Augmented Reality for 3D Printing

My roommate’s struggles designing his first 3D printed part gave me the idea to write an augmented reality viewer that lets you preview and interact with STL models in the real world without having to commit an object to plastic. This is actually sort of an update on part of a project I did for a Computational Photography course three years ago, but not terrible looking this time. I used the ArUco library to track the fiducial markers, largely because there is a javascript version if I ever want to make it web based. The program, which I uncreatively named arstl, reads in ASCII and binary STL files and displays them on top of the tracked marker. Right now, it uses a pretty basic OpenGL shader for a shiny plastic look, but I plan on making a more convincingly plastic one with bump mapping and subsurface scattering soon. As usual, the code is up on github under an ISC License. The STL parsing part of it is in the public domain, in case anyone finds it useful.

Augmenting Reality with Reality

I combined voxel carving and augmented reality to insert 3d reconstructions of real life objects into real life scenes for a final project for 15-463, Computational Photography.  There is a more detailed writeup here.  It looks kind of bleh at the moment, and it involves a lot of hacked together libraries.  I really like the idea of it though, so this is something I’m planning on revisiting when I have more skill in the third dimension.
