This project examined how three-dimensional graphics could be used to visualize computer programs, algorithms, and computations. We created a 3D library and toolkit called POLKA-3D that can be used to build animations of computations.

Pictured above is a 3d view of a quicksort algorithm. The blue dots to the right represent the values being sorted, and the multicolored planes to the left provide a history of the exchanges in the program.
