized in the famous Hofstadter's book Gödel, Escher, Bach: An Eternal Golden Braid.

This application produces a trip-let given its three projections.

trip-let -x data/square.png -y data/circle.png -z data/triangle.png -o trisquarcle.obj --find-best-transform

TO DO

Still many things to polish:

• Proper handling and error checking of sizes of input images

• Add the option of saving reprojection errors for debugging

• Add help strings for the arguments of argparse

• Write a brief manual

• A GUI?
