There was something like this in C# I ran into a while back.
What it does
It reconstructs images using polygons
How I built it...
Challenges I ran into
Everything. Such as the fact that you have to press a button exactly seven times on android to enable dev mode for usb debugging. And the fact that tango's java api has such low-level drawing based on open-gl.
Accomplishments that I'm proud of
Submitting stuff. Also, getting to know other people.
What I learned
Getting stuff to work is really hard. Also 75% of hackathons are fixing bugs, configuration, and using Stack Overflow to look up what is causing errors.
What's next for PolyPlaster
Implement better color accuracy difference testing
